■

When your system employs tone signalling (excluding 
CTCSS and DTCS), this call procedure may be necessary 
prior to voice transmission. The tone signalling employed 
may be a selective calling system which allows you to call 
specific station(s) only and prevent 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 programming.
  • 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 fashion.

■

 

 NOTE: Transmitting without an antenna may damage the 
transceiver. See (p. 1) for accessory attachments.

Receiving:
q

 Rotate [VOL] to turn the power ON.

w

  Push [CH Up] or [CH Down], or rotate [ROTARY SELEC-

TOR]* to select the conventional system channel, in se-
quence.

  *Depending on the pre-setting.

e

  When receiving a call, adjust the audio output level to a 

comfortable listening level.

Transmitting:
Wait for the channel to become clear to avoid interference.
q

  While pushing and holding [PTT], speak into the micro-

phone at a normal voice level.

  •  When a tone signalling system is used, the call procedure de-

scribed at the previous page may be necessary.

w

 Release [PTT] to return to receive.

  

IMPORTANT: To maximize the audio quality 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 into the microphone at a nor-
mal voice level.
