- Make sure auto-pause (bike settings) and auto-power-down (system settings) are both set. This is the default.
- Start riding towards ride meeting place.
- Hit "start/stop" to start recording data.
- Reach your meeting point. Wait. Chat. First the system "auto-pauses", then finally the system auto-power-downs, but you don't notice because you're chatting.
- Start riding again.
- Notice system is off, so you turn it back on, figuring everything should be okay now.
- Begin your critical climbing interval (which for purposes of this work we'll refer to as "OLH"), you hit "lap". The system reports a lap time and everything seems fine.
- Finish your critical climbing interval, you hit "lap". However, no lap data have been saved. Indeed no data at all are being saved....
It's a bit of a shock to get to the end of your ride only to find that you have data only up to your meeting place. That critical climbing interval, an important fitness test, one where you want to carefully analyze your pacing, is lost in the neverland of lost numbers. It's gone. Simply gone.
The solution? Shut off auto-power-down and/or shut off auto-pause. Auto-pause is what put the system into non-recording mode, and when it's in non-recording mode it auto-powers-down, and once it auto-powers-down it forgets that it had been recording.
I may be a nimrod at times, but the fact is I've never lost ride data in this way with the Saris Cervo "Little Yellow Computer". What would typically happen with that was if I would stop, it would shut off after 4 minutes, then after I started riding again I would take awhile before I realized I needed to turn it back on therefore I'd lose these segments of data. But if it was on, it was recording.
So my solution for the Edge 500 is to shut off auto-power-down. I'll just need to remember to shut it off when I'm done with my ride and I'm not going to plug it into a USB port from which it can draw current. Hopefully I avoid losing any more data in the future.
