Precautions

On Bluetooth communication

(NV-U83T only)

• Bluetooth wireless technology operates within

a range of about 10 m (about 30 ft).

Maximum communication range may vary
depending on obstacles (person, metal, wall,
etc.) or electromagnetic environment.

• When using the Bluetooth function, install the

unit within 60 cm (about 20 in) from the driver.

• 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 cellphone.

– 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
resulting 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 (about 30 ft) 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 cellphone 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 the cellphone in
the following locations, as it may cause an
accident:
– where inflammable gas is present, in a

hospital, train, airplane, or a petrol (gas)
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 cellphones cannot be

guaranteed.
– A cellphone featuring Bluetooth function is

required to conform to the Bluetooth standard
specified by Bluetooth SIG, and be
authenticated.

– Even if the connected cellphone conforms to

the above mentioned Bluetooth standard,
some cellphones may not be connected or
work correctly, depending on the features or
specifications of the cellphone.

– While talking on the phone hands-free, noise

may occur, depending on the model of your
cellphone or communication environment.

• Depending on the cellphone to be connected, it

may require some time to start communication.

Others

• Using the Bluetooth device may not function

on cellphones, 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.
