Safety notes
While the transmitting power of Bluetooth
TM
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
TM
devices must
remain switched off in such areas.
