Code Guard/NAC Operation
Conventional Channels
Code Guard Receive
Analog channels programmed with a receive code guard will be heard
only when the proper carrier frequency and Code Guard value is
received. Analog and mixed mode receive channels will also unmute
when the radio is in monitor mode. This is also true of digital channels.
Monitor mode is carrier squelch only.
Code Guard Transmit
Whenever transmitting on an analog channel, any programmed sub-
audible Code Guard is transmitted. Depending on radio programming,
the Code Guard can be the default tone assigned to the channel or a
tone selected from the Code Guard Picklist (see Pick List Options).
Busy Channel/Transmit
Indicator
Ch 1
KNG - P25
171.58500 MHz
LITE T/A MENU LCK
TXA
The frequency must be clear prior to
transmitting on a Code Guarded channel. If the
LED Indicator is green or blinking green do not
transmit. Busy Channel Lockout can be
programmed to disallow transmitting while a
channel is busy.
1. Press the PTT switch. When the transmitter
is on, the LED Indicator glows red and TX
appears in the display.
2 Talk in a normal voice with the microphone
one to two inches from your mouth.
3. Release the PTT switch to stop transmitting.
Analog Squelch Control
Sub-audible signaling (CTCSS/CDCSS) is used to allow a group of
radios to be selectively called in an analog system. Programming the
receive code guard equal to zero allows for Carrier Squelch operation,
where the radio will unmute whenever a carrier is detected regardless
of the transmitted Code Guard.
