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: the SX126x cycles RX↔sleep on its own and wakes on a preamble, cutting average RX current. Trades a little receive latency; leave OFF for lowest-latency reception. Requires an SX126x radio (otherwise stays on continuous RX). Forced off (shown as --) while the repeater is on — a repeater must listen continuously; your setting is restored when the repeater is switched off.
Auto pwr
ON / OFF
Adaptive Power Control. Lowers actual TX power on strong links to save energy, ramping back up — to the TX Pwr ceiling — on weak or lost links. Link quality comes from direct-message ACK SNR and, for channel messages (no ACK), from hearing a repeater rebroadcast your packet. The radio page / name bar shows the live power. Default OFF (fixed TX power). Suppressed (shown as --) while the repeater is on — a repeater holds full TX power for consistent relay reach; your setting is restored when the repeater is switched off.
