PBE-M5-300 "Untested Hardware"

I have just acquired a PBE-M5-300 and flashed it with the nightly build.  It has an "Untested Hardware" banner on it.  From other posts here, I gather that means there may be something different about my hardware than you have run into before.  Below is what the /sysinfo.json page shows.  As you can see, the board ID is0xe3e5.

Please advise what if anything further I should do.  I just got this, and so far all I know is that this node will communicate with a NSM5 in an adjacent room of my house!  But we are counting on it for an upcoming ARES event with a 10 mile hop, so hopefully there won't be any show stoppers.
