I don't have a manual for the UX-41 but here's the procedure for a UX-40. Hope it works ...
1)Turn the keyswitch to the 'X' position
2)Enter a '1', press the decimal key
The till will display the currently set date.
3) Enter the new date as YYYYMMDD - must be 8 digits.
4) Press the 'X' key.
Good luck ...
