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 33 feet (10 metres). Obstructions, such as walls or other
electronic devices, can cause interference or shorten the effective range. For optimal
performance, place your headset and phone on the same side of your body.
