other users on the same channel.

Programming CTCSS Code

1. Select a desired channel to be used with CTCSS.
2. Press and hold             for 1.5 secs. CTCSS icon blinks.
3. Press           or           to select the desired CTCSS code.
4. Press             to save the selected code. CTCSS icon stops blinking.

The uh073sx will return to standby mode after 10 secs. of no 
activity. CTCSS code can be programmed on every channel. There 
are 38 available CTCSS tone per channel.

CTCSS Scan Operation

1. Press             to start scanning (GS or OS) mode.
2. Press and hold            to change to CTCSS scan mode.
3. When a signal is sensed on a CTCSS CH, the uh073sx stops for about 400
msecs (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.

Channels 5 and 35 are used for emergency channels. CTCSS will 
not operate on these channels.
