User's Manual
Probable cause and possible countermeasure
• Check the setting of [SYS2]-[OUTPUT]-[ONSTATUS].
To lit the indicator (OUTPUT signal ON) when the judgment is OK,
select [OK ON], and to lit the indicator (OUTPUT signal ON) when
the judgment is NG, select [NG ON].
• Is the operating mode switch set to "RUN"?
• Is the "Eco" mode function set?
The "Eco" mode is set if pressing any key automatically returns to
the original brightness.
The brightness is maintained when the "Eco" mode setting is can-
celed. Note, however, that the life of the LCD backlight is short-
ened. So, we recommend setting the "Eco" mode.
