LED

Figure 1. Lift, Tilt, and Stop Plate

Chair LED The chair LED indicates the status of the chair: ON: Normal operation. SLOW BLINK: The cuspidor or stop plate limit switches have been activated. Remove any obstructing object.

Chair Stop Plate The chair stop plate (see Figure 1) stops the chair immediately when any part of it is pressed. Should anything inadvertently become lodged under the chair, press Base UP on the footswitch or touch pad to raise the chair so the object can be removed. As long as pressure is applied to the stop plate, the chair base will not go down any further. 2
