5.5 Using Bluetooth
Bluetooth is a short-range wireless communications technology. Devices
with Bluetooth capabilities can exchange information over a distance of
about 8 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:
• Beam information, such as files, appointments, tasks and contact
cards between devices that have Bluetooth capabilities.
• Synchronize information between your phone and computer via
Bluetooth.
• Use a Bluetooth service. Once you connect your phone to another
device or computer using Bluetooth, you can locate and use any of
the services available on that device.
• Use your phone as a Bluetooth modem for a computer.
Bluetooth modes
Bluetooth on your phone operates in three different modes:
1. On. Bluetooth is turned on. Your phone can detect other Bluetooth-
enabled devices, but not vice versa.
2. Off. Bluetooth is turned off. In this mode, you can neither send nor
receive information using Bluetooth. You might want to turn off the
radio at times to conserve battery power or in situations where radio
use is prohibited, such as onboard an aircraft and in hospitals.
3. Discoverable. Bluetooth is turned on and all other Bluetooth-enabled
devices within a range of 5 meters can detect your phone.
Note By default, Bluetooth is turned off. If you turn it on and then turn off your
phone, Bluetooth also turns off. When you turn on your phone again,
Bluetooth automatically turns on.
