Casio V-N500 - Manual (Page 68)

E-66
Resetting the Paper Writer is the same as resetting a PC. Performing a reset causes all
unsaved RAM data to be lost that are in mid-course of inputting and editing, but data
and settings that are already stored in the FlashROM should be unaffected.
Perform a reset to restore normal operation whenever the Paper Writer operates
abnormally due to misoperation or some other reason.
Use a pointed implement such as a mechanical pencil (with the lead retracted) to
press the reset switch on the back of the V-N500.
This starts the reset operation.
Do not use a toothpick or pencil or other sharp object whose tip may break off the
reset switch. *
