same channel. When you receive a signal that has a
tone different from the one set on your radio, you will
no t hear the si gn al . Likewise, s ig nals that you
transmit will only be received by parties whose
CTCSS/DCS tones are the same as yours.
Note:
* Using a CTCSS/DCS channel doesn't mean your
calls are private. If other parties' CTCSS/DCS tones
are identical with yours, they can hear your calls.
* Set the battery saving mode to be “O f f” or “1:1” if
the CTCSS/DCS decoding time is long.

b) Priority Scan:
One channel in the scan list can be set as the
priority channel, which enables it to have the highest
priority during scanning. The radio will scan a non-
priority channel firstly, then the priority channel, and
then the next non-priority channel, and then the
priority channel again, and the scan goes on like this.
If the priority channel and the “lookback time” have
been set for the scan list, when the radio is receiving
signals on a non-priority channel, and the scanning is
paused, the radio will check the priority channel at the
preset intervals. If there are signals in the priority
channel, it will stay at the priority channel; if there is
no signal, it will return to the original channel.
c) The revert channel (Tx channel) during the scan
can be designated by the dealer. There are following
options available:
Selected Channel: When pressing the PTT button,
the radio will transmit from the first channel of the
scan list.
