8.7 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 poser 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 worn on the body, as described
in this user guide, is 1.04 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-ZTEMF91
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 the positions the handset a minimum of 1 cm from the body.
Use of other enhancements may not ensure compliance with FCC RF exposure guidelines. If you do no t
use a body-worn accessory and are not holding the phone at the ear, position the handset a minimum of 1
cm from your body when the phone is switched on.
