From the Forerunner 235 Owner's Manual:
Wrist Turn: Allows your device to turn on the backlight automatically when you rotate your wrist toward your body.
While this would be invaluable during a run, I'm having a hard time making the feature work. Is there a magical hand motion one must master to get the backlight to turn on automatically? During a night run, I got this to work 2 out of 10 times. And when it worked, there was a lag, that I tend to reach out with my right hand to turn on the backlight manually.
Any tips, suggestions or videos would be greatly appreciated.
Kind regards,
