r Discrimination systems for train or emergency
vehicles
If these devices and the AV receiver are used at the same
time, the audio may be undesirably stopped or disturbed
due to a radio wave interference.
Suggestions for improvement
r Switch off the devices which emit the radio wave.
r Place the interfering devices away from the AV
receiver.
r The AV receiver uses radio wave, and a third person can
receive the wave on purpose or accidentally. Do not use
the communication for important or fatal matters.
r We assume no responsibility whatsoever for any error
or damage of network environment or access device
resulting from the use of this apparatus.
Confirm with the provider or access device maker for
more information.
Scope of Operation
Use of the AV receiver is limited to home use.
(Transmission distances may be reduced depending on
communication environment.)
In the following locations, poor condition or inability to
receive radio waves may cause the audio to be interrupted
or stopped:
r In reinforced concrete buildings or steel framed or iron
framed buildings.
r Near large metallic furniture.
r In a crowd of people or near a building or obstacle.
r In a location exposed to the magnetic field, static
electricity or radio wave interference from radio
communication equipment using the same frequency
band (2.4 GHz) as the AV receiver, such as a 2.4 GHz
wireless LAN device (IEEE802.11b/g/n) or microwave
oven.
r If you live in a heavily populated residential area
(apartment, townhouse, etc.) and if your neighbor’s
microwave oven is placed near your AV receiver, you
may experience radio wave interference. If this occurs,
move your AV receiver to a different place.
When the microwave oven is not in use, there will be no
radio wave interference.
Radio Wave Reflections
r We assume no responsibility whatsoever for any
damages resulting from the use of this apparatus except
in the cases deemed acceptable under the applicable
laws and regulations.
r Operation in all environment is not guaranteed for
wireless LAN. The communication may not be possible
or have desirable communication speed.
Precautions
r Do not use this apparatus near an electronic device
handling high-accuracy controls or weak signals. Doing
so may cause an accident due to a malfunction of the
device.
r Do not use this apparatus in use prohibited location
such as an aircraft equipment or a hospital. Doing so
may cause an accident due to a malfunction of an
electronic device or an electro-medical apparatus. Follow
the instructions of the medical facilities.
Electronic device which requires cautions
Hearing aid, pace maker, other medical electronic devices,
fire alarm, automatic door, and other automatic control
device.
When using a pace maker or other medical electronic
r devices, confirm with the medical electronic device
r maker or dealer for the effect of the radio wave.
