Troubleshooting |

■ Radio Wave Caution

Products with Wi-Fi/BLUETOOTH use radio waves in the 

2.4 GHz and 5GHz frequency bands.

There are nations and regions where the use of particular 

5 GHz bands are prohibited outdoors, so do not use these 

products outside.

2.4 GHz radio waves are used by a variety of devices, as 

shown in lists 1 and 2 below.

1. Devices which use a 2.4 GHz radio wave frequency

•  Cordless phones

•  Cordless facsimiles

•  Microwave ovens

•  Wireless LAN devices (IEEE802.11b/g/n)

•  Wireless AV equipment

•  Wireless controllers for game systems

•  Microwave oven-based health aids

•  Video transmitter

•  Specific type of external monitor and LCD display

2. Less common devices which use a 2.4 GHz radio wave 

frequency

•  Anti-theft systems

•  Amateur radio stations (HAM)

•  Warehouse logistic management systems

•  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

•  Switch off the devices which emit the radio wave.

•  Place the interfering devices away from the AV 

receiver.

•  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.

•  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:

•  In reinforced concrete buildings or steel framed or iron 

framed buildings.

•  Near large metallic furniture.

•  In a crowd of people or near a building or obstacle.

•  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.

•  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

The radio waves received by the AV receiver include the 

radio wave coming directly from the devices and waves 

coming from various directions due to reflections by walls, 

furniture and building (reflected waves). The reflected 

waves (due to obstacles and reflecting objects) further 

produce a variety of reflected waves as well as variation 

in reception condition depending on locations. If the audio 

cannot be received properly due to this phenomenon, try 

moving the location of the wireless LAN device a little.

Also note that audio may be interrupted due to the 

reflected waves when a person crosses or approaches 

the space between the AV receiver and the wireless LAN 

device.

•  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.

•  Operation in all environment is not guaranteed for 

wireless LAN. The communication may not be possible 

or have desirable communication speed.

■ Precautions

•  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.

•  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 

devices, confirm with the medical electronic device maker 

or dealer for the effect of the radio wave.
