Transceiver Service

If your transceiver is not operating properly, “OUT-LOCK” or

“PROG ERR” may be displayed. To attempt to clear this condition, turn power off and then on again to reset the control logic. Another indication that could be displayed is “NO POWER”. This indicates that transmitter temperature or supply voltage may be excessive. Release the PTT switch and allow the transceiver to cool, and make sure that the vehicle battery voltage is within the normal range.

Also make sure that the controls are properly set and that the power, external speaker (if used), and accessory (if used), cables are securely plugged into the back of the transceiver. If the transceiver is completely inoperative, check the power cable fuse. 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.

NOTE: There are no user-serviceable components in the transceiver. Altering internal adjustments can cause illegal emissions, void the warranty, and result in improper operation that can seriously damage the transceiver.
