If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center. POSSIBLE CAUSE • Power connector has a poor contact. • Polarity of the power connection is reversed. • Blown fuse. SOLUTION REF. • Check the connector pins. • Reconnect the power cable observing the proper polarity. Replace the fuse, if damaged.
IC-2710H.qxd 02.2.8 16:55 Page 76 (1,1) MAINTENANCE PROBLEM SOLUTION REF. p. 16 • The microphone keypad lock function is activated. • Priority watch is paused on the watching frequency. • Push and hold [(VFO)LOCK] to deactivate the frequency lock function. • Push [FUNC], then [A16KEY LOCK] to deactivate the microphone keypad lock function. • Push the selected band’s [(M/CALL)PRIO] to resume the watch.
