3.1.14 Radio Service
If “UNPROGRAMD” is displayed, the cause can be any of the following:
• An unprogrammed channel is selected. Select a programmed channel.
• The selected channel is programmed for an option that is not installed or an error in
programming was detected. Contact your system operator for service.
If the channel is programmed for a system type not programmed, “DISABLED” is
displayed.
If no characters or all characters appear in the display, the viewing angle may be
improperly adjusted. If some other problem is occurring, turn power OFF and then ON
again to reset the control logic. Also make sure that the controls are properly set and that
the power, external speaker, and accessory cables (if used) are securely plugged into the
back of the radio.
If the radio is completely inoperative, check the Main power and ignition sense line fuse.
If it is blown, remedy the cause if possible and replace it with the same type (1A, 15A). If
the radio still does not operate properly, return it to your system operator for service.
Note
There are no user-serviceable components in the radio. Altering internal adjustments can
cause illegal emissions, void the warranty, and result in improper operation that can
seriously damage the radio.
Note
If the vehicle itself needs to be jump started, the mobile fuses must be pulled before jump
starting to prevent damage to the radio!
