Night Dial Calibration

I set my blue bucket down with a clean click right beside the brushed aluminum volume knob. It glowed with a faint green backlight in the evening dim. Step one: check turning clearance. I braced my boots against the warm metal casing, placed both hands against the knurled edge, and leaned in with a steady push. The dial clicked smoothly one notch clockwise. Instantly, a tiny green indicator needle jumped on the small display panel. Surface cold, rotation silent, zero wobble detected. Evening audio check complete!
