Electromagnetic Interference
Nearly every electronic device is susceptible to electromagnetic interference (EMI)
if inadequately shielded, designed, or otherwise configured for electromagnetic
compatibility. Turn off your radio in any facility where posted notices instruct you
to do so. These facilities may include hospitals or health care facilities that may be
using equipment that is sensitive to external RF energy.
When instructed to do so, turn off your radios when on board an aircraft. Any use
of a RF device must be in accordance with applicable laws, requlations and
airline crew instructions.
Some radios may interfere with some hearing aids. In the event of such
interference, you may want to consult your hearing aid manufacturer or
physician to discuss alternatives.
If you use any other personal medical device, consult the manufacturer of your
deivce to determine if it is adequately shielded from RF energy. Your doctor or
physician may be able to assist you in obtaining this information.

In VOX mode, your radio can be used “hands-free," automatically transmitting
when you speak. You can set the VOX sensitivity level to fit the volume of your voice
and avoid transmissions triggered by background noise.
It is highly recommended to use the (Easy Pairing on page 13) function to comm-
unicate with other brands of radios, which is simple and fast.
The following is the code correspondence method, which may be slightly
complicated.
Example: Radio A is channel 22, 99 privacy codes
The CTCSS code (1-38) of the G-U1 radio corresponds to the code (1-38) of radio A.
The DCS code (1-61) of the G-U1 radio corresponds to the code (39-99) of radio A.
If the G-U1 radio is DCS code 01, the code of radio A needs to be set to 39.
The calculation method is: DCS code number + 38 = the code of radio A. 1+38=39.
The VOX sensitivity level is displayed as numbers 1-9, where number 9 is the most
sensitive level and number 1 is the least sensitive level.
Voice Activated Transmit （VOX)
OF: Turn off VOX mode.
1-9: Turn on VOX mode and set the VOX sensitivity.
Among them, level 4 is the most energy-efficient, and it is recommended to set the
power-saving level to 3. Please set the power saving level as needed, excessively
high power saving levels may cause some voice loss.
OF: Turn off power-saving mode.
1-4: Turn on power-saving mode and set the power-saving level.

Common Problems and Solutions
As the battery power decreases, the transmission power will decrease, affect-
ing the communication distance. Please keep the radio fully charged.
There are too many obstacles between the two radios, such as walls/trees/
mountains, etc., which will seriously hinder the transmission of radio signals.
The radio is set to low power, or on a channel that is restricted to low power by
the FCC. Please set the radio to high power (H) or change the channel.
Radio interference will also affect the communication distance.
1. Reasons that affect the communication distance of the radio.
2. If the radio cannot be charged, please try the following methods
to solve it.
3. Two G-U1 radios cannot communicate.
a.
b.
c.
d.
Check whether the power cord of the charging base is connected properly.
Check whether the radio is placed properly.
Check whether there are foreign objects on the charging contact points of the
radio and the contact points of the desktop charger.
Please use the original power cord for charging. Some other brands of Type-C
power cords may not be able to charge.
Use a screwdriver to remove the battery cover and reconnect the battery cable.
a.
b.
c.
d.
e.
Please check whether the channels and privacy codes of the two radios are the
same. Please note that the type of privacy code must also be the same.
Is the volume set too low so that it cannot be heard? Please turn the knob to
increase the volume.
If both G-U1s are on channel 61, channel 61 may not be able to communicate
because it is a covered frequency. Please switch to another channel.
a.
b.
c.
4. How to communicate with two-way radios of other brands.
5. Can I keep charging it on the desktop charger?
Use [Easy Pairing] to communicate. Almost all FRS and GMRS two-way radios
can be paired. (Recommended)
Set the channel and code to the same to communicate. Since the frequency
distribution of each brand may be different, it may only be applicable to some
brands.
Of course, but it is generally not recommended to charge it all the time. Charging
it all the time may reduce the life of the battery. It is recommended to charge it as
you use it, just like charging a mobile phone. Just turn it off when not in use.
