Where installing a new doorbell in this house. Basically this is a fairly simple step now this is the new doorbell base taken and kind of put one in that hole there. Take your pliers just give it a quick tape and take this and you should be able to kind of spin it. There you have your new hole for your anchor. You just take it and slide your anchor in there, set it and there is the new anchor and do that at all 4 locations. Put your base back up, slide your wire through the holes and just take your screw driver and tighten that down. Now remember that piece of paper earlier I was telling you to write down the wire color to what terminal it is. Now if you remember the green went to F, the red went to T and the blue went to R. Now basically this is the front, the transformer, and the rear. Its just like the one that you took off earlier so we just go back with that same configuration just that blue, green, and red. You hook it on to the terminal and just tighten it down. You don't really need to tighten it really tight just snug it up and thats is how that works. Now to put the cover on you would notice that on this particular model there is a little pin at the top of a little pin at the top of this. That little pin just goes right in that hole that covers is really easy to put on it basically just hang on this unit. You find that hole, push it back and there you go your doorbell is completely installed. I'm Chad Smith and we installed today a new doorbell in this house.
