IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM MODEM READ THIS INFORMATION BEFORE USE !
Your GSM modem 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.
GENERAL
Your modem utilises the GSM 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.
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 below guidelines.

Security User Manual
Page 12 Version 1.00 TWIST GSM-Modem
EFFICIENT MODEM OPERATION
For your modem to operate at the lowest power level, consistent with
satisfactory call quality:
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.
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.
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: give full attention to driving, pull off the
road and park before making or answering a call if driving conditions so
allow. When applications are prepared for mobile use they should fulfil
road-safety instructions of the current law!
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.

User Manual Security
TWIST GSM-Modem Version 1.00 Page 13
VEHICLE ELECTRONIC EQUIPMENT
Check your vehicle manufacturer’s representative to determine if any
on board electronic equipment is adequately shielded from RF energy.
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 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.
AIRCRAFT
Turn your modem OFF before boarding any aircraft.
Use it on the ground only with crew permission.
Do not use 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.
CHILDREN
Do not allow children to play with your 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.

Security User Manual
Page 14 Version 1.00 TWIST GSM-Modem
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.
POTENTIALLY EXPLOSIVE ATMOSPHERES
Turn your modem 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 and damages to property.
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.
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 Ωcoaxial 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.
