Normal: The light switches on when you press START/DATA for more than 2 sec, when an alarm is activated or when you reach a waypoint. The light stays on as long as a selection is active and for 5 seconds after the last press of a button.
Night: The light switches on when you press any button and stays on for 5 seconds after the last press of a button.
I generally use just the normal setting. |
