Switch off (if hanged): hold LIGHT button for at least 25 seconds

CLEARING PROBLEMS WITH CORRUPTED DATA/GARMIN LOGO LOOP ETC:

Hard reset - method 1 - softer (clear user data): Switch off and wait for couple seconds. While holding BACK/LAP button press LIGHT button until Garmin logo appears, then let go LIGHT button still holding the BACK/LAP button until question about clearing user data appears. Answer yes.
WARNING: It clears SOME user made settings but for example leaves the IQ apps, backup data first!

Hard reset - method 2 (reset to factory settings) :
Power off the fenix 3 and wait for couple seconds
Press and release the Power button
Once the Garmin Logo appears Press and hold the Start and Back buttons.
When you hear the first beep (after ca. 60s) let the start button go
When you hear the second beep (couple seconds after first beep) let the back button go
The device will boot back up and you will be prompted to enter your profile information.

WARNING: It clears ALL user made settings,apps and current activities! So backup data first!
TIP: If you want to do a TOTAL hard reset when suspecting data corruption you can erase ALL data from the watch (GARMIN directory also), and even you can FORMAT it. After disconnecting the watch from you PC it will take relatively longer to restart but it will rebuild the data structure from backup (some user data will be also restored).
TIP: If you are left with only English language after hard reset or formatting the watch then, you have to download other language files through Webuupdater/Garmin Express
