Interference Eliminator Code
Interference Eliminator Codes help minimize interference by providing you with a
choice of code combinations.
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.
You can set a different code for each channel using this procedure.
Note: You must set the Interference Eliminator Code to on an FRS radio that uses
Interference Eliminator Codes to communicate with other FRS radios that do
not have Interference Eliminator Codes.
