Garmin Express (Version 6.19.2.0) sais that I have the latest software version on the device.
I encounter twice this problem:
I connect via Garmin Edge 520 to indoor power trainer (Elite Direto X) to start the activity. I set the target power to 150W and start the "Train" activity. (back button to main menu screen -> down button -> Training -> Indoor Trainer -> Set Target Power -> x [W])
After 5 minutes I change the target power to 200W and play the "Train" activity control the trainer power output.
I continue this for aprox 50 minutes, then I do the same things to switch back to 150W.
After aprox 5 minutes (after aprox 1:00:05 time of activity) I press the stop button (pause/stop/start button) and the Devices turns off completly.
When I power up the Device in order to complete the activity, the activity timer is at aprox 59:00:00.
Why the device turns off? I do something wrong?
Thank you!
