9.3 Out Of Neutral At Power Up (OONAPU)
An Out Of Neutral At Power Up (OONAPU) condition occurs if the joystick is not in the
centre position when the DX System is switched on, or when an inhibit condition is
removed (for example: a battery charger is disconnected). This makes sure that the
powerchair does not suddenly start to drive.
If an OONAPU condition exists, the System Status LED flashes constantly. The
powerchair does not drive. If the joystick is returned to the centre within 4 seconds,
the OONAPU condition disappears and the powerchair can drive normally. If the
joystick is not returned to the centre within 4 seconds, the OONAPU condition will
become a latching fault. To clear a latching fault, the user must switch the DX System
off and then on again.
If a user can not easily release the joystick back to the centre, use the

9.4 Diagnostic tools
Hand Held Programmer (HHP)
When you plug an HHP into the DX System when an abnormal
condition exists, the HHP will display the detected fault on its
screen.
The PC-based Wizard program
Wizard is the preferred diagnostics tool in the workshop
environment. The Wizard provides a full fault history and
shows any current faults.
If after analysing the data, the condition cannot be
diagnosed, it is possible to print, or preferably save and
e-mail a Status Report for further analysis or distribution to
a service centre.
