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 1.6W/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 device as reported to the FCC when tested for use at the ear is 0.61
W/kg and when worn on the body, as described in this user guide, is
0.98
W/kg. (Body-worn
measurements differ among device models, depending upon available enhancements 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.fcc.gov/oet/fccid after searching on:
•
FCC ID:
Q78-Z222
.
•
For body worn operation, this modem 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.
