BASIC OPERATION 2 D Transmitting notes D TX code channel selection 1 • Transmit inhibit function T he transceiver has several inhibit functions which restrict If the transceiver has [TX Code CH Select] assigned to it, the indication can be toggled between the operating channel 2 transmission under the following conditions: number (or name) and TX code channel number (or name). 3 - The channel is in mute condition ('Inaudible' condition; When the TX code channel number (or name) is displayed, " " (Audible indicator) is not displayed.) [CH Up] or [CH Down] selects the TX code channel. 4 - The channel is busy. - Un-matched (or matched) CTCSS is received. (Depending on the presetting) 5 USING [TX CODE CH SELECT] KEY: q P ush [TX Code CH Select]- a TX code channel number 6 - The selected channel is a 'receive only' channel. (or name) is displayed. w P ush [CH Up] or [CH Down] to select the desired TX code 7 • Time-out timer channel. 8 A fter continuous transmission for the pre-programmed period of time, the time-out timer is activated, causing the e After selecting, push [TX Code CH Select] to set. • Return to the stand-by mode. 9 transceiver to stop transmitting. r Push [Call] to transmit the selected TX code. 10 • Penalty timer USING [TX CODE CH UP]/[TX CODE CH DOWN] KEY: 11 O nce the time-out timer is activated, transmission is further If the transceiver has a [TX Code CH Up] or [TX Code CH 12 inhibited for a period determined by the penalty timer. Down] key assignment, the programmed TX code channel can be selected directly when pushed. 13 • PTTID call 14 T he transceiver sends the ID code (5-Tone, DTMF or digital ANI) automatically when [PTT] is pushed (beginning of 15 the transmission) and/or released (end of transmission) 16 depending on the setting. P  TTID can be also used with the MDC 1200 signaling system. (p. 13) 9
