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.
The electric wheelchair is controlled via the
joystick module.
☞Accessories and extra features such as
e.g. external push buttons are not part
of the standard delivery.
If you use the joystick module or its acces-
sories inappropriately, you may put yourself
or others at risk, therefore, it is important to
learn to use the equipment properly.
This operating manual will help you get
comfortable using the joystick 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 joystick modules:
JSM <LED> joystick module
CJSM <LCD> joystick module
Attendant module
SPECIFICATIONS
The joystick module has been developed
for electric wheelchairs with R-Net electron-
ics.
USAGE
The joystick module must only be connect-
ed to the electric wheelchair via the R-Net
electronics.

6
ADJUSTMENT
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.
As a general rule, any type of adjustment
or customisation must be performed by a
distributor.
Before you use the joystick 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 joystick module settings to ensure
optimal long-term comfort, including
whenever your medical/disability situ-
ation changes.
USE AFTER A PERIOD OF
STORAGE
The joystick module may be put into use
again. Before any reuse, the module must
be thoroughly inspected for any defects or
malfunctions.
☞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 indicated estimated life span shall
not constitute any expression of the
warranty period.
SAFETY PRECAUTIONS
☞Do not throw or drop the dismantled
joystick 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.
☞When driving, only press the ON/OFF
button in an emergency.
– This stops the electric wheelchair
(emergency braking).
☞Do not plug any objects aside from the
manufacturer’s original charger plugs
into the joystick module charging sock-
et.
– 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 electric wheelchair
and the joystick module does not need to
be moved to the back of the wheelchair.
The second joystick module can be used for
other functions, such as e.g. an external joy-
stick or on/off button, turn signals, a horn
etc.
The joystick module that is turned on will
be set on Drive mode.
Both joystick modules show the same dis-
play concurrently. Either of the joystick
modules can be used to turn off the wheel-
chair.
In the top left corner, you can see which
joystick module is active. See point 25 on
page 10

ty plug and battery charger plug into the
charging socket. – Risk of a short circuit!
To charge the batteries, first turn off the joy-
stick module and plug the charger into the
joystick module’s charging socket (2), then
plug the power cord into the wall socket.
☞See also Electric wheelchair operating
manual.
Turning on the wheelchair
Do not touch or move the joystick during
the start-up phase (lasts approx. one sec-
ond)!

of lights in the battery indicator (17) or
pre-set maximum speed indicator (19),
respectively, indicate various error mes-
sages or information. – Follow the in-
structions in the chapter Troubleshoot-
ing on page 34.
☞If the pre-set maximum speed indicator
fails to light up when the wheelchair
starts up, it means that the chair is in
attendant control mode. – Follow the
instructions in the chapter Attendant
control on page 25.
When you have finished driving, turn off the
joystick module by pressing the on/off but-
ton (9). This disables the electric wheelchair.

PRE-DRIVE INSPECTION
Battery indicator
After you turn the joystick module on, after
a short system test, the battery indicator
(17) displays the battery charge level.
As the batteries drain, the battery indicator
will show an increasingly smaller number of
illuminated segments (17).
☞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 reliability.
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.

Pre-set maximum speed
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 you turn the joystick module on, it
automatically recalls and reactivates the last
max. speed setting.
The number of diodes (LEDs) or segments
that light up in the pre-set max. speed indi-
cator (19) indicate the max. speed level set-
ting.
Before or while driving, pressing button (6)
or (12), respectively, increases or decreases
the maximum speed one level at a time.
☞Please see chapters Speed levels on
page 22 and Buttons and symbols on
page 12 in this context.
