JOYSTICK SWITCHES AND INDICATORS

NOTE: For the following information, refer to FIGURE 5.1.

ON/OFF BUTTON

This button is located on the joystick housing.

SPEED CONTROL KNOB

The speed control knob is located on the back of the joystick housing. This rotary knob is
used for controlling the speed and acceleration of the wheelchair.
1. Turn the knob clockwise to increase the speed of the wheelchair.
2. Turn the knob counter-clockwise to decrease the speed of the wheelchair.

JOYSTICK

The joystick has proportional drive control, meaning that further the wheelchair is
pushed from the upright (neutral) position, the faster it moves. Your top speed, however,
is limited by the setting of the speed control knob and programmed settings.
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has
automatic speed and direction compensation to minimize corrections.

INFORMATION GAUGE DISPLAY

The Information Gauge Display is located on the joystick housing. It provides the
following information to the user on the status of the wheelchair -
1. Power is on.
2. True state-of-battery-charge, including notification of when the battery requires
charging:
A. GREEN LED is lit, indicating well charged batteries.
B. Only AMBER LEDs are lit, indicating batteries are moderately charged. Recharge
batteries before taking a long trip.
C. Only RED LED is lit, indicating batteries are running out of charge. Recharge
batteries as soon as possible.
3. Program, inhibit or charge modes.
4. Fault indication (Flash Codes).
The Information Gauge display also serves as a system diagnostic device when a fault is
detected by the control module. A specific number of flashes of the LEDs indicate the type
of fault detected. Refer to the following table of the diagnostic indications of the
wheelchair status.
NOTE: The joystick must be in the neutral position for an accurate reading of battery charge.
