Using the Garmin Forerunner 965 is easy. First, turn it on and pair it with your smartphone if you want extra features. You can set up your customizable training plans right on the watch or through the app. When you go for a run, hike, or any outdoor activity, just start the relevant tracking mode, and the built - in GPS will record your route. For health tracking, it works automatically throughout the day. As for maintenance, keep the watch clean by wiping it with a soft, dry cloth. Avoid exposing it to extreme temperatures or harsh chemicals. If you have any issues, check the user manual or contact Garmin's customer service.
