The correct adjustment & synchronization of the Switches controlled by Cam No. 's l0A & 12 is
vitally important to the Replay Counter Circuit. Out of adjustment Back Switches (12-C & lOA-A) can
cause the four Replay Counters to become overloaded & burn out (affects the Printed Circuit Disc). Fig
ure 3 shows these Cam Switches in a proper "Made" position. The Back Switches are adjustable. Note
that the 12-C switch closes first & opens last. Cam Switch 12X is used for our testing purposes only.
