to the programmed max speed.
Joystick
The joystick has proportional drive control, meaning that the further the joystick is
pushed from the upright (neutral) position, the faster the wheelchair or seat moves. Your
top speed, however, is limited by the programmed settings.
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has
automatic speed and direction compensation to minimize corrections.
Charger/Programming Input
The charger/programming input is located at the front of the joystick housing. This
provides easy access for charging the wheelchair batteries. This port also serves as the
Remote Programmer Communication connection. Driving is prevented while the system
is charging.
LCD Display Screens
The LCD Display is located in front of the joystick and provides information on the status
of the wheelchair through a backlit display. The LCD display is readable in both bright
sunlight and complete darkness.

progressively disappear until no segments appear between E and F. At this level, the user
should charge the batteries as soon as possible.

displays current data on the wheelchair.
