Factory Default Routine

When a new circuit board is installed in the chair, the circuit board needs to run the factory default routine to learn the range of motion of the chair.

The routine:

•sets the base and back upper limits

•calculates new presets based on actual range of motion of the chair

•verifies that the potentiometers work

To start the factory default routine, place the “spare” jumper in the factory default position on the P3 test points of the chair circuit board.

85.0816.00 Rev B 2007-04

Service/Usage Information Factory Default Routine

When running the factory default routine the chair:

1.Moves base down

2.Moves base up

3.Moves back down

4.Moves back up

5.Moves base and back to Position 0

6.Beeps three times

NOTE The jumper must remain in the factory default position to complete the factory default routine. The status LEDs on the standard and deluxe touchpads and the chair circuit board double blink while the factory default routine is running and after the routine is complete.
