172 Section 4A. Important Safety Information
Specific Absorption Rates (SAR) for Wireless
Phones
The SAR value corresponds to the relative amount of RF
energy absorbed into 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 M520 are:
Cellular CDMA mode (Part 22):
Head: 1.08 W/kg; Body-worn: 0.672W/kg
PCS mode (Part 24):
Head: 0.993 W/kg; Body-worn: 0.761 W/kg
