There are a few instances in which it may be necessary to perform a master reset on the Edge 800. A master reset should be performed if the Edge is:
- Not functioning properly
- Needing to be restored to factory default settings*
- Not receiving a satellite signal
- To bring up language selection prompt if incorrect language text is showing
- Unable to pair up accessories, such as the heart rate monitor or speed/cadence sensor
All settings, workouts, and satellite data will be erased when resetting the GPS. Workouts can be backed up in Garmin Connect. Refer to the FAQ article "How can I backup my personal settings and profiles on my Edge 800?" to back up personalized settings.
To perform the master reset:
- Power device off
- Press and hold Lap/Reset and Start/Stop
- Power device on while still holding both buttons
- Continue holding buttons when the Garmin "splash" screen appears
- Release buttons when Garmin "splash" screen disappears
The Edge 800 is now reset. Leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.
*A User Data Clear can be performed in order to remove personal settings without removing history.
To perform the User Data Clear:
- Power device off
- Touch and hold finger in top-left corner of display
- Power device on while still maintaining pressure on display
- Release display when the Reset device settings to factory default? message appears
- Touch Yes
This will erase personal settings, such as the user profile. However, saved activities will not be removed.
