have been established by the International Commission on Non-Ionizing
Radiation Protection (ICNIRP) and, the Institute of Electrical and
Electronics Engineers (IEEE) that forecast a substantial safety margin for
assuring the protection of all persons, regardless of age and health.
The exposure recommendations for mobile phones use a measurement
unit known as the Specific Absorption Rate (SAR). The SAR limit
recommended by the ICNIRP for the mobile phones used by the general
public is 2.0W/kg averaged over ten grams of tissue and, is 1,6W/kg
averaged over one gram of tissue by IEEE Std 1528 for the head.
Tests for SAR have been conducted using recommended operating
positions with the mobile phone transmitting at its highest certified power
level in all tested frequency bands. Although the SAR is determined at
the highest certified power level, the actual SAR levels of the mobile
phone while operating are generally below the maximum SAR value.
This is because the phone is designed to operate at multiple power levels
so as to use only the power required to reach the network. In general, the
closer you are to a base station antenna, the lower the power output.
While there may be differences between the SAR levels of various
phones and at various positions, they all meet the international protection
standards for exposure to radio waves.
The highest SAR value for this model phone when tested was 1.19W/kg
at ear and 0.899 W/kg for use close to the body.
For limiting radio wave exposure, it is recommended to reduce the
mobile phone call duration or to use a headset. The purpose of those
precautions is to take the mobile phone away from the head and the
body.
For body-worn operation, this phone has been tested and meets FCC RF
exposure guidelines when used with an accessory that contains no metal
and that positions the handset a minimum of 1.5cm from the body. Use of
other accessories may not ensure compliance with FCC RF exposure
guidelines.
