Safety precautions107Specific Absorption Rate (SAR)The SAR is a value that corresponds to the relative amount of RF energyabsorbed in the head of a user of a wireless handset.The SAR value of a wireless device is the result of an extensive testing,measuring and calculation process. It does not represent how much RF thephone emits. All devices are tested at their highest value in strict laboratorysettings. But when in operation, the SAR of a device can be substantiallyless than the level reported to the FCC. This is because of a variety of factorsincluding its proximity to a base station antenna, design and other factors.What is important to remember is that each device meets strict federalguidelines. Variations in SARs do not represent a variation in safety.All wireless devices must meet the federal standard, which incorporates asubstantial margin of safety. SAR values at or below the federal standard of 1.6W/kg are considered safe for use by the public.Maximum measured SAR values for the SGH-i957 are:Cellular/PCS WCDMA/GSM/EDGE: 1.04 W/kgWLAN: 0.88 W/kgCorrect disposal of this productThe product and its electronic accessories (e.g., charger, headset, USB cable)should not be disposed of with other household waste at the end of theirworking life.
