Before each race, ensure that the printers and timer are connected. Make sure both
printers are on and on-line. Check to be sure both printers are enabled. If “off” shows up
by either Log or Time Slip, refer to System Configuration Settings in Section 3.3 on
enabling them. If “not ready” shows up by Log or Time Slip, something is not working
right from the computer to the printer.

the scoreboards. Refer to Scoreboard Diagnostics in Section 3.3 for
instructions on the use of the scoreboard diagnostics function.

Final Testing

Finally, drive a car down the track at constant speed and check the operation of the entire
