Using Bluetooth
Bluetooth is a short-range wireless communications technology.
Devices with Bluetooth capabilities can exchange information over a
distance of about 10 meters without requiring a physical connection.
You can even beam information to a device in a different room, as long
as it is within the Bluetooth signal coverage range.
Bluetooth can be used in the following ways:
To beam information, such as files, appointments, tasks, and
contact cards between devices that have Bluetooth capabilities.
To synchronize information between your device and computer
via Bluetooth.
To use a Bluetooth-enabled headset (or other Bluetooth-enabled
hands-free device such as a car kit) with your device for hands-
free phone conversations.
To use a Bluetooth service. Once you connect to another device
or computer using Bluetooth, you can locate and use any of the
services available on that device.
To create a connection between your device and another
Bluetooth-enabled phone to use that phone as a modem.
Bluetooth Modes
Bluetooth on your device operates in three different modes:
On. Bluetooth is turned on. Your device can detect other
Bluetooth-enabled devices, but cannot be detected by those
devices.
Off. Bluetooth is turned off. In this mode, you can neither
send nor receive information using Bluetooth. You might
want to turn Bluetooth off at times in order to conserve
battery power, or in situations where using a wireless device
is prohibited, such as onboard an aircraft and in hospitals.
Visible. Bluetooth is turned on, and all other Bluetooth-
enabled devices can detect your device.

Section 9: Getting Connected
By default, Bluetooth is turned off. If you turn it on, and
then turn off your device, Bluetooth also turns off. When
you turn on your device again, Bluetooth automatically
turns on.
