Safety notes While the transmitting power of Bluetooth

Systems is far below

(up to a factor of 1000) the radiated power levels of hand held GSM

phones and is generally not regarded as dangerous, interference

effects between radio transmitters and other electronic devices

cannot be excluded in sensitive environments, like medical centers,

and airplanes. Operators may request that Bluetooth

devices must

remain switched off in such areas.
