Call Procedure; Receiving And Transmitting - Icom iC-F3161DT Instruction Manual

■ Call procedure

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 15 or 16 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.
