Place the SilverCrow Power Saver and Spike Arrester Card over the main switch
Optional: If you have two cards, you can put them side by side like so. That's all there is to it. Close the lid and forget about it. *Although one card will suffice, some choose to use two, and have attested saving a little more. Enjoy paying less.
*Please read the refund procedure before ordering the SilverCrow 7000 Power Saver and Spike Arrester Card.
