Using your Active Pro 1702 Digital Sports Watch is a breeze. To set the time and date, look for the buttons on the side of the watch. Press the appropriate buttons to enter the setting mode and use them to adjust the values. You can easily switch between 12 - hour and 24 - hour formats in the settings. The chronograph function is great for timing events. Just press the start/stop button to begin and end the timing, and the reset button to clear the time. When it comes to the alarm and chime, you can enable or disable them according to your needs. For maintenance, keep your watch clean by wiping it with a soft, dry cloth regularly. Avoid exposing it to extreme temperatures or water for long periods, as this may damage the internal components. With proper care, your watch will serve you well for a long time.
