3 BASIC OPERATION ■■Call procedure ■■Receiving and transmitting When your system employs tone signaling, excluding CTCSS and DTCS, this call procedure may be necessary prior to voice transmission. The tone signaling employed may be a selective calling system which allows you to call only specific station(s) and prevents unwanted stations from contacting you. q Select the desired TX code channel or 2/5-tone code according to your System operator's instructions. • This may not be necessary, depending on the presetting. • Refer to pages 14 or 15 for selection. w Push [Call], assigned to one of the dealer programmable keys. e After transmitting, the remainder of your communication can be carried out in the normal way. Selective calling Non-selective calling CAUTION: Transmitting without an antenna will damage the transceiver. Receiving: q Rotate [VOL] to turn ON the power. w P ush [CH Up] or [CH Down], or rotate [ROTARY SELEC- TOR], depending on the presetting, to sequentially select the conventional system channel. e W hen receiving a call, adjust the audio output level to a comfortable listening level.
