2.1

Joystick

This controls the speed and direction of the wheelchair. Push the joystick in the direction

you wish to go. The further you push it, the faster the speed. Releasing the joystick

stops the wheelchair and automatically applies the brakes.
When in actuator control mode, pushing the joystick left and right will toggle selection

between the available actuators. Operating the joystick in the forward and reverse

directions will adjust the selected actuator.

Controls

Refer to the following illustration for the dual module control layout.
