Troubleshooting
Most problems show up in two places: the front light and the device screen. Start there.
What the lights mean
| Light | Meaning |
|---|---|
| Solid white | Booting up. |
| Pulsing white | Starting up or needs setup — check the screen. |
| Solid green | Connected to AirPlx and recording. (Brief blips = live audio / uploads.) |
| Pulsing red | Needs attention — the screen says what. |
A pulsing red light means one of: no network, no audio, a channel is down, or uploads are failing. The screen names which one.
Reading the screen
Tap the button to cycle through screens (Status → Network → Device). Common messages:
| Message | Meaning |
|---|---|
| Pairing Code | Ready to add to your account. |
| No Internet | Recording locally; check Ethernet / Wi-Fi. |
| Cloud Error | Online, but uploads are failing; still recording locally. |
| No Input (a channel) | Nothing is arriving on that channel — usually a cable. |
The Status screen also shows a level meter per channel: lit bars climb with real radio audio, an empty ladder means it’s quiet, and No Input means nothing is connected.
No audio on a channel
Work down this list:
- Check the cable. Make sure it’s fully seated at both ends. A loose or bad cable is the most common cause — the screen shows No Input and no level bars.
- Right input. Confirm the cable is in the CHANNEL you expect (1, 2, or 3).
- Source level. Turn up the radio’s record-out / line-out or volume so there’s actual audio to capture; watch the level meter respond.
- Mono source. The device captures mono — a stereo-only output may not work.
- Hum? Each channel includes a ground-loop isolator; if you hear hum, make sure it’s in line.
- Still off? An admin can open the channel’s Configure dialog (Managing devices) and raise Input gain or lower the Silence threshold if audio is too quiet.
No internet
You won’t lose recordings during a short outage. The device keeps recording locally and uploads everything once the connection returns.
Fixes:
- Ethernet: reseat the cable; confirm the port is live.
- Wi-Fi: check signal on the Network screen; if the network or password changed, re-run Wi-Fi setup (join AirPlx-Radio-XXXX, password airplxsetup, then pick your network). The device only supports a standard password (or an open network) — it can’t get past a captive-portal sign-in page. If your Wi-Fi needs one, use Ethernet instead.
Local storage isn’t infinite — during a very long outage (roughly two weeks, or once local storage fills) the oldest audio is dropped. Reconnect sooner than that to keep everything.
Pairing won’t complete
- Code expired? Pairing codes last about 15 minutes and the device makes a fresh one automatically — just use the newest code on the screen.
- Just powered on with no internet? The device needs the correct time to pair. Give it a minute on the network (Ethernet or Wi-Fi) and try again.
- No internet yet? Get it online first (Ethernet or Wi-Fi), then pair.
Restart or reset the device
The single button drives both, with a countdown on the screen:
| Action | What it does |
|---|---|
| Tap | Change the screen. |
| Hold 3 sec | Reboot. |
| Hold 10 sec | Factory reset. |
Let go early to cancel. A factory reset erases the device’s pairing, saved Wi-Fi, and any audio still waiting to upload, and returns it to first-time setup (the AirPlx-Radio-XXXX hotspot reappears). Use it when you want to move a device to a different account or start clean — then pair it again.
Re-pairing a device
After an unpair or a factory reset, set the device up again:
- Get it online (Ethernet, or Wi-Fi via the AirPlx-Radio-XXXX hotspot).
- In the AirPlx web app, go to Settings → Radio → Add Device.
- Enter the new 6-character code from the screen and Claim.
Find your serial number
Your serial looks like R-XXXXX (for example R-7K9Q2). Tap the button until you
reach the Device screen to see it, along with the firmware version.
