There are a few instances in which you may want to perform a master reset on your Foretrex 301 or 401, such as:

  • not receiving a satellite signal
  • want to restore the factory default settings
  • not functioning properly

All settings, user data*, and satellite data may be erased when resetting the GPS. User data can be backed up to the computer, therefore refer to the FAQ article "How do I back up user data from my outdoor GPS with a USB interface?" before performing the reset.

To perform the master reset:

  1. Turn off the device
  2. Press the ENTER and POWER buttons simultaneously
  3. Release on the buttons when the Erase All User Data? message appears
  4. Select Yes

The device will now reboot and is reset. You will want to leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.

*User data consists of waypoints, routes, tracks, and geocaches
