TK-314837Panel Test Mode■ Test mode operating featuresThis transceiver has a test mode. To enter test mode,press [A] key and turn power on. Hold [A] key until testchannel No. and test signaling No. appears on LCD. Testmode can be inhibited by programming. To exit test mode,switch the power on again. The following functions areavailable in test mode.• ControlsControls “FCN” appears “FCN” not appears[Side 1] Release FCN Monitor ON and OFF[Side 2] Lamp ON/OFF Wide/Narrow[S] FFSK 1200bps and 2400bps Sets to the Tuning mode[A] Release FCN FCN ON[B] Compander function ON and OFF RF power HIGH and LOW[C] Beat shift ON and OFF Changes signaling[ENCODER] Release FCN Changes channel• LCD indicator“SCN” Unused“ ” Lights at Compander ON.“LO” Lights at RF Power Low.“P” Unused“MON” Lights at moniter ON.“SVC” Unlock“ ” Lights at FFSK 2400bps.“W” Wide/Narrow• LED indicatorRed LED Lights during transmission.
