Just some minor corrections on Darren's otherwise great instructions:
> If the timer is beeping continuously, one or both of the sensors is not in

> alignment by checking the lights on the boxes. Have someone walk through
> the start then the finish to verify you get a time.

> You will hear a single beep whenever somebody trips either the start or
> finish light. That is OK.
On the top edge of the LCD display, there is a little indicator that
appears whenever the start or finish is being tripped. You can figure
out which light is misaligned by looking for which one is on constantly.
Also, you actually hear different beeps for start and finish trips.
Start is a single "beep", finish is a quick double "beep-beep".
> There are 4 displays, and 4 possible cars can be on course at any given time:
Actually, although there are only 4 displays (and Darren correctly
identified their purpose), the clocks can handle up to **8** cars on
course at a time. Their clocks aren't all displayed, but it will work
fine.
