DM Melody
built-in / Melody 1 / Melody 2 / None
Notification sound for incoming private messages. None disables the sound for this event.
Channel Melody
built-in / Melody 1 / Melody 2 / None
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
Setting
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.
Scope
text
Names your device's radio "community" (e.g. pl) — typing a name derives a shared key the same way on every device, so any device that types the same name lands on the same scope automatically, no key exchange needed. Tags this device's own DM/channel sends so repeaters can tell your community's flood traffic apart from others sharing the same frequency; paired with Tools › Repeater › Scope only, it's also what this device relays for in repeater mode. Not encryption — message content is unaffected either way. Enter opens the keyboard; empty clears it (unscoped, the previous default).
OLED
E-Ink
The repeater mode and its flood filters live on their own screen — see Tools › Repeater, including how it uses Scope above.

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
Metric / Imperial
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

Restarts this device. Pending setting changes are saved first. Last row, so it isn't the default-selected one
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.
Ext. KB
Full / Compact
Only shown on a build with CardKB support (CARDKB_I2C or ENV_PIN_SDA/ENV_PIN_SCL set). Picks how the on-screen keyboard behaves while a CardKB is doing the typing — see External Keyboard & Joystick.
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.
