Hi.

Battery replacement is done removing the back plate. The back plate is uncrewed clasping it with a special tools and rotating anti-clockwise. In absence of the special tool a common pair of tweezers will do the job.

Once the back plate is off, extreme care must be taken with the rubber seal, running around the edge of the case opening. This is very delicate, and damaging or kinking the seal may result in the watch loosing its water proof capacity. For this reason battery replacement is better done at the shop.

Thanks for contacting FixYa.<br /> You can download a manual at:<br /> <a href="http://world.casio.com/wat/download/en/manual/">http://world.casio.com/wat/download/en/manual/</a><br /> best regards

The only solution here is to send it back to a Casio Authorized Service Center. I don't know if they will take care of it under warranty, unless you have some kind of Insurance policy against thief or damage. All you do is try. Good luck!

first choose in which mode you need your watch to show you time, either in analog or digital, and that can be done by using the 2 side keys i hope
