Choosing a Channel and CTCSS
Your radio has 14 channels and a Continuous Tone Coded Squelch System (CTCSS) that you can use to talk to others. You can only communicate with radios that are set on the same channel and CTCSS tone code. A CTCSS tone is subaudible and selectable from the 38 standard tone frequencies. You must select the same channel as your party selected.
To choose a channel for the FRS500:
Press the up or down button repeatedly to select one of the 14 channels.
(The number on the LCD changes to indicate that a new channel has been selected.)
The BUSY icon and 
icon appear while receiving a transmission.
To choose a CTCSS code for the FRS500:
You may want to hear calls from specific persons in your group. The CTCSS code that you enter allows you to block other calls and only receive from those who are using the same channel and CTCSS code.
This feature does not cause your conversation to be private. Anyone else on the channel will be able to listen. It only relieves you of listening to unwanted conversations.
