CERTIFICATION INFORMATION (SAR)
THIS MODEL PHONE MEETS THE GOVERNMENT'S REQUIREMENTS FOR EXPOSURE
TO RADIO WAVES.
Your wireless phone is a radio transmitter and receiver. It 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. These limits are part of comprehensive guidelines and establish
permitted levels of RF energy for the general population. The guidelines are based
on standards that were developed by independent scientific organizations through
periodic and thorough evaluation of scientific studies. The standards include a
substantial safety margin designed to assure the safety of all persons, regardless of
age and health.
The exposure standard for wireless mobile phones 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 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 phone model is available for sale to the public, it must be tested and
certified to the FCC that it does not exceed the limit established by the
government-adopted requirement for safe exposure. The tests are performed in
positions and locations (for example, at the ear and worn on the body) as required
by the FCC for each model.
The highest SAR value for this model phone as reported to the FCC:
When tested for use at the ear -
FCCID # PPIRH-19 is 0.72 W/kg
FCCID # PPIRH-50 is 0.98 W/kg
When worn on the body, as described in this user guide:
FCCID # PPIRH-19 is 0.58 W/kg
FCCID # PPIRH-50 is 0.71 W/kg
Body-worn measurements differ among phone models, depending upon available
enhancements and FCC requirements.
