2 BASIC OPERATION ■ Receiving and transmitting (Continued) D Transmitting notes • Transmit inhibit function The transceiver has several inhibit functions which restrict transmission under the following conditions: - The channel is in the 'Inaudible' (mute) mode; " " (Audible icon) does not appear. - The channel is busy. However, depending on the prepro- grammed settings, you can transmit when the call includes an unmatching (or matching) CTCSS (DTCS), RAN code, or Individual or Talkgroup ID. - The selected channel is a 'receive only' channel. • Time-out timer If continuous transmission exceeds the pre-programmed time-out timer limit, the transmission is cut off. • Penalty timer After the transmission is cut off by the time-out timer, transmission is further inhibited for the pre-programmed penalty timer period. • PTTID call The transceiver automatically sends the 5-tone, DTMF, BIIS or digital ANI ID code when [PTT] is pushed (at the beginning of the transmission), and/or when it is released (at the end of transmission), depending on the preprogramming. A PTTID call also be made with the MDC 1200 signaling system. D TX code channel selection If the transceiver has a key assigned to [TX Code CH Select], the display can be toggled between the operating channel number (or name) and TX code channel number (or name). When the TX code channel number (or name) is displayed, [CH Up] or [CH Down] selects the TX code channel. USING [TX CODE CH SELECT] KEY: q P ush [TX Code CH Select]- a TX code channel number (or name) appears. w P ush [CH Up] or [CH Down] to select the desired TX code channel. e After selecting, push [TX Code CH Select] to set. • Return to the stand-by mode. r Push [Call] to transmit the selected TX code. USING [TX CODE CH UP]/[TX CODE CH DOWN] KEY: If the transceiver has a key assigned to [TX Code CH Up] or [TX Code CH Down], the programmed TX code channel can be directly selected when pushed. 10
