68jk09, nfd2004 is correct. I recently purchased a SCAN DISK from CVS....You can also purchase it from Radio Shack or any electronic store...There are different sizes regarding how much information that can be saved on the disk. Before I did all the alarm assignments for 319, 274 & 129 , I made the purchase. Every night after I typed a page or two, I would plug the SCAN DISK into the side of my labtop and saved what I had done.
It is worth the $ 15.00 or more, again depending on what size of storage you want.
