Tone Search Scanning
In operating situations where you don’t know the CTCSS tone being used by an-
other station, you can command the radio to listen to the incoming signal and scan in
search of the tone being used.
To scan for the CTCSS tone in use:
1. Press the key momentarily, then rotate the knob, as needed, until Op-
erating Function Row 12
[
TCH, DCH
]
appears on the display.
2. Press the
(
TCH
)
key to activate CTCSS Encoder/Decoder; (the “ ”
icon will appear on the display) and start scanning for the incoming CTCSS
tone.
3. When the radio detects the correct tone, it will halt on that tone, and audio will be
allowed to pass.
4. Press and hold in the
(
TCH
)
key for one second; the CTCSS tone detected
will be stored as the “current” tone, so it may be used for memory storage pur-
poses, and you may now exit to normal operation.
