Turning the SHARK on and off
To turn on the SHARK
Press the on/off button.
All Battery Gauge LEDs turn on one by one.
After the SHARK has started up successfully, the Battery
Gauge shows the charge of the battery.
To turn off the SHARK
Press the on/off button.
The SHARK turns off.
If the on/off button is pressed while the chair is driving,
the chair will perform an emergency stop before it
turns off.
Out Of Neutral At Power Up (OONAPU)
+
If the SHARK is turned on while the joystick is not in the
centre position, an “Out Of Neutral At Power Up”
fault occurs.
During an OONAPU fault the speedometer LEDs
flash continuously and the chair will not drive.
As soon as the joystick is released back to the centre,
the fault goes away and the chair will drive normally.
OONAPU is a feature that prevents sudden and unexpected powerchair movements if
the joystick is out of the centre position when the controller is turned on.
Warning:
If an OONAPU error does not go away after the joystick is
released, the SHARK may be damaged. Do not use the
powerchair and consult a service agent.

6 The SHARK system
Using the SHARK Lock
If the Lock Enable parameter is set to 'Yes', the SHARK can be locked by pressing the
on/off button for more than 4 seconds. Lock the SHARK to prevent unauthorized
persons from operating the chair.
To lock the SHARK
Press the on/off button for 4 seconds when the SHARK is turned on.
The SHARK turns off immediately when the
on/off button is pushed.
After 4 seconds all LEDs of the battery gauge will flash
twice and the horn will give two short beeps,
to indicate that the SHARK is now locked.
To unlock the SHARK
Press the on/off button.
The SHARK will turn on, and the LEDs of the battery
gauge will slowly flash from right to left to indicate that
the SHARK is locked.
Press the horn button twice within 10 seconds.
The SHARK will turn on normally.
If the horn button is not pressed within
10 seconds, the SHARK will turn off again.
Waking up from Sleep Mode
The SHARK will go to sleep after a period without joystick movement.
This period can be set with the Sleep Timer parameter. When the SHARK sleeps, it is
partially turned off to reduce energy consumption and to make sure that the
powerchair does not move when the user accidentally moves the joystick.
To wake up the SHARK
Press the on/off button only*, or
press any button on the SHARK or move the joystick**.
The SHARK turns on.
When a programmer is connected to the SHARK, the SHARK will not go to sleep.
If the SHARK goes to sleep during charging, the charging of the battery will continue.

Driving
Using the Joystick
Move the joystick.
The powerchair starts to drive in the direction of the joystick movement.
The amount of joystick movement determines the speed
of the powerchair. If the joystick is moved further from the
centre, the powerchair will drive faster.
Adjust the maximum drive speed
You can adjust the maximum speed of the chair to your preference
or environment. The currently selected top speed is shown on the Speedometer.
Using the Speedometer
The function of the Speedometer depends on the value of the
Speedo Display parameter.
Max Speed Only
The speedometer shows the maximum speed that
has been set with the speed buttons.
Speedo Plus Max Speed
The speedometer shows the current chair speed together with
the maximum speed that has been set with the speed buttons.
When the joystick is deflected and the speed of the chair
increases, the LEDs will turn on one by one until the maximum
speed (that has been set with the speed buttons) is reached.
If the bottom-left GREEN LED is flashing, SHARK is in speed limit
mode. This happens when the chair is in an unstable position
and driving too fast may be dangerous, for example when
the seat is raised or tilted. See the Installation Manual of the
SHARK Power Module for further details on how to limit the
speed when the chair is not stable.

Using the Horn
Press the horn button.
The horn will sound as long as the button is pressed.
Reading the Battery Gauge
Battery charge indication
The Battery Gauge indicates how much battery charge remains.
The remaining battery
capacity does not translate
directly to remaining
physical range of the
powerchair. The remaining
physical range depends on
the ambient temperature,
the capacity and age and
state of the battery, the
driving style of the user and
the terrain that the
powerchair is being used in.
Most of these factors can
vary between, or within,
one journey.
Other indications
Apart from the remaining battery charge, the Battery Gauge also indicates the following
conditions.
Battery Gauge
Meaning
Drive Inhibit, the chair will not drive.
For example, when a charger is connected to the SHARK.
The LEDs turn on one by one from left to right.
A fault has occurred.
All LEDs turn on one by one from left to right to indicate that the
chair will not drive. The Fault Indicator LED will show the
corresponding Flash Code.
Flash Code 2 fault: battery too full.
Slow down if you are driving down a slope.
Turn on the lights, if fitted.
Battery Gauge
Meaning
Battery full.
Battery half full.
Start the return journey.
Battery low.
Recharge soon.
Battery almost empty.
Recharge now.
Flash Code 2 fault: battery completely
empty. Battery damage will occur if you
keep on driving. Recharge immediately.

Battery charging
The 3-pin XLR battery charging socket is located on
the front of the SHARK. If the chair has an On-board
Battery Charger (OBC), plug the OBC power cable
into a power outlet. The powerchair does not drive
when the batteries are being charged. Only use the
battery charger provided by your dealer.
When the SHARK is turned on during charging, the
LEDs of the battery gauge will swap between showing
the approximate battery charge, and turning on one
by one from left to right to indicate that the
powerchair will not drive.
When the Battery Charger shows a „full‟ battery charge, you can remove the charger from
the SHARK. Do not use the indication on the battery gauge. Only use the indication on the
battery charger itself to see when charging is complete.
Using the Seating Functions
In the Seating Mode the joystick does not drive the chair; it selects and operates the
seating functions instead.
Activate the Seating Mode
Press the Seat Function button to activate Seating Mode.
The Seating Mode starts with Seat Function 1 selected
(If Seat Function 1 is enabled.).
The '1' on the Seat Function button becomes illuminated.
Charging
Socket
Note:
1. It is recommended to leave the SHARK off while charging when
possible. A load during charging (for example, the use of seating
functions) causes a temporary voltage drop in the battery. This
causes some battery chargers to think that the battery is still empty
while it is actually fully charged. Depending on the specifications of
the battery charger, this can result in overcharging and possible
battery damage. Read the manual of your battery charger for
more information.
2. Overcharging dramatically decreases the lifespan of a battery.
3. If SHARK is turned off or goes into sleep mode while charging,
charging will continue.

10 The SHARK system
Select the Seat Function
Press the Seat Function button or move
the joystick right to select Seat Function 2.
Move the joystick left
to select Seat Function 1.
Operate the Seat Function
Move the joystick forward to operate the Seat Function in one direction.
Move the joystick in reverse to operate the Seat Function in the
opposite direction.
If you move the joystick further away from the centre position, the Seat
Function moves faster (if the Seat Control Type parameter is set to
„Proportional‟).
Return to the Driving Mode
Press the Seat Function button until both
'1' and '2' are not illuminated to return to
Driving Mode.
Using the Lights
To operate the lights
REMD21
REMD31
Press the side light button to switch the side/positioning lights on or off.

How to set the speedometer
If your SHARK remote has a speedometer display, it can be used in two different display modes:
Max Speed Only, or
Speedo Plus Max Speed.
Max Speed Only Display
If the speedometer is set to display Max Speed Only, the
speedometer shows the maximum speed that has been set
with the speed buttons.
Speedo Plus Max Speed Display
If the speedometer is set to display Speedo Plus Max Speed,
the speedometer shows the current chair speed together
with the maximum speed that has been set with the speed
buttons. When the joystick is deflected and the speed of the
chair increases, the LEDs will turn on one by one until the
maximum speed (that has been set with the speed buttons)
is reached.
To set the remote to display the speedometer with either
Max Speed Only, or Speedo Plus Max Speed, use the Wizard
to set the General Settings parameter “Speedo Display” to
either Max. Speed Only or Speedo plus Max. Speed (see
figure below).

How to use the virtual speed pot
The SHARK remote uses the speed buttons as a virtual speed pot. These can
be used to increase and decrease the speed of the powerchair in both
standard steps, and fine steps. Using fine steps can be particularly useful for
matching the chair speed to the walking speed of an accompanying
pedestrian.
To increase / decrease the speed
Slower
Press and release the „slower‟ button to decrease the
maximum speed of the chair by 20 %.
Press and hold the „slower‟ button to decrease the
maximum speed of the chair in fine steps*.
Faster
Press and release the „faster‟ button to increase
the maximum speed of the chair by 20 %.
Press and hold the „faster‟ button to increase the
maximum speed of the chair in fine steps*.
The Speed Button Sensitivity parameter sets how quick the maximum speed increments or
decrements when a speed button is held down.
* If adjusting the speed in fine steps does not work, simultaneously hold down the „slower‟
and „faster‟ buttons for 2 seconds to activate fine speed control. The SHARK will beep
when the mode has been changed.

14 How to…
How to improve load compensation for low speeds
Load compensation automatically compensates for changes in motor speed when the chair
drives over loads such as sidewalks, curbs or slopes. If the chair performs poorly on carpet or at
low speeds, the most probable cause is a Load Compensation value that is set too low.
The table below shows the behaviour and effects on a powerchair system for different values of
Load Compensation.

life
To improve load compensation for low speeds, set the value of the Load Compensation
parameter to the correct motor resistance value of the used motor. The Load
Compensation parameter can be found by connecting the SHARK system to a PC or
laptop, and running the Wizard application. Read the program from the connected
controller by pressing the Wizard button shown to the left.

How to… 15
The Load Compensation parameter is located in the Drive Programs section (see figure below).
How to change Load Compensation
To change the Load Compensation value, click on one of the
Program columns for Load Compensation as outlined in red in the
figure above. Change the value by typing in a new value. Finally,
press the „Write to controller‟ button (see image right) at the top of
Wizard to write the new program to the controller.
How to set Load Compensation to the correct value
1. Set Load Compensation to 20.
2. Write the new value to the controller.
3. Drive the powerchair onto a slope.
4. If the powerchair rolls back after it has stopped on the slope increase the Load
Compensation.
5. Write the new value to the controller.
6. Repeat steps 3, 4 & 5 until the powerchair does not roll back.
Notes:
1. This test procedure can cause the motor to become hot. For
this reason, the resulting value for Load Compensation is too
high. Reduce the found Load Compensation by 20 %, and
perform a driving test when the motors are cold to make sure
that the powerchair is still comfortable to drive.
2. A new motor usually has a higher motor resistance than a
motor that has been used for some time, because the motor
brushes that are inside the motor do not make optimal contact
until they are "worn in". If possible, perform this procedure when
the motor has been used for several hours.

16 How to…
How to configure a short-throw joystick
If the powerchair user has difficulty moving the joystick to full deflection, then the joystick can be
re-configured for short-throw operation.
Normally the SHARK controller will drive at full speed only when the joystick is pushed as far as it
can mechanically go, that is, when it hits the restrictor plate.
To reduce the amount of deflection required of the joystick, set the Joystick Throw parameter in
Wizard to:
Short, or
Very Short
Setting Joystick Throw to Short or Very Short increases the sensitivity of the joystick so that less
movement of the joystick is required to generate full speed. This can be useful to allow users with
very little hand movement full proportional control.
When Joystick Throw is set to Short, the user
only needs to push the joystick to 50% of its
normal deflection to obtain full-speed.
When Joystick Throw is set to Very Short,
the user only needs to push the joystick to
33% of its normal deflection to obtain full-
speed.
The Joystick Throw parameter can be
found under the General Settings section in
Wizard, as shown below.
Warning:
Setting
Joystick Throw to Short or Very Short can introduce a
safety
risk
, because the mechanical restrictor plate does not restrict the
movement of the joystick anymore before full forward or turn
speeds are achieved. It may be possible to demand full forward
speed and full turn speed at the same time. This can be
dangerous.

How to read powerchair-specific information
It is often useful to know the details and history of a powerchair system, especially for
maintenance or fault finding purposes. In this section of the „How to…‟ we will show you
how to obtain information for both the Remote and Power Module, such as:
Serial numbers
Time powered up
Number of times driven
Software versions
Diagnostics
To read this information, simply connect your PC to the powerchair remote and open the Wizard
application. At the top-right of Wizard you will see an icon with a wrench as shown in the image
above. Click on this icon once, and the Wizard will read the system‟s diagnostic information.
Scroll down the screen until you get to the System Information section (see image below) to see
the powerchair-specific information.

18 How to…
How to swap an active program in the field
The active Drive Program defines the driving performance of the powerchair; in the SHARK
power module, three default programs have already been defined for you.
If the active program does not suit your user, then you can quickly change the active Drive
Program using the HHP (see steps 1 & 2 below). Furthermore, once you have chosen the most
appropriate Drive Program, you can then (optionally) customise it further, using the HHP, for
each user (see step 3).
Step 1 –select Technician mode
Connect the HHP to the powerchair, and switch the
powerchair on. You will be presented with the HHP start-
up screen with the four soft-keys (LANG, PROG, DIAG, and
TECH) at the bottom of the display. Press the TECH soft-
key to enter the Technician mode.
Step 2 –enter password
Enter the password (262) using the D1-D3 soft-keys. Press
the OK soft-key when the password has been entered.
After pressing OK, the start-up screen will be shown again.
Step 3 –select Program mode
Now that we have technician access, press the PROG
soft-key to access the Program mode.
Step 4 –select the active program
In Program mode, notice that the soft-keys have changed to: EXIT, NEXT, and SWAP.
The current Drive Program is also displayed. In the example below, it is called “RWD - 1”.
To swap an active program,
simply press the SWAP soft-
key.
In the example below, the Drive Program was originally set to the default program
called “RWD – 1”. After pressing the SWAP button once, the Drive Program is set to
“RWD – 2”. Pressing SWAP once more sets the active program to “RWD - 3”.
When you have chosen the Drive Program, press the EXIT soft-key to finish.

How to… 19
Step 5 –customise Drive Program (optional)
Each Drive Program can be customised further using the HHP, to suit your user‟s needs.
After you have selected the appropriate Drive Program (steps 1 - 4, above), cycle the
power on the controller to exit the Technician mode.
Press the PROG soft-key to enter the Program View/Edit mode, and then press the YES
soft-key to enter the edit mode.
This will enable you to view and edit the following parameters:
