ER-A Model SRV (Service) Mode – File Allocation Overview
Increasing and Reducing the No. of Records
It is always safe to increase the size of a particular File Group if memory is available to accommodate the
increase.
When reducing the size of a particular File Group, do not reduce the No. of Records below the
No. of Used
Records to prevent data loss.
E.g. Using the Example ER-A520/530 970 File Reading below:
In this example using the MRS defaults, PLU/UPC Group No. 4 must not be reduced below 20. If reduced
below 20, any data associated with those records is lost.

File Table No.
(Depends on Model*)
Description No. of Records No. of Used Records
4 PLU/UPC 2000 20
* ER-A520/520 970 Reading Prints according to Group No.
NOTE: Reducing the number of Records can free up available memory space.
EXAMPLE:
At MRS, the ECR has 2000 records reserved for PLU/UPC (sales items). You determine that they will not
require or use more than 500 records. You can safely reduce the No. of Records for the PLU/UPC File
Group to 500 to free up available memory for use by other File Groups without losing data in records 1-
500.
