Time race
During the race the remaining time will be displayed (fig.  3) until 
00:00:00 is reached. The lap counter will then no longer respond if 
a vehicle drives through the light barrier. An acoustic signal can be 
heard every time a vehicle passes through the light barrier during 
a race and the number of laps displayed for this lane will increase 
by one. 
The race is at an end when the time counter reaches 00:00:00  
(fig.  4). The maximum number of laps which can be displayed is 
999. If this number is reached in the course of a race, the counter 
will reset to zero and counting will begin anew. 
Cancelling a race or a further race
Press the  C or  E button for longer than 2 seconds. The standard 
flashing display will then  appear and the racing  can be selected 
again.
Automatic switch-off
If no car passes through the lap counter or no key is pressed for a 
period of 3 minutes, the lap counter will switch off automatically in 
order to save power. You can return to the Enter mode by pressing 
the ON/OFF switch.
Troubleshooting 
Driving tips
• By pressing the buttons  C and  E for a short period of time you 
can select either a lap or a time race.
• Neither transmitter nor receiver may be obstructed by sections of 
track or any other objects. An obstruction of the light barrier would 
cause a malfunction of the lap counter. 
• The lap counter may only be set up over sections of track which 
are lying flat.
• In the  event of  any malfunctions, all  four batteries must be re-
placed.
