AN UPDATE TO THE ROM FOR CHANGING DIAG
SPECIFICATIONS AND CALCULATING METHODS FOR
PLU FOOD COST.
1.Model Name:
ER-A750
2.General:
2-1) We have updated the part for DIAG’s product inspection.
2-2) An SSP will be distributed for the following 4 changes in function.
2-3) An upgraded version of the production ROM will be distributed from September 97.
This new version will contain the information mentioned above as well as
information from Technical Bulletin A750-004.
3.Description:
3-1) An update to the part for DIAG’s product inspection.
1) Modifications have been made to improve the efficiency of products and test
diagnostics.
2) IrDA, ASK & SRN Check (CHECKER MODE) have been added to the IrDA
Diagnostics SUB MENU. Because of this, the contents displayed in the sub
menu have changed. However, it is a menu to be used for product inspection,
and operation procedures for the service dialog are the same as before.
3-2) An SSP will be distributed for the following 4 changes in function.
1) In the past when PLU food cost percentages were calculated, VAT and service
charges (service charge included in SBTL: only when SRV904C = + 4) were
not subtracted from the sales amount. 
Food cost percentages can now be calculated with the formula below.
Food cost % = (sales value Q’TY 
×
 food cost) / (gross sales – VAT – service 
charge)
(Concerning service charge calculations, include service charge amounts in 
SBTL: only when SRV904C = + 4)

receipts using Intermediate GLU Reading, a Paper Empty error will occur 
during printing.

Even if the above setting is performed, items set to “Do not print on receipt” 
can now be printed with Intermediate GLU Reading.
4) When performing the setting below, if a chit receipt is printed with the
