THIS MOBILE PHONE MEETS THE INTERNATIONAL RECOMMENDATIONS FOR EXPOSURE TO
RADIO WAVES
Your mobile phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the limits for
exposure to radio frequency (RF) energy defined by the international standards. These recommendations have been
established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and, the Institute
of Electrical and Electronics Engineers - Standards Associations (IEEE-SA) that forcast 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 2,0 W/
kg in 10g of tissue and, is 1,6W/kg in 1g of tissue by IEEE-SA (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 Philips S890 model phone when tested for compliance against the standard was
0.21W/kg for ICNIRP recommendation and 0.302 W/kg for IEEE Standard.
For limiting the radio waves 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.
