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.
