1 Security
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM-MODEM, READ THIS INFORMATION BEFORE USE!
Your cellular engine FALCOM C2D-SI 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 FALCOM C2D-SI. Please read this chapter carefully before starting to
use the cellular engine FALCOM C2D-SI.
1.1 General information
Your FALCOM C2D-SI modem utilises the GSM/GPRS standard for
cellular technology. GSM 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.
1.2 Exposure to RF energy
There has been some public concern about possible health effects of using
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 minimise 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.
1.3 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.

FALCOM C2D-SI VERSION 1.07
1.4 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. Unauthorised antennas,
modifications or attachments could damage the modem and may contravene
local RF emission regulations or invalidate type approval.
1.5 Driving
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 fulfil road-safety
instructions of the current law!
1.6 Electronic devices
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.
1.7 Vehicle electronic equipment
Check your vehicle manufacturer’s representative to determine if any on
board electronic equipment is adequately shielded from RF energy.
1.8 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 FALCOM C2D-SI modem 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.
1.9 Aircraft
Turn your FALCOM C2D-SI 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.

1.10 Children
Do not allow children to play with your FALCOM C2D-SI modem. 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.
1.11 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.
1.12 Potentially explosive atmospheres
Turn your modem FALCOM C2D-SI 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.
1.13 Non-ionising 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 be allowed to come too close to the antenna
during operation of the equipment.
The radio equipment shall be connected to the antenna via a non-radiating
50 Ohm coaxial cable.
The antenna shall be mounted in such a position that no part of the human
body will normally rest close to any part of the antenna. It is also
recommended to use the equipment not close to medical devices as for
example hearing aids and pacemakers.

2 Safety standards
This GSM modem complies with all applicable RF safety standards.
The embedded GMS modem meets the safety standards for RF receivers
and the standards and recommendations for the protection of public
exposure to RF electromagnetic energy established by government bodies
and professional organizations, such as directives of the European
Community, Directorate General V in matters of radio frequency
electromagnetic energy.
