About BLUETOOTH function
What is BLUETOOTH technology?
 BLUETOOTH wireless technology is a short-range
wireless technology that enables wireless data
communication between digital devices, such as
a cellular phone and a headset. BLUETOOTH
wireless technology operates within a range of
about 10 m (about 33 feet). Connecting two
devices is common, but some devices can be
connected to multiple devices at the same time.
 You do not need to use a cable for connection
since BLUETOOTH technology is a wireless
technology, neither is it necessary for the devices
to face one another, such is the case with infrared
technology. For example, you can use such a
device in a bag or pocket.
 BLUETOOTH technology is an international
standard supported by millions of companies all
over the world, and employed by various
companies worldwide.
On BLUETOOTH communication
 BLUETOOTH wireless technology operates within
a range of about 10 m.
Maximum communication range may vary
depending on obstacles (person, metal, wall, etc.)
or electromagnetic environment.
 The following conditions may affect the sensitivity
of BLUETOOTH communication.
 There is an obstacle such as a person, metal, or
wall between this unit and BLUETOOTH device.
 A device using 2.4 GHz frequency, such as a
wireless LAN device, cordless telephone, or
microwave oven, is in use near this unit.
 Because BLUETOOTH devices and wireless LAN
(IEEE802.11b/g/n/ac) use the same frequency,
microwave interference may occur and result in
communication speed deterioration, noise, or
invalid connection if this unit is used near a
wireless LAN device. In such as case, perform the
following.
 Use this unit at least 10 m away from the
wireless LAN device.
 If this unit is used within 10 m of a wireless LAN
device, turn off the wireless LAN device.
 Install this unit and BLUETOOTH device as near
to each other as possible.
 Microwaves emitting from a BLUETOOTH device
may affect the operation of electronic medical
devices. Turn off this unit and other BLUETOOTH
devices in the following locations, as it may cause
an accident.
 where inflammable gas is present, in a hospital,
train, airplane, or petrol station
 near automatic doors or a fire alarm

 This unit supports security capabilities that
comply with the BLUETOOTH standard to provide
a secure connection when the BLUETOOTH
wireless technology is used, but security may not
be enough depending on the setting. Be careful
when communicating using BLUETOOTH wireless
technology.
 We do not take any responsibility for the leakage
of information during BLUETOOTH
communication.
 Connection with all BLUETOOTH devices cannot
be guaranteed.
 A device featuring BLUETOOTH function is
required to conform to the BLUETOOTH
standard specified by BLUETOOTH SIG, and be
authenticated.
 Even if the connected device conforms to the
above mentioned BLUETOOTH standard, some
devices may not be connected or work
correctly, depending on the features or
specifications of the device.
 While talking on the phone handsfree, noise
may occur, depending on the device or
communication environment.
 Depending on the device to be connected, it may
require some time to start communication.
Others
 Using the BLUETOOTH device may not function on
cellular phones, depending on radio wave
conditions and location where the equipment is
being used.
 If you experience discomfort after using the
BLUETOOTH device, stop using the BLUETOOTH
device immediately. Should any problem persist,
consult your nearest Sony dealer.
If you have any questions or problems concerning
your unit that are not covered in these Operating
Instructions, consult your nearest Sony dealer.

Maintenance

Replacing the lithium battery of the
remote commander
Under normal conditions, the battery will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
remote commander becomes shorter. Replace the
battery with a new CR2025 lithium battery. Use of
any other battery may present a risk of fire or
explosion.
