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) 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 hands free, 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 this manual, consult 
your nearest Sony dealer.
Maintenance
Replacing the lithium battery of the 
card 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
