INFORMATION
The control unit of the product switches to a safe mode at
elevated temperatures and after driving uphill for extended
periods of time, limiting the performance of the product.
The user is able to drive the product out of a hazardous
situation at any time. The product is fully functional again
once the unit has cooled down sufficiently (this may take
several minutes depending on the ambient temperature).
The power wheelchair is controlled by moving the joystick:
• The further the joystick is deflected from the centre posi­
tion, the faster the power wheelchair will drive in this dir­
ection.
