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 FRS550W:
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.)
To choose a CTCSS code for the FRS550W:
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.
The BUSY icon and icon appear while receiving a transmission.
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.
