Device Information

Theory of Operation
Bluetooth is an open wireless protocol for exchanging data over short distances from fixed and mobile
devices, creating Personal Area Networks (PANs). It was originally conceived as a wireless alternative to
RS232 data cables. It can connect several devices, overcoming problems of synchronization.
There are various versions of Bluetooth communication and the Easy Bluetooth is compatible with
versions 1.x and 2.0.
Precautions
The Easy Bluetooth uses the microwave radio frequency spectrum in the 2.4 GHz to 2.4835 GHz range.
Maximum power output from this Bluetooth radio 2.5 mW; Class 2 devices are considered less of a
potential hazard than mobile phones.
