You can save the [UTILITY] settings and [MY SETTINGS] as the [OWNER SETTING] for this unit.

For example, even after the settings have been changed by multiple users at an event, you can load the saved [OWNER SETTING] and the unit's settings will immediately revert to the saved settings.

For details, see [OWNER SETTING] in [UTILITY settings] in the Instruction Manual.
