INTRODUCTION
The Enigma powerchair has been designed for a single occupant user mass of up
to 135Kg. The design of the powerchair assumes that the user has limited mobility
but has the physical, visual and cognitive ability to operate the powerchair safely.
The powerchair is suitable for everyday indoor and outdoor use. It is suitable for
use on outdoor pavements, patios, paths, gravel and similar environments. It is not
suitable for fields, ditches or similar. If the powerchair is used in heavy rain or in
the wet for prolonged periods, the user and powerchair should be protected with a
rain cape.
All Enigma powerchairs are manufactured to the highest standards and are CE
compliant. Medicare Technology is an ISO 9001 and ISO 13485 accredited
medical device manufacturer.
The Enigma powerchair is a robust and visually appealing product whilst being a
cost-effective solution to mobility problems. The attributes of this powerchair are
its versatility and comfort. Using tried and tested industry electronics gives a
highly reliable product.
It is essential that you read this manual before using your Enigma powerchair. If
you have any questions about the manual or the powerchair in general, please
contact the outlet where you purchased the powerchair.

PERSONAL SAFETY
GENERAL OPERATING SAFETY PROCEDURES
Make sure that the powerchair is switched off before mounting or
dismounting from the chair.
For your health and comfort, make sure that you adopt a comfortable
posture and that you can operate the controller unit with ease.
Make sure you are visible when using the chair at night or in poorly lit
conditions.
Be careful when driving your powerchair as evening falls. It has not been
designed for use at night or for use in severe weather conditions such as
rain, snow, etc).
Ensure that all modifications made to the powerchair are approved by
Medicare Technology. Unauthorised modifications may reduce the
performance of the powerchair, invalidate warranty, or result in injury or
damage.
There is a risk of trapping with power chairs. Ensure all clothing is kept
away from moving parts (e.g. wheels and motors)
Drive on the pavement and pedestrian areas only. The powerchair can be
used to cross the road on a single carriageway where there is no pavement.
Do not take the powerchair on escalators
Do not use a mobile phone or other wireless communication devices whilst
driving as they could interfere with the powerchair controls. Always switch
off the powerchair before using a mobile phone.
EMERGENCY BRAKING
To apply emergency braking whilst using the power chair release the grip
on the control joystick.
You can also apply emergency braking by turning off the powerchair.
However, this is an abrupt braking method and should only be used as a last
resort.
There is a brake at each side of the wheel. These brakes should only be used
when the powerchair is stationary and when in freewheel mode.

PERSONAL SAFETY (CONTINUED)
TURNING AND USING ON A GRADIENT GUIDELINES
Avoid sharp turns at high speed as this could result in the powerchair
tipping over. This is especially relevant when turning on a gradient.
The powerchair has been designed for use on gradients up to 1 in 6 (10%).
However, other factors such as the surface of the gradient or the attributes of
the user can vary this figure. If you are in any doubt about going up or down
a gradient please find an alternative route.
Please slow down when driving on gradients.
EMERGENCY FREEWHEEL
Warning: The powerchair has a freewheel option device fitted on the top of
each motor. Always re-engage the emergency freewheel device after use.
Failure to do so may result in injury.
OBSTACLES AND KERBS
Be careful when driving to avoid obstacles which could come in to contact
with the powerchair, in particular the front castors. If you cannot avoid an
obstacle, then negotiate it slowly with care.
Repeated heavy impacts could reduce the performance of the powerchair
and may result in damage or injury.
If you have a kerb climber installed, please refer to the separate kerb
climber section before using.
ELECTROMAGNETIC INTERFERENCE (EMI) FROM RADIO WAVES
1. Powered wheelchairs 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 mobile phones. The interference (from
radio wave sources) can cause the powered wheelchair to release its
brakes, move by itself, or move in an unintended direction. It can also
permanently damage the powered wheelchair’s control system.
Enigma Energi Owners Handbook Page 5 of 24 Part Code: Z20949 (Rev G)
PERSONAL SAFETY (CONTINUED)
The intensity of the interfering EM energy can be measured in volts per metre
(V/m). Each powered wheelchair can resist EMI up to a certain intensity. This is
called its “immunity level”. The higher the immunity level, the greater the
protection. 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. This powered wheelchair model as shipped,
with no further modification, has an immunity level of 20 V/m without any
accessories.
There are a number of sources of relatively intensive 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.
The source of radiated EMI can be broadly classified into three types:
1. Hand-held portable transceivers (transmitter-receivers with the antenna
mounted directly on the transmitting unit). Examples include citizens
band (CB) radios, walkie talkies, security, fire and police transceivers,
mobile phones and other personal communication devices.
2. Medium range mobile transceivers, such as those used in police cars, fire
engines, 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 control system of the powerchair while
using these devices. This can affect powered wheelchair movement and braking.
Therefore, the warnings listed overleaf are recommended to prevent possible
interference with the control system of the powered wheelchair. Following the
warnings listed below should reduce the chance of unintended brake release or
movement as a result of EMI:
Enigma Energi Owners Handbook Page 6 of 24 Part Code: Z20949 (Rev G)
PERSONAL SAFETY (CONTINUED)
1. Do not operate hand-held transceivers-receivers, such as citizens band
(CB) radios, or turn ON personal communication devices, such as mobile
phones, while the Powerchair 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 Powerchair OFF
as soon as it is safe to do so.
4. Be aware that adding accessories or components, or modifying the
Powerchair, may make it more susceptible to EMI (there is no easy way to
evaluate their effect on the overall immunity of the Powerchair).
5. Report all incidents of unintended movement or brake release to the
Powerchair manufacturer and note whether there is an EMI source nearby

Joystick
1. Joystick. The primary function of the joystick is to control the
speed and direction of the wheelchair. The further you push the
joystick from the center position the faster the wheelchair will
move. When you release the joystick the brakes are automatically
applied.
2. On / Off button. The on/off button applies power to the control
system electronics, which in turn supply power to the wheelchair’s
motors. Do not use the on/off button to stop the wheelchair unless
there is an emergency. (If you do, you may shorten the life of the
wheelchair drive components). The battery gauge shows you that
the wheelchair is switched on. It also indicates the operating status
of the wheelchair.
3. Increase Speed / Profile. Press this button to increase the
maximum speed of the wheelchair.
4. Decrease Speed / Profile. Press this button to decrease the
maximum speed of the wheelchair.
Enigma Energi Owners Handbook Page 9 of 24 Part Code: Z20949 (Rev G)
5. Speed / Profile Indicator. This shows the maximum speed of the
wheelchair. The more LEDs are lit, the faster the maximum speed.
The wheelchair can be configured to use drive profiles. However,
this is not included by default. For more information about drive
profiles, contact your dealer. If the speed indicator ripples, this
means the wheelchair is locked. By default the locking function is
disabled.
To unlock / lock the wheelchair:
Switch the wheelchair on
Hold down the on/off button for 1 second (lock only)
Deflect the joystick forwards until the control system bleeps
Deflect the joystick backwards until the control system bleeps
Release the joystick. There will be a long bleep and the
wheelchair will be unlocked / locked.
6. Horn. Press this button to sound the horn. The horn will stop when
you release the button.
7. Battery Gauge. This shows the battery power level of the
wheelchair.
The more LEDs that are lit, the more power is left in the battery.
The LEDs will be lit constantly when the wheelchair is operating
normally.
If the LEDs on the battery gauge are stepping up (i.e. the number
of LEDs lit quickly increases then resets to 1), the battery charger
is connected and the wheelchair drive inhibited.
If the battery gauge is flashing slowly then the wheelchair is
operating normally, but the batteries need recharging as soon as
possible.
If the battery gauge LEDs are flashing rapidly this indicates a fault
with the wheelchair. If you have a problem with your wheelchair
consult the table overleaf. If the problem persists after you have
followed the advice overleaf then restarted the wheelchair, contact
Enigma Energi Owners Handbook Page 10 of 24 Part Code: Z20949 (Rev G)
your dealer.
