Why did the pilot in this EC135 crash change the throttle setting after encountering wake turbulence? I’m confused in this accident why the Eurocopter EC135 pilot decided to manipulate the throttle after encountering wake turbulence - I can’t think of a reason for this. Could someone please explain why a pilot would do that?
It's the second sentence on the first page of the report:

He inadvertently rolled the throttles to manual, and never restabilized the
engines or main rotor rpm.

Supplemented by (the next sentence):

In addition, he did not understand the reset procedures for the
engine controls (FADEC), and never returned the engines to FADEC control.
