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 A640 are:
CDMA mode (Part 22):
Head: 1.23 W/kg; Body-worn: 0.401 W/kg
PCS mode (Part 24):
Head: 1.44 W/kg; Body-worn: 0.596 W/kg
