Occasionally, satellite data can become obsolete or corrupt preventing your Forerunner 610 from acquiring a satellite lock. Performing an AutoLocate on your device removes all of the current satellite data on the device and allows it to re-establish a proper connection with the satellites.

You may also need to perform an AutoLocate in the following circumstances:

  • The device has not been used in over two weeks
  • The device is powered on in a location that is 50 or more miles from where it is normally used
  • The distance or speed data appears to be inaccurate as a result of a corrupt satellite signal

To perform the AutoLocate:

  1. Turn device on, or take it out of power save mode
  2. Touch Setup
  3. Touch System
  4. Touch GPS
  5. Touch Satellites
  6. Press and hold Lap/Reset button
  7. Release button once satellite bars disappear

The Forerunner 610 will now be able to acquire accurate satellite data, providing you with a good satellite lock. After getting a satellite lock, the chance of inaccuracies in distance or speed will be greatly reduced. Keep in mind that GPS data may continue to improve throughout the duration of an activity.

NOTE: You may need to allow up to 15 minutes for best accuracy.
