Transceiver Service

If the transceiver is not operating properly, “SYN ERR” or “PROG ERR” may be displayed. It is also possible that all segments of the display are indicated when power is turned on. To attempt to clear this condition, turn the power off and then on again to reset the control logic. Also make sure that the battery is charged, the controls are properly set, and the antenna is tight. If the transceiver still does not operate properly, contact your system operator for service.

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