1 USB Modem Introduction

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
• 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
• 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
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
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 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:
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.
