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 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 is 1.13 W/kg (Body-worn measurements)
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: Q78-MF656A
For body worn operation, this USB modem has been tested and meets
the FCC RF exposure guidelines and the positions the modem with a
minimum of 0.5 cm from the body.
FCC Compliance (only Part 15B)
This device complies with part 15 of the FCC Rules. Operation is
subject to the condition that this device does not cause harmful
interference.
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.
To the owner
• Some electronic devices are susceptible to electromagnetic interference
sent by modem if inadequately shielded, such as the electronic system of
vehicles. Please consult the manufacturer of the device before using the
modem if necessary.
• Operating of laptop and desktop PCs and the modem may interfere with
medical devices like hearing aids and pacemakers. Please always keep
them more than 20 centimeters away from such medical devices when they
are turned on. Turn the modem off if necessary. Consult a physician or the
manufacturer of the medical device before using the modem.
• Be aware of the usage limitation when using a modem at places such as oil
warehouses or chemical factories, where there are explosive gases or
