What they mean:
L01: Monitors the Crossfire frequency mode, activated when it's not in 150Hz mode
L02: Activ when the Link quality drops below 80% (pre warning) AND 50 or 4 Hz mode is active
L03: Same as L02 but with the critical warning level at 70%
L02 and L03 also got a small delay (0.5s) to avoid warnings when the signal is only bad for a short moment.
Note: since Crossfire fw 2.93, the RFMD no longer needs to be compared as the LQ sensor will stay
at 100% while in 150Hz mode (RFMD = 2)
With the logical switches the voice alerts will be triggered every time they are active.
What they mean:
SF1: when L02 is activ, plays the selected track ones -but not at the startup
SF2: same as SF1 for the critical warning
For the sounds you can create your own with a free TTS creator on the internet.
Model match in OpenTX (and FreedomTx on Tango 2)
Model match enables you to make sure that a specific receiver and drone with it only binds if the correct
radio model is selected. In case you switched from a drone to a wing and forgot to change the model, the
Rx will simply not bind (unless you start the bind procedure).
You need to make sure that you don’t use an id twice in different models. In this case, the Rx will bind to
both of them!
