Casio - WK-1630/1600 - Battery

The Casio WK-1600 and WK-1630 - Battery

requires a soldering job for battery installation, which may be best left to a qualified technician. If a brave do-it-yourselfer is up for the task, it's important to use a heatsink and make quick solder joints to avoid overheating that could potentially cause the battery to explode. After the battery is installed, a certified technician should be able to get the job done quickly. Be sure to save all your programs and sequences ahead of time, as removal of the battery will cause the keyboard to revert to its original factory settings.
