line, perpendicularly to the slope.
•Do not go down in a slope in reverse.
•Always actuate the lever gently when you start moving in a slope in order to avoid tipping the
wheelchair.
•Do not make a half-turn in a slope.
•Reduce your speed in restricted or encumbered areas.
•Reduce your speed in a crowd and use your horn to announce your presence.
•In front of an obstacle you must stop and cross it perpendicularly and gradually.
•Avoid thresholds of more than 1 ½ in (38 mm), they can endanger your stability.
•Use the elevators to move you from one level to another.
•Do not approach a slope surface exceeding 10° (17% slope).
•Always fasten your seat belt.
•Keep legs on the legrest while driving.
1.1.3 TO CARRY OUT TRANSFERT
•Always put the on/off switch of the joystick box on the OFF position before carrying out a
transfer.
•Never lean forward or backward to reach an object.
•Always place yourself sideway and the nearest you can to the object to reach.
•Use the transfer supports on the armrests to raise yourself, after you made sure that they
are correctly in position.
•If your backrest is inclined, do not sit down on the backrest, you could damage the backrest
and tip the wheelchair.
•Do not raise yourself upright on the footplates, you could damage and/or tip the wheelchair.

requirements, rules, laws, protocols, directives, norms, standards, instructions and
recommendations pertaining to such use by competent authorities.
•Do not travel on tilted surfaces when the wheelchair is in free wheel. If you have to do it,
the caregiver must always be oriented in the direction of the bottom of the slope.

1.2 WHAT ABOUT THE ELECTROMAGNETIC ENERGY
All electronic instruments which transmit remote informations are generally apparatus
which emit in the environment some radio waves. These radio waves are called "
electromagnetic energy ".
The functionality of an electronic instrument can be deteriorated by this electromagnetic
energy field. It is what we call "an electromagnetic interference". Stronger the intensity
of energy is, greater the risk of bad functional problem of the apparatus increase. This
energy is measured in volt per meter (V/m).
All motorized wheelchair are suitable to be affected by these interferences. However,
current technology makes it possible to immunize them against these risks. It is what is
called their electromagnetic level of immunity to the interference, measured also in volt
per meter (V/m).
20 V/m is a level of immunity which offer a good protection against the electromagnetic
interferences. The electronic parts of the R-NET electronic from do meet
standard directive IEC 1000-4-3.
To avoid electromagnetic interferences, it is important to read
and respect the following warning section, before to use your
wheelchair for the first time.

1.2.1 CAUTION
Waves emitted by :
•Radio and television stations;
•Amateur radio;
•Radio transmitters and receivers;
•Cellular phones;
•Computers laptop.
CAN AFFECT THE CORRECT FUNCTIONALITY OF MOTORIZED WHEELCHAIR.
1.2.2 USING TRANSMITTERS AND RECEIVERS
•Avoid proximity of these sources of electromagnetic emissions.
•Always put the joystick box in the OFF POSITION before using a cellular phone or a CB
apparatus.
•The addition of electric accessories and/or electric modifications made to the wheelchair
will modify its level of immunity to the electromagnetic emissions.
•Always put the key in the OFF POSITION as soon as it safe to do it and that appears an
erratic operation with the wheelchair.
•Please forward any incident of this kind to .
