Notes on Bluetooth technology

Bluetooth technology, a standardized radio connection, is used to transmit data between the Telephone Transceiver -R36- / Information Electronics Control Module 1 -J794- and the Telephone Handset -R37- / Cellular Telephone -R54-.

There is an additional transceiver unit in the Telephone Transceiver -R36- / Information Electronics Control Module 1 -J794-. A separate Bluetooth Antenna -R152- connects the Telephone Transceiver -R36- / Information Electronics Control Module 1 -J794- and Telephone Baseplate -R126- / Cellular Telephone -R54-, so that the Telephone Handset -R37- / Cellular Telephone -R54- can be operated wearilessly.

The Range Of The Radio Connection Is Approximately 10 m.
