Call procedure
When your system employs tone signalling (excluding CTCSS and
DTCS), the call procedure may be necessary prior to voice trans-
mission. 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 5-tone code according to
your System Operator’s instructions.
• This may not be necessary depending on programming.
• Refer to the next page for selection.
w Push the call switch (assigned to one of the dealer programma-
ble switches: [P0], [P1], [P2], [P3], [S1] and [S2]).
e After transmitting a 5-tone code, the remainder of your commu-
nication can be carried out in the normal fashion.

Tx code channel selection
Your radio may be programmed for Tx code channel selection. In
this case, you can choose a Tx code channel to be transmitted
when using the call function (p. 7).
Push the Tx code channel switch (assigned to one of the dealer-
programmable switches) to activate the function, then enter digits
via the keypad to select the desired Tx code channel.
• The selected code channel (containing a pre-programmed 5-tone
code) is transmitted when using the call function.
‘‘
Manual 5-tone codes
Depending on programming, you may be able to send 5-tone codes
manually.
Push the Tx code switch to activate the function, then enter the de-
sired transmit code (up to 7 digits) using the keypad.
• Activate the call function to transmit the 5-tone code.
