the memory on my Pronto was at 44% when I got it this conserned me. But I read in the manual that the remote stores all deleted devices untill the memory gets tight then it defrags and deletes the un used info. It looks grim but If it get tight it should free some up. I've only used 15% and replaced every button on five remotes.
QUESTION:
Where is the serial number on or in the unit to match the one on the box??? You know for warranty
identification.

Thanxs to Jack for your help!!!!
