P-Mode Programming

Default Program

The ER-390M arrives with a default or generic program already installed. Program options are set to 0
(Zero), unless otherwise noted, which means the machine can be operated immediately after a RAM
clear procedure is performed.
For example:
ER 390M Electronic Cash Register v1.2
All keyboard PLUs are preset at "0" with preset override allowed, default option status
programming of "0000000".
All system options are set to 0 in default programming, unless otherwise noted. Change
only the options that will deviate from default programming. There is no need to re-enter
an option status of 0, since 0 is its original setting.
All programming (unless otherwise noted) is done with the control lock in the P position.
Each section details a specific area of register programming.
