There is no need to save your note, it is saved as you work - just exit when finished. Unfortunately this also means that there is no way to undo a mistake by reverting to a previously saved version. You may wish to now try transferring your Note to a friend's calculator over the infra-red link using the and keys. Corrupting notes An occasional problem users encounter is finding that the Notes they have saved onto a computer are corrupted when they try to read them back. This is almost invariably caused by trying to open, read, print or otherwise tamper with the Note while it is on the computer. If you view the file once it has been stored by double clicking on it to try to open it then the computer may try to edit it with one of the word processors you have installed. If you allow this and save the result then all sorts of characters will be inserted into the file that will make it unreadable by the calculator. If you find that you have unintentionally opened a file in this way then exit from the word processor without saving. Calculator Tip Only the proper software should be used to edit Notes on a computer. 183
