All the electronics and sensors are placed on one board located behind the exit door at the side of the
hopper. Slide the yellow button to the opposite position and remove the exit door where the electronics
are mounted. All dirt must be cleaned with a soft moistened cloth. Isopropyl Alcohol is recommended
for cleaning excessively dirty exit windows.
Warning: Be careful when re-inserting the board back in the hopper not to damage the cable located at
the back of the board!
Low Coin Contact Plates
Looking inside the hopper through the top opening locate the two brass plates at the bottom of the
hopper. If they appear to be dull and/or dirty remove the right section of the hopper by removing the 6
screws on that side. Use a Scotch-Brite pad, or another item made with abrasive material, to scrub the
oxidation and dirt off of the brass plates.
