To factory reset a Garmin TT15 collar, first make sure the collar is turned off. Plug the collar into its charger, then click the power button four times in a row. The indicator light will flash red and green, confirming the reset. This process restores the Garmin TT15 collar, including factory refurbished models, to default settings.
