PTT Programming a Radio Channel
Four valid digits must be entered for the radio to
accept PTT programming. The first two digits entered
are the frequency code from Table 1, followed by the
two digits for the QC code from Table 2.
1. Place the radio in Program / Readout mode as
described in Fig-3 on page 11.
2. Press the Channel Selector button to select the
radio channel you would like to program.
3. Enter the first digit by pressing the PTT button
the number of times equal to the digit’s value.
4. Pause after the digit is entered, a low tone will
sound indicating that the digit has been
accepted.
5. Enter the second, third and fourth digits using the
same method as the first digit.
6. Press the Volume Up button to enter the new
channel programming. The radio will emit a triple
beep confirmation tone to indicate that
programming has been accepted.
7. To program another channel, follow steps 2
through 6.
8. Turn the radio off and then on again – the radio
is now ready for use.
Notes:
1. To enter the digit zero ( 0 ), press the PTT ten
times.
2. Program “44” to enter “No Code” for Quiet Call.
You must enter “44” to match radios not having
tone codes.
3. An error tone will sound if you attempt to save an
incorrect digit. Turn the radio off, check the
digits you are attempting to enter, then start over
again.
4. If you make a PTT click error, turn the radio off
then on, and start over.
5. If the radio does not emit a confirming triple tone
when you attempt to enter Program / Readout
mode, the radio was dealer customized to
disable PTT programming.
6. Refer to the Frequency Table 1 and Tone Code
(Quiet Call

) Table 2 on page 13.
Return to Normal Operation
After you finish programming, turn the radio off and
then on again. The radio will beep when it is ready for
normal operation.
PTT Programming Mistakes
Invalid Entries
An error tone means that
you tried to save an invalid entry. No programming
changes are made in this case. A triple tone will
sound next indicating that the radio is still in
programming mode, and ready for an entry.
PTT Entry Mistakes
If you press the PTT five
times when you intended four, for example, or if you
just lose count, do not press the Volume Up button to
store the entry. Instead, start over by turning the
radio off and placing the radio in programming mode
again.
