If you can't get communication or GPS on a TT15 Garmin collar, first ensure that the collar is fully charged and turned on. Next, check for any obstructions or interference that could be affecting the signal, such as dense terrain or electronic devices. If the problem persists, try updating the software on both the collar and the handheld device to the latest version, and perform a factory reset if necessary.
