How do I get a manual for a ms100 Solton Keyboard?

SOURCE: solton ms60 keyboard... volume stuck , can't adjust sound once set

There are a number of ways to adjust the volume. 1) Normally a button or keys on the keyboard will adjust the sound volume. You might have to press and hold the FN key or the Alt key then hit the key that adjusts the volume up or down. 2) If you right click on the megaphone at the bottom right near the time you can adjust the volume. If you click Start/Control Panel and look for Sound and Audio Devices you can adjust it there. 4) If you click Start/Programs/Accessories/Entertainment you will see a way to adjust the volume.
