The brownout detector doesn't work with DSMX. This was a point of criticism when DSMX was announced and there was a fair bit of discussion.

The reason is that DSMX is frequency hopping. The brownout detection system needs the transmitter to be on a fixed pair of frequencies. When the power is restored, if the receiver sees the same frequencies as before the brownout, it thinks the interruption must have been accidental. That's why it flashes when you fail to turn off the transmitter (which causes it to pick a new pair of frequencies. None of this works with DSMX.
