The exposure guidelines are based on the Specific Absorption Rate (SAR), which is an expression of the amount of radio

frequency (RF) power deposited in the head or body when the device is transmitting. The ICNIRP SAR limit for mobile

devices is 2.0 W/kg averaged over 10 grams of tissue.
SAR tests are carried out with the device in standard operating positions, transmitting at its highest certified power

level, in all its frequency bands. The maximum recorded SAR values for this device are:

Maximum SAR value

Frequency bands used when

Maximum SAR value was recorded

When held against the head

0.63 W/kg over 10g

4-slot GPRS 850 and WLAN 2450

When operated at a separation

distance of 5/8 inch (1.5

centimeters) from the body

0.50 W/kg over 10g

4-slot GPRS 850 and WLAN 2450

Your mobile device is also designed to meet the United States Federal Communications Commission (FCC) and Industry

Canada SAR (IC) guidelines. FCC ratings for your device and more information on SAR can be found at

transition.fcc.gov/oet/rfsafety/sar.html

. Information on IC SAR can be found at 

www.ic.gc.ca

.

This device meets RF exposure guidelines when used against the head or when positioned at least 5/8 inch (1.5

centimeters) away from the body. When a carry case, belt clip or other form of device holder is used for body-worn

operation, it should not contain metal and should provide at least the above stated separation distance from the body.
To send data or messages, a good connection to the network is needed. Sending may be delayed until such a connection

is available. Follow the separation distance instructions until the sending is finished.
During general use, the SAR values are usually well below the values stated above. This is because, for purposes of

system efficiency and to minimize interference on the network, the operating power of your mobile is automatically

decreased when full power is not needed for the call. The lower the power output, the lower the SAR value.
Device models may have different versions and more than one value. Component and design changes may occur over

time and some changes could affect SAR values. The latest available SAR information for this and other Microsoft Mobile

device models can be found a

sar.microsoft.com

.

The World Health Organization (WHO) has stated that current scientific information does not indicate the need for any

special precautions when using mobile devices. If you are interested in reducing your exposure, they recommend you

limit your usage or use a hands-free kit to keep the device away from your head and body. For more information and

explanations and discussions on RF exposure, go to the WHO website at
