### Technological Characteristics and Substantial Equivalence

### Device Description:

Operation may be either manual, using a hand lever, or with a powered version option, via a separate control on the controller unit. The powered height adjustment can not be made while the power chair is driving in any direction. The Base is a profiled and of folded sheet steel fabrication, to which the two drive motor/gearboxes, two drive wheels, five castor wheels and a footrest assembly are mounted directly.
