Thanks.
They don't have the actual manual for this older unit with analog
controls but I left a message requesting one and we'll see what they
come up with.
In the meanwhile it appears that their basic models and functions
haven't changed much over the past decade or so and so I have
downloaded the manual of the current model that appears the closest
match. The cooking instructions are pertinent but the controls (being
digital) are different.

But by trial and error I am getting there. slowly. (who would have
guessed for instance that to set the time you hold down all three LH
buttons simultaneously?)

So, the only real mysteries remaining a
- how does the self cleaning function work on this unit (apparently
that "hand" symbol switch is actually a "flame" and has to do with self
cleaning.)
- what the "R" setting stands for at the high end of the temperature
dial.
- what the "sun" symbol stands for at the low end of the temperature
dial (probably means "light on, no heat at all")
