• one fused power cable
• one Quick Start Guide
Bundled Package
• All Basic Package items except the fused power cable, plus
• one RS232 15-to-9 pin cable
• four adhesive-backed rubber feet for table-top mounting
• one antenna
• one universal power supply with power cord
• one product CD
Interfaces
The Wireless MultiModem has several interfaces:
• LED function indicating operating status

• Serial and control link (via 15 pins SUB D)
• Power supply (via 2.5mm miniature power jack)
Parts to be Supplied by End User
• Mounting screws (screw shaft diameter = .17” max.)
• Antenna
• The Wireless MultiModem is shipped with an antenna suited for it. However, if the antenna supplied does not
meet your application requirements (for size, shape, mounting style, etc.), you must supply an antenna
yourself. In general, the antenna used must be both of the correct frequency and of a style appropriate to
the application. See the Antenna/RF Specifications section below.

AT Command Info
AT commands for the CDMA wireless modem are published in a separate Reference Guide included on
the product CD and posted on the Multi-Tech web site.
Phone Number for the Wireless Modem
Every wireless modem will have its own unique phone number.
Network Access
The network access arrangements to be specified in Windows Dial-Up Networking (of the computer that
the wireless modem is serving) will vary according to the type of wireless service used.
• For point to point data, a circuit-switched data connection is used. The user can set up DUN to make
a conventional V.32bis 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.
Features
• CDMA2000 1xRTT operation
• Dual-band 800/1900 CDMA
• 800 MHz with R-UIM support

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 your MultiModem CD and follow the onscreen prompts.
Direct Modem Installation
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 Product CD.
Verifying Signal Strength
The Wireless MultiModem establishes a call if the signal is sufficiently strong. To verify the signal
strength, do the following:
1. Using the Hyperterminal program at the computer to which the Wireless MultiModem is connected, type
the AT command AT+CSQ. A value for the received signal strength will be returned.
2. Verify the result with the following chart:
Signal Strength Verification
Value of signal strength
(AT+CSQ response) (RSSI)
10 - 31 Sufficient
0 - 9 Weak or Insufficient
99 Insufficient
Signal strength
Verifying Network Registration
In this procedure, you will verify that the Wireless MultiModem has been registered on the wireless network.
To do so, you will use the common communications program Hyperterminal.
1. Using the Hyperterminal program at the computer to which the Wireless MultiModem is connected, type
the AT command AT+CREG?
A value for the modem’s network registration status will be returned.
2. Verify the result with the following chart:
Network Registration Verification
Value Network Registration Status
0, 1 Yes
0, 5 Yes
(registered roaming)
Note: If the modem is not registered, perform the procedure for Verifying Signal Strength to determine the
strength of the received signal.

Chapter 4 - Safety
Chapter 4: Safety
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. “Mobile”
means that the device is designed to be used in other than fixed locations
and generally in such a way that a separation distance of at least 20 cm (8
inches) is normally maintained between the transmitter’s antenna and the
body of the user or nearby persons. The Modem is not designed for or
intended to be used in portable applications (within 20 cm. or 8 in. of the
body of the user) and such uses are strictly prohibited.
It is important to follow any special regulations regarding the use of radio equipment due in particular to the
possibility of radio frequency, RF, interference. Please follow the safety advice given below carefully.
• Switch OFF your Wireless MultiModem when in an aircraft. The use of cellular telephones in an aircraft may
endanger the operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe this
instruction may lead to suspension or denial of cellular telephone services to the offender, or legal action or
both.
• Switch OFF your Wireless MultiModem when around gasoline or diesel-fuel pumps and before filling your
vehicle with fuel.
• Switch OFF your Wireless 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 Wireless MultiModem close to 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 your Wireless MultiModem close to other electronic equipment may also cause interference if
the equipment is inadequately protected. Observe any warning signs and manufacturers’ recommendations.
Vehicle Safety
• Do not use your Wireless MultiModem while driving, unless equipped with a correctly installed vehicle kit
allowing ‘Hands-Free’ Operation.
• 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 Wireless 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.
Multi-Tech Systems, Inc. MultiModem CDMA User Guide 20
Chapter 4 - Safety
