Notes on Bluetooth technology

A standardized radio connection is used for data transfer between the Information Electronics Control Module 1 -J794- and Cellular Telephone -R54- - Bluetooth Technology.

An additional transmitter/receiver unit is installed in the Information Electronics Control Module 1 -J794-. A Bluetooth Antenna -R152- connects the Information Electronics Control Module 1 -J794- and the Cellular Telephone -R54- so that the Cellular Telephone -R54- can be operated without a wire connection.

The range of the radio connection is approximately 10 m.
