Types Of Notifications; Wheelchair Control Unit Error Overview - Otto Bock Skippi Instructions For Use Manual

Maintenance and repair
If the measures described here do not resolve the faults completely, contact your specialist dealer. The specialist
dealer is able to read the exact error codes with a handheld programming device and can perform a targeted sys­
tem analysis.
The control unit stores a list of all faults that occur. The specialist dealer reads this information, for example during
a general overhaul of the power wheelchair. Based on the saved data, the specialist dealer determines future ser­
vice and maintenance intervals.

9.4.1 Types of notifications

Warning
A warning indicates a status or malfunction of one or several components of the power wheelchair. The function of
components without errors is not restricted.
For example, if the connection between the control unit and seat motor is faulty, this error will only be indicated if
the user attempts to activate the motor. However, the driving function is still available.
Error
An error affects one or several functions of the power wheelchair. The power wheelchair and its functions are not
fully operational until the fault is resolved.
