HP handheld (old) calculator 41cv


can anyone tell me how to clear my calculator read out?..
I have an old HP 41cv



my first answer was a bit vage, so I decided to rewrite it.

What do you want to: clear display contents or physically clear the display for dirty?

If you want to reduce display contents to 0.0000, simply press

[SHIFT] (yellow key) [<-].

If you want to remove dirty from inside the LCD display, meaning you have some sort of dirty on it, the best way is by openning the calculator and using air. People from this very site have exhaustively discussed this particular subject many times, and many of them can guide you to accomplish this task. Do you ned assistance on this?

Best regards and success.
