CTCSS Scan Operation

1.Press [SCAN] to start scanning (GS or OS) mode.

2.Press and hold [CTCSS] to change to CTCSS scan mode.

3.During scanning and a signal is sensed on a CTCSS CH, the UH-052XRstops 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.
