If you have a Casio watch and no longer have the manuals, here is a site you can go to to get a pdf version of the manuals. All you have to do is to look at the back of your Casio watch and look for the module number. This is usually the numbers inside a rectangle box. Key in the number and chances are you will get your manuals. The site does not have all the manuals, new releases and some vintage models will not be there.
