ELECTROMAGNETIC INTERFERENCE AND WARNINGS
3
CAUTION: It is very important that you read this information regarding the possible
effects of Electromagnetic Interference on your power chair.
Powered wheelchairs and motorized scooters may be susceptible to electromagnetic
interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources
such a radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios, and
cellular phones. The interference (from radio wave sources) can cause the motorized
scooter to release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the motorized scooter control system. The intensity of the interfering
EM energy can be measured in volts per meter (V/m). Each motorized scooter can resist
EMI up to a certain intensity. This is called its "immunity level." The higher the immunity
level, the greater the protection will be. At this time, current technology is capable of
achieving at least a 20 V/m immunity level, which would provide useful protection from
the more common sources of radiated EMI. The immunity level of this motorized scooter
model is 20 V/m.
There are a number of sources of relatively intense electromagnetic fields in the everyday
environment. Some of these sources are obvious and easy to avoid. Others are not
apparent and exposure is unavoidable. However, we believe that by following the warnings
listed below, your risk to EMI will be minimized.
Some cellular telephones and similar devices transmit signals while
they are ON, even when not being used.
The sources of radiated EMI can be broadly classified into three types：
1.Hand-held portable transceivers (transmitters-receivers) with the antenna mounted
directly on the transmitting unit. Examples include: citizens band (CB) radios, "walkie
talkie," security, fire, and police transceivers, cellular telephones, and other personal
communication devices.
2.Medium-range mobile transceivers, such as those used in police cars, fire trucks,
ambulances, and taxis. These usually have the antenna mounted on the outside of
the vehicle.
3.Long-range transmitters and transceivers such as commercial broadcast transmitters
(radio and TV broadcast antenna towers) and amateur (HAM) radios.
Because EM energy rapidly becomes more intense as one moves closer to the transmitting
antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of
special concern. It is possible to unintentionally bring high levels of EM energy very close
to the power chair control system while using these devices. This can affect power chair
movement and braking. Therefore, the warnings listed below are recommended to prevent
possible interference with the control system of the power chair.
Other types of hand-held devices, such as cordless phones, laptop computers,
AM/FM radios, TV sets, CD players, and cassette players, and small appliances,
such as electric shavers and hair dryers, so far as we know, are not likely to
cause EMI problems to your motorized scooter.
Power Chair Electromagnetic Interference：
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur
radio (HAM) transmitters, two-way radios, and cellular phones can affect the power chair.
Following the warnings listed below should reduce the chance of unintended brake release
or power chair movement, which could result in serious injury.
Warnings：

1.Do not operate hand-held transceivers (transmitters-receivers), such as citizens band
(CB) radios, or turn ON personal communication devices, such as cellular phones,
while the power chair is turned ON;
2.Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming
close to them;
3.If unintended movement or brake release occurs, turn the power chair OFF as soon
as it is safe;
4.Be aware that adding accessories or components, or modifying the power chair, may
make it more susceptible to EMI; and
5. Report all incidents of unintended movement or brake release to the distributor on the
back cover of this manual. Note whether there is a source of EMI nearby.
Important Information
1.20 volts per meter (V/m) is a generally achievable and useful immunity level against EMI
(as of May 1994). The higher the level, the greater the protection.
2.The immunity level of this product is 20 V/m.

a level surface and clear of any obstacle. Although your power chair is able to climb slopes,
it is safer to practice on a levelled surface.
1.Before operating with your power chair, check the following:
•free-wheeling lever is on D.
•speed dial is at the lowest speed (fully turned counter clockwise).
2.Sit on chair and fasten seat belt.
3.When power is turned on, all battery gauge LED lights should be lit lighting. The self-
diagnostic warning lights should not be blinking.
4.While resting your arm on armrests, joystick should be within reach. By pushing joystick
slightly forward, power chair will move forward slowly, and pushing joystick fully forward,
chair will move at normal speed. And adjusting speed dial will also decrease or increase
speed. Also, with joystick, you are able to turn chair in 360o. When joystick is let go and
back in centre position, chair will stop.
5.Practice driving where there is no obstacle. Start at slowest speed and move forward
and backward; make some turns. As you get more comfortable, you can increase the
speed by turning speed dial knob clockwise.

The joystick controls the direction and speed of the wheelchair.
When the joystick is deflected from the centre position, the wheelchair
will move in the direction of the joystick movement.
The speed of the wheelchair is proportional to the joystick deflection,
so that the further the joystick is moved from the centre position, the
faster the wheelchair will travel.
The joystick can also be used to wake up the system in sleep mode.
Figure 22 Drive inhibit chase
sequence
2.1.2 Emergency stop
If the user needs to stop the wheelchair quickly, the Power button can be pressed to perform
an EMERGENCY STOP. The wheelchair will come to a halt quickly; the rate is set by the
Emergency Deceleration parameter.
2.1.3 Drive inhibit indication
Drive inhibit mode is indicated by the battery gauge with a
right-to-left chase sequence.
The chase sequence starts with the green LED on the right-
hand side, and one-by-one, each LED will switch on and
then off. When the sequence completes at the left-most red
LED, it begins again at the right-hand side.
The chase sequence continues until the error condition has
been cleared.
See also:
If this parameter is set too high, the user can lose balance or fall out of the chair.
2.1.4 OONAPU
figure 23 The joystick
OONAPU ("Out Of Neutral At Power Up") is a safety feature that prevents accidental movement
of the wheelchair, either when powering up, or when the wheelchair comes out of an inhibit
state.
If the LiNX LE System is turned on (or comes out of an inhibit state) while the joystick is not
in the centre position, an OONAPU warning is displayed. During an OONAPU warning, the
battery gauge LEDs will flash continually to alert the user, and the chair will not drive. If the
joystick is returned to the centre position within five seconds, the warning will clear and the
wheelchair will drive normally.
However, if the joystick remains out of neutral for longer than five seconds, an OONAPU error
will occur; the error is displayed by the Status indicator flashing red, and the chair will not
drive. To clear the error, return the joystick to the neutral position and power the unit off and
then on again.

2.1.10 The XLR charger connector
Figure 33 The XLR charger connector
The XLR charger connector, which is located on the right-hand side of the
Remote, is used to connect to either a battery charger or the LiNX Access Key.
The lock function
The lock function is used, primarily, to restrict who can use the system, but also can help prevent
unintentional use of the controls for when the system is not required for any length of time.
When a system is locked (see below), the system is powered down, and the user controls are
not responsive. If the power button is pressed when the system is locked, the locked status is
displayed to the user by the Battery Gauge.
To unlock the system, an unlock sequence must be performed (see below) by the user within
a specific timeframe. If the sequence is not performed correctly, within the timeframe, the system
remains locked.
Warning:
Make sure that the battery charger that is used with the vehicle has a drive inhibit function
that is correctly connected for use with the controller. The maximum voltage on the inhibit
pin must not exceed 3V if a battery voltage is to be detected when the battery charger is
connected. If you are not sure, ask your dealer or vehicle manufacturer.
The XLR charger connector on the Remote is to be used exclusively for the intended purpose.
Warranty will be voided if any unauthorised device is connected to this port.
2.1.11 The LiNX Communications Bus connector
Figure 34 The LiNX
Communications
Bus connector
The LiNX Communications Bus connector can be found on the lower
front of the Remote (see Figure 34 The Remote: user interface and
connectors). The LiNX Communications Bus loom plugs directly into
this socket, providing the Remote with both power and communication
to the power module.
To lock the system, press and hold the Power button for 4
seconds.
When entering the locked state, the battery gauge will indicate
the transition by flashing LEDs 1, 3, and 5 (far left, middle,
and far right) 3 times.
To unlock the system, press the Power button once, and then,
press the Horn button twice - the Horn button must be pressed
twice within 10 seconds of pressing the Power button.
If the user implements the unlock sequence incorrectly, or the Power button
is pressed again before the unlock sequence is complete, the system will
return to the locked state.
During an unlock attempt, the battery gauge will indicate the system is in a
Locked state by flashing LEDs 1, 3, and 5 (far left, middle, and far right) until
either the system is powered off, unlocked, or the Sequence Timeout is reached.

The status indicator
If, when powered up, there is an error with the system, then the status
indicator will flash red. The number of flashes will indicate the type of
error. These are described in the table below.
3 Error indication
Plug the battery charger into the Remote's XLR socket.
The Battery Gauge will indicate the system is being charged
by cycling between a left-to-right chase sequence, and then
displaying the approximate battery charge state at the end of
the chase sequence.
Driving is prevented (inhibited) while the system is being
charged.
The LE system does not have to be powered up when charging
the battery, however, if it is not powered up, then the battery
gauge will not display the charging state/ chase sequence.
Warning:
The maximum charging current for the LiNX LE System is 6A.
The wheelchair manufacturer must specify an appropriate battery charger for the batteries
used in the wheelchair.
The wheelchair manufacturer must also specify the maximum current of any battery
chargers to be used with the controller and warn against using battery chargers of higher
current ratings.
The battery charger must have over-current protection in the form of a non-resettable fuse.
It is the responsibility of the wheelchair manufacturer to manage the risks of battery
over-charging and any related gas emissions.
To protect the wheelchair wiring from over currents while charging the batteries, chargers
must have the ability to reduce their current output when electrically shorted.
