The Joystick
The powerchair starts to drive 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.
Adjusting Driving 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.
Press and release the “SLOWER” button to
decrease the max speed of the chair by 20%.
Press and hold the “SLOWER” button to decrease
the max speed of the chair in fine steps*.
Press and release the “FASTER” button to
increase the max speed of the chair by 20%.
Press and hold the “FASTER” button to increase
the max speed of the chair in fine steps*.
*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.
Using fine steps can be particularly useful for matching the chair speed to the walking speed of an
accompanying pedestrian.
The Speed Button Sensitivity parameter sets how quick the maximum speed increments or
decrements when a speed button is held down.
