Do not expose the walkie talkie to blazing sun for quite a long time or put it near a heating
appliance.
Do not put the walkie talkie at places where there is too much dust, damp or water splash or
on instable surface.
If any abnormal smell or fume is found from the walkie talkie, immediately turn off its power
and contact the local distributer.
Using a walkie talkie in driving may violate traffic laws. Please inquire or consult the local
transportation administration body about it and observe the local traffic laws.
Do not use options not designated by this company.
Attention
 The walkie talkie is designed to use 13.8V DC (± 15%) power supply! Never use 24V
batteries. Prior to installing it on the vehicle, please inspect the battery polarity and
voltage of the vehicle.
 Only use the DC power line attached or designated by this company.
 Never insert a metal object into the cooling fan.
Warning
 Do not cut down or remove the fuse holder of the DC wire. Wrong connection may
lead to fume and further fire.
 To ensure passengers' safety, please use the attached installation support and screw
set in the installation of the walkie talkie and be sure that it will not slip out in case of
vehicle collision.
 Lack of proper protection or isolation of various electronic devices in the vehicle
from radio RF energy during the transmission of the walkie talkie may lead to their
damage. For example, electronic fuel injector, anti-slide brake and navigation control
system are easy to be damaged. If your vehicle is furnished with such devices, please
consult the vehicle distributor on whether it is necessary to protect them in
transmission.
