OPERATION OF THE TIMESTOPPER MODEL T-III

1. Assure that the finish sensors are installed in the track correctly (see the section on INSPECTION AND INSTALLATION OF T-III FINISH SENSORS).



2. At the finish line, assure that the incandescent illumination set up over the finish line is turned on, undisturbed, and remains in the same location from race to race.   Make sure that all cars are removed from the finish line, and make sure that no one inadvertently will move their hand or other obstacle over the light sensing holes at the finish line before the finish of a race.   Check beforehand that the sensor holes in the track are free of light-obstructing debris.



3. Place your racecars with wheels staddling the track's guide rails and with gravity pulling them against the posts of the track's starting gate, ready for the start of a race.



4. Turn the Timestopper ON/OFF switch from OFF to ON.   This resets the display so no display lights are illuminated.   Lower the starting bar of the track.



5. After your cars cross the finish line, the Timestopper display will show the results.   A green light illuminated in the display for a given lane indicates the car in that lane finished first.   A yellow light indicates a second place finisher.   An absence of illumination of either color indicates third place.



6. To start a new race, first record the result of the previous race.   Then position the racecars at the start gate position.   Next, turn the unit OFF and back ON again.   Finally, release the start gate to begin the race.
