Bluetooth:
The term "Bluetooth" is adopted
from the English translation of a
name borne by a tenth-century
Viking king of the Danes; Harald
Blåtand or Harald Bluetooth was
renowned for his communicative-
ness.

Bluetooth devices are short-
range devices transmitting on
the license-free ISM band (Indus-
trial, Scientific, Medical) between
2.402 GHz and 2.480 GHz. They
can be operated anywhere in the
world without a license being re-
quired.
Sources of interference:
Bluetooth connections between
two or more devices can be dis-
rupted by various transient influ-
ences, including for example
interference fields of transmit-
ter masts and the like.
devices with non-compliant
Bluetooth implementations
proximity of other Bluetooth-
compatible devices
Correct pairing of the devices
is another important precondi-
tion for fault-free communication.
Please see the instructions start-
ing on page (

Note on health compatibility:
The body of scientific data
available at this time gives no
grounds for assuming that
Bluetooth can have negative
effects on human health. The
BMW Motorrad audio system
transmits at a maximum of
10 mW; a mobile phone by
contrast can have a transmit-
power rating as high as 2 W.
The ISM frequency band used
by Bluetooth is reserved for the
world-wide use of devices in the
industrial, scientific and med-
ical sectors and given the low
transmit-power ratings, Bluetooth
devices are considered safe in
terms of potential health risks.
Playback via helmet
The audio system can be con-
nected to the Bluetooth-compat-
ible BMW Motorrad communic-
ation systems. Playback in this
case is not through the speak-
ers, but by wireless transmission
through the headphones in the
helmet.
