DRB III(R) ERROR MESSAGE
Under normal operation, the DRB will display one of only two error messages:
- User-Requested WARM Boot or User Requested COLD Boot

If the DRB III should display any other error message, record the entire display and call the MDS Hotline, or call for information and assistance at 1-800-825-8737. This is a sample of such an error message display:

DRB III(R) does not power up (Blank Screen)
If the LED's do not light or no sound is emitted at start up, check for loose cable connection or a bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts is required to adequately power the DRB.

If all connections are proper between the DRB and the vehicle or other devices, and the vehicle battery is fully charged, an inoperative DRB may be the result of a faulty cable or vehicle wiring. Perform the BLANK SCREEN TEST under Communication.
