Diagnose Code Wheel – Bay-Tek Version
The Code Wheel, attached to the back side of the wheel, must work properly to identify slot
location and ticket payout.
To check for proper operation;
1. Shut off power to the game.
2. Set dipswitch #8 bank 2 (S2) to the ON position.
3. Turn power back on.
4. Press the red “Reset” button on the ticket tray for 5 seconds. This will start the diagnostic
program.
5. The ticket display will count up from zero to 15.
6. If a slot number is skipped each time the wheel rotates past the coin slot hole, that means
that the position code wheel is faulty and must be replaced.
7. Replace the wheel assembly and retest.
8. Be sure to turn power off to the game before moving the dipswitch to Off.
