Garmin Forerunner guide index

Check the manufacturer’s reference first

Forerunner is a family of watches, not one model. The linked Garmin manual is specifically for the Forerunner 245/245 Music. Use the documentation for your own watch; an older F-number label in this index is not proof that Garmin defines the same diagnostic code on every Forerunner.
