Introduction
This guide shows you how to setup your Multi-Tech wireless
MultiModem. For detailed information, product specification,
troubleshooting tips, and warranty repair policies, see the
User Guide, available on the MultiModem CD accompanying
your wireless modem.
General Safety
The modem is designed and intended to be used in either
fixed or mobile applications. In the “Fixed” application, the
device is physically secured at one location and not easily
moved to another location. In the “Mobile” application, the
device may be regularly moved to different locations.
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. Such uses are strictly
prohibited.
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 telephone 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 where blasting operations are in
progress.
•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.
•Operation of the MultiModem in the vicinity of other
electronic equipment may cause interference if the
equipment is inadequately protected. Observe any warning
signs and manufacturers’ recommendations.
InstallationInstructionsforHazardousLocations
•The modems are open devices intended for installation in
an ultimate enclosure suitable for the intended application.
• All wiring must be in accordance with wiring methods of
Article 501.4B of the National Electrical Code, NFPA 70 or
as specified in section 18-152 of the Canadian Electrical
Code for installation within Canada and in accordance
with the authority having jurisdiction.
• “WARNING - EXPLOSION HAZARD - Substitution of
Components may Impair Suitability for Class I Division 2”.

VehicleSafety
•Do not use your MultiModem while driving.
•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.
•The use of an alert device to operate a vehicle’s lights or
horn on public roads is not permitted.

MaintenanceoftheWirelessMultiModem
Your Wireless MultiModem is the product of advanced
engineering, design and craftsmanship and should be
treated with care. The suggestions below will help you to
enjoy this product for many years.
•Do not expose the MultiModem to any extreme environment
where the temperature or humidity is high.
•Do not attempt to disassemble the MultiModem. There are
no user serviceable parts inside.
•Do not expose the MultiModem to water, rain or spilled
beverages. It is not waterproof.
•Do not abuse your MultiModem by dropping, knocking, or
violently shaking it. Rough handling can damage it.
•Do not place the MultiModem alongside computer discs,
credit or travel cards, or other magnetic media. The
information contained on discs or cards may be affected by
the phone.
•The use of accessories not authorized by Multi-Tech or not
compliant with Multi-Tech’s accessory specifications may
invalidate the warranty of the MultiModem.
•In the unlikely event of a fault in the MultiModem, contact

with two mounting screws. Drill the mounting holes at the
desired location separated by 125mm (4 -15/16 inches)
center-to-center.

Identity Module) to operate on a GSM network. To install the
card, do the following:
1. Using your fingernail or a small screwdriver, pry off the
SIM cover.
2. Insert the SIM card into the holder.

Note: For automotive applications: according to the type of
application, you can use permanent “+” or key-switched “+”.
Connect the power supply to its source (for example, in a
mobile situation, to the vehicle’s DC fuse/terminal block).
Activate the DC power supply.
AT Commands
A complete set of AT command definitions can be found in
the AT Command Reference Guides (one for GPRS and one
for CDMA). These guides are available on the Multi-Tech
web site or on the MultiModem CD.
Phone Number for the Wireless Modem
•Every wireless modem will have its own unique phone number.
•The wireless modem’s phone number may simply be told to
the subscriber or be on the SIM or both. Wireless provider
implementations may vary.
Network Access
For GSM-without-GPRS, a circuit-switched data connection
is used. The user can set up DUN to make a conventional
V.32 modem connection to any terminating modem at the
other end. The phone number specified in DUN can be one
supplied by the wireless service provider or another phone
number related to a different dialup modem service (e.g., a
dialup modem service phone number from any commercial
or private dialup network).
For GSM-with-GPRS, a single DUN number is generally
used by all of a wireless provider’s subscribers throughout its
area of coverage (regional, nationwide, continental, etc.).
Rather than being a literal phone directory number, as in
conventional DUN, this is a code that gives the modem
Internet access.

For CDMA point to point data, a circuit-switched data
connection is used. The user can set up DUN to make a
conventional V.32 modem connection to any terminating
modem at the other end. The phone number specified in
DUN can be one supplied by the wireless service provider or
another phone number related to a different dialup modem
service (e.g., a dialup modem service phone number from
any commercial or private dialup network).
For CDMA 1x data, a single DUN number is generally used
by all of a wireless provider’s subscribers throughout its area
of coverage (regional, nationwide, continental, etc.). Rather
than being a literal phone directory number, as in
conventional DUN, this is a code that gives the modem
Internet access.
Mobile PhoneTools
For initial configuration of your wireless device, Multi-Tech
offers a Windows based mobile PhoneTools application. To
load mobile PhoneTools, click on the mobile PhoneTools
icon on the MultiModemCD and follow the on-screen
prompts.
DirectModemInstallation
To install the Wireless MultiModem directly into the
computer’s Windows OS so it is independent of the mobile
Phonetools program, use the “Add Modem” command or
equivalent for your OS. During this installation, you will need
to browse to the MultiModem’s INF file (using the “Have Disk”
option in the installation process). This INF file is in the root
directory of the MultiModem CD.
