Autopilot Question

I have an Autopilot LS1000. On the output knob there is a metal sticker with the line which indicates which number is selected. The sticker has come off. How do I know where the line should be on the knob? There are two little screw hole on the knob. Do either of these line up with the indicator?

Thanks in advance.

Dial it so that the set screws are in the 9 o'clock and 12 o'clock positions. The unit will then be set on 0 output. Use a Sharpie and make a mark on the 0 position.

Thank you!
