Notes on Bluetooth Technology
A standardized radio connection system is used to transmit data between the Information Electronics Control Module 1 -J794- and Telephone Handset -R37- /Cellular Telephone -R54- - 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-, so that the Telephone Handset -R37- /Cellular Telephone -R54- can be operated wirelessly.
The range of the radio connection is approximately 10 m.
