i. e. rEvo assumes that if the PO2 is under .5 for 5 minutes, it shuts down.
That's a feature that can be turned off if you want. But you will have to shut down the rEvodream after your dive.

But, the HUD is being driven by the same circuitry, therefore no isolation between cells. If the controller goes awry, you loose all.
If the controller goes away, you still have a valid PpO2 reading on the display.
