Using this Dunlop sports watch is a breeze. To check the time, simply glance at the dual digital and analogue display. If you want to set the daily alarm, use the mode switch to access the alarm setting and set your desired time. You can use the 4 - minute snooze option if you need a little extra rest. For timing events, use the chronograph or stopwatch functions. Remember, this watch is water - resistant up to 50 meters, but don't expose it to hot water or high - pressure water jets. When the display gets dim, open the back cover carefully and replace the CR2016 Lithium battery. Keep it in a dry place when not in use to maintain its performance.
