The speed control knob is located on the side of the joystick housing.
1. Rotate the knob clockwise to increase the speed of the wheelchair to the programmed
max speed.
2. Rotate the knob counterclockwise to decrease the speed of the wheelchair to the
programmed max speed.

Joystick

The joystick provides proportional drive control of speed and direction.

LCD Display

The LCD Display is located in front of the joystick and provides information on the status
of the wheelchair through a 2 line by 12 character length backlit display. The LCD display
is readable in both bright sunlight and complete darkness.
During normal operation the active drive is displayed on the left half of the first line. The
left half of the second line shows the Battery Gauge Display (BGD). It provides
information on the remaining charge in the batteries. At full charge, solid blocks fill in all
five segments between E (Empty) and F (Full). As the battery becomes discharged, the
furthest right segments will progressively disappear a half bar at a time until no segments
appear between E and F. At this level the word RECHARGE will appear on the second
line to indicate that the user should charge the batteries as soon as possible.
The right half of the display is the Information Center. The Information Center displays
current data on the wheelchair. FIGURE 5.8 shows the factory default odometer display.
The top line shows the unit of measured MI (miles). The second line is the value, 0000
(total miles driven).
The Information Center can display:
