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.
