1.2 Warning and Notice
To the owner

 Some electronic devices are susceptible to electromagnetic

interference sent by modem if inadequately shielded, such as
electronic system of vehicles. Please consult the
manufacturer of the device before using the modem if
necessary.

 Operating of laptop and desktop PC and 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

5

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 explosive products being
processed. Therefore, turn off your modem if required.

 Don’t touch the inner antenna area if not necessary.

Otherwise it will affect your modem’s performance.

 Store the modem out of the reach of little children. The

modem may cause injury if used as a toy.

Modem

 Please use original accessories or accessories that are

authorized. Using any unauthorized accessories may affect
your modem’s performance, and violate related national
regulations about telecom terminals.

 Avoid using the modem near metallic structure device or

establishment that can emit electromagnet wave. Otherwise it
may influence receiving signals.

 The modem is non-waterproof type, please keep it dry and

store in shady and cool place.

 Don’t use the modem immediately after a sudden

temperature change. In such case, it will produce dew inside
and outside the modem, so don’t use it until it becomes dry.

Otherwise it will lead to destruct damage.

 No dismantling by non-professional and only qualified

maintainer can undertake repair work.

1.3 Applicability Scope

ZTE USB Modem supports the present mainstream types of
laptops and desktop PCs, such as HP, IBM, Toshiba, Lenovo,
Dell, Sony, etc.

1.4 Radio Frequency (RF) Energy

6

This model device meets the government’s requirements for

exposure to radio waves.
This device 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 devices employs a unit of
measurement known as the Specific Absorption Rate, or SAR.
The SAR limit set by the FCC is 1.6W/kg. The highest SAR
value reported to the FCC for this device type was compliant
with this limit at 5mm. *Tests for SAR are conducted using
standard operating positions accepted by the FCC with the
device 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
device while operating can be well below the maximum value.
This is because the device 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 device as reported to the
FCC when worn on the body, as described in this user guide, is

1.180 W/kg (Body-worn measurements differ among device
models, depending upon available enhancements and FCC
requirements.)
While there may be differences between the SAR levels of
various devices and at various positions, they all meet the
government requirement.
The FCC has granted an Equipment Authorization for this model
device with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on this
model device 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: Q78-004Z.

7

1.5 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.
