If you want to warm the calculator in sunlight, it would be best to turn it face down first.

Thanks Mark, I'll add that to my comment above.

When I got the initial advice from Michael about using an oven for one of my Voyager models, I used direct sunlight and it removed the blemish in about an hour, with no side-effect. But this suggestion that UV can do damage is troubling, so face-down does indeed make sense.

Thanks for the research and helpful suggestion.
