contains no metal and that positions the handset a minimum of
15 mm from the body. Use of other accessories may not ensure
compliance with RF exposure guidelines.
The guidelines use a unit of measurement known as the
Specific Absorption Rate, or SAR. The SAR limit for mobile
devices is 2 W/kg and the highest SAR value for this device
when tested at the ear was 1.62 W/kg (10g)*. As mobile devices
offer a range of functions, they can be used in other positions,
such as on the body. In the case where the phone is worn
directly on the body, the highest tested SAR value is
1.09 W/kg (10g)*.

As SAR is measured utilizing the devices highest transmitting
power the actual SAR of this device while operating is typically
below that indicated above. This is due to automatic changes to
the power level of the device to ensure it only uses the minimum
level required to reach the network.

The WHO (World Health Organization) has stated that current
scientific information does not indicate the need for special
precautions for the use of mobile phones. However, if individual
users are concerned, they may choose to limit exposure to
themselves and to their children, by either limiting the length of
calls, or by using headsets or "hands-free" devices to keep the
phone away from their body and head.
