Warning and Notice
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 explosive products being processed. Turn off your modem
if required.
• The use of electronic transmitting devices is forbidden in aircrafts, at petrol stations and in hospitals.
Please observe and obey all warning signs and switch off your modem in these conditions.
• Do not 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.
• Do not touch the metallic parts of the modem so as to avoid a burn, when the modem is working.
Using your USB 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 or inside metallic structures or establishments that can emit
electromagnetic waves. Otherwise it may influence signal reception.
• The modem is not waterproof. Please keep it dry and store in a shady and cool place.
• Do not 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.
• Handle the modem carefully. Do not drop, bend or strike it. Otherwise the modem will be damaged.
• No dismantling by non-professionals and only qualified technicians can undertake repair work.
• Operating temperature range of -10℃ ~ +55℃ and humidity range of 5% ~ 95% are recommended.
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.
4 Con fid e nt ia l a nd Propr ie t a ry I nform at ion of ZTE CORPORATI ON
—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.
Radio Frequency (RF) Energy
This 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 device 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 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. SAR compliance has been established
in the host product(s) (laptop computers), tested at 5mm separation distance to the human body,
and tested with USB slot configurations including Horizontal-UP, Horizontal-Down,
Vertical-Front, Vertical-Back. This device can be used in host product(s) with substantially
similar physical dimensions, construction, and electrical and RF characteristics. The highest SAR
value, tested per FCC RF exposure guidelines for USB dongle, as described in this user guide, is
1.17 W/kg. The FCC has granted an Equipment Authorization for this device with all reported
SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information
on this device is on file with the FCC and can be found under the Display Grant section of
www.fcc.gov/oet/ea/fccid after searching on FCC ID: Q78-MF820B.
