Types Of Notifications; Procedure For Warnings And Error Messages; Wheelchair Control Unit Error Overview - Otto Bock C2000 Instructions For Use Manual

9.3.1 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.

9.3.2 Procedure for warnings and error messages

• If a warning or error message appears, the power wheelchair can often no longer be driven. In this case, the
error message must be noted, the control unit switched off and the qualified personnel informed of the error
message immediately.
• If the error is related to a component which is not currently being used (e.g. to an actuator for adjusting the
seat function), the driving function of the power wheelchair is still theoretically usable. An error message simply
appears at regular intervals.
• Nonetheless, the control unit must be switched off for several minutes in this case. If the error message contin­
ues to appear after switching on the control unit, the error message must be noted, the control unit switched
off again and the qualified personnel informed of the error message immediately.
