Using the Forerunner 165 is a breeze. First, turn it on and pair it with your phone via Bluetooth to get the most out of the features. You can then start setting up your personalized adaptive training plan. Just tell the watch your running goals, like distance or time, and it will create a plan for you. When you go for a run, simply press the start button to begin tracking your progress. The bright display will show you all the important information, like your speed, distance, and time. As for maintenance, keep it clean by wiping it with a soft, dry cloth. Avoid exposing it to extreme temperatures or getting it wet for long periods. If you're in the rain, dry it off as soon as you can. And remember to charge it regularly to keep it running smoothly.
