3 BASIC OPERATION Receiving and transmitting Receiving: qqRotate [VOL] to turn ON the power. wwSelect a channel. ➥➥Rotate [ROTARY SELECTOR]. ➥➥Push one of the memory channel keys, [MR-CH 1] to [MR-CH 4]. eeWhen receiving a call, adjust the audio output to a comfortable listening level. NOTE: When a matched RX code signal is received, the transceiver automatically transmits its microphone audio for a specified time period, depending on the presetting. Transmitting: CAUTION: Transmitting without an antenna will damage the transceiver. See page 1-3 for antenna attachment. Wait for the channel to become clear to avoid interference. qqWhile holding down [PTT], speak into the micro- phone at a normal voice level. wwRelease [PTT] to receive. NOTE: To maximize the readability of your signal: 1. Pause briefly after pushing [PTT]. 2. Hold the microphone 5 to 10 cm (2 to 4 inches) from your mouth, then speak at a normal voice level. DDTransmitting notes • Transmit inhibit function The transceiver has several inhibit functions, which restrict transmission under the following conditions: - The channel is muted. (PMR operation only) - The channel is busy. - A signal with an unmatched (or matched) CTCSS (or DTCS) tone is received. - The selected channel is a 'receive only' channel. • Time-out timer After continuously transmitting longer than the preprogrammed time period, the time-out timer activates, and stops further transmitting. • Penalty timer Once the time-out timer activates, transmitting is further inhibited for a time period determined by the penalty timer. • PTTID call The transceiver automatically sends the ID code (5tone, DTMF or BIIS operations) when [PTT] is pushed (beginning of the transmission) and/or released (end of transmission), depending on the presetting. 3-5
