I believe the module number for that model of Casio watch is actually 593.
Here is a direct link to the ONLINE USER'S MANUAL for that model:http://www.usersmanualguide.com/manuals/casio/qw415,587,590,593,595,596.pdf
To view the Owner's Manual with Operating Instructions just use your mouse to click on the link, which is the underlined and blue highlighted text just above.
This will open a new web browser page automatically for you and allow you to view the information at the website indicated and the contents of the Owner's Manual.
You may need ADOBE READER installed on your computer to read PDF documents, although many computers already have this type of utility pre-installed.
You can download this free at WWW.ADOBE.COM
Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there, then follow the onscreen instructions to install the software on your computer.
I hope that was helpful to you, but please don't use it to blow anything up, lol.
Good luck and take care.
