• REAL 6100 PLUS is classified as class A and is intended for indoor use only.
• Max user weight: 135 kg. Please contact Mercado Medic AB in connection with adjustment for heavier users.
• The driving programs must be adapted for the user to ensure that the wheelchair can be safely operated with respect to the
user and his/her surroundings. Driving programs may only be adapted by qualified coordinators and technicians.
Programming is done using the appropriate software, see section “Programming the controller” on p. 22.
• REAL 6100 PLUS is tested and approved according to the EMC-directive. However, the wheelchair can affect and be
affected by equipment in its immediate vicinity which generates electromagnetic fields, such as alarm systems, electric
generators and mobile phones.
•
REAL 6100 PLUS may not be equipped with accessories or components other than the ones authorised by Mercado Medic AB.
• Warranty period: two (2) years unless otherwise agreed. For warranty-related matters, please contact Mercado Medic AB.
• Max. service life: ten (10) years.
• Repairs or other engineering work may only be performed by personnel authorised by Mercado Medic AB.
• Wheelchair with adjustable seat angle must be in fixed position when the user is sitting in or rising up from the chair.
• REAL 6100 PLUS must not be operated when the seat height is in raised position. If the seat is raised, its obstacle climbing
ability might deteriorate because the wheelchair moves more slowly and less power comes to the drive wheels. To safely
overcome obstacles, the wheelchair runs with the lowest possible seat height.
• REAL 6100 PLUS comes with back, seat and leg support.
• The wheelchair is approved for all types of transport. Nonetheless, the automatic fuse, see Section 11 on the next page,
must be switched off during transport.
• This symbol warns against the risk of crushing and about positions/situations where we point to risks:
•
If REAL 6100 PLUS is equipped with leg rests, the user's feet must be held on the foot plate when using the electric functions.
• Be careful when lifting the battery pack as it is heavy and might cause crushing if dropped.
• In connection with service, always re-install the protective cover of the battery terminal. Failure to do so might result in
personal injury in the event of later service.
• Do not leave small children without supervision in the vicinity of the product. The cover plug on the front cover poses a
choking hazard for small children. See Your REAL 6100 PLUS for reference.

GETTING IN AND OUT OF THE WHEELCHAIR
GETTING IN AND OUT OF THE WHEELCHAIR
Things to consider: Always consult your coordinator about the most suitable technique for getting to and out of
the wheelchair, from the front or from the side. Consider what best suits you and your needs and thus poses the
least risk of injury.
WARNING: Getting in and out of the chair must only be done on a flat surface. Position the chair correctly and
adjust the seat height to the right position.
WARNING: Make sure that the controller is switched off and that the brake is not disengaged at the moment of
getting in or out of the wheelchair in order to prevent the it from moving unexpectedly.
90°
GETTING IN OR OUT OF THE WHEELCHAIR
FROM THE SIDE
When getting in or out of the wheelchair from the side
of the chair, the wheelchair seat must be slightly lower
than the user’s position. When getting out of the wheel-
chair, it is possible to raise the chair so that the user
would sit slightly higher than his/her position when
moving. Keep in mind that you only have to drop or
lower the wheelchair armrest on the side to which you
are moving.
GETTING IN OR OUT OF THE WHEELCHAIR
FROM THE FRONT
When getting in or out of the wheelchair from the front,
strive to ensure that the front edge of the seat is not
higher than the user's knee joint. This is done in order to
get far into the seat without adjusting it. Remember to
drop or alternatively lower the foot plate to get close to
the seat. When using a lifting device to get in or out of
the chair, consider the possible crushing risks. Make sure
your hands, feet and any clothing cannot get in the way,
thereby posing a risk of injury.
RAMPS
WARNING: Before driving on a ramp you must verify that
it can handle the total weight of you and your electric
wheelchair. Lower the seat lift and straighten the seat tilt
when driving on a ramp to increase the stability of the
wheelchair. When driving on a ramp, we recommend
to always reverse the chair. If the downhill slope is more
than 3 degrees, the chair must be reversed.
Always drive straight ahead from the ramp, not obliquely.

2. Connect the charging socket (1) to the charging
jack (2) (labelled battery symbol). The power cord
and charging socket can be connected in any order.
3. Green LED (4) flashes during charging. The
charger gets warm during charging. That is
absolutely normal. There is overheating protection.
4. Green LED (4) lights up when the battery is ready
for use which takes at least six hours, regardless of
the initial battery level. Since the charger draws
some power and does not overcharge the battery,
it can be left connected until the vehicle is put
into use.
5. Disconnect the charging socket from the charging
jack (2) when the vehicle is to be used.
6. Disconnect the power cord (3), if desired.
WARNING
• Batteries emit explosive gases during charging. Avoid
flames and sparks.
• The charger is designed only for lead batteries with
12 cells (24V).
• The charger is equipped with overheating protection
• but gets warm during charging.
• Charging must take place in a well-ventilated area.
• Medical electric equipment requires special
precautions and must meet the requirements of ISO
7176-21, where charger and wheelchair are tested
together according to EMC. The tests pursuant to this
standard check that our product, wheelchair including
charger, cannot disrupt or be affected by portable or
mobile RF communication equipment.
• Cables and sockets may only be replaced by the
manufacturer or an authorised workshop.
• High heat in a socket indicates that it is worn out or
damaged. In that case, both male and female sockets
must be replaced.
MAINTENANCE AND SUPERVISION
• Before each charging, inspect the cables and sockets
to ensure that they are not damaged or worn out. If
they are, the charger must be replaced immediately.
• For best performance, economy and charger service
life, battery and travelled distance per charge, the
following advice should be followed:
• Charger, sockets and batteries must be kept clean
from dirt, dust and oxide.
• Turn off the vehicle when it is not in use.
•
Charge the battery every day or as soon as it is depleted.
• Maintenance charge the battery when the vehicle is not
used for a long time*.
• If necessary, clean the charger with a slightly damp cloth.
* Since the charger draws some power and does not
overcharge the battery, it can be left connected until
the vehicle is put into use.

CHARGING/DISCHARGING
• Charge for 12 hours before the first use.
• After that, charge after each discharge, even if the battery
is not completely depleted.
• Never store a fully discharged battery.
• A fully discharged battery must be charged for at least
16 hours.
• If the charging time is less than 16 hour more than 3
times, the battery must be charged for 24 hours once
to make up for the poor charging.
• The ambient temperature during charging must be
between 10°C and 30°C.
HIGH AMBIENT TEMPERATURE
The battery should not be charged if the ambient
temperature exceeds 30°C. The charger is set to
charging voltage valid at 20°C.
LOW AMBIENT TEMPERATURE
Charging at temperatures below 10°C is not
recommended. The available capacity decreases at low
temperatures.
DEEP DISCHARGE
Try to avoid deep discharges. If the battery has been
fully discharged, it has to be charged as soon as
possible for at least 24 hours.
LONG-TERM STORAGE
Disconnect the batteries if the wheelchair is not be
used for a long period of time. This is done with the
help of the automatic fuse (see section 11 on page 3).
Press Off to disconnect the batteries. If the wheelchair
is to remain in storage for more than 4 months, it
requires maintenance charging to uphold the battery
capacity (see chapter “Charging”). Turn on the
automatic fuse before charging.
When the wheelchair is put into use again, turn on
the automatic fuse and press On. Also make sure to
charge the wheelchair before use.
CONSIDER THE FOLLOWING WHEN
DEALING WITH BATTERIES:
• Do not ever short-circuit the battery.
• Do not subject the battery to strong impacts.
• The battery should be replaced after three (3) years to
reduce the risk of leakage.
• In case of contact with battery acid, rinse off with water
for about 15 minutes, consult a doctor.
• Used batteries must always be discarded at a recycling
station.

ERROR MESSAGE IN THE EVENT
OF MALFUNCTION
Each DX error will be indicated by flashing of the
controller LED near the on/off power switch The
flashes come in groups and range from 1 to 11 at a
2-second interval. The number (1-11) of flashes shows
which error has occurred.
ABOUT THE TABLE
In case of serous faults that affect the driving safety,
the electric wheelchair will automatically stop. Less
serious errors will only be indicated on the control
LED, and the electric wheelchair can continue its
operation.
When some errors occur, the electronics is reset once
the error has been rectified, and the control LED is
once again steady. Other errors can be connected,
meaning that the electric wheelchair must be switched
off for at least 2 seconds and then turned on again in
order to reset the system.
In case of minor errors, the electronics can switch to
backup driving mode. This means that the electrical
wheelchair can still operate, but all speed variables will
be reduced.

1 FLASH – USER ERROR
Time-out, motor stop or user error. Release the
joystick so that it is in neutral position and try to
drive again.
2 FLASHES – BATTERY ERROR
is means that the battery voltage is too low to
be able to drive the electric wheelchair. Charge the
batteries and check whether the control LED of the
charger indicates that the wheelchair is charging. If
the error persists, measure the battery voltage both
with and without connected charger. If there is a
considerable dierence in the voltage, the batteries
are probably not working properly and need to be
replaced. Also inspect the battery connections and
cables.
3 FLASHES – RIGHT (M1) MOTOR
is means breakage or short-circuiting of
the cable from the M1 socket of the electronics
module to the motor, or motor failure. Check by
pulling out the M1 connector and measuring the
resistance between the outermost pins (1 and 4), in
order to detect breakage or short-circuiting.
4 FLASHES – LEFT (M2) MOTOR

5 FLASHES – RIGHT (M1) PARKING BRAKE
is means breakage or short-circuiting of the M1
socket of the electronics module for the parking brake,
or alternatively, parking brake fault. Check by pulling
out the M1 connector and measuring the resistance
between the inner pins (2 and 3), to detect breakage
or short-circuiting.
Check also whether the release control of the parking
brake actually resets the brakes when the lever is
moved to driving position.
6 FLASHES – LEFT (M2) PARKING BRAKE
See above but for the M2 socket.
7 FLASHES – SHARK CONTROLLER ERROR
Inspect cords and connections to the SHARK
controller's communication bus. If the error persists
replace the controller.
8 FLASHES – SHARK POWER MODULE
ERROR
Inspect cords and connections on the SHARK
controller. If the error persists replace the controller.
9 FLASHES – SHARK COMMUNICATION
ERROR
Make sure the battery voltage is more than 17 V.
Make sure that the bus cables are properly connected
to SHARK. Try replacing the SHARK power module.
If this does not work, replace the SHARK controller.
10 FLASHES – UNKNOWN ERROR
Check all cables and connections. If no error is found,
contact Mercado Medics Service.
11 FLASHES – INCOMPATIBLE CONTROLLER
e controller is not compatible with the power
module. Make sure the SHARK version is used for
both controller and power module.
SHARK SYSTEM SERVICE
All cables and connectors must be inspected
regularly for damage and oxidation. Loose, oxidised
connectors or damaged cables must be replaced. All
components in the SHARK system must be kept
clean from dust, dirt and liquids. Clean with a cloth
moistened with hot water or alcohol. Do not use
solvents. Only use agents approved by Mercado Medic
AB. Normally, there are no parts in the system that
