compatibility with your computer.
NOTES:
There may be restrictions on using Bluetooth technology in some locations. Check
with your local authorities or service provider.
Features using Bluetooth technology, or allowing such features to run in the
background while using other features, increase the demand on battery power and
reduces the battery life.
Bluetooth technology enables wireless connections between electronic
devices. A Bluetooth connection can be used to send files or to connect
wirelessly to compatible devices using Bluetooth technology, such as
cellular phones and PDAs.
Since devices using Bluetooth technology communicate using radio
waves, your computer and the other devices do not need to be in direct
line-of-sight. Your computer and the other device only need to be within
a maximum of 10 meters of each other, although the connection can be
subject to interference from obstructions such as walls or from other
electronic devices.
