Models QT-740 & QT-750 - Operator’s Manual 13 OVERVIEW To provide precise patient positioning, Model QT-740 and QT-750 radiographic tables feature a tabletop that "floats" in four directions; transversely (forward and backward) and longitudinally (left and right). Model QT-750 has the additional capability of tabletop elevation (i.e., the tabletop can be raised and lowered to facilitate patient transfer on and off the table). TABLE CONTROLS WARNING! All movable assemblies and parts of this equipment must be operated with reasonable care. Manufacturer’s equipment recommenda- tions described in this manual must be observed. WARNING! To avoid damage to the table, any load on table top should be distributed as evenly as possible over the support surface. Do not seat patient at extreme ends of tabletop when table- top is not centered. Patients weighing more than approximately 300 lbs. (136 kg) should only be transferred on or off the table from front side - in the center. WARNING! Do not allow patient to place his/her hands along the side or below the table rail. Injury to the patient’s hands and/or fingers is possible. Figure 2. Areas Indicated to Keep Hands/Fingers Away From

14 Models QT-740 & QT-750 - Operator’s Manual TABLETOP FLOAT MOTION (ALL MODELS) Models QT-740 and QT-750 both feature a "floating" tabletop. With the "float- top" function activated, both transverse and longitudinal positioning of the patient is enabled. To operate the float-top function, proceed as follows: WARNING! When transferring a patient on or off the tabletop, always make sure the tabletop is locked. If necessary, the Foot Pedal Disable Switch may be activated to prevent unintended activation of the FLOAT foot pedal control. Figure 3. Patient Positioned on Tabletop FLOAT FOOT PEDAL Figure 4. Model QT-740 FLOAT Foot Pedal Control

Models QT-740 & QT-750 - Operator’s Manual 15 1. Position the patient on the table with his or her hands situated along the side of their body, or with the hands grasping the patient handles (see Figure 3). Be sure that the hands remain above the tabletop. 2. Press the FLOAT foot pedal (see Figures 4 and 5) to enable transverse and/or longitudinal motion of the tabletop. (When the foot pedal is pressed, it releases electromagnets (locks) that prevent transverse and longitudinal tabletop motion.) 3. Releasing the FLOAT foot pedal immediately activates tabletop locks, inhibit- ing transverse and longitudinal tabletop motion. ELEVATING MOTION (MODEL QT-750 ONLY) On Model QT-750 radiographic tables, the elevation function allows the tabletop to be lowered down to as low as 21 inches (533.4 mm) from floor, up to a work- ing height of 32.5 inches (825.5 mm). To operate the tabletop elevation function, proceed as follows: WARNING! For safety purposes, an Emergency Stop Switch (see Figure 6) immediately removes power from the tabletop up/down motor when activated. Rotating the Emergency Stop Switch knob 1/4-turn counterclockwise releases the Emergency Stop Switch and restores power. Figure 5.

It is recommended that the tabletop be centered before lowering it (refer to Tabletop Float Motion operation in preceding para- graph). 2. Press the DOWN foot pedal (see Figure 5) to lower the tabletop to the desired height. 3. Transfer patient onto tabletop. 4. Ensure patient is positioned with his or her hands situated along the side of their body, or with the hands grasping the patient handles (see Figure 3). Be sure patient’s hands remain above the tabletop. Note: As it is lowered, the speed at which the tabletop travels will gradually be reduced until the tabletop reaches the lowest point of travel for optimal patient comfort. RAISING THE TABLETOP 1. Press the UP foot pedal (see Figure 5) to raise the tabletop to the desired height. 2. Proceed with examination. EMERGENCY STOP SWITCH FOOT PEDAL/ FLOAT PUSH BUTTON DISABLE SWITCH Figure 6. Emergency Stop and Pedal Disable Switch Locations NOTE Model QT-750 tables are equipped with Obstruction Sensors, which detect the presence of an obstruction below the tabletop when the tabletop is being driven downward. This feature is only designed to avoid dam- age to the table and is not intended as a safeguard against per- sonal injury.

Models QT-740 & QT-750 - Operator’s Manual 17 FOOT PEDAL/FLOAT PUSH BUTTON DISABLE SWITCH To prevent accidental activation of the foot pedal controls (i.e., FLOAT foot pedal on Model QT-740 and FLOAT, UP, and DOWN foot pedals on Model QT-750) and the FLOAT push button, a Foot Pedal Disable Switch is provided. This switch is located below the front table rail on the left end of the table (see Figure 6). Pressing the switch until the switch light is illuminated disables all foot pedal func- tions (and the FLOAT push button switch). When the Foot Pedal Disable Switch light is not illuminated, the foot pedals and FLOAT push button switch are fully operational. IMAGE RECEPTOR CABINET LOCK The Image Receptor Cabinet rides on four linear ball-bearings mounted to adjust- able brackets attached to either side of the cabinet (see Figure 7). These bear- ings travel on the hardened and polished steel shafts of the Receptor Cabinet Carriage. An electromagnet on the underside of the housing "locks" the cabinet into place until the LOCK RELEASE switch is depressed, thereby releasing the magnet’s hold and allowing free movement of the cabinet. CASSETTE TRAY OPERATION The radiographic table is equipped with either a Midwest or Poersch cassette tray, depending on the system ordered. The following paragraphs describe the operat- ing instructions for each. Additional information is contained in the cassette tray manufacturer’s documentation, which is provided with the table.
