Notes on Bluetooth Technology

A standardized radio connection system is used to transmit data between information electronics control module 1 and telephone handset (R37)/cellular telephone (R54) - Bluetooth Technology.

An additional transmitter/receiver unit is installed in the information electronics control module 1. A separate Bluetooth antenna (R152) combines the information electronics control module 1 and telephone baseplate (R126)/cellular telephone, so that the telephone handset/cellular telephone can be wireless.

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