Safety Precautions
1) Data transmission and reception cannot be guaranteed because of the nature of
Wireless communications.Data can be delayed, corrupted or lost during transmission.
Even though it is quite rare that significant data delay or loss occurs if the USB device
is used in a normal manner,this USB device should not be used in cases that data
transmission or another party,including but not limited to personal injury,death or loss
of personal property. Franklin bears no responsibility for damages or losses of any kind
resulting from delays,or for failure of the USB device to transmit or receive such data.
2) Do not use this USB device in areas where blasting is in progress,where explosive
Atmospheres may be present,near medical equipment,life support equipment which

SPECIFIC ABSORPTION RATES (SAR)
Maximum: SAR 1.030 W/kg CDMA835 Body
SAR 1.160 W/kg PCS1900 Body, SAR 0.424 W/kg Wimax Body
THIS MODEL MEETS THE GOVERNMANET’S REQUIREMENTS FOR EXPOSURE TO
RADIO WAVES.
Your wireless usb 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 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 at the when worn on the body, as
described in this user guide, is 1.160 W/Kg. (Body-worn measurements differ among modem
models, depending upon available accessories and FCC requirements). 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: TARCMU-300.
SAFETY INFORMATION FOR RF EXPOSURE
Body worn operation
SAR compliance has been established in the laptop computer(s) with Horizontal slot
configurations, and can be used in laptop computers with substantially similar physical
dimensions, construction, and electrical and RF characteristics.
Safety Information
SAFETY INFORMATION FOR FIXED WIRELESS TERMINALS POTENTIALLY EXPLOSIVE
ATMOSPHERES
Turn your wireless 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 you wireless modem. Turn
your wireless modem OFF in health c are 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 wireless modem is in use. Do not move the antenna close to, or
couching any exposed part of the body when making a conect.
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.
