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 controllers 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 module:
CJSM2 module
SPECIFICATIONS
This joystick module has been developed
for electric wheelchairs with R-Net electron-
ics.
USAGE
This 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 necessary, your distributor can adjust the
sensitivity of the joystick.
☞We recommend routine inspection
of joystick module settings to ensure
optimal long-term comfort, including
whenever your medical/disability situ-
ation changes.
REUSE
The joystick module may be put into use
again. Before using the joystick module
again, it must be carefully inspected.
☞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 in-
sofar as the product is used for the intended
purpose and all maintenance and service
requirements are adhered to. The actual life
span depends on how frequently the prod-
uct is used, the environment where it is
used and the care that it receives. Replace-
ment parts may allow you to prolong the
product’s life span. As a rule, replacement
parts can still be obtained for up to 5 years
after a model has been phased out of pro-
duction.
☞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.
☞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 charging socket.
– Risk of a short circuit!

CONNECTING TWO
CONTROL MODULES
This must only be performed by the dis-
tributor.
It is possible to connect two joystick mod-
ules to the R-Net LCD 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.
Alternatively, the second joystick module
can be used e.g. as an external joystick or
external ON/OFF button. This allows you to
add more functions, such as e.g. turn sig-
nals, a horn, etc.
Driving features are active for the joystick
module on which they were enabled.
The second joystick module’s screen is con-
trolled in the same manner. This joystick
module also allows the system to be turned
off.

PRE-DRIVE INSPECTION
Battery indicator
After you turn on the joystick module, after
a short system test, the battery indicator
(21) displays the battery charge level.
As the batteries drain, the battery indicator
will show an increasingly smaller number of
illuminated segments (21).
☞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.

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 on the joystick module, it
automatically recalls and reactivates the last
max. speed setting.
The number of segments that light up in the
max. speed indicator (25) indicates the max.
speed level setting.
☞Follow the instructions in the chapter
Buttons and symbols on page 11.
Before or while driving, moving the control
lever (13) forwards or backwards, respec-
tively, 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 11in this context.
