2. PRECAUTIONS
2-1 Cautions When Installing
This game is designed for indoor use only. The game must not be installed out-
doors or under the following conditions:
a. In areas directly exposed to sunlight, high humidity, direct water contact, dust,
high heat or extreme cold.
b. In locations that would present an obstacle in case of emergency, i.e. near tire
equipment or emergency exits.
c. On an unstable surface or floor subject to vibration.

2-2 Caution When Handling
a. AC power must always be turned OFF, and the game unplugged, before
replacing any parts or connecting/disconnecting connectors.
b. When unplugging the game from an elecnical outlet, always grasp the plug,
not the cord.
c. Do not subject game to physical shock when transporting or moving it.
d. The power supply range is between 1 lo-120VAC, (switchable to 220 VAC).
e. The cabinet must be grounded with a securely connected ground plug.
f. Care must be taken at all times to avoid electrical shock whenever inspecting
or adjusting the game, particularly around the monitor.
g. Always return the leg levelers to the extreme “up” position before moving the
game, and separate the game into its two assemblies - monitor cabinet and
seat.
h. Adjustment is required whenever the game PC board, ROM, Joystick, Throttle
Control or other potentiometers are changed.
i. DO NOT attempt to repair the Printed Circuit Board (PCB). It contains
sensitive chips that could easily be damaged by even the small internal voltage
of a multi-meter. Always return the PCB to your distributor for any repairs.
2-3 Caution When Handling Rear Projection Screen
The rear projection screen is easily damaged, or deformed, unless proper care is
given to it’s care and cleaning.
a. The screen should generally be cleaned by wiping gently with a soft cloth.
b. If extremely dirty, wet a cloth with a mild solution of neutral detergent and
water, wring dry, and wipe gently. Finish with a soft dry cloth.
c. Never:
lUse any chemical cleaners like paint thinner, benzine etc.
lUse any alkaline or acid based detergent.
l Apply any volatile matter such as insecticide.
.Leave the screen in contact with rubber or vinyl products for any extended
time.
3. INSPECTION
The AIR COMBAT Game cartons should be carefully inspected upon receipt to
insure that the game is complete and was delivered in good condition.
Inspect the game cabinet by doing the following:
1. Examine the monitor cabinet exterior and seat assembly for dents, chips, or
broken parts.
2. Open the side service door and the coin door on the seat assembly as we’ ” the
back cover of the monitor cabinet, and inspect the interior as follows:
2

Verify that all plug-in connectors are firmly plugged in. DO NOT force
connectors together. The connectors are heyed so they fit only in the proper
orientation. A reversed edge connector can damage a PCB and will void your
warranty.
Inspect the power cord to insure that there are no cuts or dents in the insulation.
Inspect the power supply connectors.
Inspect other major sub-assrmblie~. such as the rear prqjection monitor, PCB,
leg levers, and speakers. Make sure that they are mounted securely and that all
ground wires are firmly connected.

6. HOW TO PLAY
l AIR COMBAT is a game that assigns the player a mission to shoot down and destroy
all enemy fighters that appear on the screen. The player has both a machine gun and
missiles that are fired by using two separate control buttons.
l After inserting the proper coin(s), a player first selects a game difficulty level
(CADET, CAPTAIN or ACE) by moving the lever left or right within the time
allotted as shown on a display in the center of the screen. If no level is selected, one
is assigned automatically.
l The player starts the game by pushing the start switch located on the cockpit console,
l Enemy fighter planes appear one at a time.
l The player attempts to shoot them down using the machine gun and missiles. The
machine gun is fired with each pull of the trigger. If a player keeps the trigger
depressed, the gun fires continuously. Missiles must be “launched” individually.
l The player’s missiles are limited in number, but there are enough machine gun
“bullets” for the time alloted to the entire game. No more than two missiles can be
fit-cd at one time.
l The player’s rank is determined by his/her proficiency in playing the game.
- The three levels are:
CADET- This is a training mode for players lcaming the game. The player can clear
this level easily using only missiles. The game pauses occassionally to
provide hints on how to play. ‘The messages can bc bypassed by pressing the
missile and machine gun buttons simultaneously. The game ends when six
enemy aircraft have been dcstroycd. No rank is awarded.
CAPfAIN - This is a difficulty level in which the player rcccives no hints on how to play.
If a player shoots down four enemy aircraft, the battlc sccnc changes from
over land to over water. If the player shoots down all six aircraft, the game
ends. The player’s rank is indicated. Players can increase their ranking by
destroying the enemy aircraft with the machine guns.
This is a difficulty lcvcl which a player cannot clear withoul mastering the
USC of the machine gun. If a player shoots down three aircraft, the sccnc
changes from land to sea.
When the player shoots down three mom cncmy aircraft (a total of six), the
player is allowed to attempt a landing on an aircraft carrier. If the player
fails the landing, the game is over. Howcvcr, if player lands successfully,
the strongest cncmy of the game appcam for the final stage. If the player can
shoot down that cncmy, the game ends, and the player is awarded the top
rank of “Commander-in-Chief’.
l The game is over when a player shoots down
(operator adjustable) runs out.

TROUBLESHOOTING - GENERAL
If you suspect the game may be malfunctioning, the following steps should be taken
before you make a service request.
(1) Check to see that the circuit breaker is properly set.
(2) The power supply should be set to either 1 IO or 220 Volts AC. However, when some
other equipment (air conditioner, multiple pinball games, air compressors, etc.) are
^ ^^..^^.^ .A .^ .I... I^-^ - ^._.^_ -..-- 1.. rL- ..-I . ..-- --.. -L- .-. L-
CVIIIIF;CLFU LU ~11s ~amc; ~UWGL wppy, wc vwrdgc ~ltay warge ueyond this rdnge and
cause game trouble or improper operation.
(3) When the game does not work with the power turned on, turn the power off, wait ten
seconds, then turn the power back on. This may restart the game. If it still does not
work, inspect the fuse.
(4) When the game PCB, the ROMS, Joystick, Throttle, or Potentiometers are replaced, it
is necessary to make initialization adjustments to play normal games. Make appropri-
ate adjustments referring to section 54.
(5) Check all wiring connections as malfunctions can be caused by loose connections.
(6) Foreign substances or dust on the game PCB or on the monitor PCB, may cause
malfunctions or improper operation. Check that the PCBs are clean.
(7) When you make electrical checks, use the wiring diagrams for reference.
* If the above suggestions are not applicable, or no improvement is observed, contact
your distributor or the service office printed on the back cover of this manual.
* DO NOT ATTEMPT TO REPAIR THE GAME PCB YOURSELF. Instead,
please return the board to your distributor for any repairs. The PCB contains
sensitive chips that could be destroyed even by the internal voltage of a multimeter.
* When sending parts to be repaired, make sure to pack them firmly with a complete
explanation of the problem. When sending PCBs, package them in anti-static
foam or bubble wrap, and pack them in cardboard boxes to protect against impact
damage during shipment. To ship monitors, pack them in wooden frames so that
CRT’s and PCBs are protected against excess load.
