The exposure limit set by the FCC for wireless mobile phones employs a unit of measurement known
as the Specific Absorption Rate (SAR). The SAR is a measure of the rate of absorption of RF energy by
the human body expressed in units of watts per kilogram (W/kg). The FCC requires wireless phones to
comply with a safety limit of 1.6 watts per kilogram (1.6 W/kg). The FCC exposure limit incorporates a
substantial margin of safety to give additional protection to the public and to account for any variations
in measurements.
SAR tests are conducted using standard operating positions accepted by the FCC with the phone
transmitting at its highest certified power level in all tested frequency bands. Although the SAR is
determined at the highest certified power level, the actual SAR level of the phone while operating can
be well below the maximum value. This is because the phone is designed to operate at multiple power
levels so as to use only the power required to reach the network. In general, the closer you are to a
wireless base station antenna, the lower the power output.
Before a new model phone is available for sale to the public, it must be tested and certified to the FCC
that it does not exceed the exposure limit established by the FCC. Tests for each model phone are
performed in positions and locations (e.g. at the ear and worn on the body) as required by the FCC. For
body worn operation, this phone has been tested and meets FCC RF exposure guidelines when used with
an accessory that contains no metal and that positions the handset a minimum of 1.5 cm from the body.
Use of other accessories may not ensure compliance with FCC RF exposure guidelines.
The FCC has granted an Equipment Authorization for this mobile phone with all reported SAR levels
evaluated as in compliance with the FCC RF exposure guidelines. The maximum SAR values for this
model phone as reported to the FCC are:
• Head: 1.44 W/Kg.
• Body-worn: 1.44 W/Kg.
SAR information on this and other model phones can be viewed on-line at www.fcc.gov/oet/fccid. To
find information that pertains to a particular model phone, this site uses the phone FCC ID number which
is usually printed somewhere on the case of the phone. Sometimes it may be necessary to remove the
battery pack to find the number. Once you have the FCC ID number (A3LSGHT719) for a particular phone,
follow the instructions on the website and it should provide values for typical or maximum SAR for a
particular phone. Additional product specific SAR information can also be obtained at www.fcc.gov/
