reseting date and exiting eddit mode

[toolmaker101]

Control # 8121 cnc engine lathe T-15

I was wondering how to edit the default date on the lathe.
I do not know how to do this I could use some help.

Also I pressed the edit button on the lathe and could not exit it, only turning off the machine did it.

Thank you in advance!
