Returning the Vehicle Computer for Service
Troubleshooting
.
NOTE Motorola has taken great care to ensure environmental conditions such as humidity will not affect the stability
of the vehicle computer. This is accomplished my means of desiccant bags which can be inserted by the user
upon receipt of the vehicle computer. In the event, the vehicle computer needs to be shipped by air carrier to
Motorola for repair or maintenance, it is essential that the user remove the desiccant door cover before the
vehicle computer is packaged for shipment. The reason for this step is to avoid compromising the vehicle
computer as a result of pressurization during air transit. The user must simply remove the screws associated
with the desiccant door on the back of the unit. Discard the used desiccant bags. Upon receipt of the repaired
vehicle computer, the user should insert new desiccant bags (if used) and reseal the doors using new screws.
