Step 2Breaking the seal

Breaking the seal
To open the case, you will need a (small but sturdy) sharp screwdriver or similar, preferably with a wide blade. Closely examine the groove going around it and look for what half the bottom of the groove belongs to. Typically the halves meet as shown in the pic (with the prongs facing downward).

Starting from the middle of each side, carefully pry at the angle shown while applying some inward pressure (DO NOT HAVE THE PRYING TOOL FACING ANY PART OF YOUR BODY). You may have to dig in a little, but it will eventually pop. Work left to right along the same side, then do the other, and then the narrower sides. Once you have compromised the seal on all four sides, carefully work into the corners until you can start to pry the halves apart. The idea is to try to work the pry tool through the seal, and then on top of the lip to start working the halves apart.

Be very careful not to allow the tool to penetrate too far, or you could ruin the transformer. Also be very careful not to allow the tool to slip and go into your hand or somewhere else.
