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.

Notes on MOST bus

The optical Data bus "MOST bus" is used in addition to the CAN bus.

A fiber-optic cable is used as a "connecting cable". Fiber optic cables are routed inside corrugated tubes for protection.

Replace complete fiber optic cable if possible.

The front surface of the connectors must not be dirty.

If disconnecting the connectors: Attach Fiber-Optic Repair Set - Connector Protective Caps VAS 6223/9.
