24BACKGROUND 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 time that exceeds the programmed timeset by your dealer (default is 1 minute), the transceiver will stop transmitting and analert tone will sound. To stop the tone, release the microphone PTT switch.Your dealer can program the TOT time in the range of 15 seconds to 20 minutes.BUSY CHANNEL LOCKOUT (BCL)When activated, BCL prevents you from interfering with other parties who may beusing the same channel that you selected. Pressing the microphone PTT switchwhile the channel 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.If activated, you can override this function. To override BCL, press themicrophone PTT switch again immediately after releasing it (within half a second).Note: Ask your dealer for an explanation on how BCL functions when using QT, DQT, DTMF,5-tone, or FleetSync signaling.SIGNAL STRENGTH INDICATORThe signal strength indicator displays the strength of received calls:Strong signalMedium signalWeak signalVery weak signalBEGINNING/ END OF TRANSMIT SIGNALThe Beginning of Transmit and End of Transmit identification signals are used toaccess and release some repeaters.If Beginning of Transmit is set, the ID signal is transmitted when you press themicrophone PTT switch.If End of Transmit is set, the ID signal is transmitted when you release themicrophone PTT switch.If both are set, the ID signal is transmitted when you press and release themicrophone PTT switch.
