Bluetooth ®
Your phone has a Bluetooth interface. This
makes it possible to establish a wireless
connection of your phone with a headset of
a car kit, or with other Bluetooth-enabled
devices.
In order to establish a secure link between
the devices and to prevent a third party from
having access to your phone, you should
observe the following points:
• The initial connection between two devic-
es, what is called "pairing", should take
place in familiar surroundings.
• Both devices must be able to identify
themselves one time by using a password/
PIN. To ensure sufficient security, you
should choose a 16-digit number combina-
tion for a password that would be difficult
to guess (if a PIN has not been assigned).
• An automatic connection acceptance
("connection without confirmation") should
only be used in exceptional cases.
• In general, only trustworthy devices should
be linked in order to minimize security
risks.
• The name of your phone is transmitted
in a Bluetooth connection. The factory
default is the "Bluetooth ID". The first time
Bluetooth is activated, or later in the
Bluetooth menu, you can change this
name (My BT name
• If Bluetooth is not needed, this function
should be deactivated.
Before using Bluetooth accessories, or a
mobile phone inside a vehicle, check the
vehicle user guide for any limitations on the
use of these products.
