CTCSS Scan Operation
1. Press
[SCAN]
to start scanning (GS or OS) mode.
2. During scanning if a signal is sensed on a CTCSS CH, the
UH-042XR
stops for about 400msecs (decode time) to decode the CTCSS
code. If there is no code or the receive code does not match the one
programmed on the unit, the unit resumes scanning.
On the example below only radio 1 and 9 can communicate or hear each other
because they are using the same or common CTCSS code.
