Settings to Initialize User Constants

Initializing to User Settings

This function initializes the user constants to values that have been recorded as user settings.
To record the user settings, change the user constants to the desired values and then set user constant o2-03
(User constant initial value) to 1. Once user settings are recorded, the o2-03 value will be automatically
reset to 0. (The 1110 function will be disabled when user constant o2-03 is set to 0.)

Use constant A1-03 to initialize the user constants.
When initialized, the user constants will return to their factory-preset values. You should normally re-
cord the setting of any constants that are changed from the factory presets.
