Goto http://www.casio.co.uk/Support/Services/, they should be able to advise you.

If it has "AC" written on the module you may need to short between the AC point and + battery. Also check voltage of battery. It may just be too flat.

If you see no screws holding the contact (metal frame), that means the contact is clip-on. Take an eyeglass and examine all contact legs carefully- you will find out where it is clipped on. Use fine pointed tweezers to pull contact legs and undo it.

Rate, please.

Hold down the adjust button (top right) and flick through with mode (bottom left) when you are done hit adjust again and it will take you to the next 'page' of settings. Same deal there. Use the top and bottom left buttons to change number up or down

Good luck

"AC" means All Clear. This terminal should be marked somehow. Use a magnifying glass to get a good look at what you are working on. My Casio had an arrow pointing to four copper leads. I used a paper clip to connect the AC terminal (I just picked one of the four) to the + side (usually the "up" side) for a couple seconds and my Casio Sea Pathfinder model 2273 powered right up. See the following link for more guidance.

This certainly put me on the right track,but i found on my pathfinder mod 2271 that the four brass dots located down in the hole were unacessable with standard flat head tweezers so I inserted a small sewing needle and touched one of the brass dots while bridgeing the distance from the needle to the positive (+) surface of one of the four batteries with tweezer legs.
