Specific Absorption Rates (SAR) for Wireless Phones
The SAR is a value that corresponds to the relative amount of RF
energy 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 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.
The highest reported SAR values of the SPH-A640 are:
•
AMPS: Head: 1.23 W/Kg and Body-worn: 0.401 W/Kg
•
CDMA: Head: 1.1 W/Kg and Body-worn: 0.359 W/Kg
•
PCS: Head: 1.44 W/Kg and Body-worn: 0.596 W/Kg
