Battery voltage indicator
Each time the wheelchair is started, parts of the wheelchair's electronics are checked. If any fault has
occurred in these parts, this is displayed on the control panel's battery voltage indicator and the indicator
for speed/driving profile in the form of one or more flashing lamps.
Troubleshooting and repairs must always be performed by competent personnel with good knowledge
of the wheelchair's electronics. More information on troubleshooting and remedies can be found in the
service manual for this wheelchair model.

batteries. If the batteries are fully charged, all the lamps light up.

The batteries need to be charged immediately.
Flashing fast, 1 - 10 lamps
A fault has been detected in the wheelchair's electronics and the wheelchair cannot be driven.

• Check that all visible cables and the cable to the control panel are connected correctly.

a possible cause and remedy in the table on the adjoining page.
Do not use the wheelchair until the problem has been remedied or you have received other instructions
from your service contact.
