Caution! High frequency signals in
vehicles
HF signals can, under circumstances, negatively influence the
function of not properly installed or not sufficiently shielded
electronic systems in vehicles, e.g. electronic ABS, electronic
tempo controllers and airbag systems. For further informa
tion about your vehicle or its possible ancillaries make
contact with the respective manufacturer or their repre-
sentative.
Introduction, trademark rights
Bluetooth
®
is a wireless communication system with
a short range. It makes possible wireless connections
between Bluetooth
®
appliances, such as for example
mobile telephones, PDA and PCs. Bluetooth
®
relates
itself to a worldwide standard for operation in the inter-
nationally recognised ISM Frequency Range (Industrial,
Scientific and Medical). Within the ISM Frequency Range
(2.402 - 2.480 GHz), a data transfer range of ca. 10 meters
(class II) is achieved. The disturbance susceptibility through
other users of the ISM Frequency Range, such as for
example microwaves, WLAN (802.116) or garage door
openers, is minimised by so-called “Frequency-Hopping“.
With Frequency-Hopping, a change of frequency levels
takes place at up to 1600 times per second, thereby
Bluetooth
®
is also reckoned to be relatively tap-proof.
However, data transferred via a radio link can be inter-
cepted by unauthorised third parties.
The Bluetooth
®
logotype and logos are registered trade-
marks of Bluetooth SIG, Inc. All other names and brands

The HSP (Headset-Profil) makes possible standard func-
tions such as voice transference, as well as the accept-
ance and rejection of calls.
The HFP (Handsfree-Profil) makes possible the hands-free
call functions of a mobile telephone, for example with the
help of voice commands.
