102 BASIC OPERATIOND Transmitting notes• Transmit inhibit functionThe transceiver has several inhibit functions which restricttransmission under the following conditions:- The channel is in mute condition (‘Inaudible’ condition;“ ” does not appear.)- The channel is busy.- Un-matched (or matched) CTCSS is received.(Depending on the pre-setting.)- The selected channel is a ‘receive only’ channel.• Time-out timerAfter continuous transmission for the pre-programmed timeperiod, the time-out timer is activated, causing the transceiv-er to stop transmitting.• Penalty timerOnce the time-out timer is activated, transmission is furtherinhibited for a period determined by the penalty timer.D TX code channel selectionIf the transceiver has [TX Code CH Select] assigned to it, theindication can be toggled between the operating channelnumber (or name) and TX code channel number (or name).When the TX code channel number (or name) is displayed,[CH Up]/[CH Down] selects the TX code channel.USING [TX CODE CH SELECT] KEY:q Push [TX Code CH Select]— a TX code channel number(or name) appears.w Push [CH Up] or [CH Down], or rotate [CH Up/Down] toselect the desired TX code channel.e Push [Call] (or [PTT] during BIIS operation) to transmit theselected TX code.USING [TX CODE CH UP]/[TX CODE CH DOWN] KEY:If the transceiver has a [TX Code CH Up], [TX Code CHDown] or [TX Code CH Up/Down] key assignment, the pro-grammed TX code channel can be selected directly whenpushed or rotated.NOTE for PMR or BIIS PMR operation:• The LCD indication does not change when the operatingchannel number (or name) is displayed. (Depending onthe pre-setting)• To check the selected TX code, push [TX Code CHSelect].
