GLOSSARY
The term Joystick, when used in this docu-
ment, is a synonym for any type of steering
devices on your wheelchair, such as e.g.:
– Chin steering
– Mini-joystick
– Contact steering,
etc.
INTRODUCTION
Read this manual before you use the
wheelchair for the first time and follow
the instructions carefully. If children or
teenagers will be using the wheelchair,
they should first read this manual along
with their parents or guardians before us-
ing the chair.
You can control your electric wheelchair via
the control module and an optional con-
nected joystick.
☞Accessories and extra features such as
e.g. external button controllers are not
part of the standard delivery.
If you use the control module or the control
module accessories inappropriately, you
may put yourself or others at risk, therefore,
it is important to learn to use the equip-
ment properly.
This operating manual will help you get
comfortable using the control module so
that you can avoid accidents.
For visually impaired users, PDF files with
additional information about our products
are available on our website.
☞Contact your distributor if you have any
questions.
Your electric wheelchair’s Operating man-
ual also includes information on product
safety as well as any product recalls that
may be in effect.

MODELS
This operating manual applies to the fol-
lowing control module:
Omni 2 Module
SPECIFICATIONS
This control module has been developed
for electric wheelchairs with R-Net electron-
ics.
USAGE
This control module must only be connect-
ed to the electric wheelchair via the R-Net
electronics.
ADJUSTMENT
As a general rule, any type of adjustment
or customisation must be performed by a
distributor.
Before you use the control module for the
first time, your distributor must adjust it.
Aside from your driving experience and
special needs, this adjustment must also
take into account the environment in which
the wheelchair primarily will be used.
If your needs or requirements change, the
distributor can adjust the sensitivity of the
joystick.
☞We recommend routine inspection of
the control module settings to ensure
optimal long-term comfort, including
whenever your medical/disability situ-
ation changes.
USE AFTER A PERIOD OF
STORAGE
The control module may be put into use
again after a period of storage. Before it is
used again, it must undergo a complete in-
spection.
☞Hygienic measures, including disinfec-
tion, must be performed in accordance
with a validated hygiene plan.
PRODUCT LIFE SPAN
We estimate that the product should have
an expected average life span of 4 years,
provided it is used for its intended purpose
and all maintenance and service require-
ments are met. The actual life span depends
on how frequently the product is used, the
environment where it is used and the care
that it receives. Replacement parts may al-
low you to prolong the product’s life span.
As a rule, replacement parts can still be ob-
tained for up to 5 years after a model has
been phased out of production.
☞This stated estimated life span shall not
be considered to constitute any expres-
sion of the warranty period.

7
SAFETY PRECAUTIONS
☞Do not throw or drop the dismantled
control module. Handle it carefully at
all times! This is the only way to ensure
continuous, error-free operation.
☞Do not unplug the connector while
driving.
☞While driving, do not press the ON/OFF
button unless it is an emergency.
– This stops the electric wheelchair
(emergency braking).
☞Do not plug any objects other than
the original equipment manufacturer’s
plugs into the connectors.– Risk of a
short circuit!
CONNECTION OF TWO
JOYSTICK MODULES
This must only be performed by the dis-
tributor.
It is possible to connect two joystick mod-
ules to the R-Net system.
This option may be helpful if an attendant
will be operating the wheelchair and the
control module does not need to be moved
to the back of the wheelchair.
Alternatively, the second joystick module
can be used e.g. instead of an external joy-
stick or external ON/OFF button. This allows
you to add more functions, such as e.g. turn
signals, a horn, etc.
Driving features are active for the control
module on which they were enabled.
The screen is displayed in this same manner
on the other control module. This control
module also allows the system to be turned
off.

PREPARATIONS FOR USE
Charging the batteries
Do not insert objects aside from the safe-
ty plug and battery charger plug into the
charging socket. – Risk of a short circuit!
To charge the batteries, first turn off the con-
trol module, then insert the battery charger
plug into the distributor box socket (14).
☞Please also refer to the Electric wheel-
chair operating manual.
Connecting the control module
Do not touch or move the joystick during
the start-up phase (lasts approx. one sec-
ond)!
Press the push button (7) to turn on the
control module. The electronics will now
perform a system test.
Once the battery indicator (22) steadily
lights up, the electronics are ready for use.
☞After the control module has been
turned on, if driving profile 8 lights up,
it means that the chair is in attendant
control mode. You can switch over to
user mode by pressing the Proles but-
ton.
☞If there is a malfunction, messages will
be displayed on the LCD screen.
☞Follow the instructions in the chap-
ter Troubleshooting on page 37.

PRE-DRIVE INSPECTION
Battery indicator
After you turn on the control module, after
a short system test, the battery indicator
(22) displays the battery charge level.
As the batteries drain, the battery indicator
will show an increasingly smaller number of
illuminated segments (22).
☞This indicator is made up of 10 seg-
ments (3 red, 4 yellow/orange and 3
green).
The colour of the segments indicates:
Green The batteries are charged.
☞The battery level corre-
sponds to the number
of green indicators that
light up.
Yellow Recharging is advisable.
Red The batteries are empty. Re-
charge as soon as possible.
☞The battery indicator is only accurate
when travelling on flat surfaces.
☞When driving up or down a gradient,
the reading will be unreliable.
Interpretation
The battery indicator has been designed for
the discharge properties of the manufactur-
er's original batteries. Aftermarket or other
batteries may have divergent properties
that negatively affect the reliability of this
display.
Moreover, since an accurate reading is con-
tingent on the age of the batteries and the
temperature and load to which they are ex-
posed, certain limitations apply.

Maximum speed setting
Risk of an accident due to:
– Inappropriately set maximum speed
level.
– Select a lower maximum speed level
while driving!
The max. speed level must be selected
according to your personal circumstances
and particular driving situation!
When driving downhill adjust the max.
speed in proportion to the steepness of
the gradient. Never exceed the maximum
allowable speed. – Risk of an accident!
When the control module is turned on, it
automatically recalls and reactivates the last
max. speed setting.
The number of segments that light up in the
max. speed indicator (26) indicates the max.
speed level setting.
☞Follow the instructions in the chapter
Buttons and symbols on page 12.
Before or while driving, pressing the Plus (3)
or Minus (5) button, respectively, increases
or decreases the maximum speed setting
one level at a time.
☞Please see chapters Speed levels on
page 22 and Buttons and symbols on
page 12in this context.
