Troubleshooting
5.3 5300 Viewing Angle
If no characters or all characters appear in the display, the viewing angle may be
improperly adjusted. If the display is difficult to read from the angle you normally view it,
the viewing angle can be adjusted as follows: Press and hold the last option switch above
the display and then press the first option switch above the display. Release both switches
and turn the Select switch until the best contrast is obtained. This function times out in
three to five seconds.
5.4 5300 User Troubleshooting
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
transceiver.
If the transceiver is completely inoperative, check the power cable fuse that is usually
located near the vehicle battery. If it is blown, remedy the cause if possible and replace it
with the same type (15A). If the transceiver still does not operate properly, return it to your
system operator for service.
5.5 User Troubleshooting
If UNPROGRAMD” is displayed, the cause could 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. The radio needs to be reprogrammed.
