Well, the firmware update did nothing to help solve the PM5 problems.  But it sure did change the symptoms.  Now, while I am rowing, at random points, the PM5 will throw an error, but it will keep working and talking to painsled.  I can push continue, and everything will be fine for a while, and then it will repeat.  The time between errors can be just a couple of strokes, or as long as 10 minutes.

I checked the batteries, and they claim to be at 96%, which makes sense since I replaced them last week when this problem started.

I guess it  is time to contact Concept2.  For now, I think I will swap out the monitor to a PM3 that I have lying around.  I’ll see if that works better with a USB cable than the PM5 works via BT.

The session was uneventful.  I really like the 4×12′ session.  It’s a quick session and the 1:59 pace put me right on the edge of my aerobic HR zone, and a bit over at the end.

On the chart, you can see when I got the screens because it caused the blips in the pace.  By my count I had 18 interruptions due to error screens
