Explanation of Display:
Run Timer
The run timer counts the normal operation hours, not the standby hours. The actual value of the run timer
is displayed in SDM and CSM. The run timer displays hours in hexadecimal format. This display will
increment based on the amount of time the set has been on. The timer will also be incremented one hour
each time the set is turned on.
Software Identification, Cluster, and Version
The software identification, cluster, and version will be shown in the service main menu display.
These numbers consist of the last part of the customer identification printed on the IC package; the
screen will show "AAABBC-X.Y". (Example: L90US1 1.2)
− AAA is the engineering project name (Ex: L90 = L9.0).
− BB is a function specification indicating specific functionality or a region (Ex: US). Processors with the
same engineering project name and function name are interchangeable, except for the languages
they support.
− C is the language cluster number within the "BB" software version (Ex: 1 = English/Spanish/French)
− X is the main version number (Ex: 1)
