That is the pic there already.........LOL.........I think he means in the place where it displays the temp...look on the left upper part...looks like something is sliding in there. I am not sure if you can take them apart or not. Are there screws on the back or anything? If you can get in there, you should be able to put it back where it belongs and secure it somehow...I have never done it though, so I have no idea for sure.
