Selectivity adjustment The CC MC and Defender products utilize a selectivity potentiometer to accommodate a wide range of coin alloys and distributions among each alloy The selectivity adjustment allows the user to set the Comparitor to a more discriminative setting if a closely matching fraud is encountered or set to a more open setting to accept a wide range of poorly matching coins Turning the potentiometer clockwise on the CC and MC product sets the product to a more discriminative setting counterclockwise for Defender Turning the potentiometer counterclockwise on the CC and MC products allows the mechanism to accept a wider range of a poorly matched coin alloy clockwise on the Defender The factory potentiometer setting is typically set at a 9 00 o clock position arrow pointing straight left for most coins To set for the best performance acceptance of good coins coins which match the sample resident coin start with the pot at its most discriminative setting Turn the pot back counter clockwise clockwise for Defender in short increments dropping coins frequently between turns until all coins are accepted repeatedly Fine tune as necessary to accept all good coins or tokens and reject fraud coins Page 10 of 44 GADOCYPROCED0030100300009100300009R05100300009 DOC AIR BALANCE PROCEDURES FOR THE IC INTELLIGENT COMPARITOR USING THE COMPARITOR TEST STATION Preliminary setup Connect a test lead from the N
