2Safety precautions
IMPORTANTIMPORTANT
FOR THE EFFICIENT AND SAFE OPERATION OFFOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM INTEGRATEDYOUR GSM INTEGRATED MODEMMODEM
READ THIS INFORMATION BEFORE USEREAD THIS INFORMATION BEFORE USE
2.1 RF safety
2.1.1 General
Your WMOi3 integrated modem is based on the GSM standard for cellular
technology. The GSM standard is spread all over the world. It covers Europe, Asia
and some parts of America and Africa. This is the most used telecommunication
standard.
Your modem is actually a low power radio transmitter and receiver. It sends out
and receives radio frequency energy. When you use your WMOi3 integrated
modem, the cellular system which handles your calls controls both the radio
frequency and the power level of your cellular modem.
2.1.2 Exposure to RF energy
There has been some public concern about possible health effects of using GSM
modems. Although research on health effects from RF energy has focused on the
current RF technology for many years, 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 was fitted 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 below guidelines.
2.1.3 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.

être communiqué ou divulgué à des tiers sans son autorisation préalable.
2.1.4 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. Unauthorized antennas, modifications
or attachments could damage the modem and may contravene local RF emission
regulations or invalidate type approval.

2.2 General safety
2.2.1 Driving
Check the laws and the regulations regarding the use of cellular devices in the area
where you have to drive as you always have to comply with them. 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
require.
2.2.2 Electronic devices
Most electronic equipment, for example in hospitals and motor vehicles is shielded
from RF energy. However RF energy may affect some improperly shielded
electronic equipment.
2.2.3 Vehicle electronic equipment
Check your vehicle manufacturer representative to determine if any on-board
electronic equipment is adequately shielded from RF energy.
2.2.4 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.
2.2.5 Aircraft
Turn your modem 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 aircraft is on the ground. To prevent
interference with cellular systems, local RF regulations prohibit using your
modem while airborne.
2.2.6 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.

2.2.7 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.
2.2.8 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 injuries or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly
marked. They include fueling 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.
2.3 Safety standards
THIS WMOi3 INTEGRATED MODEM COMPLIES WITH ALL APPLICABLE RF
SAFETY STANDARDS.
This cellular modem meets the standards and recommendations for the
protection of public exposure to RF electromagnetic energy established by
governmental bodies and other qualified organizations, such as the following :
