[visionrehabtherapist] PenFriend remaining memory

Hello everyone,Does anyone know of a way to tell how much memory is remaining 
on your PenFriend once you start to use it? I know that it starts out with 70 
hours of memory but is there a way to tell how much you've used up and how much 
you've got left?

Thank you in advance!
