When you are making changes to settings within a sub-menu, the system will not save your adjustments if the MENU switch is held down for more than 1 second. Your changes will also be lost if the setting process is aborted before completion, returning the display to the normal screen without applying your selections.
Click steps to track your progress.
Ensure you complete all desired adjustments within the sub-menu before attempting to exit.
After making an adjustment, use the 'Select' (F4) or 'Set' (F4) switch to confirm and save your changes.
Avoid pressing the 'MENU' switch for more than 1 second while you are actively in the process of changing a setting.
