Joystick Control
The joystick controls the direction and speed of your power chair. When you move the joystick from the
neutral (center) position, the electromagnetic brakes release and allow your power chair to move. The
farther you push the joystick from its neutral position, the faster your power chair moves. When you
release the joystick and allow it to return to the neutral position, the electromagnetic brakes engage and
the power chair comes to a complete stop.
Keypad
The keypad is located directly in front of the joystick. It contains keys that you will use to control your
power chair. See figures 5, 6, and 7.
On/Off Key
The on/off key turns the system on and off.
WARNING! When faced with an emergency stop situation, release the joystick, then press the on/
off to stop the power chair. Use caution. Be advised that pressing the on/off button may cause the
power chair to stop abruptly.
WARNING! Always turn the power off when you are stationary to prevent unexpected movement.
