Analog channels programmed with a receive code guard will be heard only when the 

proper carrier frequency and Code Guard value is received. When the transceiver 

is in monitor mode, analog and mixed mode receive channels will also unmute even 

without the proper Code Guard being received.

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.)
The frequency must be clear prior to transmitting on a Code Guarded channel. If 

the LED Indicator is blinking green do not transmit. Busy Channel Lockout can be 

programmed to disallow transmitting while a channel is busy.

Press the PTT switch.

When the transmitter is on, the LED Indicator glows red and TX appears in 

the display.
