power level, the actual SAR level of the device 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.
The exposure standard for wireless devices employing a unit of
measurement is known as the Specific Absorption Rate, or
SAR. The SAR limit set by the FCC is 1.6 W/kg and 1.6 W/kg by
Industry Canada.
This device is in compliance with SAR for general population
/uncontrolled exposure limits in ANSI/IEEE C95.1-1992 and
Canada RSS 102 and had been tested in accordance with the
measurement methods and procedures specified in IEEE1528
and Canada RSS 102. This device has been tested and meets
the FCC and IC RF exposure guidelines when tested with the
device directly contacted to the body.
The FCC has granted an Equipment Authorization for this model
phone with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on this
model phone is on file with the FCC and can be found under the
Display Grant section of www.fcc.gov/oet/ea/fccid after searching
on FCC ID: SRQ-Z957.
For this device, the highest reported SAR value for usage against
the head is 0.78 W/kg, for usage near the body is 1.19 W/kg.
While there may be differences between the SAR levels of
various phones and at various positions, they all meet the
government requirement.
