■

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 ac-

cording 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.

■

 

 CAUTION: Transmitting without an antenna will damage 
the transceiver. 

Receiving:
q

 Rotate [VOL] to turn ON the power.

w

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

TOR], depending on the presetting, to sequentially select 
the conventional system channel.

e

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

comfortable listening level.
NOTE: When a matched RX code signal is received, audio 
from the microphone may be automatically transmitted for 
a specified time period.*

* Depending on the presetting. Ask your dealer for details.

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

  While holding down [PTT], speak into the microphone at a 

normal voice level.

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

scribed on the previous page may be necessary.

w

 Release [PTT] to receive.

  

IMPORTANT: To maximize the audio quality of your sig-
nal:

 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.
