Hello, new FR 55 user here. So far I love the watch, but I cannot seem to set it to turn on the backlight while 'gesturing', neither during an activity nor not during one . I tried resetting to default settings but no luck, is there some setting that I have to look at in order for this to work (I read something about a metronome in other post but for a different model)?. Any help will be appreciated, thanks a lot.
