M e m o r y C h e c k
Backup memory CMOS existing only in model JAN CD-
board and ROM/RAM memory on all CPU
boards are self-diagnosed.
Self-diagnosis includes items checked at system
startup and after startup.

CMOS Check
T o t a l C h e c k
Total check is made after system startup and CMOS
error is detected by total check sum on CMOS
memory.
This check is performed or not depending on the
system number.

When an error occurs in CMOS, the following alarms
are generated:
I
ALM109O: Setting total check error
ALM1091: Parameter total check error
ALM1092: Keep memory total check error
ALM1093: Offset total check error
ALM1094: Macro program variable total check
error
ALM1095: Processing program total check error
If an alarm occurs for some reason, CMOS data may
be destroyed. The alarm can be erased by tempo-
rarily writing the data from the CRT control panel,
then depressing the ESE
key on the control panel.
No alarm can be erased for processing programs.
