The flashing battery light is an indication that the system is attempting to charge the battery. The orange light indicates a problem charging one of the battery cells. This usually means that the battery either needs to be recalibrated or replaced. To recalibrate the battery just use the system until the battery is dead, then recharge and repeat the process twice, after which time the battery should be recalibrated. If this doesn’t fix the flashing orange light then the battery may need to be replaced.
