|When the unit is on, hold down programmable buttons 1 and 2 along with the suspend switch until the units beeps. The unit's settings have now been reset.|
Engineering reset should only be used if the unit's settings give an invalid output from which the user cannot exit.
All settings except changes to the image parameter data will be lost following an Engineering Reset.
A more complete 'Factory Reset' is to perform an update to the latest firmware revision - see C2-4000 & C2-5000 series firmware updates.
