Radio Frequency (Rf) Energy - Zte AT&T Z222 User Manual

Radio Frequency (RF) Energy

This model device meets the government's requirements for exposure to radio
waves .
This device 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 devices employs a unit of measurement
known as the Specific Absorption Rate or 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 device 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 device while operating can be well below the
maximum value . This is because the device 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 0 . 6 22 W/kg and when worn on the body, as described in this
user guide, is 0 . 6 67 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 devices and at
various positions, they all meet the government requirement .
The FCC has granted an Equipment Authorization for this model device with
all reported SAR levels evaluated as in compliance with the FCC RF exposure
guidelines . SAR information on this model device is on file with the FCC and can
be found under the Display Grant section of http://www . f cc . g ov/oet/fccid after

• FCC ID: Q78-Z222 .
• 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 guideline .
* 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 .
