Step 6. Reinstall encoder knobs:
1. Place encoder knobs over encoder shafts.
2. Leave approximately 0.06” (1.5mm) gap between back of encoder knob and face of
bezel.
3. Tighten encoder knob collets using flat blade screw driver. Verify knob operation by
rotating knob and pushing in knob. Detent in knob push should be detectable and knob
should not contact bezel. When depressed, verify gap dimension by slipping a piece of
paper between the knob and the bezel (paper is approximately 0.005” [0.1mm]). The
paper should fit easily.
4. Reinstall encoder knob caps into encoder knobs. Ensure proper location of heading and
course caps.
