14Specific Absorption Rate (SAR)certification informationThe SAR is a value that corresponds to the relative amount of RFenergy absorbed in the head of a user of a wireless handset.The SAR value of a phone is the result of an extensive testing,measuring and calculation process. It does not represent howmuch RF the phone emits. All phone models are tested at theirhighest value in strict laboratory settings. But when in operation,the SAR of a phone can be substantially less than the levelreported to Industry Canada. This is because of a variety of factorsincluding its proximity to a base station antenna, phone designand other factors. What is important to remember is that eachphone meets strict federal guidelines. Variations in SARs do notrepresent a variation in safety.All phones must meet the federal standard, which incorporatesa substantial margin of safety. As stated above, variations in SARvalues between different model phones do not mean variations insafety. SAR values at or below the federal standard of 1.6 W/kg areconsidered safe for use by the public.The highest reported SAR values for the SM-G903W are:Head : 0.74 W/kgBody : 1.08 W/kgThis phone has been tested and meets RF exposure guidelineswhen used with an accessory that contains no metal and thatpositions the mobile device a minimum of 1.5 cm from the body.Organizations such as the World Health Organization and theUS Food and Drug Administration have suggested that if peopleare concerned and want to reduce their exposure, they coulduse a hands-free accessory to keep the wireless device awayfrom the head and body during use, or reduce the amountof time spent using the device.
