Chapter 1 – Safety Information and
Product Description
The Multi-Tech iSMS is an intelligent Short Message Services (SMS) server that empowers businesses with the
ability to broadcast and receive SMS text messages with a click of a button. The ready-to-use solution simply
plugs into the Ethernet network and connects to the wireless network via an integrated quad-band GSM
modem. Now anyone on the network can broadcast messages allowing organizations to reach clients,
subscribers, members and prospects in real-time via SMS.
Safety Warnings
Ethernet Port Caution
The Ethernet port is not designed to be connected to a Public Switched Telecommunication Network
(PSTN).
Handling Precautions
All devices must be handled with certain precautions to avoid damage due to the accumulation of static
charge. Although input protection circuitry has been incorporated into the devices to minimize the effect
of this static build up, proper precautions should be taken to avoid exposure to electrostatic discharge
during handling and mounting.
Before servicing any part of the MultiModem iSMS system, read the instructions and cautions in this
section. This information explains how to work safely when servicing product. Observe the following safety
precautions when setting up the equipment:
•Follow all cautions, warnings, and instructions.
•Ensure that the voltages and frequency rating of the power receptacle match the electrical rating label
on the equipment.
•Never push or attach objects of any kind through openings inside the equipment. Object may touch
dangerous voltage points or short components, resulting in fire or electric shock.
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.

SF 100 SIM Card Installation
A SIM (Subscriber Identity Module) card is required in order for the MultiModem iSMS to operate on a
GPRS network. To install the SIM card:
1. Remove power from the unit before proceeding.
2. Use a small screwdriver to remove the screw closest to the outside edge of the MultiModem iSMS.
Then swing the SIM slot cover up and over to the left.
3. Insert the SIM card into the SIM card slot. The following graphic shows a partial front panel
illustrating the correct SIM card orientation.
4. Swing the cover back to its original placement and replace the screw. Reattach the power supply.

Chapter 1 – Safety Information and Product Description
Multi-Tech Systems, Inc. MultiModem® iSMS User Guide for Administrators 9
SF 400/800 SIM Card Installation
SIM (Subscriber Identity Module) cards are required for the MultiModem iSMS to operate on a GPRS
network. To install the SIM cards:
1. Power off the unit and unplug the power cord. Do not under any circumstances remove protective
power supply cover. Harmful voltages may be exposed if cover is removed, and can lead to electrical
shock and or death.
2. Electrostatic discharge (ESD) is the release of stored static electricity that can damage electrical
circuitry or components. Static electricity is often stored in your body, and discharged when you come
in contact with an object of a different potential.
Perform the procedure below (removal of chassis cover) described in this section only at an ESD
workstation using an antistatic wrist strap. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a metal ground screw (lug) next to
power switch of MultiModem iSMS chassis.
3. Use a small screwdriver to remove the six (6) screws on the back of the MultiModem iSMS as shown by
the red circles below. Then lift the top cover from the back of the unit and then slide towards the front
to remove.
4. Insert the SIM cards into the SIM card slots on the internal wireless modems. Each modem has a
graphic line depicting the correct SIM card orientation. These receptacles are highlighted by the two
red boxes in the illustration below (SF 800 model shown).
5. To re-attach the cover, start with the cover tilted up and align the “teeth” with the gaps between
those on the bottom of the chassis as shown by the red arrows in the illustration above.
6. Rotate the cover down and push towards the rear of the unit until it is flush.
7. Insert the six (6) screws back in to the unit and tighten.

Modem Numbering
When using the Web interface, the modem tabs correspond to the internal modems with the numbering
scheme shown below. The row of LEDs shows where the front of the unit is. Unpopulated modems should
be disabled as described in Network Setup.
Signal Strength
Signal Strength Command
To View Strength
For the SF 400/800 models without signal LEDs, signal strength can be viewed by using the following
AT command: AT+CSQ.This command is the default setting on the Network Setup > Cellular Modem
screen. This works for theSF 100 as well.
AT Command Response Example
+CSQ: xx, 99 (For xx, see the values chart below)
Signal Strength Reference Table
The following table lists the meaning of the xx values in the signal strength response and explains how
they correspond to the number of LEDs lit for signal strength.
AT+CSQ xx Values SF 100 Signal LED Bars Signal Strength
0 to 6 No light Very weak signal
7 to 14 1 Bar LED is lit Weak signal
15 to 23 1 Bar and 2 Bar LEDs are lit Stronger signal
24 to 31 1 Bar, 2 Bar, 3 Bar LEDs are lit Strongest signal
