INTRODUCTION
As a pert of the electronic wheelchair
the operating module VR2 directs the
driving and control commands to the
motors and electronic.
Depending on the equipment of the
electronic wheelchair such as lighting
and or electric adjustments the corre-
sponding operating module version is
connected.
You endanger yourself and others
by an improper use of the operating
module or its accessories. The correct
handling must therefore be learned.
☞Note:
Please note that the options and
accessories are not a part of the
standard scope of supply!
The purpose of this operating manual
is to make you familiar with the han-
dling of the operating module and to
prevent accidents.
!Attention:
Read and observe this manual be-
fore first operation:
– this operating manual,
– the safety and general handling in-
structions < Electronic vehicles > as
well as
– the operating manual of the
wheelchair.
☞Note:
Children must read this operating
manual together with the parents
or supervising or accompanying
person before the first use of the
electric wheelchair.

SAFETY INFORMATION
▲Always handle a detached oper-
ating module correctly and never
throw or drop it. To guarantee
their function.
▲Do not touch the ON/OFF button
while driving. This will disable the
vehicle.
SPECIFICATIONS/ UTILI-
SATION
Use
The operating module is only to be
connected to wheelchair that has
been prepared for the according con-
troller < VR2 >.
The VR2 operating module is solely to
be used to control the corresponding
wheelchair and its additional options.
Adjustment
The operating module should be
adapted to your disability by your
dealer before the first use.
The adaptation will take into account
the driving experience, the physical
limits of the user and the main place
of use of the wheelchair.
The sensitivity of the joystick can be
adjusted by a dealer when there is a
change in the degree of the disabil-
ity.
!Attention:
You should only allow a dealer to
carry out adjustments or settings.

PREPARING THE WHEEL-
CHAIR FOR OPERATION
Recharging batteries
To charge the batteries first switch off
the operating module. Then insert the
plug of the battery charger into the
charging socket (1) on the front of the
operating module.
☞Also view < Operating manual of
the wheelchair >.
!Attention:
Do not insert other objects into the
battery charging socket.
– Danger of short circuit!
Switching the operating module
on
Press the ON/OFF key to switch on the
operating module (2). The electronic
system now performs a system test.
The electronic system is ready when
the battery indicator (3) is perma-
nently lit.
☞Note:
Do not move the joystick during
the duration of the test.
☞If a running light appears in the
display for the maximum final
speed (4), the key-lock function is
still activated.
☞see chapter < key-lock function >.

Key-lock function
In order to protect the wheelchair
from unauthorised use, it can be
locked with the key-lock function.
Switch on the Key-lock function
To switch on the key-lock function the
wheelchair is engaged.
1. Hold onto the ON/OFF-key (1) until
a signal tone is heard, only then re-
lease it again.
2. Move the joystick forward until a
signal tone is heard, only then re-
lease the joystick.
3. Move the joystick backward until a
signal tone is heard, only then re-
lease the joystick.
☞The joystick returns to the centre
(zero position) and the operating
module automatically switches off
with a long signal tone.
☞The key-lock function is then en-
gaged.
Switch off the Key-lock function
After switching the operating on a
running light appears in the display
for the max final speed / driving pro-
file (2).
1. Activate the ON/OFF-key (1).
2. Move the joystick forward until a
signal tone is heard, only then re-
lease the joystick.
3. Move the joystick backward until a
signal tone is heard, only then re-
lease the joystick.
☞The joystick returns into the centre
(zero position) and the key func-
tion is switched off after a long
signal tone.
☞The wheelchair is ready for opera-
tion again.

Evaluation
The exactness of the battery gauge
depends for example on the temper-
ature, age and strain on the battery
is therefore subject to certain restric-
tions.
The kilometric performance (range)
of the wheelchair should be tested at
least once.
PRE-OPERATION CHECKS
Battery voltage
The battery indicator displays the
battery voltage after the system test
performed by the electronic system
after the operating module has been
switched on (1).
Less LED segments of the battery in-
dicator are lit as the battery voltage
reduces.
Battery display
The battery indicator displays the ex-
isting battery voltage as follows:
The colours mean:
green = batteries charged.
☞The charging status corre-
sponds to the number of
green lit LEDs.
yellow = recharging recommend-
able.
red = batteries discharged, re-
charge without delay.
☞Note:
An accurate battery indication is
only given during travel on a level
surface.
Uphill/downhill driving causes an
inaccurate indication.

Pre-selectable maximum speed
After switching on the operating
module the last pre-selected max. fi-
nal speed resp. preselected driving
profile is shown (only one diode is lit
at a time).
By pressing the keys (1) and (2) the
pre-selectable final speed resp. driving
profile can be decreased or increased.
The display (3) shows the selected
speed step resp. selected driving pro-
file.
!Attention:
Danger of accident due to unsuit-
able setting of the pre-selected
speed!
For driving situation in which you
feel insecure, select a low final speed
resp. low driving profile, (e.g. driving
in tight spots, downhill, on ramps, in
pedestrian areas or similar).
!Attention:
The final speed resp. driving pro-
file is to be pre-selected in depend-
ence on the personal impression of
the respective driving situation!
The speed is to be adjusted accord-
ingly to the slope when driving
downhill. Never exceed the per-
mitted max speed. – Danger of
accident!
Diving speed stages:
The max. final speed can be
pre=selected in 5 speed steps resp.
driving profiles.
In speed step / driving profile 5 the
max. final speed, depending on the
version of the vehicle, is 6, 8, 10 or 12
km/h.
In speed step / driving profile 1 the
max. final speed lies 20% of the max.
possible speed.

☞1. Situation example:
Use in the home.
Required setting: low speed pre-
selection / driving profile (1).
☞Result of a pre/selection that is
too high:
Small movements of the director
result in quick acceleration. The
driver loses the control in the con-
fined space of the home.
– Danger of accident!
☞2. Situation example:
Crossing a road junction.
Required setting: high speed pre-
selection / driving profile (2).
☞Result of a pre/selection that is
too low:
The road junction is not crossed
quickly enough.
– Danger of accident due to on-
coming vehicles!

JOYSTICK
!Attention:
Only move the joystick when the
battery indicator (2) shows a con-
stant light.
Drive and steering movement
The wheelchair is accelerated and
braked with the joystick. Move the
joystick (1) slowly in the desired driv-
ing direction.
The further you move the joystick
away from the centre position, the
faster the wheelchair will travel (up to
the pre-selected maximum speed).
A simultaneous lateral deflection of
the joystick causes a curve travel.The
wheelchair will turn almost on the
spot if the joystick is only deflected
sideways.
☞Note:
The speed is reduced automatically
during reverse or curve driving.
Braking the wheelchair
The wheelchair stops when you let go
of the joystick.
For allotted braking slowly guide the
joystick back to the centre position
(zero-setting).

For driving situation in which you feel
insecure, select a low final speed resp.
driving profile, (e.g. driving in tight
spots, downhill, on ramps or similar).
!Attention:
During downhill driving, the speed
must be reduced and adjusted to
the respective gradient.
Pre-select the maximum speed
When pressing the key (1) before or
while driving the pre-selectable maxi-
mum final speed resp. driving profile
is increased by one step up to max step
5. Step 1, the lowest final speed resp.
driving profile, automatically follows
step 5.
☞Note:
The diode (LED) that lights up in
the display (2) indicates the select-
ed speed step / driving profile.
!Attention:
Danger of accidents due to unsuit-
able selection of the pre-selectable
final speed resp. driving profile!
•The final speed resp. driving profile
is to be set in accordance with the
personal abilities of the attendant
in the respective driving situation!
•Changing into a lower speed stage
may only be done during a still-
stand of the wheelchair.
