During their start phase, the TRACKERS display a 50 seconds countdown, as required by the UCI rules. Geographically located at the centre of the Velodrome, the "Official Starter" launches the countdown from the Main Judge Controller. To help the athletes to keep concentrated on the start signal, the TRACKER beeps at 30 seconds, 10 seconds, and then every second for the last five seconds, with a different sound for the last beep. The volume is adjustable, and the last sound (signalling the start) can be switched to a synthesized pistol sound. As soon as both STARTING GATES are open, the timing starts and the TRACKERS automatically switch to "Lap Counter" mode after 5 seconds. All distance values and the amount of laps are entered.
Both referees assigned as lap counters may independently decrease the laps by using a keypad located on the left side of the clock. The system is used by SWISS TIMING, and is homologated by the UCI for national and international competitions.
