There are a few instances in which you may want to perform a master reset on your Garmin GPS watch, including the following:
- Not receiving a satellite signal
- Restoring the factory default settings
- Not functioning properly
Performing a reset will erase some user data, including activity history, waypoints, courses, routes and tracks. Please see related content for information on how to back up user data and settings before proceeding. Learned fitness values for advanced fitness metrics including VO2 max, Training Effect and more will also be reset during this process. The watch will need to relearn this data after performing the reset.
To perform a master reset:
1. Turn off your Garmin watch**
2. Press and hold back/lap
3. Power on your Garmin watch while continuing to hold back/lap
4. Release Back/Lap button once
"Clear user data?" message appears
5. Select Yes
The reset is successful if your Garmin watch finishes powering up and goes to the setup wizard. Try the steps again if the setup wizard does not appear. Following the reset, place the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.
If the master reset does not work, another method to reset the watch can be tried:
1. Turn off your Garmin watch**
2. Press and hold the down, start, and back buttons
3. Power on your Garmin watch while holding these buttons
4. After the first beep release the start button
5. After the second beep release the remaining buttons
The watch should now be reset.**
If your Garmin watch will not power off, press and hold Light until the screen goes blank. This causes the device to power off and should only be used when a normal power down is not possible.
