Notes on Bluetooth® technology

A standardized radio connection system is used to transmit data between Information Electronics Control Module 1 -J794- and Telephone Handset -R37- /Cellular Telephone -R54- /Telephone Handset 2 -R116- - Bluetooth® Technology.

An additional transmitter/receiver unit is installed in the Information Electronics Control Module 1 -J794-. A separate Bluetooth Antenna -R152- connects the Information Electronics Control Module 1 -J794- and Telephone Baseplate -R126- /Cellular Telephone -R54- /Rear Telephone Charging Station -R151-, so that the Telephone Handset - R37- /Cellular Telephone -R54- /Telephone Handset 2 -R116- can be used wireless.

The range of the radio wave connection is approximately 10 meters.
