1. When activated, the current time is displayed.
2. Use the numeric keys to enter the number you want to write down.
3. Press OK to record the time and the entered number.
4). Notes recorded with VIEW are displayed.

Recorded notes can only be displayed in a list, and cannot be edited or deleted.
There is no function to output memo data.

The numbers are used for clues as to what time the memo is, but I think it can also be used for memos such as phone numbers.
