Checking Eye Alignment
The bottom right corner of the Status display shows
the alignment status of the electric eyes. When the
eyes are aligned, the eye number is displayed ("#1").
If not aligned, or if the beam is broken, "x" is shown.
Important! When setting up the electric eyes, always take time to align the eyes as outlined above – even if the
timer indicates the eyes are aligned. This ensures a strong alignment instead of a possibly marginal alignment.
Timer Operation
1) Make sure the timer is stopped before the driver
starts his laps (press the START/STOP button to
stop the timer, if needed).
2) When the car breaks the beam at the start of the
first lap, the timer automatically begins timing
from zero.
3) As the car breaks the beam after each lap, the bot-
tom display shows the lap number, lap time, and
lap speed (if a track length has been entered).
Meanwhile, the main time display shows the run-
ning time of the new lap.
4) After the driver has completed all laps, press the
START/STOP button to stop timing of the current
driver. The timer is now ready for the next car.
Useful Features
Accidental Manual Stop
If the timer is inadvertently stopped by pressing the
START/STOP button, the lap can still be accurately
timed by pressing the RESTART button. This re-
sumes timing as if the timer had never been stopped.
As long as RESTART is pressed before the lap is
completed, the time is not lost.
Locking Out The Electric Eyes
If the beam will be broken during a lap by other vehi-
cles, the timer can be forced to temporarily ignore the
electric eyes. To disable the electric eyes, press the
Off
EYES OFF button. is flashed on the bottom
display while the eyes are off. To re-enable the elec-
tric eyes, press the EYES ON button.

By the way...
If the optional printer is connected, the lap time, lap
number and lap speed are printed after each lap.
If an optional scoreboard is connected, it shows the
running time as the lap is timed. When a lap is com-
pleted, the lap time remains on the display for about
five seconds, after which, it returns to showing the
running time of the new lap. (The amount of time the
previous lap remains displayed can be changed. Con-
tact FarmTek for assistance).
To avoid false triggers, the beam is ignored for about
two seconds after it is broken to allow dust and debris
to settle.
Note: If other cars or personnel on the track during
lap timing is typical, then the timer can be set to au-
tomatically turn the eyes off after any beam break.
This way, the eyes remain disabled the majority of
the time – the timer operator re-enables the eyes by
pressing the EYES ON button only when the desired
car comes near the beam. Contact FarmTek for more
information.
Previous Time Recall
Use the PREV and NEXT keys to scan back and
forth through previous times. The previous time dis-
play is removed after about ten seconds, or by press-
ing any other key. You may view a previous time
even while the timer is running.
