Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be guaranteed.
Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of
data are rare when wireless devices such as the modem are used in a normal manner with a
well-constructed network, the modem should not be used in situations where failure to transmit or receive
data could result in damage of any kind to the user or any other party, including but not limited to personal
injury, death, or loss of property. Induo accepts no responsibility for damages of any kind resulting from
delays or errors in data transmitted or received using the modem, or for failure of the modem to transmit or
receive such data.
Safety Precautions
General
The modem generates radio frequency (RF) power. When using the modem care must be taken on
safety issues related to RF interference as well as regulations of RF equipment.
Do not use your modem in aircraft, hospitals, petrol stations or in places where using GSM products is
prohibited.
Be sure that the modem will not be interfering with nearby equipment. For example: pacemakers or
medical equipment. The antenna of the modem should be away from computers, office equipment,
home appliance, etc.
An external antenna must be connected to the modem for proper operation. Only uses approved
antenna with the modem. Please contact authorized distributor on finding an approved antenna.
Always keep the antenna with minimum safety distance of 26.6 cm or more from human body. Do not
put the antenna inside metallic box, containers, etc.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Modem may be used at this time.
Using the modem in vehicle
Check for any regulation or law authorizing the use of GSM in vehicle in your country before installing
the modem.
The driver or operator of any vehicle should not operate the modem while in control of a vehicle.
Install the modem by qualified personnel. Consult your vehicle distributor for any possible interference
of electronic parts by the modem.
The modem should be connected to the vehicle’s supply system by using a fuse-protected terminal in
the vehicle’s fuse box.
Be careful when the modem is powered by the vehicle’s main battery. The battery may be drained after
extended period.

Protecting your modem
To ensure error-free usage, please install and operate your modem with care. Do remember the follow:
Do not expose the modem to extreme conditions such as high humidity / rain, high temperatures,
direct sunlight, caustic / harsh chemicals, dust, or water.
Do not try to disassemble or modify the modem. There is no user serviceable part inside and the
warranty would be void.
Do not drop, hit or shake the modem. Do not use the modem under extreme vibrating conditions.
Do not pull the antenna or power supply cable. Attach/detach by holding the connector.
Connect the modem only according to the instruction manual. Failure to do it will void the warranty.
In case of problem, please contact authorized distributor.

Be sure to insert a SIM card before you use the modem.
Note: A SIM card set with PIN code cannot be used normally in the modem. You need to use Modem
Configurator to unlock the PIN code of the SIM card before using it in the modem.
Make sure to disconnect the charger and switch off your modem before inserting or removing your
SIM/USIM card.
Inserting SIM Card
1. Make sure your charger is disconnected.
2. Use a ball pen or paper clip to press the SIM holder eject button. The SIM holder will come out a little.
Then take out the SIM holder.
3. Insert the SIM card, with the metal surface facing downward, make sure it has completely sit on the
tray. Put the tray back into the slot, until you hear “a cracking sound”.
Removing SIM card
1. Make sure your charger is disconnected, and then press and hold down the power key until the
modem is powered off.
2. Press the SIM card until you hear “a cracking sound”, when the SIM card will pop up to be pulled out.
Note:
1.
Don’t pull out the SIM holder without pushing the eject button.
2.
Don’t touch the metal surface of the SIM card in case information in the card is lost or destroyed.
3.
Don’t bend or scratch your SIM card. Keep the card away from electricity and magnetism.
4.
Make sure to disconnect the power source from your modem before inserting and removing your SIM
card.

When DIP switches to Config Mode, user could use follow functions:
1. Configure modem via Modem Configurator;
2. SMS Direct;
3. Auto-reboot;
4. Upgrade firmware.
Serial port default parameters: 115200, 8, None, 1

When DIP switches to Normal Mode, user could use follow functions:
1. Control modem via AT commands;
2. Send/receive SMS via AT commands;
3. CSD communications;
4. GPRS communications;
5. Auto-reboot.
Serial port default parameters: Autobauding
The autobauding mode allows the modem to automatically detect the
transmission speed used by the DTE.
Only the following speeds will be detected: 300, 600, 1200, 2400, 4800,
9600, 14400, 19200, 28800, 38400, 57600, 115200bps. Auto-baud

Indunium-R Modem Configurator is a PC-based configuration software tool for managing and
configuring Induo Indunium 2i modems. With a full graphics mode and Windows-based environment, even
first time users will find it easy to learn how to use this new software tool. Indunium-R Modem
Configurator can be used to configure the general phone settings and modes, but without needing to look
up the appropriate AT commands. Indunium-R Modem Configurator provides a big improvement over the
traditional configuration method that often required frequent checking of a thick AT command reference
manual.
Indunium-R Modem Configurator not only makes configuration easier, but also makes it convenient to carry
out “mass deployment” and “pre-configuration,” but without the need to use AT commands. The most

important benefits of using the “Modem Configurator” utility are:
1. Green software, no need installation;
2. Full graphics mode, easy to learn how to configure the Indunium 2i modems;
3. The configuration profile can be easily stored, and then replicated to other modems;
4. Easy to upgrade modem firmware.
Note: Indunium-R Modem Configurator can be used with Windows 2000/XP/Vista/7 32/64-bit operation
systems.

3. Select the correct serial port that is connected to the modem, then click button.
After that you can see the popup window “Operation Succeed”.
Note: The RS-232 connector uses the standard PINOUT. A direct male DB9 to female DB9 cable can be
used to connect to a PC’s serial port. If you use a USB-to-serial product to configure the modem may
cause unexpected errors when configuring the modem.
