Cuspidor Position Return Mode allows operator to program a stored position on button 4 for a patient cuspidor position. Pressing button 4 not only moves chair into position for patient to use cuspidor but also activates cuspidor solenoid output on chair PCB.

Output, (J13 on p.c. board), can be attached to an optional cuspidor solenoid for automatic bowl flush.
When button 4 is pressed and chair begins to move to cuspidor position, automatic bowl flush is activated. When cuspidor position is reached, power is removed from cuspidor solenoid. Pressing button 4 again, returns chair to the last position used before cuspidor position

Last Position Return

Last Position Return Mode allows user to move between two Remembered positions. A Remembered Position is a position stored by chair software anytime chair has set motionless for at least 1/2 second. Pressing button 4 will move chair to last remembered position. Pressing button 4 again toggles the chair between the last two Remembered positions

Calibration Procedure

The purpose of Calibration Mode is to determine the end of travel potentiometer sensors settings, store them in the PCB software, and use this stored information to keep any movement slightly inside these settings or limits.

Calibration is an automatic routine. During calibration the chair completes two cycles. The first cycle finds the extreme end of travel sensor settings. The second cycle checks to assure the settings have been successfully stored and that they can be recalled by the software
