A NOTE ABOUT THE CTCSS CODES
This radio incorporates 38 CTCSS (

that, when activated, prevent the user from hearing other radios that do not have the
same code. These codes
do not
make your conversation private. If you experience
difficulties contacting or hearing other radios in your group make sure the
CTCSS
code is set the same on all radios. If you are using the G-220 where interference from
other radios or electrical devices are present, enabling the
CTCSS
codes will usually
mute the interference. Many times interference will be noticed by the presence of loud
static from the speaker.
