The modified constants mode is used to change or display user constants that have been changed from their
factory-preset values.
When any user constants have been changed in programming mode (b1-01 through o2-08), press the DATA/
ENTER Key in modified constants mode to display these user constants. (The initialize mode user constants
won’t be displayed.)

have been changed from their factory settings.
The settings for these two user constants are displayed, and the setting for d1-01 is changed from 60.00 Hz
to 30.00 Hz while C1-01 is set to 20.0 seconds.
