Landing: AP & Power Levers alarm blocked

[Prosco]

Good morning all,

I am discovering the SAAB 340A and today my first tour of the track. Let me ask you three questions:

1 / when I remove the Auto-Pilot, how do I remove the alarm (video)?
2 / for the landing how to unlock Power Levers (video)?
3 / I don't understand the options of the preference window (video)?

Sorry for not knowing and thanks in advance for your help.

The video that shows my questions.

I think I have solved questions 2 / and 3 / but I don't understand what triggers the alarm that we hear in the video and especially how it is deactivated.

A little help, please would be appreciated. Thanks in advance.

To turn off the AP alarm, bring up the yokes and press the red button

I use keyboard shortcuts a lot. So hard to find.

Thank you very much.
