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 as radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios,
and cellular phones. The interference (from radio wave sources) can cause the power
chair to release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the power chair control system. The intensity of the interfering
EM energy can be measured in volts per meter (V/m). Each power chair 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 product 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.
Electromagnetic Interference and Warnings :
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 power chair.
Power Chair Electromagnetic Interference :
2-5 ELECTROMAGNETIC INTERFERENCE AND WARNINGS
•Be mindful of road conditions and pass through obstacles slowly.
•Even though your power chair has been rated with maximum climbable, we suggest
not driving through an obstacle.

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.
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;
5.Report incidents of driving or brake malfunctions to the distributor listed on the first page
of this manual and take note of any source of EMI.

OONAPU 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.
Cut-off voltage
When the battery voltage decreases below the battery cut-off voltage:
•the first (red) LED will flash on the battery gauge
•the horn will sound once every 10 seconds
•Charge the battery immediately to avoid damaging the battery.
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 section 6-1 for error indication)
Battery charging
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.
