VII. OPERATION
The Joystick
The joystick (see figure 14 on page 21) controls the speed (up to the maximum limit set
by the speed dial) and direction of your power chair.
Pushing the joystick away from the neutral (center) position will move your

Envy
in the direction that the joystick is pushed.
♦
The farther forward or backward you push the joystick, the faster your power
chair will go.
To operate your power chair, gently push the joystick in the direction in which you want
to travel.
♦
Gentle operation of the joystick will provide you with smoother changes in speed an
direction.
♦
Sharp or jerky operation of the joystick will result in quick and drastic changes in
direction and speed.
For your safety, the controller automatically sets the reverse speed,
acceleration, and deceleration in proportion to the speed control setting.
When you are not pushing on the joystick, or when you release the
joystick, the joystick will automatically return to the neutral position, the chair will
decelerate, as the electromagnetic brakes are applied, and come to a smooth stop.
Controlling Maximum Speed
The speed dial allows you to limit the maximum speed of the power chair
(that is, the speed when the joystick is fully deflected) to suit your
preference and environment.
Speed Dial
The dial offers 10 discrete steps between the lowest speed (dial set to the left) and the
highest speed (dial set to the right).
As a visual reminder, a speed symbol (shown left) is positioned just
above the speed dial to indicate the low and high positions of the
speed dial.
Speed Symbol
The horn button is located below the power button. Press the horn
button to sound the horn. The horn will sound for as long as the horn
button is pressed.
