7.5 “5 Speed” and “VSP” modes
Shark II supports 2 modes of top speed adjustment – “5 Speed” and “VSP” modes.
In the “5 Speed” mode pressing the Increase Speed and Decrease Speed buttons steps between
one of the 5 top speeds 20% to 100%.
In the “VSP” mode a quick single press of the Increase Speed and Decrease Speed buttons also
steps between one of the 5 speeds 20% to 100%. However, pressing and holding the Increase
Speed (Decrease Speed) Button ramps the top Speed up (down) in fine steps, allowing practically
any top speed to be selected. This can be particularly useful for matching the chair speed to the
walking speed of an accompanying pedestrian.
VSP is an extremely powerful feature, allowing both fast stepping between fixed top speeds by
using quick presses or finer control using long presses. The VSP feature can be enabled or
disabled. Users can toggle between the “VSP” and “5 Speed” Modes by holding down both the
Increase Speed and Decrease Speed Buttons for approximately 2 seconds while the unit is
powered up. The control unit will beep when the mode has been changed.
