BLUETOOTH wireless technology
Supported BLUETOOTH version and profiles
Profile refers to a standard set of functions for various BLUETOOTH
product features. Refer to “Specifications” (page 27) for the
BLUETOOTH version and profiles supported by this system.
 To use the BLUETOOTH function, the BLUETOOTH device to be
connected must support the same profile as this system. Even if the
device supports the same profile, the functions may differ because of
the specifications of the BLUETOOTH device.
 Audio playback on this system may be delayed from that on the
BLUETOOTH device because of the characteristics of the BLUETOOTH
wireless technology.
Effective communication range
BLUETOOTH devices should be used within approximately 10 meters
(33 feet) (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
devices with a BLUETOOTH connection
 Locations where a wireless LAN is installed
 Around microwave ovens that are in use
 Locations where other electromagnetic waves are generated
Effects of other devices
BLUETOOTH devices and wireless LAN (IEEE 802.11b/g) equipment 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:
 Connect this system and BLUETOOTH mobile phone or BLUETOOTH
device when you are at least 10 meters (33 feet) away from the
wireless LAN equipment.
 Turn off the power to the wireless LAN equipment when using your
BLUETOOTH device within 10 meters (33 feet).
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 to this system,
BLUETOOTH mobile phone and BLUETOOTH device in the following
locations:
 In hospitals, on trains or airplanes, at gas stations, and any place
where flammable gasses may be present
 Near automatic doors or fire alarms
 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 settings and other factors. So
always be careful when performing communication using BLUETOOTH
technology.
 Sony shall not be held liable in any way for damages or other loss
resulting from information leaks during communication using
BLUETOOTH technology.
 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.
