specific absorption rate data

SAR data

This model meets international guidelines for exposure

to radio waves.

Your mobile device is a radio transmitter and receiver. It is designed not to

exceed the limits for exposure to radio waves recommended by

international guidelines. These guidelines were developed by the

independent scientific organization ICNIRP and include safety margins

designed to assure the protection of all persons, regardless of age and

health.

The guidelines use a unit of measurement known as the Specific

Absorption Rate, or SAR. The ICNIRP SAR limit for mobiles devices used by

the general public is 2 W/kg and the highest SAR value for this device

when tested at the ear was 1.05 W/kg.

functions, they can be used in other positions, such as on the body as

described in this user guide.

In this case, the highest tested SAR value is

0.45 W/kg.

As SAR is measured utilizing the device's 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.

While there may be differences between the SAR levels of various phones

and at various positions, they all meet the governmental requirements for

safe exposure. Please note that improvements to this product model could

cause differences in the SAR value for later products; in all cases, products

are designed to be within the guidelines.

The World Health Organization has stated that present scientific

information does not indicate the need for any special precautions for the

use of mobile devices. They note that if you want to reduce your exposure

SAR data

As mobile devices offer a range of

6803535D08

then you can do so by limiting the length of calls or using a "hands-free"

device to keep the mobile phone away from the head and body.

1. The tests are carried out in accordance with international guidelines for

testing. The limit incorporates a substantial margin for safety to give additional

protection for the public and to account for any variations in measurements.
