! ow Bluetooth "or#s : Is

RADIATION a

PROBLEM

$ Bluetooth sends out wea#

RADIO signals to

CONNECT up to eight devices to eachother within a range of about %& feet.

This is the same

TECHNOLOGY used by baby

MONITORS and

PORTABLE phones.

Bluetooth uses a

TECHNIQUE called 'spread -

SPECTRUM fre(uency hopping' to ensure that each device is on a

DIFFERENTFREQUENCY and therefore they do not

INVOLVE

with one another.

This gives usersthe

CONVENIENCE of being able to

CONTROL a number of

ELECTRONIC devices inthe home or wor#place from a single Bluetooth - enabled device, such as a cell phone.

Because it

EMITS RADIO waves, some worry that Bluetooth

RADIATION could causehealth

PROBLEMS

SENSITIVE to the waves sent out by microwaves, cellphones and

RADIO towers often complain of

NAUSEA

, headaches and other bothersome

SYMPTONS ASSOCIATED with their e * posure.

! owever, the Bluetoothsignal at %

MILLIWATT is e * tremely low,

COMPARED to some cell phones, which may

EMIT up to +

WATTS

.

The signal is also

TRANSMMITED throughout a space and not ina single, powerful beam.

Bluetooth

RADIATION is

CONSIDERED far less bothersomethan cell phone

RADIATION.
