Make it safe first
Land, disarm, disconnect power and remove propellers before bench testing. A warning is information, not a challenge to bypass.
Pause and verify this point against your aircraft manual, current conditions and the official rules where you will actually fly.

Pause and verify this point against your aircraft manual, current conditions and the official rules where you will actually fly.

Pause and verify this point against your aircraft manual, current conditions and the official rules where you will actually fly.
