Memory

The current configuration, all presets, and all input audio levels are saved in non- volatile memory within 5 seconds of a change or exiting Audio Setup mode. When power is applied, the last current configuration is retrieved. The previous presets remain intact.

Wait at least 5 seconds after changing any configuration, saving a preset, or exiting Audio Setup mode. Before 5 seconds have elapsed, changes that you have made may not have been saved.
