Bluetooth® Audio playback

Radio wave caution

This unit uses a 2.4 GHz radio wave frequency, which is a

band used by other wireless systems (see list below). To

prevent noise or interrupted communication, do not use this

unit nearby such devices, or make sure these devices are

switched off during use.

• Cordless phones

• Cordless facsimiles

• Microwave ovens

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

• Wireless AV equipment

• Wireless controllers for game systems

• Microwave-based health aids

• Some baby monitors

Other, less common, equipment that may operate on the

same frequency:

• Anti-theft systems

• Amateur radio stations (HAM)

• Warehouse logistic management systems

• Discrimination systems for train or emergency vehicles

Note

• In the event noise appears in your television image, there

is the possibility that a Bluetooth wireless technology

enabled device or this unit (including products

supported by this unit) are causing signal interference

with the antenna input connector of your television,

video, satellite tuner, etc. In this event, increase the

distance between the antenna input connector and the

Bluetooth wireless technology enabled device or this

unit (including products supported by this unit).

• If there is something obstructing the path between this

unit (including devices supported by this unit) and the

device equipped with Bluetooth wireless technology

(such as a metal door, concrete wall, or insulation

containing tinfoil), you may need to change the location

of your system to prevent signal noise and interruptions.

Scope of operation

Use of this unit 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 this unit, such as a 2.4 GHz wireless

LAN device (IEEE802.11b/g) or microwave oven.

• If you live in a heavily populated residential area

(apartment, townhouse, etc.) and if your neighbor's

microwave is placed near your system, you may

experience radio wave interference. If this occurs, move

your unit to a different place. When the microwave is not

in use, there will be no radio wave interference.

Radio wave reflections

The radio waves received by this unit include the radio wave

coming directly from the device equipped with Bluetooth

wireless technology (direct wave) 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 device equipped with Bluetooth wireless technology a

little. Also note that audio may be interrupted due to the

reflected waves when a person crosses or approaches the

space between this unit and the device equipped with

Bluetooth wireless technology.

Precautions regarding connections to

products supported by this unit

• Complete connections for all devices supported by this

unit, including all audio cords and power cables before

connecting them to this unit.

• After completing connections to this unit, check the

audio and power cables to confirm that they not twisted

together.

• When disconnecting this unit, confirm that you have

sufficient working space in the surrounding area.

• When changing connections of audio or other cables for

products supported by this unit, confirm that you have

sufficient working space in the surrounding area.
