Setting changes not reflected — Your adjustments were not saved

What does ConfigNotSaved mean?

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.

Common Causes

  • Pressing and holding the 'MENU' switch for more than 1 second during a setting modification.
  • Exiting or aborting the setting change process before all steps are completed and confirmed.

Repair Steps & Checklist
