The SAR value of a phone is the result of an extensive testing, 
measuring and calculation process. It does not represent how much RF 
the phone emits. All phone models are tested at their highest value in 
strict laboratory settings. But when in operation, the SAR of a phone 
can be substantially less than the level reported to the FCC. This is 
because of a variety of factors including its proximity to a base station 
antenna, phone design and other factors. What is important to 
remember is that each phone meets strict federal guidelines. Variations 
in SARs do not represent a variation in safety. 
All phones must meet the federal standard, which incorporates a 
substantial margin of safety. As stated above, variations in SAR values 
between different model phones do not mean variations in safety. SAR 
values at or below the federal standard of 1.6 W/kg are considered safe 
for use by the public.
