Controller Fault

Repair of defective units

Apart from specific OEM-approved spare parts (contact Permobil for further information on these), there

are no replaceable parts in the Rnet control system. Consequently, defective units must be sent to

Permobil or a Permobil-approved repairer for repair.

If any part is replaced without Permobil’s approval, the wheelchair’s warranty lapses. Permobil cannot be held responsible for

losses of any kind arising as a result of a component of the Rnet control system being opened, adjusted or modified without

permission.
