ATS Mini V4 Button/Knob Quick Reference Card

Note: exact button/gesture mapping varies between stock firmware, the esp32-si4732/ats-mini community fork, and H.J. Berndt's firmware — always check Settings > About to confirm which firmware you're running, then reference that firmware's current manual for precise behavior.

Main encoder (rotate): tuning — frequency step size depends on current band/mode
Main encoder (short press): typically confirms a menu selection or toggles between tuning/menu context, depending on firmware
Main encoder (long press): power on stock firmware triggers deep sleep — on some community firmware builds this gesture is repurposed for a different function (check current docs before assuming this powers the device off)
Press-and-rotate (some firmware): larger tuning step, or scan-mode rescan trigger on newer community firmware builds

For the authoritative, currently-accurate control reference matching your exact installed firmware version, check the manual page linked from esp32-si4732.github.io/ats-mini (community fork) or the documentation bundled with H.J. Berndt's firmware release if that's what you're running.
