Advanced Operations and Setups
This chapter describes more sophisticated operations that you can use to suit the needs of your retail
environment.
Clerk interrupt function
There are two types of clerk interrupt function, illustrated by PROCEDURE 1 and PROCEDURE 2 below.
• In PROCEDURE 1, each clerk possesses a unique clerk interrupt buffer, and so the clerk interrupt function
gives each individual clerk the ability to perform an independent registration operation. In this case, each clerk
is individually linked to a unique clerk interrupt buffer.
• In PROCEDURE 2, multiple clerks use the same clerk interrupt buffer, and so a single clerk interrupt
operation (clerk change during registration) can be performed any registration is in progress.
In this case, multiple clerks are linked to a single clerk interrupt buffer.
Note the following important points concerning the clerk interrupt function.
1. The register must be programmed to allow the clerk interrupt function.
2. To use the clerk interrupt function, a clerk interrupt buffer must be allocated with the memory allocation
operation. Next the manager control operation (X1 mode) should be used to perform clerk assignment for the
clerk interrupt function. The clerk interrupt operation cannot be performed by clerks who are not linked to a
clerk interrupt buffer.
In the REG1, REG2, and RF modes, clerks can be changed while a transaction is in progress, making it
possible for multiple clerks to simultaneously perform registrations in the same mode using a single register.
For example, if clerk 1 is interrupted while registering a transaction, clerk 2 can use the same machine to
register a different transaction. Then clerk 1 can continue the original registration from the point where it was
interrupted.

NOTES
• A guest receipt can be issued following clerk change, and receipts can be issued separately for each clerk.
• A cancel operation can be performed during registration by either of the clerks. When clerk 1 signs back on
(after being interrupted by clerk 2), the cancel operation cancels only the items registered after signing back on
(only this receipt) or from the top of the transaction. This is selectable by the key program.
