=============
Bistable mode works after a fashion but I always get a bright background
whatever settings I use. The trace is quite visible but I suspect something
may be out of spec. 'Fast Bistable' mode is not usable, with the eye of
faith you might convince yourself there is a trace on the screen but not
useful.
=============
Your scope is just fine. Forget about bistable entirely - the contrast is
lousy, and the background always bright. Since the "first use" in the
manual is based on bistable mode, most scopes have got a trace burn on the
storage mesh as first time users desperately tried to get some trace
contrast by cranking up the brightness. Check the archives for this.
Just use the variable persistence and fast variable persistence modes and
you will be a happy bunny.
