BASIC OPERATION

■ Call procedure

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 specific station(s) only
and prevent 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 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.
