Health and safety information
Radio Frequency (RF) Energy
This model USB 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 wireless mobile USB modems 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 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 when
tested for use at worn on the body is 0.831 W/kg (Body-worn measurements differ
among USB modem models, depending upon available enhancements and FCC
requirements.)
While there may be differences between the SAR levels of various USB modems and
at various positions, they all meet the government requirement.
The FCC has granted an Equipment Authorization for this model USB modem with all
reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines.
SAR information on this model USB modem 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: KA2WM158B1
For body worn operation, this USB modem has been tested and meets the FCC RF

6
exposure guidelines for use a minimum of 0.5 cm from the body.
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
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:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
—Consult the dealer or an experienced radio/ TV technician for help.
