Adjusting the Ball Detectors
The ball detectors within the Duo Camera Module are designed to validate the score so that a
score is reported to the monitors only when a ball is actually bowled. Therefore, if a pinsetter is cycled
from the cycle button at the ball return without bowling, no false scores will be displayed.
In order to function, the ball detectors must first be adjusted so that the beam of light from the
detector hits the reflector mounted on the thin capping and bounces back to the detector.
 When the unit is properly adjusted, then LED indicator on the end of the detector will be off.
Whenever a ball goes past, the LED indicator will flash on and then off again.
 If the detector is not adjusted properly, then the LED indicator will remain on. This will result
in no scoring being displayed at all.
 If the detector is adjusted poorly, you may notice that the response of the LED is sluggish,
so that the LED goes off only sometime after the ball has gone past.
To adjust the ball detectors, loosen off the four screws at the top of the eyeball bracket and
rotate the ball detector up and down, side to side until you can see the angles from which the LED will
go off. Then centre the detector into the middle of this detection envelope and re-tighten the four
screws.
