Selecting the Channel

Your radio has 22 channels plus 8 repeater channels. The channel is the frequency the radio uses to transmit. Channels 8-14 are FRS

0.5watt only and all other channels are GMRS. (See the

“Channels and Frequencies” tables on overleaf for details.)

watt channel, displays. When the radio is on a 1.5 watts

channel, displays. The current channel flashes.

2.Press or and select an unused or quiet channel.

3.Press to save the channel setting or to continue set up.

The 8 repeater channels are disabled by default. See ”Enabling Repeater Channels” on overleaf for information on setting the

radio to a repeater channel.

Selecting the Interference Eliminator Code

Interference Eliminator Codes help minimize interference by blocking transmissions from unknown sources. Your radio has 121 Interference Eliminator Codes. Codes 1 – 38 are analog tones. Codes 39 – 121 are digital codes. 0 is the off position, no analog or digital codes are enabled.

To set the code for a channel:

1.Press until the code starts to flash.

2.Press or to select the code.

3.Press to save the code setting or to continue set up.

You can set a different code for each channel using this procedure. An extended press of or allows you to scroll through the Interference Code rapidly so you can quickly reach the code you want.

When setting codes for repeater channels 15R-22R, this code

value is only used for receiving. The transmitted code can be set separately for repeater access. See ”Selecting the Repeater Access (TX) Code” on overleaf for additional

information.

Note: You must set the Interference Eliminator Code to 0 to communicate with radios that do not have Interference Eliminator Codes.

Setting and Transmitting Call Tones

Your radio can transmit different call tones to other radios in your group so you can alert them that you want to talk. Your radio has 10 call tones from which to choose, including 5 animal sounds and 5 regular call tones.
