STOPPING SCAN
When switching to channel 1-15, the radio will stop scanning.
Introduction:
1. Dealer can set the following two ways to restart scanning after its
pause:
1) Time-control
The radio will restart scanning after pausing for some time while
receiving signals. The pausing time can be preset from 0.5 to 5
seconds.
2) Carrier wave control
The radio will pause scanning after receiving signals and will
restart scanning 3 seconds after the signal disappears.
2. The working channel of the radio will respond to the following
channels automatically when pressing PTT button during scanning.
The dealer can select one among the following six ways.
1) Last called
When pressing PTT button, the radio will transmit from the last
channel that received a call.
2) Last used + currently working channel
When pressing PTT button during the scanning, the radio will
transmit from the last channel that received a call. When pressing
PTT button during the scanning pause, the radio will transmit from the
currently working channel.
3) Selected channel
When pressing PTT button, the radio will transmit from the first
channel of the scanning list.
4) Selected channel + currently working channel
When pressing PTT button during scanning, the radio will always
transmit from the first channel in the scanning list. When pressing
PTT button during the scanning pause, the radio will always transmit
from the currently working channel.
5) Priority channel
SCAN FUNCTION

AUXILIARY FUNCTIONS

The radio will transmit signals from the priority channel in the scan
list when pressing PTT button.
6) Priority channel + currently working channel
When pressing PTT button during scanning, the radio will always
transmit from the priority channel. When pressing PTT button during
the scanning pause, the radio will transmit from the currently working
channel.
Note:
Currently working channel means the channel in which the radio
holds on under the following four conditions.
1) After receiving the signals, the radio will still stay in the current
channel before restarting the scan.
2) When receiving signals during scanning, the radio will pause on
the current channel and will keep staying on it for 3 seconds after the
signals disappear.
3) Radio will stay on the current channel when pressing PTT during
scanning.
4) When the radio transmitting ends by releasing PTT button, within
the transmitting pause time preset by the local dealer, the radio will
stay in the current channel.
Selected channel: The first channel in the scanning list set by the
dealer.
Priority channel: The prior channel in the scanning list set by the
dealer.
Only when priority channel has been selected, the options of /
priority channel 0and /priority channel + currently working channel 0
in Revert Channel are available.
TIME-OUT TIMER
Time-out timer can prevent the user from continuously talking
overlong and prevent the radio body heating due to continuous
longtime transmitting.
If you continuously transmit longer than the time limit preset by the
dealer, the radio will stop transmitting and warning tone sounds, and
to stop the warning tone please release the PTT button. Pressing the
PTT button again will resume transmitting.
BATTERY SAVING
The automatic battery saving function decreases the power
consumption when no signal is received and no operation is
conducted.
If the battery saving function is activated, 10 seconds after the radio
doesn't receive any signals or no operation is being conducted, the
radio enters battery saving mode. When a signal is received or any
operation occurs, it exits battery saving mode automatically.
LOW BATTERY WARNING
When the battery power goes below a certain value in transmitting,
LED flashes red and Low battery warning tone sounds and then the
radio stop transmitting. You need to recharge or change the battery.
MONITOR

Monitor Lock: Press the monitor button once to deactivate the
signaling, and squelch un-mutes. Press it again to return to normal
operation and squelch mutes.
SQ Off: When there is no signal received, the squelch circuit of the
radio will automatically mute the speaker, so you will not hear the
background noise. Press the MONI key to force the squelch un-mute.
CTCSS/DCS
CTCSS/DCS tones may have been pre-programmed on some
channels. A CTCSS/DCS tone is a sub-audible tone, which allows you
to ignore (not hear) calls from other parties who are using the same
channel. The dealer can set CTCSS/DCS tones on radio channels.
When you receive a signal that has a tone different from the one set
on your radio, you will not hear the signal. Likewise, signals that you
transmit will only be received by the 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.
Voice Annunciation of Current Channel Number
If voice annunciation of current channel number has been activated,
when pressing the channel annunciation button in stand-by mode, the
current channel number will be annunciated in the preset language
through the loudspeaker. If turn on the radio with this button pressed,
the annunciation language will be changed. Repeat turning on the
power with this button pressed, the type of the annunciation language
can be changed in sequence “ Chinese Male---English Male---
Chinese Female---English Female---No Annunciation” .
Wired Clone
If wire clone function has been activated, after entering wire clone
mode, the radio will not exit the wire clone mode automatically. You
have to turn on the radio again to enter the user mode. The operating
procedure is as follows:
1) Press MONI key to turn on the radio. About two seconds later
the red light flashes twice and two beeps sound, and then the radio
enters the wire clone mode.
2) Press PTT button, and slave radio that is to be sent with
cloning data will be in the Open/Prohibition wire clone mode.
However, the wire clone setting on the master radio will not change.
Press PTT button. If the green light flashes twice and one beep
sounds it is in the Open state; if the red light flashes twice and two
beeps sound it is in the Prohibition state.
When entering wire clone mode, the default setting on the slave
cloned radio is wire clone prohibition.
3) Press MONI key, the red light flashes and cloning begins.
When cloning is finished, red light turns dim.
Note:
To activate Open/Prohibition Wire Clone mode, short circuit the two
points of SELF to switch on the current and enter model setting
mode, the manually adjustment and wire clone functions are
activated automatically; then to prohibit wire clone function, press
MONI key.
You can also open or prohibit the wire clone mode by PC
programming software.
Once the wire clone function is prohibited, the radio cannot enter wire
clone mode. Wire clone prohibition is set as the default when the
radio leaves factory.
