CONTROL BOX SOFT RESET:
·
Unplugging the Control Box from the power source, and then plugging it back in, interrupts power to the
processor inside the Control Box. This power interruption causes the processor to reset.
·
If the Desk experiences unexplained freezing or erratic performance, unplug the Control Box from the
power source to cut power to the processor, and reset its routine. Wait a minimum of 5 seconds, and then
re-connect the power.
·
If this does not restore normal performance, additional troubleshooting steps are required.
CONTROL BOX RE-INITIALIZATION:
·
In the event that a 'Soft Reset' does not restore normal operation, a 'Hard Reset' may be required.

Currently, it is necessary to use a Digital / Preset Controller to perform this operation.

3) Press and hold the Up button until the display reads 'S0'
4) Press 'S'; the unit is reset to factory settings
