Service/Usage Information Factory Default Routine
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.
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.
