4. When the countdown ends, the LED turns green, the display will show "-GO-" and the race will start.

Lap Timing

1. The timer will start recording lap times after the lap counter's sensor is triggered.

2. The lap count will increase with each completed lap triggered.

3. The personal best time format is in seconds and milliseconds (i.e.: 123.456).

4. Total race time will appear and can be scrolled through using the rotary encoder.

5. Total race time maximum display resolution is of: HH-MM-SS.xxMS . It will only display as large as the total time recorded, i.e.: 1-23.456 (for 1 min, 23 sec and 456 milliseconds).

6. The personal best can be shown and cycled though again when triggering lap counter's sensor, same applies to displaying the total race time (with the rotary encoder).
