Battery Charging

1. Take out the charger, plug the AC（100-240V）50/60Hz, then Green
LED flashes;

2. Plug the battery or the radio with battery on the charger; make sure
the battery is connected with the charger.

3. The charging process initiates when the red LED lights, the charging
time based on the battery capacity. The green LED lights indicating
the battery is fully charged.

4. Use the USB cable to plug to the radio, red LED lights when charging,
green LED lights when fully charged.

Function Operation

SWITCHING POWER ON/OFF

Turn the power switches/volume control clockwise. You will hear a
channel number, indicating the radio is ON.

ADJUSTING THE VOLUME

Hold MONI button down to listen to audio level while rotating the Power
switch/Volume control. Rotate clockwise to increase volume and
counterclockwise to decrease volume.

SELECTING THE CHANNEL

Turn the channel switch to select your desired channel. NO.16 is
Scanning Channel

PTT TRANSMIT

To transmit, press and hold [PTT] and speak into the microphone in your
normal tone of voice.

Note: The radio outlook based on the real radio.

A. LED Indicator: Green LED flashes when receive the signal, Red LED
flashes when transmission.
B. Channel knob: Rotate the knob to choose the channel (CH1-CH15),
CH16 is scan channel.
C. ON/OFF knob/Volume knob: Rotate the knob clockwise to turn on the
radio, anticlockwise to turn off the radio. By rotating to control the volume.
D. PTT switch: Press PTT and speak to the microphone to call, listen
when release.
E. Monitor: When press Monitor key, the squelch opened and the
background noise comes out; the squelch close when release the
monitor key.
F. USB Rapid charge plug.
G. Speaker/Microphone rubber plug: Please cover when not use the
speaker and microphone.
H. Insert loudspeaker. J. Microphone

SQUELCH LEVEL

The purpose of Squelch is to mute the speaker when no signals are
present (Squelch OFF). With the squelch level correctly set, you will hear
sound only while actually receiving signals (Squelch ON). The squelch
level can be adjusted via program software.
The frequency of squelch is 0 (on) -9 (deep), steps: 1.

SCANNING SWITCH

When walkie-talkie is set as scan via software, turn the channel selector
to channel 16, the radio will automatically detect the activity of scanning
channel from CH1 to CH15 channel (each channel can bet set scan or
not via software) , When the signal is scanned channel, the radio will
automatically stop on the channel for the call.
a. Walkie-talkie will stay on the signal channel, when the signal
disappears and then after 15s, continue scanning the next channel.
b. If there are less than 2 channels, it cannot scan.
c. On channel 16, press and hold the PTT and MONI key, it will turn on
the SCAN or turn off the SCAN.

VOX

a. VOX function is effective when the function is turn on.
b. VOX gain level: When the sound level is higher than the set level of
VOX, VOX automatically transmit. The VOX gain level can adjust from
1 to 9 levels.
c. When a signal is received, VOX will not transmit even if the sound
level is higher than the set VOX gain level.

d. On channels CH1 ~ CH5, press and hold the PTT and MONI, then
switch on the radio, thus to activate the VOX function ON/OFF.

MONITOR

When you are receiving and no signals present, the squelch function can
mute the speaker, so you cannot hear the background noise .If you want
to switch the squelch function OFF, press and hold MONI button .It is
very helpful when you want to adjust the volume level and receive the
week signals.

Battery Saving

a.ON: Entering into the battery saving state automatically without any
operation for 10 seconds
b.OFF: Battery saving is off.

Busy Channel Lockout (BCL)

Switch on or off each effective channel busy lockout function via PC
programming software. When open this setting, signal from the current
channel is banned to transmit.

Beep

a. The beep is on, and the "Di" sounds is emitted for every rotation of the
channel
b. The beep is off, and no "Di" sounds for every rotation of the channel

Low Battery Voltage Warning

When the voltage is lower than the present value, a prompt "Please
change battery" is issued every 5 seconds, press the PTT buttons is
invalid and make "Di" sounds.

Chinese / English Prompt

This radio includes Chinese and English two kinds of voice signal mode
(channel knob must be switched to channel CH15), firstly turn off the
radio, and then hold the PTT button and MONI button while turning on
the power to convert another way. Each time you switch a way so
repeated.

Time-out timer (TOT)

The function of the time-out timer is to prevent the speaker from using a
channel too long and continuously, and the interphone emits
continuously too long and the body heats up. If you continuously transmit
the interphone, the TOT limit time set by the machine is exceeded; the
radio will stop transmitting (the time can be programmed by computer
while the factory setting time is 1 minute). Release the PTT button and
press PTT again to resume transmitting.

QT / DQT

The radio’ s QT/DQT for each channel can be program by software.
When the channel set the QT/DQT, the radio squelch open only if it
receives a signal that uses the same QT or DQT. The radio squelch does
not turn on if the same channel uses different QT / DQT calls, only lights
in green, sub-CTCSS 50 groups, and digital sub-audio DCS 105 groups.

Note: Although using a channel with CTCSS / DCS sub-audio may be

preferable to receiving unwanted calls, it does not mean your call is a
secret.
