Joystick Control
The joystick controls the driving speed and direction of the power chair. When the joystick is at rest,
it is in the neutral (center) position, and the chair is stationary. In order to drive the chair, the joystick
must be taken out of neutral. Moving the joystick in any direction will switch the chair from neutral to
drive, and the chair will move in the direction indicated by joystick position. The farther away from the
neutral position the joystick is, the faster the chair will move in that direction. To stop chair movement,
simply release the joystick or move it back to the neutral position. The chair’s electromagnetic brakes
will engage after the chair has come to a controlled stop.
