## What is シンプルストップウォッチ?

Press the Start button to start the stopwatch. By changing the setting, the LED light next to the camera can be turned on at the same time as the start button, or the whistle sound can be output at the same time as the start button. With a simple design stopwatch that also has the basic functions of a stopwatch, you can notify the exact start of the stopwatch even to a distant opponent.
