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.
