Radio wave reflections
The radio waves received by the receiver
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 2.4GHz
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 16) for better reception.
• Cordless phones
• 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 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.
• 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.
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 homes
made of metallic structural members.
• Near large metallic furniture.
• In a crowd of people or near a building or
obstacle.
• 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 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.
