1 USB Modem Introduction
1.1 Introduction
Thank you for choosing the ZTE MF668 USB modem. Please read this
manual carefully and keep it for future reference.
The pictures, symbols and contents in this manual are for reference
only. They are correct at the time of publication but might not be completely
identical with your modem. We operate a policy of continuous
development. We reserve the right to update the technical specifications
in this document at any time without prior notice.
The HSPA+ modem is a multi-mode 3G high speed modem suitable for
GSM/GPRS/WCDMA/EDGE/HSDPA/HSPA+ networks. It uses the USB 2.
0 standard interface for easy connection to any laptop or desktop
computer. It is compatible with 2G and 3G mobile networks, allowing
connection with wireless data and SMS services to give you high speed
data access wherever you are.
1.2 Safety Warning and Notice
To the owner
• Some electronic devices are susceptible to electromagnetic
interference. The modem is a transmitting device and may cause
interference to sensitive electronic equipment such as audio systems,
vehicle systems and medical equipment. Please consult the
manufacturer of the other device before using the modem.
• Operating of a laptop or desktop computer with the modem may
interfere with medical devices like hearing aids and pacemakers.
Please keep the modem more than 20 centimetres away from such
medical devices. Turn the modem off if necessary. Consult a physician

or the manufacturer of the medical device before using the modem
near such devices.
• Be aware of the regulations when using the modem at places such
as oil warehouses or chemical factories, where there are explosive
gases or explosive products being processed. Turn off your modem
as instructed.
• Don’t touch the antenna area unnecessarily while connected. This
can affect your modem performance and reduce the signal quality.
• Store the modem out of the reach of children. The modem may cause
injury or get damaged.
• The modem contains sensitive electronic circuitry. Do not expose the
modem to any liquids, high temperatures or shock.
• Only use original accessories or accessories that are authorized by
the manufacturer. Using unauthorized accessories may affect your
modem’s performance, damage your modem and violate related national
regulations.
• Avoid using the modem in areas that emit electromagnetic waves, or
in enclosed metallic structures (eg. elevators).
• The modem is not waterproof. Please keep it dry and store it in a cool,
dry place.
• Don’t use the modem immediately after a sudden temperature change
(eg. from an air conditioned environment to high temperature and
humidity outside). In such cases there could be condensing moisture
inside the modem which can cause internal damage. Unplug the modem
and leave it for 30 minutes before use.
• Always handle the modem with care. Be careful not to drop or bend
the modem.
• There are no user serviceable parts inside the modem. Unauthorised

dismantling or repair of the modem will void the warranty.
1.3 RF Safety Information
The USB Wireless modem is a transmitting device with similar output
power to a mobile phone. It uses an internal antenna to connect to the
mobile network. To get the best performance from your device, do not
cover or shield the device in any way as this will lead to increased
output power. Always leave a clear space around the device to allow
the transmit and receive signals to propagate. It is not intended to be
used as a handheld or body worn device but the SAR tests have been
completed and exceed Canadian and US regulatory requirements.
Radio Frequency Energy
Your handset is a low-power radio transmitter and receiver. When
switched on it intermittently transmits radio frequency (RF) energy (radio
waves). The transmit power level is optimized for best performance and
automatically reduces when there is good quality reception. Maximum
power is only used at the edge of network coverage so under most
circumstances the power output is very low. Under poor network conditions the phone will transmit at a higher power, may get hot and will
have a significantly shorter battery life.
Declaration of Conformity
THIS MODEL PHONE MEETS THE GOVERNMENT’S REQUIREMENTS FOR
EXPOSURE TO RADIO WA VES.
Your wireless phone is a radio transmitter and receiver. It 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. 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 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 phones 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 phone 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 phone while operating can be well below the
maximum value. This is because the phone 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 wireless base station antenna,
the lower the power output.
Before a phone model is available for sale to the public in 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 as required by the
FCC for each model.
The highest SAR values, as reported to the FCC for this model phone
when worn on the body, are 0.959W/kg for Cellular 850MHz and 1.02W/
kg for PCS 1900MHz. (Body-worn measurements differ among phone
models, depending upon available accessories and FCC requirements.)
While there may be differences between the SAR levels of various
phones and at various positions, they all meet the government requirement.
For body-worn operation, this model has been tested and meets the FCC
USB Modem Introduction

RF exposure guidelines when used with the ZTE accessories supplied or
designated for this product. Use of other accessories may not ensure
compliance with FCC RF exposure guidelines. While there may be differences between the SAR levels of various phones and at various positions.
In all cases, products are designed to be within the guidelines.
FCC has granted an Equipment Authorization for this model phone with all
reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. Additional information on Specific Absorption Rates (SAR)
can be found on the Cellular Telecommunications & Internet Association
(CTIA) web site: http://www.phonefacts.net or the Canadian Wireless
Telecommunications Association (CWTA) web site: http://www.cwta.ca.
In the United States and Canada, the SAR limit for mobile phones used by
the public is 1.6watts/kg (w/kg) average 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.
