Radio Frequency (RF) Signals
THIS MODEL PHONE MEETS THE U.S.
GOVERNMENT'S REQUIREMENTS FOR
EXPOSURE TO RADIO WAVES.
Your wireless phone contains a radio transmitter
and receiver. Your phone 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 exposure standard for wireless mobile
phones employs a unit of measurement known
as the Specific Absorption Rate (SAR). The
SAR limit set by the FCC is 1.6 W/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 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 U.S. government-adopted
requirement for safe exposure. The tests are
performed on position and locations (for
example, at the ear and worn on the body) as
required by FCC for each model. The highest
SAR value for this model phone as reported to
the FCC when tested for use at the ear is
0.66 W/kg, and when worn on the body, is
1.06 W/kg. (Body-worn measurements differ
among phone models, depending upon
available accessories and FCC requirements).
While there may be differences between the
SAR levels of various phones and at various
positions, they all meet the U.S. government
requirement.
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 at
GenericSearch.cfm after search on FCC ID A98-
QOE9653.
For body worn operation, this phone has been
tested and meets the FCC RF exposure
guidelines when used with an accessory
designated for this product or when used with
an accessory that contains no metal and that
positions the handset a minimum of 1.0 cm
from the body.
