I've updated the software (5.10) through Garmin Express, synched the watch with my phone and with my computer, done a hard re-start, enabled the vibration settings (the watch vibrates with notification and key press), tried deleting alarms and resetting them. and the alarm settings are set to vibrate. All that happens is a high pitch noise. :( Just opened the box this afternoon - super disappointed. What am I missing? My Forerunner 35 was no hassle right out of the box.
