There are a few parameters that affect slaving, and also how the unit reacts
when the input is removed, which can be accessed by pressing Configure.
This gives two pages of settings – the first page covers behaviour when sync is

"Revert to Master Mode" – when the input goes away, the unit reverts to the 992

"Revert to Learned Mode" – when the input goes away, the unit reverts to its
stored learned frequency.
