While there may be differences between the SAR levels
of various devices and at various positions, they all
meet the government requirement.
The FCC has granted an Equipment Authorization for
this model device with all reported SAR levels evaluated
as in compliance with the FCC RF exposure guidelines.
SAR information on this model device is on file with the
FCC and can be found under the Display Grant section
of http://www.fcc.gov/oet/fccid after searching on:
FCC ID: Q78-Z221.
• For body worn operation, this phone has been tested
and meets the FCC RF exposure guidelines for
use with an accessory that contains no metal and
positions the handset a minimum of 1.5 cm from the
body. Use of other enhancements may not ensure
compliance with FCC RF exposure guideline.
This model device meets the government’s requirements
for exposure to radio waves.
This device is designed and manufactured not to exceed
the emission limits for exposure to radio frequency (RF)
energy set by the Federal Communications Commission
of the U.S. Government.
The exposure standard for wireless devices employs a
unit of measurement known as the Specific Absorption
Rate or SAR. The SAR limit set by the FCC is 1.6W/kg.*
Tests for SAR are conducted using standard operating
positions accepted by the FCC with the device
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 device while operating can be well below the
maximum value. This is because the device 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 highest SAR value for the model phone as reported
to the FCC when tested for use at the ear is 0.622 W/
kg and when worn on the body, as described in this
user guide, is 0.667 W/kg. (Body-worn measurements
differ among phone models, depending upon available
accessories and FCC requirements.)
* In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram
of tissue. The standard incorporates a substantial margin of safety to give additional protection for the public and to account for any
variations in measurements.
