SAFETY INSTRUCTIONS  
The following safety instructions apply to operators and service personnel. Read these instructions before  
preparing the game for play. Other safety instructions appear throughout this manual.  
DEFINITIONS OF SAFETY TERMS  
DANGER indicates an imminent hazard. If you fail to avoid this hazard, it WILL cause death or serious  
injury.  
WARNING indicates a potential hazard. If you fail to avoid this hazard, it COULD cause death or serious  
injury.  
CAUTION indicates a potential hazard. If you fail to avoid this hazard, it MAY cause minor or moderate  
injury. CAUTION also alerts you about unsafe practices.  
NOTICE indicates information of special importance.  
WARNING: TRANSPORTING GAMES. This game contains glass and fragile electronic  
devices. Use appropriate care when transporting this game. Avoid rough handling when  
moving the cabinet. Do not move this game with the power on.  
WARNING: DISCONNECT POWER. Always turn the power OFF and unplug the game  
before attempting service or adjustments unless otherwise instructed. Installing or  
repairing PC boards with power ON can damage components and void the warranty.  
WARNING: GROUND GAMES. Avoid electrical shocks! Do not plug in a game until you  
have inspected and properly grounded it. Only plug this game into a grounded, three-  
wire outlet. Do not use a “cheater” plug, or cut off the ground pin on the line cord.  
WARNING: AVOID ELECTRICAL SHOCKS. This video game system does not utilize  
an isolation transformer. Internal cabinet AC is not isolated from the external AC line.  
WARNING: HANDLE FLUORESCENT TUBE AND CRT WITH CARE. If you drop a  
fluorescent tube or CRT and it breaks, it will implode! Shattered glass can fly eight feet  
or more from the implosion.  
CAUTION: CHECK POWER SELECTOR, LAMP. Set the 115/230VAC selector on the  
power supply for the correct line voltage. Check the selector setting before switching on  
the game. Verify that the fluorescent lamp assembly is correct for the local line voltage.  
CAUTION: USE PROPER FUSE. Avoid electrical shock! Replacement fuses must be of  
the same type as those they replace. Fuse voltage and current ratings must match  
ratings on the original fuse.  
CAUTION: ATTACH CONNECTORS PROPERLY. Be sure that printed circuit board  
(PCB) connectors mate properly. If connectors do not slip on easily, do not force them. A  
reversed connector may damage your game and void the warranty. Connector keys only  
allow a connector to fit one set of pins on a board.

CAUTION: USE CARE WHEN SHIPPING HARD DISKS. The hard disk drive must be  
packed in an anti-static bag. When shipping the drive for repair or replacement, pack it in  
an approved container (P/N 08-8068). Do not stack or drop hard disk drives.  
WARNING: HAZARD TO EPILEPTICS. A very small portion of the population has a  
condition which may cause them to experience epileptic seizures or have momentary  
loss of consciousness when viewing certain kinds of flashing lights or patterns that are  
present in our daily environment. These persons may experience seizures while  
watching some kinds of television pictures or playing certain video games. People who  
have not had any previous seizures may nonetheless have an undetected epileptic  
condition.  
If you or anyone in your family has experienced symptoms linked to an epileptic condition  
(e.g., seizures or loss of awareness), immediately consult your physician before using  
any video games.  
We recommend that parents observe their children while they play video games. If you  
or your child experience the following symptoms: dizziness, altered vision, eye or muscle  
twitching, involuntary movements, loss of awareness, disorientation, or convulsions,  
DISCONTINUE USE IMMEDIATELY and consult your physician.

PRODUCT CONFIGURATION  
♦ Stand Alone Units  
Each game is ready to play right out of the box. Operators may use the menu screens in the game  
menu system to determine some player variables in advance or leave the choices up to the players.  
♦ Linked Units  
Linking allows players to compete against each other (on one course). Operator menus are the same  
as in stand alone games. Crossover couplers and linking cables to connect two games are factory  
installed. Use the optional Hub Linking Kit to interconnect up to eight games (two groups of four).  
MAINTENANCE  
♦ Viewing Glass  
It is not necessary to switch off power to the game to clean the glass. Apply a mild glass cleaner to a  
clean cloth or sponge, then use this to wipe the viewing glass. Do not apply the cleaner directly on  
the glass! Liquid could drip down into switch or control circuits and cause erratic game operation.  
♦ Player Controls  
Use plastic-safe non-abrasive cleaners to avoid damage. Apply cleaner to a clean cloth or sponge,  
then use this to wipe the player controls. Do not apply the cleaner directly on the controls!  
♦ Cabinet  
Use plastic-safe non-abrasive cleaners to avoid damage. Apply cleaner to a clean cloth or sponge,  
then use this to wipe the cabinet. Do not apply cleaner directly on artwork or cabinet!

GAME OPERATION  
DESIGN PHILOSOPHY  
This game uses an “Arcade Computer” to control its functions. The “Arcade Computer” is a hybrid cross  
between the custom game computer circuits used in most games and the personal computers found in  
many offices. The “Arcade Computer” uses a familiar case enclosure with a motherboard, plug-in cards, a  
modular power supply, disk drives, etc., but it has been optimized specifically for playing this game. This  
design permits improved upgrade and service access without sacrificing game ruggedness or reliability.  
PLAYER CONTROLS  
♦
BOOST Button  
This button allows a player to begin or continue play, select tracks and boats, etc. If the Boost feature  
is active, this adds a burst of power (the button is illuminated when Boost is available during a race).  
An on-screen gauge shows exactly how much Boost fuel has been collected by a player.  
♦
THROTTLE Lever  
Controls craft speed. Push up to move forward, down to back up. Stop is a detent position in between.  
Reverse is spring loaded, but forward speeds may be maintained without attention (cruise).

GAME FEATURES  
STARTING UP  
Each time the game is first turned on or power is restored, it begins executing code out of the boot ROM.  
These self-diagnostic tests automatically verify and report condition of the CPU and the game hardware. If  
any of the individual tests fails, the game may display an error message.  
Once all Power-up tests are complete, the game goes into the “attract mode”. Scenes and sounds from a  
typical game alternate with previous high scores in an endless pattern until game play starts.  
Insert currency to start the game. Players select a boat and a track. Play begins after a countdown period.  
The game will progress until time is exhausted or play is over. If no more play is required, the game  
automatically returns to the “attract mode”.  
GAME RULES Play instructions are on the information panels over and under the video monitor.  
INDIVIDUAL PLAY  
Insert currency to start the game. Select a boat and a track. Additional game information appears on the  
screen when needed. Individual statistics are shown periodically during the race and its end.  
PLAYER CHOICES  
Any boat can be used on any track. Each boat handles and performs differently. Players will learn which  
boats are best for a given track and driving style. Press one of the VIEW buttons to select more boats.  
CONTROLLING THE BOAT  
The steering wheel and throttle control the boat. The steering wheel directs the boat while the throttle sets  
its speed. A “BOOST” button on the throttle gives an extra burst of power. This button flashes when the  
additional “BOOST” is available. In order to use “BOOST,” players must collect “BOOST” icons along a  
track by steering directly under them. A gauge shows exactly how much “BOOST” power is available.  
INDICATORS  
On-screen indicators give the players information about their boat and those of competitors. Across the  
top of the screen are numeric indicators for elapsed time, time remaining to pass the next checkpoint, and  
race position. Gauges show engine R.P.M., vehicle speed, and “BOOST” fuel remaining.  
DISPLAYS  
A superimposed radar map shows the terrain and the position of all boats, with your craft at the center.  
Computer-controlled boats are shown as green triangles, other human-piloted boats are shown as red  
triangles, and police craft are shown as blue triangles. At the bottom of the screen, another display shows  
the relative position of nearby boats.  
GAME ACTION  
Action begins when the three-two-one countdown ends and the announcer yells “Go!” Boats must pass  
checkpoints within time limitations to continue play. Players must avoid fixed obstacles and other boats to  
decrease their time between checkpoints. Ramps along the route allow players to advance more quickly,  
collect hovering “BOOST” icons, or avoid obstacles.  
Players can change their view of the action by pressing the view buttons on the left side of the control  
panel. The game includes announcer comments, engine sounds, and other noises.  
SCORING  
Players who set a speed record for any track may enter their initials in the high score table. After a certain  
number of tracks are completed (determined by the adjustments), additional tracks become available.

MENU SYSTEM  
SYSTEM OVERVIEW  
A series of on-screen menus present game variables and diagnostics. The Main Menu screen allows the  
operator to view information, make changes, or verify equipment operation. Each Sub Menu screen  
displays one specific group of choices. Detail Menus present data or run the required tests. You must be  
at the Detail Menu level to detect errors, make changes, or activate tests. The operator control switches  
are used to move through the menus, select items, and start or stop particular routines.  
Each time the game is turned on or switched from normal play mode to the menu system and back, the  
startup routine is activated. These basic system checks run automatically; their purpose is to detect those  
faults that would prevent the game or the menu system from operating properly. Messages appear on the  
screen as each item runs, including any error information. Successful startup takes less than one minute  
to complete. Write down any messages or information before proceeding to the menus or game play.  
SCREEN LAYOUT  
Each menu screen is different, but the material presented stays in the same physical location each time.  
The color bar at the top center of each screen displays the current menu title.  
The center of the screen shows data (menu items, video signals, statistics, reports, etc.)  
The bottom of the screen displays messages (explanations, control functions, revision levels, etc.)  
ORGANIZATION  
The operator must activate and deactivate the menu system manually using control switches.  
The Main Menu screen items are divided into categories: tests, statistics, audits, adjustments, etc.  
Tests can verify proper operation of the equipment assemblies one at a time.  
Other items allow operators to assess game performance and customize or return to factory defaults.  
Sub Menu screen items present the operator choices within a category. Some items have no Sub Menu  
while others may have more than one. It is always possible either to return to the previous menu or go on  
to the next menu. The instructions are usually listed at the bottom of each individual screen.  
Detail Menu screen items display specific information. The operator must command the system to get  
results or to make changes. There is always a way to go back to the previous menus from this screen.  
Switch functions are listed on each screen. Use the control switches to highlight an item on any menu.  
Only one highlighted item can be selected at a time. Press the indicated button to select a highlighted  
item. To return the game to normal play mode, use the switches to return to the main Operator Menu and  
select START THE GAME, then press TEST. The menu screens will be replaced by the “Attract” scenes.

MONITOR PATTERNS TEST (continued from previous page)  
Red, Blue, and Green Color Screen tests fill the screen with 100% of the chosen color at normal  
intensity. Each screen should be absolutely uniform from top to bottom and side to side. No retrace lines  
or noise should be visible.  
The Color Screen tests can verify monitor intensity, black level, blanking and color purity.  
Color Screens may not hold their uniformity if the monitor degaussing circuit is defective.  
White, Black, 50% Gray, and 25% Gray Screens fill the screen with black, gray or white at various  
intensities. The screens should be uniform with no color tints or distortion. No retrace lines or noise should  
be visible.  
If any of the tests shows a need for adjustment, use the proper controls on the Video Monitor.

CALIBRATE STEERING AND THROTTLE (cont’d)  
Calibrate Steering and Throttle allows the operator to set the steering and throttle mechanisms for  
optimum control during game play. Poorly calibrated player controls can reduce profits. Calibrate the

control switches to select Calibrate Steering and Throttle and press the TEST button to activate the test.  
Each of the controls has a minimum analog value of 0 and a maximum of 1.0 for its full range of motion.  
These numbers correspond to digital values from 0 to 255. Both sets of numbers must track correctly to  
achieve accurate steering of boats. When properly adjusted, the digital value will be equal to the analog  
value multiplied by 255. For example, a steering value of 0.5 (straight ahead) translates to a digital value  
of 128, exactly half way in between left and right steering wheel limits.

TROUBLESHOOTING  
NOTICE: The term VGM refers to the video game machine.  
CAUTION: This VGM uses complex electronic components that are very sensitive to  
static electricity. Observe the following precautions before handling VGM electronics.  
Failure to do so may void your warranty and could damage electronic assemblies.  
•
•
Before servicing electronics, turn off AC power to the VGM. Wait for capacitors to discharge.  
Before touching or handling electronic assemblies, discharge static electricity on your body. To  
discharge this static, begin by connecting the line cord to a grounded outlet. Don’t turn on the  
VGM! Next, touch the safety ground stud of the power supply chassis.  
•
•
•
Store electronic assemblies in an anti-static area. Use anti-static bags to store or transport VGM

SYMPTOM  
CAUSE  
REQUIRED ACTION  
1. Don’t extend linking cables that come with VGM.  
2. Install required crossover between VGM  
cabinets. Each coupler connects two cabinets  
(one pair). Don’t use standard telephone type  
couplers or wiring to link cabinets.  
Faulty wiring  
•
Can’t connect VGMs (video  
game machines) together  
3. Use only 10Base-T, Ethernet-type, Category 5,  
twisted-pair wiring for VGM data.  
Use required network hub for your local network.  
Hub Link Kit permits up to four cabinet  
connections. Cabinet array completion requires  
basic kit brackets and spacers.

adapter wires are thin and easily damaged.  
1. Inspect hub indicator lights. Each active port  
should have illuminated indicator. If cable  
connects, and that position has no lit indicator,  
check for cable continuity from hub to cabinet.  
2. Assure that no loose wires catch in hinges,  
doors, or under cabinet.  
Power problem  
Faulty wiring  
(3 or more cabinets)  
3. Verify that linking cable connects to Network  
Board at each VGM’s computer.  
4. Verify that each linking cable operates properly  
by placing it in working VGM.

properly, while others don’t  
2. Inspect hub indicator lights for link activity. See  
manufacturer’s literature for diagnostics.  
Verify that all linked cabinets use same software  
version. Otherwise, linked cabinets won’t  
recognize each other. Contact your distributor.  
1. Insert crossover connections between coupled  
cabinets. Standard couplers appear identical to  
devices supplied with cabinets, but don’t include  
internal crossover.  
Wrong software  
version  
Faulty wiring  
(2 cabinets)  
2. Verify that each linking crossover coupler  
operates properly by placing it in working link  
between two cabinets.  
1. You used additional crossover connector and  
cable to extend VGM or hub link connection.  
Two crossovers cancel and cause same  
problem as no link crossover.  
Faulty wiring  
(3 or more cabinets)  
2. Connect cables directly to hub. Don’t use  
crossover coupler and hub together in single  
network.  
3. Separate communications wiring from other  
wiring. Wires that must cross should cross at  
right angles to limit noise pickup.

WARNING: HIGH VOLTAGE. VGM (video game machine) monitors generate and store  
potentially lethal high voltages. Avoid touching any part of the monitor until power has  
been off for some time. A picture tube can maintain a hazardous charge for up to  
several days. Only qualified technicians should service monitors. Turn off the power,  
unplug the VGM and discharge the CRT before attempting service. Even properly  
discharged tubes can revert to a highly charged state, without reapplication of power.  
WARNING: In normal operation, the monitor doesn’t require isolation from AC line  
voltage. During bench servicing, you may need to operate the monitor outside the  
cabinet. If you do, isolate the monitor from line voltage with an isolation transformer.
