ER-A Model SRV (Service) Mode – Free Key Overview
FREE KEY Overview
SRV Mode Free Key programming, also known as 950 programming, allows you to easily place function
keys other than departments and PLUs onto a keyboard position based on your customer’s requirements.
Function Keys are keys that perform actions, such as cash, check, charge, void, RA/PO, and auto keys.
NOTE: For the ER-A320 and ER-A330,
950 programming is used to assign departments to the physical
keyboard. Optional key top kits may be purchase to access the newly assigned departments. PLUs can
not be placed directly on the keyboard. The PLU/SUB function key is used to register PLUs.
SRV Mode Key Number Assignment programming, also known as 951 programming allows you to assign a
key number to a fixed key position for departments, and direct PLU keys. Please see the chart below for
availability.
NOTE: Normally, there is no need to change the 951 programming from the MRS default settings which
are shown in the respective Sharp ER-A model Instruction Manual/Book.
Please see the respective Sharp ER-A model Programming Manuals and Dealer Knowledge Books for the
Function Key List and Key Position charts.
