July, 1981  
This booklet provides operation, auditing, adjustment, and diagnostics for DEFENDER.  
POWER TURN ON  
With power first applied, a sound is produced, general illumination comes on, and random  
patterns appear on the CRT as the game sequences through RAM, ROM, and battery checks.  
The game then comes up in game over. Messages are displayed for RAM or ROM failures;  
refer to Power Up and Reset RAM/ROM Tests. If the game comes up in Bookkeeping, turn the  
game OFF and back ON.  
a.  
If the game now sequences through the tests and then comes up in game over, the  
bookkeeping totals have been reset to zero.  
b.  
If the game still comes up in bookkeeping, open coin door and turn the game OFF and  
ON. The game will now sequence through the tests and come up in bookkeeping. This is an  
indication of battery failure and the game has reverted to factory settings. To return to  
game over:  
1. Set switch to MANUAL-DOWN.  
2. Depress ADVANCE to display Function 28.  
3. Set switch to AUTO-UP and depress ADVANCE.

SOUND BOARD DIAGNOSTICS  
Depress DIAGNOSTIC pushbutton on the bottom of the Sound Board. A check is made of the  
Sound ROM and sounds are produced if the check is good. If sounds are produced but not  
produced in Audio Test 5 check for ROM board PIA outputs on Sound Board inputs that is  
stuck low. If no sound is produced either the Sound ROM, input power, or other Sound  
Board circuitry is faulty.
