consumers/end users. The installation implementing or setting into operation
of the product can only be performed by this qualified personnel.
1.1 General
This description is focused on the GSM/GPRS and GPS terminal STEPPIII from
FALCOM GmbH. It contains information about purpose and use of the
STEPPIII concept.
In order quickly to start and immediately and comprehensive to use all
functions and to avoid any mistakes of STEPPIII terminal on your utilization, we
recommend to read the following references and suggestions for using your
new STEPPIII terminal.
The STEPPIII concept represents further development of the
ALCOM STEPP and STEPP II concept. The new device can be easily
integrated into existing STEPPII designs or into a variety of new applications. It
is functional, mechanical and software compatible to the popular
STEPPII-55/56-GPRS device family.
Compared to previous STEPP and STEPP II terminals the new STEPPIII concept
embeds Quad Band GSM/GPRS core high-sensitivity 20-channel GPS core
3D-motion sensor 1100 mA/h Li-Polymer battery.
The STEPPIII terminal is a Plug & Play GSM/GPRS/GPS terminal with an
embedded configurable software that provides even greater performance
and flexibility for its users and system integrators to develop high-
performance applications. STEPPIII is a completely self-contained and
battery-powered system with a stand-alone software that provides location-
based applications. It is designed for indoor fixed mounting. The device
concept is targeting for direct implementation as a mobile client in a wide
range of high volume, low-cost, flexible system solutions li e AVL, fleet
management, vehicle security and recovery and other related area. The
trac ing functionality of the embedded mobile client application is
combined with variety of alert messaging capabilities. The configurable alert
messages contain current position and status report and use 2 digital inputs,
4 analog or digital inputs and 4 digital outputs as hardware bac -bone.
Depending on how the system is set up, 4 digital outputs allow remote
control of external actuators. In addition to that two predefined digital inputs
are detecting ignition line and main power (car battery) failure, and so you
may handle these events and use as notification. Nevertheless, if the external
power source fails, the internal rechargeable 1100 mA Li-Polymer battery
provides continuous operation for about 10-12 hour after full charged
(configuration dependent).
The embedded software comprises a set of word-like commands termed
“PFAL” needed for executing particular actions reading or setting particular
configurations. These commands are valid for all inds of operations
including SMS, CSD, TCP and SMTP.

2 SECURITY
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM-MODEM
READ THIS INFORMATION BEFORE USE!
Your cellular engine STEPPIII is one of the most exciting and innovative
electronic products ever developed. With it you can stay in contact with
your office your home emergency services and others wherever service is
provided.
This chapter contains important information for the safe and reliable use of
the STEPPIII. Please read this chapter carefully before starting to use the
cellular engine STEPPIII.
2.1 General information
Your STEPPIII device utilizes the GSM/GPRS/GPS standard for cellular
technology. GSM/GPRS is a newer radio frequency („RF“) technology than
the current FM technology that has been used for radio communications for
decades. The GSM standard has been established for use in the European
community and elsewhere. Your modem is actually a low power radio
transmitter and receiver. It sends out and receives radio frequency energy.
When you use your modem the cellular system handling your calls controls
both the radio frequency and the power level of your cellular modem.
For the use of the acquired devices SIM cards are needed which are not
included in the scope of delivery of the device. The SIM cards can be
acquired e.g. by specific providers. From the use of the SIM cards can result
additional costs which are to be borne by the purchaser (client) of the
devices. The seller does not cover the extra costs for the use of the devices.
The seller gives no recommendation for the use of specific SIM cards and
does not liable also for the fact that the devices are usable with all available
SIM cards. The seller also covers no other costs that are needed for the
application of the customer in connection with this device.
2.2 Exposure to RF energy
There has been some public concern about possible health effects of using a
GSM modem. Although research on health effects from RF energy has
focused for many years on the current RF technology scientists have begun
research regarding newer radio technologies such as GSM. After existing
research had been reviewed and after compliance to all applicable safety
standards had been tested it has been concluded that the product is fit for
use.
If you are concerned about exposure to RF energy there are things you can
do to minimize exposure. Obviously limiting the duration of your calls will
reduce your exposure to RF energy. In addition you can reduce RF exposure
by operating your cellular modem efficiently by following the guidelines
below.

Page 10

STEPPIII Ha dwa e desc iption Ve sion 1.0.0
2.3 Efficient modem operation
In order to operate your modem at the lowest power level consistent with
satisfactory call quality please take note of the following hints.
If your modem has an extendible antenna extend it fully. Some models allow
you to place a call with the antenna retracted. However your modem
operates more efficiently with the antenna fully extended.
Do not hold the antenna when the modem is „IN USE“. Holding the antenna
affects call quality and may cause the modem to operate at a higher power
level than needed.
2.4 Antenna care and replacement
Do not use the modem with a damaged antenna. If a damaged antenna
comes into contact with the skin a minor burn may result. Replace a
damaged antenna immediately. Consult your manual to see if you may
change the antenna yourself. If so use only a manufacturer-approved
antenna. Otherwise have your antenna repaired by a qualified technician.
Use only the supplied or approved antenna. Unauthorized antennas
modifications or attachments could damage the modem and may
contravene local RF emission regulations or invalidate type approval.
2.5 Dri ing
Check the laws and regulations on the use of cellular devices in the area
where you drive. Always obey them. Also when using your modem while
driving please pay full attention to driving pull off the road and park before
making or answering a call if driving conditions so require. When applications
are prepared for mobile use they should fulfill road-safety instructions of the
current law!
2.6 Electronic de ices
Most electronic equipment for example in hospitals and motor vehicles is
shielded from RF energy. However RF energy may affect some
malfunctioning or improperly shielded electronic equipment.
2.7 Vehicle electronic equipment
Check your vehicle manufacturer’s representative to determine if any on
board electronic equipment is adequately shielded from RF energy.
2.8 Medical electronic equipment
Consult the manufacturer of any personal medical devices (such as
pacemakers hearing aids etc.) to determine if they are adequately
shielded from external RF energy.
Turn your STEPPIII device OFF in health care facilities when any regulations
posted in the area instruct you to do so. Hospitals or health care facilities
may be using RF monitoring equipment.

Page 11

STEPPIII Ha dwa e desc iption Ve sion 1.0.0
2.9 Aircraft
Turn your STEPPIII OFF before boarding any aircraft.
Use it on the ground only with crew permission.
Do not use it in the air.
To prevent possible interference with aircraft systems Federal Aviation
Administration (FAA) regulations require you to have permission from a crew
member to use your modem while the plane is on the ground. To prevent
interference with cellular systems local RF regulations prohibit using your
modem whilst airborne.
2.10 Children
Do not allow children to play with your STEPPIII device. It is not a toy. Children
could hurt themselves or others (by poking themselves or others in the eye
with the antenna for example). Children could damage the modem or
make calls that increase your modem bills.
2.11 Blasting areas
To avoid interfering with blasting operations turn your unit OFF when in a
“blasting area” or in areas posted: „turn off two-way radio“. Construction
crew often use remote control RF devices to set off explosives.
2.12 Potentially explosi e atmospheres
Turn your STEPPIII device OFF when in any area with a potentially explosive
atmosphere. It is rare but your modem or its accessories could generate
sparks. Sparks in such areas could cause an explosion or fire resulting in
bodily injury or even death.
Areas with a potentially explosive atmosphere are often but not always
clearly marked. They include fuelling areas such as petrol stations; below
decks on boats; fuel or chemical transfer or storage facilities; and areas
where the air contains chemicals or particles such as grain dust or metal
powders.
Do not transport or store flammable gas liquid or explosives in the
compartment of your vehicle which contains your modem or accessories.
Before using your modem in a vehicle powered by liquefied petroleum gas
(such as propane or butane) ensure that the vehicle complies with the
relevant fire and safety regulations of the country in which the vehicle is to
be used.
2.13 Non-ionizing radiation
As with other mobile radio transmitting equipment users are advised that for
satisfactory operation and for the safety of personnel it is recommended
that no part of the human body is allowed to come too close to the antenna
during operation of the equipment.
