The electronic controller is what you use to operate your power chair. It takes the battery voltage and sends it to the appropriate system. The electronic controller enables you to move the power chair, as well as monitor battery charge, electronic controller functions, and the condition of your electrical system.Also, it may be used to control some optional systems such as power elevating seats and lights.
The VSI controller is an integral electronic controller.All of the electronics necessary to operate the power chair are contained in one module. See figure 27.
The VSI consists of:
1. joystick
2. keypad (see figure 28)

Joystick
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 further 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, you engage the electromagnetic brakes. This causes your power chair to decelerate and come to a complete stop.
WARNING! If your power chair begins to move in an unexpected manner, immediately release the joystick. Unless the joystick is damaged, this action should stop your power chair.
Keypad
The keypad is located in front of the joystick. It contains keys necessary to operate your Jazzy.
