So I bought one of these chargers the other day and I like it a lot and works well, but I can't stand the fact that it's not backlight. So I started taking it apart today and I got stopped by the rotary dial/button, of which I can't get off. Does anybody know how it comes off, any help would be great.
Also incase anyone wants to know there is a ton of room behind the screen for lights but you will have to cut the plastic that is currently behind the screen, which requires taking the front plastic off, but first you have to get the rotary button off.

Thanks,
Bob
