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.
