Chair power is controlled by the Mains On/Off button on the power supply (see Figure 5). This On/Off button provides power to the chair, as well as any attached modules (including delivery system, dental light, cuspidor, and other support systems). To access the button and power supply, pull the utility cover out at the cover posts and lift the cover off (Figure 5 below and Figure 6 on page 6). The button can remain in the On position overnight, although you may choose to turn it off during longer periods of non-use. The button should always be turned off before service. Figure 5.

Basic Operation „

Touchpad Chair Controls Your touchpad chair controls (see Figure 8) work similarly to the footswitch, but vary depending on your delivery system. To use and program chair functions on your touchpad, please reference the Instructions For Use that came with your delivery system. Figure 8. A-dec Touchpad Examples

Note: Touchpad symbols are proprietary to A-dec Inc.

Patient Positioning Your chair features one of two choices of backrest: a thin-line back with patientadjustable neck support or a thin-line back with double-articulating headrest.

Patient-Adjustable Neck Support Backrests with the integrated, neck support cushion (see Figure 9) allow for easy adjustment by the patient or staff. When the patient is seated, ensure that the neck cushion is in the correct position. Place the cushion below the occipital bone for patient neck comfort. Properly positioned, the cushion glides with the patient to provide comfort as the chair is raised or lowered. Figure 9. Neck Support

The neck support can be repositioned in the track to accommodate shorter or taller patients (see Figure 10). To reposition, place your thumb against the neck support armature and pull the cushion out from the track. Flip the cushion around and snap back into the track. The cushion includes a graphic on the back that depicts proper orientation for shorter or taller patients. Figure 10. Reposition Neck Support C B

Figure 12. Double-Articulating Headrest Positioning

Headrest Adjustment The double-articulating headrest offers a “glide” feature, as well as manual articulation (see Figure 12). The locking knob allows you to easily adjust the headrest for a full range of positions. Release the headrest by turning the locking knob to the left, then adjust the headrest for a proper fit. Lock the headrest in the desired position by turning the knob to the right. For minor height adjustment, slide the headrest cushion up and down. For additional height adjustment, reposition the glide bar. DANGER When the glide bar has reached its maximum recommended working

height, a warning will be visible on the patient’s side of the glide bar. Do not use the headrest in a position where this warning is visible.

How to Position for Wheelchairs The double-articulating headrest can be used to accommodate patients in wheelchairs, as shown in Figure 13. Figure 13. Positioning For Wheelchairs

To position the headrest for wheelchairs: 1. Slide the headrest glide bar up until it is free from the dental chair. 2. Rotate the headrest 180° and slide the glide bar into the backrest. Ensure that the glide bar is pushed completely into the backrest. 3. Position the dental chair to its full back-up position. 4. Once the headrest is repositioned, adjust the height by moving the dental chair up or down. The patient should be positioned so the wheelchair and the dental chair are back to back. 5. Ensure that the wheels of the wheelchair are locked.

Two-Position Armrests The armrests are simple to use and allow the patient to easily access the chair. Pull or push the armrests to reposition them in the forward or back position (see Figure 14). Figure 14. Positioning Armrests

The armrests can also be locked into the upright position (see Figure 19 on page 15).

Removing Upholstery The design of the upholstery makes removing and replacing it quick and easy. The upholstery on your chair is installed in three sections: back, seat, and headrest.

Back Upholstery To remove the back upholstery, firmly grasp the bottom edge of the cushion and lift upward (approximately 1 inch or 25 mm), then lift the upholstery away from the chair back (see Figure 15). To reattach the back upholstery, place the key holes on the armature over the large fastener heads then push down until the upholstery stops in the correct position. Figure 15. Removing the Backrest

The pin ring should be flush with the seat armature.

Double-Articulating Headrest Upholstery To remove the headrest upholstery, position the headrest to access the two screws on the back, loosen screws, and remove upholstery (see Figure 17). To reattach the headrest upholstery, position the headrest to access the screws, place the upholstery on the headrest, insert and tighten the screws. Figure 17.

Adjustments „

Headrest Glidebar Tension If the headrest drifts downward, or if it is difficult to move up or down, the glide bar tension can be adjusted. To adjust the tension, use a 1/8'' (3 mm) hex key and turn the tension adjustment screw to the right to increase friction or left to decrease friction (see Figure 18). Figure 18. Drift Adjustment

Convert to Fixed Armrests The armrests can be locked in an upright position. Using a hex key, remove the rotational stop screw from the front of the armrest and install it in the back of the armrest (see Figure 19). Figure 19. Fixed Armrests A
