DIAGNOSTICS
Note:
SHARK is not user serviceable. Specialized tools are necessary for the repair of any SHARK component.
INTRODUCTION
A flashing SHARK information gauge indicates there is an abnormal condition somewhere on the powerchair. The
components that SHARK provides fault information for include, the motor, the park brakes, the batteries, the
cabling and the SHARK modules themselves.
Note that joystick OONAPU (Out OF Neutral At Power Up) is not a fault. Simply by removing your hand from
the joystick and allowing it to return to the neutral position, the fault will immediately clear.
The nature of the abnormal condition is indicated by a flash code. This is a sequence of flashes, separated by a
pause, followed by a repetition of the sequence. The number of flashes relates to the condition. For instance, four
flashes of the SHARK information gauge, a pause, followed by four flashes, etc. indicates a right motor fault. Five
flashes would indicate a left park brake fault.
Depending on the severity of the condition, the powerchair may or may not allow driving. In some cases the chair
may be allowed to drive but in a reduced speed ("limp") mode.
DIAGNOSTICS & FAULTS
Flash codes indicate the nature of an abnormal condition directly from the
