CODE SQUELCH (ID CODE)
Code Squelch is enabled or disabled by your dealer. This function turns the
transceiver squelch OFF only when it receives the DTMF ID code that has been
set up in your transceiver. Transceivers that do not transmit the correct code will
not be heard. Consequently, you can communicate with a specific party without
listening to other parties using the same channel.
Your dealer may also activate Group Call for your transceiver. This is useful
when you want to send information to a number of units in a fleet. Ask your
dealer for details.
Note: Code Squelch cannot be used on this transceiver if Selective Call {page 18} or DTMF Number
Display {page 23} have been programmed.
RECEIVING
When you receive a signal containing the correct ID code, the squelch opens
and you will hear the call.
• The icon appears on the display and blinks.
• The TX/RX indicator flashes orange.
•To mute the speaker after the squelch opens, press the key programmed as Monitor.
•Your dealer can program the transceiver to mute the speaker after a specified time
period elapses.
• If Transpond is programmed, an acknowledgment signal is returned to the calling
station. Transpond does not function when you are called with a Group code.
Transpond can send an alert tone, a transceiver ID code, or autodial memory location
number 1 (refer to “S
TORING DTMF NUMBERS” on page 14).
• If Call Alert is programmed, an alert tone will sound when the correct ID code is
received.

2 Enter the ID code of the transceiver you want to call or enter a Group code on
the microphone keypad.
3 Use the transceiver the same as in a regular call; press the PTT switch to
transmit and release it to receive.

• When you release the PTT switch, the squelch opens. If no signal is received for a
pre-determined time, the speaker will mute.
• Pressing the key programmed as Monitor at any time will mute the speaker.
