CAUTION
Do not place this device near a heating in-
strument or in a location exposed to direct
sunlight.
This may result in deformation and discolor-
ation.
Do not place this device in a location where
there is a lot of dust and humidity.
Doing so may result in fire and equipment
failure.
Stay as far away from the antenna as pos-
sible during transmission.
Long-term exposure to electromagnetic radia-
tion may have a negative effect on the human
body.
Do not wipe the case using thinner and
benzene etc.
Please use a soft and dry piece of cloth to
wipe away the stains on the case.
Keep out of the reach of small children.
If not, this may result in injuries to children.
Do not put heavy objects on top of the
power cord and connection cables.
This may damage the power cord and connec-
tion cables, resulting in fire and electric shock.
Do not transmit near the television and
radio.
This may result in electromagnetic interfer-
ence.
Do not use optional products other than
those specified by our company.
If not, this may result in equipment failure.
When using the device in a hybrid car or
fuel-saving car, make sure to check with
the car manufacturer before using.
The device may not be able to receive trans-
missions normally due to the influence of nois-
es from the electrical devices (inverters etc.)
fitted in the car.
For safety reasons, switch off the power
and pull out the DC power cord connect-
ed to the DC power connector when the
device is not going to be used for a long
period of time.
If not, this may result in fire and overheating.
Do not throw or subject the device to
strong impact forces.
This may result in equipment failure.

When used for a long period of time, the tem-
perature of the heat radiating parts will get
higher, resulting in burns when touched.
Do not open the case of the product except
when replacing the fuse and when install-
ing items sold separately.
This may result in injury, electric shock and
equipment failure.
