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.
