Effective communication range
Bluetooth devices should be used within
approximately 10 meters (unobstructed
distance) of each other. The effective
communication range may become
shorter under the following conditions.
 When a person, metal object, wall
or other obstruction is between the
devices with a Bluetooth connection
 Locations where a wireless LAN is
installed
 Around microwave ovens that are in
use
 Locations where other electromagnetic
waves occur
Effects of other devices
Bluetooth devices and wireless LAN
(IEEE 802.11b/g) use the same frequency
band (2.4 GHz). When using your
Bluetooth device near a device with
wireless LAN capability, electromagnetic
interference may occur. This could result
in lower data transfer rates, noise, or
inability to connect. If this happens, try
the following remedies:
 Try connecting this system and
Bluetooth mobile phone or Bluetooth
device when you are at least 10
meters away from the wireless LAN
equipment.
 Turn off the power to the wireless LAN
equipment when using your Bluetooth
device within 10 meters.
Effects on other devices
The radio waves broadcast by this system
may interfere with the operation of some
medical devices. Since this interference
may result in malfunction, always turn
off the power on this system, Bluetooth
mobile phone and Bluetooth device in
the following locations:
 In hospitals, on trains, in airplanes,
at gas stations, and any place where
flammable gasses may be present
 Near automatic doors or fire alarms
Notes
 This system supports security functions that
comply with the Bluetooth specification
as a means of ensuring security during
communication using Bluetooth technology.
However, this security may be insufficient
depending on the setting contents and
other factors, so always be careful when
performing communication using Bluetooth
technology.
 Sony cannot be held liable in any way
for damages or other loss resulting from

 Bluetooth communication is not necessarily
guaranteed with all Bluetooth devices that
have the same profile as this system.
 Bluetooth devices connected with this system
must comply with the Bluetooth specification
prescribed by the Bluetooth SIG, Inc., and
must be certified to comply. However, even
when a device complies with the Bluetooth
specification, there may be cases where
the characteristics or specifications of the
Bluetooth device make it impossible to
connect, or may result in different control
methods, display or operation.
 Noise may occur or the audio may
cut off depending on the Bluetooth
device connected with this system,
the communications environment, or
surrounding conditions.
