What is Bluetooth
®
?
Bluetooth wireless technology provides a way for devices to
communicate with each other using short-range radio frequency instead
of wires. Any two Bluetooth devices can communicate as long as they
both have Bluetooth turned on, they are within range and they have
been paired — a quick “handshake” process that connects the two
devices. Bluetooth range is up to 10 metres (33 feet). Obstructions such
as walls or other electronics devices can cause interference or shorten
the effective range.
NOTE For optimal performance, place your headset and phone on the
same side of your body.
