No LEDs Illuminate
First, double check to make sure the unit is plugged into an AC outlet. Check if the AC outlet has power. If the AC outlet has no or limited power, it could cause this condition. Plug a light into the AC outlet to check if the outlet has power. If the light is extremely dim, this could be the result of limited AC power. The battery charger is designed for use at 100-240VAC. If there is no power or the power is below 100VAC, locate another AC outlet that has sufficient power to resolve this ERROR condition.
