Unsafe operation of the power wheelchair
f
Troubleshooting may thus only be carried out by authorised specialist dealers possessing solid knowledge of
electronic controllers from Ottobock.

Ottobock assumes no liability for any damages originating from improper or poorly performed repairs.
INFORMATION
Experience has shown that electrical problems are frequently associated with errors and defects in the plug con-
nectors and cabling. These areas should therefore always be examined first.
Faults that occur are displayed on the control panel or a connected handheld programming device.
All faults that have ever occurred are saved in a list and can be retrieved, e.g. in case of a general overhaul of the
power wheelchair. The saved data can be used to determine future service and maintenance intervals, for example.
5.1
Diagnostic steps
To ensure efficient and successful troubleshooting, proceed as follows:
• Ascertain whether there is a concrete error trigger or a sporadic error message.
• If applicable, read and note down the error text displayed on the control panel.
• Look up the potential cause in the error tables (see Page 127/Page 130 ff.) and carry out the recommended
inspections and corrective measures.
