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.

The color bar pattern is also analyzed to detect color RAM faults. If Color RAM
Test 4 indicates no faults, a double-width band, half width bands, transposition or
missing bands indicates a fault in 2I, 1L, or 1O chips.
To return to game over:
l. Depress ADVANCE in AUTO-UP. Audit function 1 is displayed.
2. Set switch to MANUAL-DOWN and depress ADVANCE. Special Adjustment Function 28 is
displayed.
3. Set switch to AUTO-UP and depress ADVANCE.
INITIATING AUTO-CYCLE MODE
1. Set switch to AUTO-UP and depress ADVANCE. Audit Function 1 is indicated on CRT.
2. Set switch to MANUAL-DOWN and depress ADVANCE to indicate SPECIAL FUNCTION 28 on
CRT.
3. Set switch to AUTO-UP and operate HIGH SCORE RESET to indicate 15 on CRT for
Function 28.
4. Depress ADVANCE. The game sequences through ROM, RAM, Sound tests and monitor
test patterns.
5. To exit the AUTO-CYCLE mode, depress ADVANCE in AUTO-UP.
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.
