• Do not insert the AC adapter into a power
outlet where the connection remains
loose despite inserting the prongs all the
way into the outlet. Heat may be gener-
ated which could lead to fire. Consult
with the retailer or an electrician regard-
ing replacement of the power outlet.
Radio wave reflections
The radio waves received by the wireless
speaker include the radio wave coming
directly from the transmitter (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 wireless speaker a little.
Also note that audio may be interrupted due
to the reflected waves when a person crosses
or approaches the space between the
transmitter and wireless speaker.
Radio wave caution
This wireless speaker system 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 system nearby such devices,
or make sure these devices are switched off
during use. You can also try switching the
channel on the transmitter (see “Transmitter”
on page 10) for better reception.
• Cordless phones
• Cordless FAX units
• Wireless broadband routers
• Wireless AV equipment
• Microwave-based health aids
• Microwave ovens
• Wireless controllers for game systems
• Bluetooth equipment
• Some baby monitors
Other, less common, equipment that may
operate on the same frequency:
• Anti-theft systems
• Warehouse logistic management
systems
• Amateur radio stations (HAM)
• Discrimination systems for train or
emergency vehicles
• If the transmitter is used near A/V
equipment with an antenna input
terminal, such as a TV, VCR, BS tuner or
CS tuner, you may experience noise
interference on a TV near the transmitter.
In such cases, place the transmitter at a
larger distance from the antenna input
terminal of the A/V equipment.
• If there is something obstructing the path
between the transmitter and the wireless
speaker (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 equipment is limited to home use.
(Transmission distances may be reduced
depending on communication
environments.)
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 inter-
ference from radio communication
equipment using the same frequency
band (2.4 GHz) as this system, such as a
Bluetooth device, radio LAN device or
microwave oven.
• If you live in a heavily populated residen-
tial area (apartment, townhouse, etc.)
and if your neighbor’s microwave is
placed near your system, you may experi-
ence radio wave interference or no sound
from the speaker. If this occurs, move
your unit to a different place. When the
microwave is not in use, there will be no
radio wave interference.
