Everything that tailors AVR Maestro to you and your gear - manage receivers, theme the whole app with TJ Mode, tune the volume step, grab a debug log for support, and back up your entire setup to a file.

| Section | What's in it |
|---|---|
| Devices | Switch receivers, full Device Information, Manage Receivers (rename/delete), Add Receiver. |
| Receiver | Remote Lock - lock or unlock the receiver's own physical IR remote from the app. Only shown on receivers that support it. |
| Appearance | Theme (Light / Dark / Device / AMOLED true-black) and TJ Mode - pick any accent color and the app rebuilds its palette. Plus Display Size, Widget Size, Customize Navigation and Customize Tabs. |
| Audio | Volume Step (0.5-2.0 dB), whether the absolute volume or dB shows on top, and Gradual vs Direct volume presets - Gradual (the default) ramps smoothly to a preset's target instead of jumping straight there, on the main zone and Zone 2/3. |
| Help | Explanation cards toggle, restore dismissed cards, and a live Debug Log with one-tap Save & Share for support. |
| Developer Tools | Hidden until you tap the version number (in About) seven times - then it stays available across launches until you remove it. Raw Telnet / HEOS commands, AJAX dump, and a volume-cap wire diagnostic. |
| Backup | Export every receiver, preset and preference to a .zip file that also bundles your custom input icons, and import to restore on a new phone - works on both iOS and Android. Older .json backups still import fine. The file holds no credentials, only receiver IPs and your own preset names, so it is safe to share. |
