Since power consumption is significantly higher when transmitting, it is good practice to
have the vehicle running while transmitting. This ensures that optimum power is being
delivered to the radio and that the battery does not become discharged.
7.7 Licensing
A government license is usually required to operate this radio on the air.
7.8 Radio Service
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. Contact your system operator for service.
If no characters or all characters appear in the display, the viewing angle may be
improperly adjusted. Refer to
Section 3.3 for more information.
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 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 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.
