FCC Health and safety in formation

Radio Frequency (RF) Energy

This model USB Modem meets t he go ver nmen t’ s requ irem ents for ex po sure
to radio wave s.
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 Mode m employs a unit of measu rement
known as the Specific Absorption Rate, or SAR. The SAR limit set by the
FCC is 1.6W/ kg. *Tests for SAR are conduc ted using stand ard 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 determ ined at th e h igh est cert if ied p ow er lev e l, the a ct ua l S AR 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 u se only th e poser r equired to reac h the netwo rk. 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

0.823 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 vario us positions, they all mee t the gover nment requi rement.
The FCC has gran ted an Equ ipmen t Auth oriz ation for this model phone with
all reported SAR l evels eval uated as in comp liance with th e FCC RF exposur e
guidelines. SAR informat ion on this mode l phone is on fi le with the FCC and
can be found under the Display Grant section of
http://www.fcc.gov/oet/fccid after search ing o n

FCC ID: KA2WM152A3.

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 interfere nce that may cau s e undes ired opera t ion.

Caution: Changes or modifications not expressly approved by the
manufacturer could void the user’s authority to operate the equipment.

NOTE: This equipm e nt h as b ee n tested and fou nd to comply with the limits
for a Class B d igital device, p ursuant to part 15 of the FCC Rules. These lim its
are designed to provide reasonable protection against harmful interference
in a residential in stallation. This equ ipment g enerat es, uses an d can rad iate
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 harmf ul in t erfer en c e to
radio or television reception, which can be determined by turning the

8

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.
