Multi-Tech Systems, Inc. Quick Start Guide 3
Introduction
This guide shows you how to set up your Multi-Tech wireless
MultiModem. For detailed information, product specifications,
troubleshooting tips, and more, see the User Guide, available on the
MultiModem CD accompanying your wireless modem.
General Safety
The modem is designed for and intended to be used in fixed and mobile
applications. “Fixed” means that the device is physically secured at one
location and is not able to be easily moved to another location. In a
“Mobile” application, the device may be moved regularly from one
location to another.
Caution: Maintain a separation distance of at least 20 cm (8 inches)
between the transmitter’s antenna and the body of the user or nearby
persons. The modem is not designed for, nor intended to be, used in
applications within 20 cm (8 inches) of the body of the user.
RF Interference Issues
Avoid possible radio frequency (RF) interference by carefully following
the safety guidelines below.
•Switch OFF the MultiModem when in an aircraft. The use of cellular
telephones in aircraft is illegal. It may endanger the operation of the
aircraft and/or disrupt the cellular network. Failure to observe this
instruction may lead to suspension or denial of cellular services to
the offender, legal action, or both.
•Switch OFF the MultiModem in the vicinity of gasoline or diesel-fuel
pumps or before filling a vehicle with fuel.
•Switch OFF the MultiModem in hospitals and any other place where
medical equipment may be in use.
•Respect restrictions on the use of radio equipment in fuel depots,
chemical plants, or in areas of blasting operations.
•There may be a hazard associated with the operation of your
MultiModem in the vicinity of inadequately protected personal
medical devices such as hearing aids and pacemakers. Consult the
manufacturers of the medical device to determine if it is adequately
protected.

equipment may cause interference if the equipment is
inadequately protected. Observe any warning signs and
manufacturers’ recommendations.
Vehicle Safety

•Respect national regulations on the use of cellular telephones in
vehicles. Road safety always comes first.
•If incorrectly installed in a vehicle, the operation of MultiModem
telephone could interfere with the correct functioning of vehicle
electronics. To avoid such problems, be sure that the installation
has been performed by qualified personnel. Verification of the
protection of vehicle electronics should be part of the installation.

phone number may simply be given to you by your wireless service
provider or it may be on the SIM card or both. Wireless provider
implementations may vary.

The wireless modem requires a SIM card (Subscriber Identity Module) to
operate on a GSM/GPRS network. To install the SIM card:
1. Using your fingernail or small screwdriver, pry off the SIM cover.
2. Insert the SIM card into the SIM card slot. The following graphic
illustrates the correct SIM card orientation.

Installing the MultiModem USB Driver
Compatibility: The wireless modem is compatible with Windows Vista,
XP, 2003, 2000, and Linux.
Windows: Place the MultiModem CD into the PC’s CD-ROM drive and
plug the USB cable into the PC. The Add New Hardware Wizard will
display. Please follow the installation prompts. For detailed driver
installation directions, see the User Guide.
Linux: Under the Linux directory on the MultiModem CD, you will find
the Linux driver and a Readme file. Refer to the Readme file for the
driver file and installation guide for your distribution/version of Linux.
Note: If your model did not include a CD, you can download the drivers
from the Multi-Tech Web site.
Changing the GPRS Band
All MultiModem GPRS-F4 wireless modems support quad band. The
modems are available in two build options: one defaulting to
850/1900MHz and one defaulting to 900/1800MHz.
If for any reason, such as changing the geographical area in which you
use your modem, you want to change the band, you can accomplish it
by using the +WMBS AT Command.
Changing the GPRS Band for RS-232 and USB Models
Use a terminal application such as HyperTerminal to enter the AT
Command: AT+WMBS=4,0.
For accessing HyperTerminal, see the User Guide for directions.
AT Commands
AT commands can be used to operate, configure, and query your
modem. The AT Command Reference Guides for GPRS are included on
the MultiModem CD and on the Multi-Tech Web site.
Internet Access
See the User Guide for Internet access directions.
