Hi. these are too old to have a manual online. I know a bit about them though.
End of day should be standard Sharp:
Turn key to Z mode.
Press the decimal point button.
Press TL (CASH) button.
If there's anything else you need to know, just ask.
Also, make sure the internal battery has been replaced within the last few years. This model had bad problems with the battery leaking when old, and damaging the machine.
