Joe, writing changes on sheet will write the changes you made on the sheet
on the screen. Writing changes on all sheets is handy if you make a lot of
changes on different sheets, such as if you changed values on the sound
sheet and the CV sheet and speed table sheet. You can make all the changes
you want on any pages, and then click write changes on all sheets. Just
makes things a bit easier than making a change on sheet one, writing that
sheet, then making changes on sheet two and writing that sheet.
Another thing you may want to do when you add a new locomotive to your
roster, once you have made all the changes you want to make, and written
the sheets, is to have DecoderPro read all sheets. That way, all of your
setting are saved by DecoderPro, and if you decoder looses its mind, you
can go to DecoderPro had have it rewrite everything to your locomotive.
Especially helpful if you do a lot of complicated changes from the factory
settings.
