Hi.
If it has the standard departments on the keyboard,
Turn key to P mode.
Type: 1, then the department number to be changed using four digits, so if you were changing dept 1, type 10001. For dept 25, type: 10025
Now press PAID OUT button
Now type the new name using your programming character sheet. This is usually kept under the other keysheet on the keyboard.
Now press CASH/TEND.
That should do it.
