Portable Radio Product Operation and EME Exposure
ALL MODELS WITH FCC ID AZ489FT5844 MEET 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 radiofrequency (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.
1
Tests for SAR are conducted using standard
operating positions reviewed 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 is does not
exceed the limit established by the government-adopted
requirement for safe exposure. The tests are performed in
positions and locations (e.g., at the ear and worn on the
body) as required by the FCC for each model. The highest
SAR value for this model phone when tested for use at the
ear is 1.05 W/kg and when tested on the body, as
described in this user guide, is 1.15 W/kg during packet
data transmission. (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
government requirement for safe exposure.
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
http://www.fcc.gov/oet/fccid after searching on FCC ID
AZ489FT5844.
Additional information on Specific Absorption Rates (SAR)

Association (CTIA) web-site at http://www.wow-com.com.

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.

FCC-accepted Motorola testing protocol, assessment
procedure, and measurement uncertainty range for this
product.
