Operation of the DRBII (Chassis System)

OPERATION OF THE DRBII (Chassis System)

Once connected to the vehicle and the correct cartridge is plugged in, the DRBII will perform a "Self Test". During this time all segments of the display should turn on, the red and green indicator lamps should turn on, and you should hear a beep. If one of these functions do not occur or the message "hardware failure" appears on the display, the ORBII has a malfunction and must be repaired.

NOTE: During the self test function, make sure that none of the keys on the keypad are pressed.

After a few seconds the displayed message will be:
