3. Calibrate the sensor:
CAUTION
Do not adjust sensitivity too far, or unreliable sensing could result.
a. Using a piece of WHITE poster board or heavy cardboard, make a 5" x 5-5/8" target.
NOTE
It is very important that this material be white.
b. Place the target in the cup station just beyond the cup deflectors (see figure B-2). The target
should be standing vertically; not tilted forward or backward.
c. With the target in place, turn the adjusting screw clockwise very slowly until the indicator just
turns ON.
d. Turn the adjusting screw counterclockwise very slowly until the indicator just turns OFF.
4. Replace the plastic cap.
5. Insert a mug into the cup station in the vending position and check to see that the red indicator
light is ON.
This calibration will be adequate for most cups or mugs. In some cases, a slightly more sensitive
setting is needed if the cup or mug is a dark color.
