Radio Frequency (RF) Energy
This model phone meets the government’s requirements
for exposure to radio waves.
This 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:
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.
The highest SAR value for the model phone as reported
to the FCC when tested for use at the ear is 1.04 W/kg
and when worn on the body, as described in this user
guide, is 1.37 W/kg (Body-worn measurements differ
among phone models, depending upon available
enhancements 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.
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/ea/fccid/ after
searching on
FCC ID: Q78-Z990.
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 guidelines. If you do not use a
body-worn accessory and are not holding the phone at
the ear, position the handset a minimum of 1.5 cm from
your body when the phone is switched on.
FCC Compliance
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
* 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.
