FCC Health and safety information
Radio Frequency (RF) Energy
This model USB Modem meets the government’s requirements for exposure
to radio waves.
This USB Modem 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 USB Modem 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

7
positions accepted by the FCC with the USB Modem 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 USB modem while operating can be well below the maximum value.
This is because the USB modem 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 USB Modem as reported to the FCC is
1.14 W/kg on the body with 5mm separation between USB modem to SAR
phantom.
While there may be differences between the SAR levels of various USB
Modem 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/fccid after searching on
FCC ID: Q78-MF112.
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.
Caution: Changes or modifications not expressly approved by the
manufacturer could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to

8
radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
