78 - Specific Absorption Rate Data
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.
1 The SAR limit recommended by international guidelines (ICNIRP) for mobile
phones used by the public is 2.0 watts/kilogram (W/kg) averaged over ten grams of
tissue. The limit incorporates a substantial margin for safety to give additional
protection for the public and to account for any variations in measurements.
