BASIC OPERATION
■ Call procedure
When your system employs tone signaling (excluding CTCSS
and DTCS), the 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, 2/5-tone code,
Individual ID code* or Talkgroup ID code* according to
your System Operator’s instructions.
• This may not be necessary depending on programming.
• Refer to pgs. 11–13 for selection.
*Digital mode operation only.
w Push the call key (assigned to one of the dealer program-
mable keys; except for the Digital mode operation) or [PTT].
e After transmitting, the remainder of your communication
can be carried out in the normal fashion.
■ Receiving and transmitting

q Push [ ] to turn the power ON.
w Push [CH Up] or [CH Down], or rotate [CH Up/Down] to
select a channel, in sequence.
e When receiving a call, adjust the audio output level to a

q Take the microphone off hook.
• 2-tone, 5-tone mute may be released. (The ‘audible’ condition is
