• If the LEDs on the battery gauge are stepping up (i.e. the number of LEDs lit quickly increases then
resets to 1), the battery charger is connected and the wheelchair drive inhibited.
• If the battery gauge is flashing slowly then the wheelchair is operating normally, but the batteries
need recharging as soon as possible.
• If the battery gauge LEDs are flashing rapidly this indicates a fault with the wheelchair. If you have a
problem with your wheelchair consult the table overleaf. If the problem persists after you have
followed the advice overleaf then restarted the wheelchair, contact your dealer.
