On Bluetooth
communication
• 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
• 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:
– Use this receiver at least 10 meters
away from the wireless LAN device.
– Turn off the power to the wireless LAN
equipment when using your Bluetooth
device within 10 meters.
– Install this receiver and Bluetooth
device as closer to each other as
possible.
• The radio waves broadcast by this
receiver may interfere with the operation
of some medical devices. Since this
interference may result in malfunction,
always turn off the power on this receiver
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
• This receiver supports security functions
that comply with the Bluetooth
specification to ensure secure connection
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
information leaks during communication
using Bluetooth technology.
• Bluetooth communication is not
necessarily guaranteed with all Bluetooth
devices that have the same profile as this
receiver.
• Bluetooth devices connected with this
receiver 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 receiver, the
communications environment, or
surrounding conditions.
If you have any questions or problems
concerning your receiver, please consult
your nearest Sony dealer.
