Which control is used to manually set N1 reference bugs and readouts?

• A. By turning the N1 SET outer knob
• B. By pressing the N1 button
• C. By turning the N1 SET inner knob when the outer knob is positioned to BOTH, 1, or 2
• D. By selecting the N2 knob

Answer: (C)

Manually setting N1 reference bugs and readouts is done with the N1 SET control, but only when the outer selector is in a manual mode. The outer knob chooses the mode or source for N1 (such as BOTH, 1, or 2), while the inner knob is the actual adjustment control. Turning the inner N1 SET knob in those manual positions changes the N1 reference value, and the bug marker and readout update to reflect that new value. If the outer knob isn’t in one of the manual positions, the inner knob won’t affect the N1 readout, so the adjustment won’t take effect. The other actions described don’t modify N1 references—pressing a button typically toggles or acknowledges displays, and using the N2 knob targets N2, not N1.
