DM Melody
built-in / Melody 1 / Melody 2 / None
Notification sound for incoming private messages. None disables the sound for this event.

Notification sound for incoming channel messages. None disables the sound for this event.
AD sound
built-in / Melody 1 / Melody 2 / None
Sound played whenever an advert is received from any node — pairs with Auto-Advert as an audible "in range" heartbeat (see Tools › Auto-Advert). None disables the sound for this event.
AD scope
All / Zero-hop
Filters the AD sound so it plays for every advert or only for local zero-hop adverts.
Melody 1 and Melody 2 are custom sequences editable in Tools › Ringtone Editor.

Radio

Options
Notes
TX Pwr
2–22 dBm
LEFT/RIGHT. With Auto pwr on this is the ceiling — the radio may transmit lower.
Preset
named presets
LEFT/RIGHT cycles community RF presets (region frequency + bandwidth/SF/CR). Enter opens a popup to pick one, save the current settings as a named preset, or delete a saved one. Applies frequency, bandwidth, SF and CR together.
Freq
chip range
Enter opens a digit-by-digit editor: LEFT/RIGHT moves between decimal places, UP/DOWN steps that digit. Bounds come from the radio chip's own validated range, so a value the radio would reject can't be entered.
SF
5–12
LEFT/RIGHT. Spreading factor.
BW
7.8–500 kHz
LEFT/RIGHT cycles the standard LoRa bandwidths.
CR
5–8
LEFT/RIGHT. Coding rate (4/5–4/8).
Pwr save
ON / OFF
Battery saver. Hardware duty-cycle receive (SX126x only): cycles RX↔sleep, wakes on preamble, cuts average RX current at the cost of some latency. Forced off (--) while the repeater is on — restored once it's switched off. A background watchdog auto-recovers if the sequencer gets stuck (soft re-arm, then a full reset) — see Tools › Diagnostics for the counts.
Auto pwr
ON / OFF
Adaptive Power Control. Lowers TX power on strong links, ramps back to the TX Pwr ceiling on weak/lost ones. Link quality from DM ACK SNR, or — for channels (no ACK) — a repeater's rebroadcast. Live power shown on the radio page/name bar. Default OFF. Suppressed (--) while the repeater is on — restored once it's switched off.
OLED
E-Ink
The repeater mode and its flood filters live on their own screen — see Tools › Repeater.

GPS pwr (if GPS detected)
OFF / 1 min / 5 min / 15 min / 30 min / 1 h
Battery saver. Cycles GPS off between fixes; each wake waits up to 60 s for a fix before sleeping again. Stays continuously on whenever something needs a live position — Trail recording, Live share, an armed Locator, Compass/Nearby, or an in-flight !gps fix. OFF (default) = always-on, as before. Status icon blinks while napping.
Units

Global unit system for every distance/speed shown in Tools (Nearby Nodes, Trail, navigate-to-point). Metric: m / km, km/h, min/km. Imperial: ft / mi, mph, min/mi

Keyboard

Notes
Layout
ABC / T9
On-screen keyboard style. ABC: a-b-c…z grid, one key per letter. T9: phone-keypad multi-tap — each key labelled digit+letters (e.g. 2abc); repeated Enter cycles the letters then the digit. Applies to whichever script page is active, not just Latin.
Main
Latin / Cyrillic / Greek
Which script the keyboard opens on by default. Latin is the default; picking Cyrillic or Greek makes that the one you land on, with Latin moving to the Additional cycle instead.
Additional
Latin / Cyrillic / Greek
The second script in the #@/abc key's cycle (Main → Additional → Symbols → Main). Setting it to the same script as Main drops the cycle to just that script plus Symbols. Greek covers the 24-letter alphabet plus final sigma (ς), not the tonos stress accents. Every script renders natively via one shared Unicode font — no separate toggle needed.
Applies to every on-screen text field (messages, waypoint labels, room passwords, preset names). Earlier releases labelled the grid QWERTY; the layout has always been alphabetical, so it is now named ABC.
European Latin-diacritic letters (Polish, Czech, Slovak, German, French, Spanish, Portuguese, Nordic, etc.) aren't separate alphabet pages — instead, Hold Enter on a plain Latin letter that has accented variants (a c d e i l n o r s t u y z) opens a one-row popup of its accents (e.g. holding a offers á à â ã ä å ą); LEFT/RIGHT picks, Enter inserts it, Cancel dismisses with no change. Holding a letter with no accented variants (e.g. b) does nothing. Works on whichever page is currently showing Latin, whether that's Main or Additional.
