• If there is something obstructing the path
between this unit (including devices
supported by this unit) and the device
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
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
• 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
(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
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
