10ADVANCED OPERATIONSTIME -OUT TIMER (TOT)The purpose of the Time-out Timer is to prevent any caller from using a channelfor an extended period of time. If you continuously transmit for a period of timethat exceeds the programmed time, the transceiver will stop transmitting and analert tone will sound. To stop the tone, release the PTT switch.Your dealer can program a warning function to alert you before the TOT expires.Continuously transmitting for the time specified by your dealer will cause thewarning tone to sound.B USY CHANNEL LOCKOUT (BCL)The Busy Channel Lockout feature is activated or deactivated by your dealer.When activated, BCL prevents you from interfering with other parties who may beusing the same channel that you selected. Pressing the PTT switch while thechannel is in use will cause your transceiver to emit an alert tone andtransmission will be inhibited (you cannot transmit). Release the PTT switch tostop the tone and return to receive mode.TALK A ROUNDYou may occasionally experience an interruption in service (due to a powerfailure, etc.). During such an occurrence, you can continue communication byusing the Talk Around feature, if it has been programmed by your dealer.Talk Around allows you to communicate directly with other transceivers, withoutthe use of a repeater. However, if the station you want to contact is too far away,or there are geographical obstacles in the way, you may not be able to contactthe station.Toggle Talk Around ON and OFF by pressing the key programmed as Talk Around.ï The indicator corresponding to the Talk Around key lights while the Talk Around function is ON.ï When using Talk Around, the ìreceiveî frequency is used for both transmission andreception, and the QT/DQT ìdecodeî signalling is used for both encoding and decoding.M ONITORPress the key programmed as Monitor to turn the transceiver signalling OFF.While signalling is OFF, you can hear all signals received on your currentchannel. With signalling ON, you can hear only signals that match the signallingprogrammed in your transceiver. Press the Monitor key again to return tonormal operation.Press and hold the key programmed as Monitor for 2 seconds to listen to weaksignals that you cannot hear during normal operation, and to adjust the volumewhen no signals are present on your selected channel. Press the Monitor keyagain to return to normal operation.
