How do I reset the GT (Grand Total) on this machine?
It may be the same as the 110DX, but I couldn't find the manual for the 210DX . This is from page 37 of the 110DX manual.
TO CLEAR THE GRAND TOTAL:
1. Set the Control Switch to the "PRG" (Program Mode) position.
2. Type , type , then press [R/A].
After this operation, the grand total resets to zero.
