Specific Absorption Rate (SAR) of Mobile Phones, etc.
This model phone N-04A meets the MIC’s
*1
technical regulation for exposure to radio waves. The
technical regulation established permitted levels of radio frequency energy, based on standards that
were developed by independent scientific organizations through periodic and thorough evaluation of
scientific studies. The regulation employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit is 2 watts/kilogram (W/kg)
*2
averaged over ten grams of tissue. The limit
includes a substantial safety margin designed to assure the safety of all persons, regardless of age
and health. The value of the limit is equal to the international guidelines recommended by ICNIRP
*3
.
All phone models should be confirmed to comply with the regulation, before they are available for sale
to the public. The highest SAR value for this model phone N-04A is 0.633 W/kg. It was taken by the
Telecom Engineering Center (TELEC), a Registered Certification Agency on the Radio Law. The test
for SAR was conducted in accordance with the MIC testing procedure using standard operating
positions with the phone transmitting at its highest permitted power level in all tested frequency bands.
While there may be differences between the SAR levels of various phones and at various positions,
they all meet the MIC’s technical regulation. Although the SAR is determined at the highest certified
power level, the actual SAR of the phone during operation can be well below the maximum value.
