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.
