SAR INFORMATION

THIS MODEL MODEM MEETS THE GOVERNMENT’S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.

Your wireless modem is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission
limits for exposure to radiofrequency (RF) energy set by the Federal Communications Commission of the U.S.
Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the
general population. The guidelines are based on standards that were developed by independent scientific
organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial
safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for
wireless mobile modem employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR
limit set by the FCC is 1.6 W/kg. * Tests for SAR are conducted with the 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 modem while operating can be well below the maximum value. This is because the modem 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. Before a modem model is available
for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the
government adopted requirement for safe exposure. The tests are performed in positions and locations (e.g., at the
ear and worn on the body) as required by the FCC for each model. The highest SAR value for this model modem
when tested for use near the body, as described in this user guide, is 1.38 W/Kg. While there may be differences
between the SAR levels of various modems and at various positions, they all meet the government requirement for
safe exposure. The FCC has granted an Equipment Authorization for this model modem with all reported SAR levels
evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model 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: RB2-U772. Additional information on Specific Absorption Rates (SAR) can be found on the Cellular
Telecommunications Industry Association (CTIA) web-site at http://www.wow-com.com. * In the United States and
Canada, the SAR limit for mobile modems used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue.
The standard incorporates a substantial margin of safety to give additional protection for the public and to account for
any variations in measurements.

SAFETY INFORMATION

SAFETY INFORMATION FOR FIXED WIRELESS TERMINALS POTENTIALLY EXPLOSIVE ATMOSPHERES
Turn your modem OFF when in any area with a potentially explosive atmosphere and obey all signs and instructions.
Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.

INTERFERENCE TO MEDICAL DIVICES

Certain electronic equipment may be shielded against RF signal from your wireless modem (pacemakers, Hearing
Aids, and so on). Turn your modem OFF in health care facilities when any regulations posted in these areas instruct
you to do so. RF signals may affect improperly installed or inadequately shielded electronic system in motor vehicles.

EXPOSURE TO RF ENERGY

Use only the supplied or an approved replacement antenna. Do not touch the antenna unnecessarily when the
modem is in use. Do not move the antenna close to, or couching any exposed part of the body when making a call.

NEAR BODY OPERATION

This device was tested for typical near body operations with the back of the modem kept 0.5 cm from the body. To
maintain compliance with FCC RF exposure requirements, it must have a minimum distance including the antenna of

0.5 cm from the body during normal operation

U.S.A.

U.S. FEDERAL COMMUNICATIONS COMMISSION RADIO FREQUENCY INTERFERENCE STATEMENT
INFORMATION TO THE USER

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

27

and used in accordance with the instructions, may cause harmful Interference to radio communications. However,

Warning: Exposure to Radio Frequency Radiation The radiated
output power of this device is far below the FCC radio frequency
exposure limits. Nevertheless, the device should be used in such a
manner that the potential for human contact during normal operation
is minimized. In order to avoid the possibility of exceeding the FCC
radio frequency exposure limits, human proximity to the antenna
should not be less than 20 cm during normal operation as a plug-in­wall-adaptor access point as 3G/4G and Wi-Fi transmit
simultaneously in this configuration.

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 of a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV
technician for assistance.

Changes or modification not expressly approved by the party responsible for Compliance could void the user’s
authority to operate the equipment. Connecting of peripherals requires the use of grounded shielded signal cables.

FCC Compliance Information

This device complies with Part 15 of 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.

 LAN: Local Area Network. A type of network that lets a group of computers, all in close

proximity (such as inside an office building), communicate with one another. It does not use
common carrier circuits though it can have gateways or bridges to other public or private
networks.

 MAC Address: Media Access Control. A number that uniquely identifies each network

hardware device. MAC addresses are 12-digit hexadecimal numbers. This is also known as
the physical or hardware address.

 Mbps: Megabits per second. The rate of data flow.
 MSID: Mobile Station Identifier. A number for a mobile phone that identifies that phone to

the network. These numbers are carrier specific.

 Network Technology: The technology on which a particular network provider’s system is

built; such as CDMA or EVDO.
