IV. BOOKKEEPING FUNCTIONS-KEYBOARD
DISPLAY UNIT (KDU)
A. ELECTRONIC
A large part of the design effort realized in the game is devoted to help the operator perform
accounting tasks.
Bookkeeping functions are obtained and displayed by means of a hand held Keyboard Display
Unit (AS-3051) supplied with the game. For use, connect the attached extension cable to terminal
J23-B, which is located just inside and slightly left of the cabinet door.
There are two states of operation for the Bally Electronic Bingo game. One is the normal (play)
mode and the other is a diagnostic mode obtained by pressing the KEYBD/CL R button on the Key
board Display Unit (KDU). When not in use, the KDU may be left connected and stored in the front
cabinet.

To return game to the normal (play) mode, depress the "Game" button.
Caution: Position the KDU and cable carefully in the cabinet to avoid moving parts and terminals.
To view a particular function, switch the game to the diagnostic mode as described and enter the
code unique to that function on the keypad. The value contained in the memory reserved for the
function will then be displayed.
