BASIC OPERATION

■ Call procedure

When your system employs tone signalling (excluding CTCSS
and DTCS), a call procedure may be necessary prior to voice
transmission. The tone signalling employed may be a selec-
tive 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 according to your sys-
tem operator's instructions.
• This may not be necessary, depending on the pre-programmed
settings.
• Refer to pages 14 and 15 for details.
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: Depending on the pre-programmed settings, the
transceiver automatically transmits the microphone audio
for the pre-programmed time period when a matching sig-
nal is received.
Transmitting:
Wait for the channel to become clear to avoid interference.

your normal voice level.

scribed to the left may be necessary.
w Release [PTT] to return to receive.

1. Pause briefly after pushing [PTT].
2. Hold the microphone 5 to 10 cm from your mouth, then
