To erase the notes written on the writing tablet of the NEWYES 991ES Scientific Calculator, you can simply press the delete button. This will clear the entire screen and remove all the written content. Additionally, there is a lock feature (LOCK KEY) that allows you to keep notes or information displayed on the tablet until you choose to clear it. This can be useful if you want to temporarily preserve your notes without the risk of accidentally erasing them. Please refer to the User's Guide for more detailed instructions and illustrations on how to use the delete button and lock feature effectively.
