Protos Integral Bluetooth Communication

4 User Bluetooth Communication System and Phone Compatibility

The BT-COM allows the connection of 4 BT-COM units providing uninterrupted intercom connection between four operators. There is also the ability for each unit to be connected simultaneously with a mobile phone via Bluetooth. Accepting phone calls can be done hands-free by pressing the multifunction button with no need to remove the phone from a pocket. Once an outgoing phone call is executed from the hand-held device, the conversation can be carried out hands-free via the BT-COM. The conference function allows another participant to be added and the distance can be extended as long as a mobile network is available.

The Protos® electret microphone diminishes unnecessary background noises by up to 20 dB whilst always guaranteeing clearly understandable voices. Background noises remain perceptible, allowing any external danger situations to be recognised.

Bluetooth allows interference-free communication in areas where there are strong radio frequencies and Bluetooth connection does not incur any licence charges.
