and also gives the status of the battery, the controller and the wheelchair electrical
system.

system OK.

Joystick
Controls the speed and direction of the wheelchair. Push the joystick in the direction
that you wish to go. The further you push it, the faster the speed. Releasing the joystick
stops the wheelchair automatically.
Maximum Speed/Profile Indicator
This is a gauge which shows the maximum speed setting for the wheelchair or, if the
control system is programmed for a drive profile, the selected drive profile.
To change speed/profile you must press the MODE button.
If the mode button is pressed while you are driving the maximum speed setting will be
increased by one step. Each successive operation of the mode button will increase the
setting. There are five settings and the system will toggle to the next setting each time
the mode button is pressed while driving. E.g 1-5 and 5-1
If the MODE button is pressed when the joystick is centred – when chair is stationary
– the control system operation mode will be changed. There are three modes – drive,
speed adjustment and actuator adjustment.
