TECHNICAL BULLETIN
QUICK & CRASH
We have become aware of a possible problem on a small quantity of games recently shipped,
whereby the Flat Target Photo Sensor may become damaged and fail to work.
P OBLEM
The Flat Target should be angled downwards by approx.10º. On some games the Flat Target
is horizontal and the Photo Sensor is hitting the Target Cover when the solenoid activates the
target. This may cause the lens of the Photo Sensor to be damaged and destroy the sensor.
Please check both Flat Targets (upper & lower) to prevent possible future problems and
maintain game income.
The following pages describe the procedure to check and if necessary correct the problem.
