tiple pivot points make the positioning of the lighthead easy and flexible. Features The Model 354 lighting system . . . • has a power supply with three input taps, allowing the voltage output to the light bulb to be adjusted according to the particular input voltage available at a facility. This prevents premature failure of the light bulb and lighthead com- ponents as well as unsatisfactory performance. • has a peak illumination of 4,000 fc (43,000 lux) at 36 in. (91.4 cm), but can be adjusted to a lower intensity (brightness) if desired. • provides a round beam of light which can be adjusted from a diameter of 3 in. to 10 in. (7.6 to 25.4 cm) - based on a distance of 36 in. (91.4 cm) from surface being lit. • has two joint pivots with 580° of rotation, one pivot joint with 540° of rotation, and one pivot joint with 180° of rotation making positioning of the lighthead easy and flexible. • has an arm reach of 48 in. (122 cm) (from centerline of down tube to center of lighthead). • is precisely balanced so that the lighthead can be positioned with minimal force and no drifting will occur. • has a plastic handle which can be easily removed for sterilization or it accepts a Devon EZ Handle™.

EQUIPMENT ALERT Do not obstruct the airflow of the lighthead or damage to lighthead could result. If the 354 light system malfunctions, immediately turn the ON / STANDBY switch to STANDBY “ “. Controls & Indicators Operation

The following preventive maintenance schedule should be followed. If a prob- lem is detected, refer to the troubleshooting guide in this manual. Troubleshooting Guide If there is a malfunction with the light system, use the troubleshooting guide to correct the problem. Refer to the illustrations in the Components Overview and Controls & Indicators sections of this manual as necessary. FREQUENCY ACTIVITY semiannually Inspect rotation of lighthead. Make sure the lighthead rotates freely, without noise, and has 180° of rotation at lamp tube con- nection. Make sure the lighthead stays positioned at any point (without drifting) with respect to the lamp tube. semiannually Inspect the rotation of the lamp tube, cross tube, and down tube. Make sure the arm assemblies rotate freely and without noise. Make sure the arm assemblies don’t drift at any point in their range of motion. The lamp tube should have 540° of rotation at cross tube connection. The cross tube should have 580° of rota- tion at down tube connection and should also have a vertical range of motion from -35° to +35°. The down tube should have 580° of rotation at ceiling mount connection. semiannually Turn light ON “I”. Rotate lighthead, lamp tube, cross tube, and down tube while observing lighthead. The lighthead should not intermittently flicker or stop illuminating while joints are being ro- tated. semiannually Check for excessive joint rotation (more than 540° or 580° of ro- tation). The physical hard stops for an axis may be broken. semiannually Inspect inside of lighthead for indications of broken material or other signs of damage. If damage to any part of lighthead is evident, do not continue to use lighthead. semiannually Turn light ON “I”. Verify that fan is operating. If fan is not operat- ing, do not continue to use lighthead. Operating lighthead with- out a fan in operation may cause lenses to melt.
