errors in the software program by following sound engineering design processes, risk analysis and software validation. ■ Explosion hazard. Do not use the pulse oximeter in the presence of flammable anes- thetics or other flammable substance in combination with air, oxygen-enriched environ- ments, or nitrous oxide. ■ High intensity extreme lights (such as pulsating strobe lights) directed on the sensor, may not allow the pulse oximeter to obtain vital sign readings. ■ The pulse oximeter is NOT intended for use as an apnea monitor. ■ A pulse oximeter should be considered an early warning device. As a trend towards patient hypoxemia is indicated, blood samples should be analyzed by laboratory instruments to completely understand the patient’s condition. ■ The pulse oximeter is to be operated by qualified personnel only. This manual, acces- sory directions for use, all precautionary information, and specifications should be read and understood before use. ■ Electric shock hazard. Do not open the pulse oximeter cover except to replace the battery of the unit. Only a qualified operator may perform maintenance procedures specifically described in this manual. Refer servicing to Masimo for repair of this equipment. ■ Only a qualified operator may perform maintenance procedures specifically described in this manual. Refer servicing to Masimo for repair of this equipment. ■ As with all medical equipment, carefully route patient cabling to reduce the possibility of patient entanglement or strangulation. ■ Do not place the pulse oximeter or accessories in any position that might cause it to fall on the patient. Do not lift the pulse oximeter by the patient cable. ■ Interfering Substances: Carboxyhemoglobin and Methemoglobin may erroneously increase readings. The level of increase is approximately equal to the amount of car- boxyhemoglobin present. Dyes, or any substance containing dyes, that change usual blood pigmentation may cause erroneous readings. ■ Severe anemia may cause erroneous SpO2 readings. ■ Do not use the pulse oximeter or oximetry sensors during magnetic resonance imaging (MRI) scanning. Induced current could potentially cause burns. The pulse oximeter may affect the MRI image, and the MRI unit may affect the accuracy of the oximetry measurements. ■ If using pulse oximetry during full body irradiation, keep the sensor out of the irradiation field. If sensor is exposed to the irradiation, the reading might be inaccurate or the unit might read zero for the duration of the active irradiation period. ■ Always remove the sensor from the patient and completely disconnect the patient from the pulse oximeter before bathing the patient. ■ Do not place the pulse oximeter where the controls can be changed by the patient. ■ Do not place the pulse oximeter face against a surface. This will cause the alarm to be muffled. ii Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual iii ■ Do not place the pulse oximeter on electrical equipment that may affect the pulse oximeter, preventing it from working properly. ■ Do not expose the pulse oximeter to excessive moisture such as direct exposure to rain. Excessive moisture can cause the pulse oximeter to perform inaccurately or fail. ■ Do not place containers containing liquids on or near the pulse oximeter. Liquids spilled on the pulse oximeter may cause it to perform inaccurately or fail. ■ Failure of Operation - If the pulse oximeter fails any part of the setup procedures remove the pulse oximeter from operation until qualified service personnel have corrected the situation. ■ Patient Safety - If a sensor or cable is damaged in any way, discontinue use immediately. ■ Disposal of product - Comply with local laws in the disposal of the unit and/or its accessories. ■ The pulse oximeter can be used during defibrillation, but the readings may be inac- curate for up to 20 seconds. ■ This equipment has been tested and found to comply with the limits for medical devices to the EN 60601-1-2: 2002, Medical Device Directive 93/42/EEC. These limits are designed to provide reasonable protection against harmful interference in a typical medical installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to other devices in the vicinity. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to other devices, which can be determined by turning the equip- ment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: ■ Reorient or relocate the receiving device. ■ Increase the separation between the equipment. ■ Consult the manufacturer for help. ■ A functional tester cannot be utilized to assess the accuracy of the pulse oximeter or any sensors.

1-5 1 o v e r v i e w o v e r v i e w 1-4 Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual 1 FUNCTIONAL VS. FRACTIONAL SATURATION The Rad-8 is calibrated to measure and display functional saturation which is the amount of oxygenated hemoglobin expressed as a percentage of the hemoglobin that can transport oxygen. The Rad-8 does not measure fractional saturation which is oxygenated hemo- globin expressed as a percentage of all measured hemoglobin. This includes measured dysfunctional hemoglobin such as carboxyhemoglobin or methemoglobin. To convert fractional saturation to functional saturation, the fractional saturation measurements must be converted according to: Functional saturation = Fractional saturation x 100 100 - (% carboxyhemoglobin + % methemoglobin) MEASURED VS. CALCULATED SATURATION Oxygen saturation measurements obtained from a pulse oximeter are commonly com- pared to saturations calculated from the partial pressure of oxygen (PO2) obtained from an arterial blood gas sample. When comparing the two measurements and interpreting values, caution should be used, as the calculated value obtained from the blood gas sample may differ from the SpO2 measurement of the pulse oximeter. Different results are usually obtained from the blood gas sample if the calculated saturation is not appropriately corrected for the effects of variables that shift the relationship between PO2 and satura- tion, such as: pH, temperature, the partial pressure of carbon dioxide (PCO2), 2,3-DPG, and fetal hemoglobin. Also, as blood gas samples are usually taken over a period of 20 seconds (the time it takes to draw blood) a meaningful comparison can only be achieved if the core oxygen saturation of the patient is stable and not changing over the period of time that the blood gas sample is taken. MASIMO SET SIGNAL EXTRACTION TECHNOLOGY Masimo Signal Extraction Technology’s signal processing differs from conventional pulse oximeters. Conventional pulse oximeters assume that arterial blood is the only blood mov- ing (pulsating) in the measurement site. During patient motion, however, the non-arterial blood also moves, causing conventional pulse oximeters to read low values, because they cannot distinguish between the arterial and venous blood movement (sometimes referred to as noise). Masimo SET pulse oximetry utilizes parallel engines and adaptive digital filtering. Adaptive filters are powerful because they are able to adapt to the varying physi- ologic signals and/or noise and separate them by looking at the whole signal and breaking it down to its fundamental components. The Masimo SET signal processing algorithm, Discrete Saturation Transform ® (DST) ®, reliably identifies the noise, isolates it and, using adaptive filters, cancels it. It then reports the true arterial oxygen saturation for display on the monitor. P u l s e O x i m e t r y GENERAL DESCRIPTION Pulse oximetry is a continuous and non-invasive method of measuring the level of arterial oxygen saturation in blood. The measurement is taken by placing a sensor on a patient, usually on the fingertip for adults, and the hand or foot for neonates. The sensor connects to the pulse oximetry instrument directly or with a patient cable. The sensor collects signal data from the patient and sends it to the instrument. The instrument displays the calculated data in two ways: 1. As a percent value for arterial oxygen saturation (SpO2) and 2. As a pulse rate (PR). The following figure shows the general monitoring setup. PRINCIPLE OF OPERATION Pulse oximetry is governed by the following principles: 1. Oxyhemoglobin (oxygenated blood) and deoxyhemoglobin (non-oxygenated blood) differ in their absorption of red and infrared light (spectrophotometry). 2. The amount of arterial blood in tissue changes with your pulse (photoplethysogra- phy). Therefore, the amount of light absorbed by the varying quantities of arterial blood changes as well. The Rad-8 pulse oximeter uses a two-wavelength pulsatile system to distinguish between oxygenated and deoxygenated blood. Signal data is obtained by passing red (rd) (660 nm wavelength) and infrared (ir) (905 nm wavelength) light through a capillary bed (for example a fingertip, a hand or a foot) and measuring changes in light absorption during the pulsatile cycle. This information may be useful to clinicians. The radiant power of the light is rated at 0.79mW (max.). See figure below. The Rad-8 utilizes a sensor with red and infrared light-emitting diodes (LEDs) that pass light through the site to a photodiode (photodetec- tor). The photodetector receives the light, converts it into an electronic signal and sends it to the Rad-8 for calculation. Once the Rad-8 receives the signal from the sensor, it utilizes Masimo SET signal extrac- tion technology for calculation of the patient’s functional oxygen saturation and pulse rate. The maximum of the skin surface temperature is measured at an ambient temperature of less than 106º F (41º C).This is verified by Masimo sensor skin temperature test proce- dures. 1. Instrument 2.

4-1 4 o p e r a t i o n I n t r o d u c t i o n To operate the Rad-8 pulse oximeter effectively, the operator must: ■ Know how the oximeter derives its readings (see Section 1, Pulse Oximetry) ■ Be familiar with its controls and operation. ■ Understand its status and alarm messages (see Section 5, Alarm Identification, System Messages and Section 6, Troubleshooting). B a s i c o p e r a t i o n GENERAL SETUP AND USE 1. Inspect the oximeter case for damage. 2. Connect a patient cable or a direct connect sensor to the Patient Cable Connector of the Rad-8 pulse oximeter. Make sure it is a firm connection and the cable is not twisted, sliced or frayed. 3. If utilizing a patient cable, select a sensor that is compatible with the oximeter and the patient before connecting it to the patient cable. See Section 8, Sensors and Patient Cables. If using a reusable sensor, make sure it opens and closes smooth- ly. Remove any substances that may interfere with the transmission of light between the sensor’s light source and photodetector. 4. Refer to the Directions for Use of the sensor before attaching the sensor to the patient. If using a single patient adhesive or disposable sensor, check that the emit- ter (red light) and the photodetector are properly aligned. 5. With a single patient adhesive or disposable sensor, connect the sensor to the patient cable with the logos lining up; make sure it is a firm connection. 6. Press the Power button to turn the oximeter on. 7. Verify all front-panel indicators momentarily illuminate and a tone is heard. 8. Verify the front-panel display is free of alarm and system failure messages (see Section 5, Alarms and Messages). 9. Verify the display shows the following: ■ Mode setting: Standard (Std) or Sleep (SLP) or Home (Hnn) ■ SpO2 Low Alarm Limit and SpO2 High Alarm Limit, ■ Pulse Rate Low Alarm Limit and Pulse Rate High Alarm Limit, ■ Averaging Time. 10. On the display, verify the readings for SpO2 and pulse rate. NOTE: “- - -” will flash on the numeric display until the SpO2 and pulse rate readings have stabilized (approximately 10 seconds). ■ IF THERE IS ANY DOUBT ABOUT THE INTEGRITY OF THE PROTECTIVE EARTH CON- DUCTOR ARRANGEMENT, OPERATE THE OXIMETER ON INTERNAL BATTERY POWER UNTIL THE AC POWER SUPPLY PROTECTIVE CONDUCTOR IS FULLY FUNCTIONAL. ■ TO ENSURE PATIENT ELECTRICAL ISOLATION, CONNECT ONLY TO OTHER EQUIPMENT WITH ELECTRICALLY ISOLATED CIRCUITS. ■ DO NOT CONNECT TO AN ELECTRICAL OUTLET CONTROLLED BY A WALL SWITCH OR DIMMER. INITIAL BATTERY CHARGING Before use, the Rad-8 battery needs to be fully charged. To charge the internal battery, plug in the AC power cord. Verify that the battery is charging. The green battery charging LED indicator on the unit will remain illuminated while the battery is charging. INITIAL INSTALLATION Place the Rad-8 on a stable hard flat surface near the patient.

4-5 4 o p e r a t i o n NUMERIC DISPLAY - PULSE RATE The Pulse Rate displayed on the Rad-8 may differ slightly from the heart rate displayed on ECG monitors due to differences in averaging times. There may also be a discrepancy between cardiac electrical activity and peripheral arterial pulsation. Significant differences may indicate a problem with the signal quality due to physiological changes in the patient or one of the instruments or application of the sensor or patient cable. The pulsations from intra-aortic balloon support can be additive to the pulse rate displayed on the pulse oximeter. S u c c e s s f u l S p O 2 m o n i t o r i n g The following general points will aid in ensuring oximetry monitoring success. ■ Place the sensor on a site that is not too thick, has sufficient perfusion and provides proper alignment of the LED’s and photodetector. ■ Place the sensor on a site that has unrestricted blood flow. ■ Do not select a site near potential electrical interference (electrosurgical unit, for example). ■ Read the sensor Directions for Use for proper sensor application. NUMERIC DISPLAY - SpO2 Stability of the SpO2 readings may be a good indicator of signal validity. Although stability is a relative term, experience will provide a good feeling for changes that are artifactual or physiological and the speed, timing, and behavior of each. The stability of the readings over time is affected by the averaging mode being used. The longer the averaging time, the more stable the readings tend to become. This is due to a dampened response as the signal is averaged over a longer period of time than during shorter averaging times. However, longer averaging times delay the response of the oximeter and reduce the mea- sured variations of SpO2 and PR. MASIMO SENSORS Before use, carefully read the LNOP, LNOPv and LNCS sensor Directions for Use. Use only Masimo oximetry sensors for SpO2 measurements. Tissue damage can be caused by incorrect application or use of an LNOP, LNOPv or LNCS sensor, for example by wrapping the sensor too tightly. Inspect the sensor site as directed in the sensor Directions for Use to ensure skin integrity and correct positioning and adhesion of the sensor. CAUTIONS ■ DO NOT USE DAMAGED SENSORS. DO NOT USE A SENSOR WITH EXPOSED OPTICAL OR ELECTRICAL COMPONENTS. DO NOT IMMERSE THE SENSOR IN WATER, SOLVENTS, OR CLEANING SOLUTIONS (THE SENSORS AND CON- NEC TORS ARE NOT WATERPROOF). DO NOT STERILIZE BY IRRADIATION, STEAM, AUTOCLAVE OR ETHYLENE OXIDE (UNLESS OTHERWISE INDICATED ON THE SENSOR DIRECTIONS FOR USE). SEE THE CLEANING INSTRUC- TIONS IN THE DIRECTIONS FOR USE FOR REUSABLE MASIMO SENSORS. ■ DO NOT USE DAMAGED PATIENT CABLES. DO NOT IMMERSE THE PATIENT CABLES IN WATER, SOLVENTS, OR CLEANING SOLUTIONS (THE PATIENT CABLE CONNECTORS ARE NOT WATERPROOF).

4-7 4 o p e r a t i o n LOW PERFUSION The Rad-8 indicates perfusion on a 10-bar LED indicator. The lower two segments of the bar will turn red when the amplitude of the arterial pulsations is very low (low perfusion). It has been suggested that at extremely low perfusion levels, pulse oximeters can measure peripheral saturation, which may differ from central arterial saturation1. This “localized hypoxemia” may result from the metabolic demands of other tissues extracting oxygen proximal to the monitoring site under conditions of sustained peripheral hypoperfusion. (This may occur even with a pulse rate that correlates with the ECG heart rate.) CAUTION: IF THE LOW PERFUSION INDICATION IS FREQUENTLY DISPLAYED, FIND A BETTER-PERFUSED MONITORING SITE. IN THE INTERIM, ASSESS THE PATIENT AND, IF INDICATED, VERIFY OXYGENATION STATUS THROUGH OTHER MEANS. 1 Severinghaus JW, Spellman MJ. pulse oximeter Failure Thresholds in Hypotension and Vasoconstriction. Anesthesiology 1990; 73:532-537 ACTIONS TO BE TAKEN If the SpO2 readings show significant differences, do the following: ■ Make sure the emitter and photodetector are aligned directly opposite each other. ■ Select a site where the distance between the emitter and photodetector is mini- mized. ■ Wipe the sensor site with a 70% isopropyl alcohol pad or rubefacient cream (10- 30% methyl salicylate and 2-10% menthol) for 20-30 seconds. Strong vasodilator creams, such as nitroglycerin paste, are not recommended. ■ If possible, remove electrical noise sources such as electrosurgical units or other electrical/electronic equipment. ■ If artificial nails or excessive fingernail polish are present, select another site or remove the polish/artificial nails. ■ If possible, ensure that the sensor is placed in a location with low ambient light. Although the Rad-8 pulse oximeter integrated with Masimo SET technology has significant immunity to ambient light, excessive ambient light may cause readings to be incorrect. CAUTION: IF ANY MEASUREMENT SEEMS QUESTIONABLE, FIRST CHECK THE PATIENT’S VITAL SIGNS BY ALTERNATE MEANS AND THEN CHECK THE PULSE OXIMETER FOR PROPER FUNCTIONING. SIGNAL IQ AND PULSE BAR The Rad-8 display provides a visual indicator of the plethysmogram signal quality and an alert when the displayed SpO2 values are not based on adequate signal quality. The signal quality indicator displayed on the Rad-8 is called the Signal IQ. The Signal IQ can be used to identify the occurrence of a patient’s pulse and the associated signal quality of the measurement. The Signal IQ is shown as a “bouncing bar” indicator, where the peak of the bar coincides with the peak of an arterial pulsation. Even with a plethysmographic waveform obscured by artifact, the Rad-8 locates the arterial pulsation. The pulse tone (when enabled) coincides with the peak of the Signal IQ bar. As saturation increases or decreases, the pulse tone will ascend or descend accordingly, for each 1% change in saturation. The height of the Signal IQ bar indicates the quality of the measured signal. A high verti- cal bar indicates that the SpO2 measurement is based on a good quality signal. A small vertical bar indicates that the SpO2 measurement is based on data with low signal quality. When the signal quality is very low the accuracy of the SpO2 measurement may be com- promised. A “Low Signal IQ” is indicated by a bar height of two bars or less and the bars turn red. When this occurs, proceed with caution and do the following: ■ Assess the patient. ■ Check the sensor and ensure proper sensor application. The sensor must be well secured to the site for the Rad-8 to maintain accurate readings. Also, misalignment of the sensor’s emitter and detector can result in smaller signals. ■ Determine if an extreme change in the patient’s physiology and blood flow at the monitoring site occurred, (e.g. an inflated blood pressure cuff, a squeezing motion, sampling of an arterial blood specimen from the hand containing the pulse oximetry sensor, severe hypotension, peripheral vasoconstriction in response to hypothermia, medications, or a spell of Raynaud’s syndrome.) ■ With neonates or infants, check that the peripheral blood flow to the sensor site is not interrupted. Interruption, for example, as may occur while lifting or crossing their legs, during a diaper change. After performing the above, if the “Low Signal IQ” indication occurs frequently or continu- ously, obtaining an arterial blood specimen for CO-Oximetry analysis may be considered to verify the oxygen saturation value. o p e r a t i o n 4-6 Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual 4

Audible alarms may be silenced, without affecting the operation of visual alarms. Two levels of alarm priority are implemented: high and low priority. The following table out- lines the alarm priority specifications. ALARM PRIORITY PARAMETER ALARM TYPE High Low saturation (SpO2 range 1-100%) Audible and visual System failures High pulse rate (pulse rate range 30-240 bpm) Low pulse rate (pulse rate range 25-235 bpm) Sensor off and no sensor Low Low battery High saturation (SpO2 range 2-100%) A l a r m i n d i c a t i o n An alarm condition is indicated by: ■ Audible alarm tone ■ Visual Alarm Indicator ■ Out-of-limit parameter will flash “no sensor” and “sensor off” will only generate an alarm condition after a pulse has been found.

Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual 5-3 5 a l a r m s a n d m e s s a g e s ALARM SILENCE Audible alarms may be suspended, while visual alarms may not. With the exception of Sleep Mode, there are two audible alarm suspension settings, all controlled by the Alarm Suspend Button. Repeated pressing of the Alarm Suspend button will cycle though two alarm suspend options. Power-On – Alarms are active and Alarm Suspended Indicator is off. Push Once – Alarm is suspended for 120 seconds and Alarm Suspended Indicator flashes (See section 4 “Alarm features and sensitivity” to adjust alarm suspension time period). Push Twice - Return to Audible Alarm Active. ALARM SILENCED INDICATOR The Alarm Silenced Indicator provides visual feedback when illuminated, the Rad-8 audible alarms are muted. While monitoring a patient, acknowledging an alarm condition by pressing the Alarm Silence Button (one time) will silence the alarm tone for 120 seconds (default) and the Alarm Silenced Indicator will flash. Pressing the Alarm Silence Button a second time (while the Alarm Silenced Indicator is still flashing) will activate alarms and alarm silenced indicator is off. While not monitoring a patient, acknowledging an alarm condition by pressing the Alarm Silence Button (one time) will permanently silence the alarm tone, and the Alarm Silenced Indicator will remain illuminated until the power is cycled or patient monitoring begins. While in the Home Mode and not monitoring a patient, the alarm will be suspended for 120 seconds (default). Should the alarm condition be created by a low battery condition, plug the unit into AC power immediately. a l a r m s a n d m e s s a g e s 5 A l a r m l i m i t s CAUTION: TO ENSURE THAT ALARM LIMITS ARE APPROPRIATE FOR THE PATIENT BEING MONITORED, CHECK THE LIMITS EACH TIME THE PULSE OXIMETER IS USED. An audible alarm and a flashing alarm status indicator will occur when an alarm limit is exceeded for greater than five seconds (See section 4, Alarm Features and Sensitivity to adjust this setting). It is best that the operator be within a minimum of 10 feet from the unit. Directions for alarm suspension are indicated below. When a sensor is not connected to a patient the “no sensor” indicator will illuminate. When a sensor is not connected to its cable, “sensor off” indicator will illuminate. An audible alarm will accompany the visual indicator unless the oximeter has been set to Alarm Suspend Mode. SETTING RANGE SpO2 High Limit The SpO2 high alarm limit can be set anywhere between 2% and 99%, with a 1% step size. In the “----” (off) setting, the SpO2 High Limit alarm is disabled. SpO2 Low Limit The SpO2 low alarm limit can be set anywhere between 1% and 99%, with a 1% step size. NOTE: The low alarm limit must always be set below the high alarm setting. Attempting to set the high alarm limit below the low alarm limit, the low alarm limit will automatically adjust the low limit to the next setting below the newly entered high alarm limit setting. Pulse Rate High Limit (BPM) The pulse rate high alarm limit can be set anywhere between 30 BPM and 240 BPM, with a 5 BPM step size. Pulse Rate Low Limit (BPM) The pulse rate low alarm limit can be set anywhere between 25 BPM and 235 BPM, with a 5 BPM step size. NOTE: The low alarm limit must always be set below the high alarm setting. Attempting to set the high alarm limit below the low alarm limit, the low alarm limit will automatically adjust the low limit to the next setting below the newly entered high alarm limit setting. NOTE: Pressing and holding down the up and down buttons allow for the rapid scrolling of changing SpO2 and BPM alarm limits. NOTE: If there is a loss of power for any length of time, the Alarm settings will be set back to the User set defaults. If the user has not utilized this option, then they will be set back to the factory defaults.

VERIFY THE COMPATIBILIY OF THE MONITOR, CABLE AND SENSOR BEFORE USE, OTHERWISE PATIENT INJURY CAN RESULT. ■ DO NOT USE ADDITIONAL TAPE TO WRAP SENSOR. SELECTING A MASIMO SET SENSOR When selecting a sensor, consider, the patient’s weight, the adequacy of perfusion, the available sensor sites, and the duration of monitoring. For more information refer to the following table or contact your Sales Representative. Use only Masimo SET sensors and sensor cables. Select an appropriate sensor, apply it as directed, and observe all warn- ings and cautions presented in the directions for use accompanying the sensor. High ambient light sources such as surgical lights (especially those with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight can interfere with the performance of an SpO2 sensor. To prevent interference from ambient light, ensure that the sensor is properly applied, and cover the sensor site with opaque material, if required. Failure to take this precaution in high ambient light condi- tions may result in inaccurate measurements. SERIAL PRINTER SETUP To print the SpO2 and pulse rate data in ASCII1 format on a serial printer, simply connect the laser printer to the serial port and set output mode to ASCII1. Once serial communi- cation is established, the Rad-8 automatically will start printing the ASCII1 text data. WARNING: ALL EXTERNAL DEVICE CONNECTIONS TO THE RS-232 SERIAL PORT MUST BE IEC-60950 COMPLIANT. Nurse call specifications The nurse call features are accessible via the 1/4” round female connector on the back of the unit. NURSE CALL The nurse call feature on the Rad-8 pulse oximeter is based on the relay closing or open- ing depending on alarm, Low Signal IQ events or both. In addition the nurse call polarity can be inverted to accommodate various nurse call stations requirements. The nurse call relays have the following electrical specification per switch: PARAMETER SPECIFICATION MAX VOLTAGE 36 VDC or 24 VAC peak WARNING: THE NURSE CALL FEATURE IS DISABLED WHEN THE AUDIBLE ALARMS ARE SILENCED WHILE THE NURSE CALL SETTING IN THE OUT- PUT MENU IS SET TO “ALARMS”. s p e c i f i c a t i o n s 7-4 Rad-8 Signal Extraction Pulse Oximeter Operator’s Manual 7
