CTCSS Scan Operation

2. Press and hold

[CTCSS]

to change to CTCSS scan mode.

3. During scanning and a signal is sensed on a CTCSS CH, the

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.

➤ Built-in Voice Activated Circuit (VOX) feature enables user to

transmit automatically by speaking on the microphone of the VOX
headset (not supplied) without pressing the PTT switch.
