and to calibrate and verify the Touchscreen. 
VIDEO TEST  
Choose this test group to examine the CRT linearity, uniformity, or color characteristics. 
SOUND TEST  
Check the audio components with game sounds and music. Have you heard them all? 
SWITCH TEST  
Manually test of currency acceptors, cabinet SETUP and CALIBRATE switches. 
CALIBRATE 
Set the Touchscreen Controller coordinates to correspond to fixed screen locations. 
CALIB. TEST  
Verify Touchscreen sensitivity and linearity for the entire active Touchscreen area. 
RETURN 
Revert to the main menu screen. You can then return to Attract Mode. 
TYPICAL DIAGNOSTICS SUBMENU SCREEN 
These routines provide you with a means of keeping the Touchmaster
® in top operating condition. Perform 
these tests on a regular basis. Players may lose interest if they have to compensate for screen 
maladjustments, in addition to remembering the rules of the game. All of these tests are brief, and may be 
done in any order. 
W hen you make adjustments to the Touchmaster
® calibration settings, the values are stored in memory. 
The game is very stable and retains its accuracy if not moved from the spot where it was last calibrated. 
However, the internal electronics cannot compensate for changes in nearby magnetic and electrical fields 
that may occur when the game is relocated to another position. 
Verify the calibration each time the Touchmaster
® is moved, in addition to the regular maintenance 
checks, for best game performance. 
You can run the Calibrate routine without going through the Menu System by pressing the CALIBRATE 
button in the coin vault. However, this omits the Touchscreen Controller tracking test. The CALIBRATE 
button was included to encourage a quick check of the touchscreen functions each time the cash door is 
emptied.

VIDEO TEST 
Video tests provide patterns which verify monitor performance or making adjustments. You can modify 
some monitor characteristics using the monitor controls remote board. 
ALIGNMENT GRID 
Lets you check or adjust monitor convergence, linearity, and dynamic focus. 
GRADIENT TEST  
Permits you to optimize CRT screen image for brightness and contrast. 
COLOR BARS 
Lets you analyze red, green, blue, and white balance. 
RED SCREEN 
Solid red screen for purity tests. Red should be the only color showing. 
GREEN SCREEN  
Solid green screen for purity tests. Green should be the only color showing. 
BLUE SCREEN 
Solid blue screen for purity tests. Blue should be the only color showing. 
TYPICAL VIDEO TEST MENU SCREEN 
It is vital that the information on the video display for the Touchmaster
® is accurate, since the CRT screen 
is also the control panel for this game. Use these test patterns often to ensure precise game images. 
Game players tend to be more critical when they are close to the monitor, and the Touchscreen Controller 
requires intimate screen contact. This is especially true of small screen versions, since some of the 
sensor areas are the same size as the contact area of the player’s fingers. 
The ALIGNMENT GRID fills the screen with a series of lines and dots. The lines and dots should be all 
one color, with no fringes or parallel images. The lines must be straight and the dots very nearly round. 
Two color bars should be visible at the center of each screen edge. These bars verify scan size. 
The GRADIENT TEST covers the screen with shades of colors to verify red, green, blue, and white level 
dynamic adjustments. Each color bar should appear sharp, clear, and distinct from the others. This test 
indicates a need for adjustment if some of the bars appear to be missing or blend together at the edges. 
The COLOR BARS screen displays each of the standard colors and shades produced by the game’s 
video circuits. The vertical bars must be uniform from top to bottom. The horizontal bars should show 
small changes in intensity or shade from side to side. A sudden transition in any bar indicates a fault. 
RED, GREEN, and BLUE SCREENS fill the screen entirely with 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. These tests verify that the black level, degaussing, and blanking circuits are correct.

SOUND TEST 
Sound test allows you to ensure that audio components are connected and operating properly. 
STOP
  Ends selected sound. You can halt repetitive sound tracks with this button. 
PLAY
  Starts selected sound. You can start another sound while one is still playing. 
BACK
  Selects previous sound choice. Each single touch decrements counter by one. 
NEXT
  Selects next sound choice. Each single touch increments the counter by one. 
  
+  Raises volume of the sound in steps until the maximum value is reached. 
  -  Lowers volume of the sound in steps until the minimum value is reached. 
RETURN
  Reverts to previous screen. Touching RETURN again takes you to SYSTEM SETUP menu. 
Touching EXIT at this point takes you back to Attract Mode. 
TYPICAL SOUND TEST MENU SCREEN 
Each sound is stored in a discrete memory location. All sounds are available to test the audio reproduction 
capabilities of the sound circuits. Vary the volume as you sample these sounds to determine if loose wire 
connections, faulty memory, digital-to-analog conversion problems, a defective speaker, etc. could be 
causing distorted or missing sound effects. Select a repetitive sound track and a high volume level if you 
suspect errors caused by heat or time-related problems. 
The sounds may be examined in any order. Touch + or -  to change the volume as necessary. Touch 
RETURN  to end these tests and go back to DIAGNOSTICS, then RETURN  and EXIT  to go back to 
Attract Mode. 
There are three types of Touchmaster
® sounds. Short bursts of sound indicate single events such as 
touch selection or an incorrect answer to a question. A dog barking, a cowbell, and the “boing” are 
examples of these sounds. Medium-length phrases announce start or end of game, bonus rounds, or new 
high score. Phrases can last from one to five seconds. The final group consists of repetitive sounds like a 
jazz-drum riff or a ticking clock. These sounds distract players and attract others. 
 
NOTICE: 
Volume adjustment in sound tests is same as one used for game play. Be sure 
to set volume back to a reasonable level when you conclude tests. 
 
NOTICE: 
There is a master volume control on the CPU Board Assembly. Change this 
potentiometer only if there is not enough range in the on-screen volume adjustment. 
Refer to audio Troubleshooting.

Switch tests allow you to manually check each switch. Touchscreen uses a digital controller to sense 
player input and it has a separate test (refer to Calibrate steps). 
OPEN  
Indicates a circuit with no continuity. This is a Normally Open switch condition. 
CLOSED 
Indicates a circuit with continuity. This is a Normally Closed switch condition. 
RETURN
  Reverts to the Submenu screen. Touch RETURN  again to go to the Main Menu. 
TYPICAL SWITCH TEST MENU SCREEN 
Touchmaster
® electronics expect all switches to be Normally Open except when activated. 
Each line item on screen represents an input signal from currency acceptors or pushbutton switches. The 
screen above is correct for a Touchmaster
® with CALIBRATE pushbutton depressed and held. The Video 
Game Machine detects and displays status of each switch independently, allowing you to check switches 
for interaction or incorrect programming (as with electronic currency acceptors). 
Touchmaster
® audio circuits also generate a clunk noise as switches close to help you locate shorted or 
intermittent connections when you are not in position to view monitor screen. 
To install a coin mechanism that accepts a type of coin different than previously used, turn off AC power 
and open Cash Door. Remove existing mechanism and install alternate unit. After mounting and 
connecting new mechanism, match Touchmaster
® software to new currency values. Turn AC power on 
and verify Touchscreen operation. Recalibrate Touchscreen. 
Check switch operation for Currency Acceptors as follows: press SETUP pushbutton to display Menu 
System. Choose DIAGNOSTICS, then choose SW ITCH TEST  to go to switch menu screen. A typical 
game SW ITCH screen is illustrated; your Touchmaster® may have a different compliment of acceptors. 
Press and hold CALIBRATE pushbutton. The Touchmaster
® emits CLUNKing sounds and indicate switch 
is CLOSED on screen. Release button to stop the sound and revert to OPEN state. Repeat steps for other 
switches in VGM. W hen finished, choose RETURN  and EXIT  to quit. 
 
NOTICE: 
Continuous clunk noises can indicate wiring defects, jammed switch, bad IC, 
etc.

CALIBRATE 
This procedure lets you correct the accuracy of the Touchscreen controller. 
  Dot for controller calibration. This sets the ability to correctly recognize a player’s touch. 
TYPICAL CALIBRATION SCREENS 
  Box for controller verification. This verifies the Touchscreen accuracy in critical areas. 
TYPICAL CALIBRATION TEST SCREEN 
The Touchscreen Controller in the Touchmaster
® senses the position of your finger based on its 
capacitance. The Touchscreen uses a very weak uniform electrical field. Touching the screen disturbs the 
field. The controller tracks the disturbance and translates it into a location. The game electronics interpret 
the location information into commands. The process occurs in a fraction of a second, allowing the game 
to respond rapidly. 
W hen the Touchmaster
® is moved from one location to another, the amount of capacitance changes. This 
causes the controller to shift its tracking coordinates and may generate errors in some screen areas. The 
Calibration routine allows the controller to adjust its tracking to match the touch point. 
Calibration screens require you to touch one specific location as indicated by a single dot. Touch the dot 
and hold this position until coarse tracking adjustments are completed (about two seconds). The 
Touchmaster
® automatically advances to the next screen and emit a short burst of sound. Repeat this 
procedure for each screen with a single dot. The Calibration Test screen (see next page) tracks finger 
position over the entire screen, allowing the entire playing surface to be checked for accurate calibration. 
Verification screens require you to touch several locations as indicated by several boxes. Touch each box 
and hold this position until fine tracking adjustments are completed (about one second). The 
Touchmaster
® displays one vertical and one horizontal line on the screen. The lines should intersect over 
the box when you remove your finger. Repeat this procedure for each box on the screen.

CALIBRATE TEST 
This test verifies touch tracking for the entire active screen area and lets you detect any calibration errors. 
 +  Intersecting lines indicate screen location coordinates from the Touchscreen Controller. 
RETURN
  Returns you to the previous screen. 
 
TYPICAL CALIBRATION TEST SCREEN
 
Check the accuracy of the Touchscreen Controller can be checked without going through a new 
calibration procedure. This test quickly detects any non-linear or unresponsive areas of the Touchscreen. 
The Controller Version number indicates the model of controller used in this unit. Because of space 
limitations, the Touchscreen Controller is mounted where these numbers may be difficult to view easily. If 
customer assistance is required, the service person may request this number during problem solving. 
The first time the Touchscreen Controller is calibrated, the tracking data is stored in a section of the 
Touchmaster
® memory. Each time the screen is touched this information is recalled. This data must be 
changed if the game has been serviced or relocated. The test does not change the data stored in 
memory. The only way to replace the existing data with new information is to go through each of the 
calibration steps. Use Calibrate Test on a regular basis to determine if a new calibration is necessary. 
1.  Touch CALIBRATE TEST  to view the test screen. The lines should intersect at the screen’s center. 
2.  Touch any location on the screen. The lines intersect at the point of contact. 
3.  For each additional touch point, the lines must intersect under your fingertip. Drag your finger across 
the screen, as well as lift it from the screen and place it down again. 
4.  Check several locations, especially along the outer perimeter of the screen. If either or both lines are 
visible beside your finger after the lines stop moving, recalibrate the touchscreen. 
5.  Touch RETURN  to end the test and go back to the DIAGNOSTICS screen. If you encountered errors 
in the test, choose CALIBRATE and complete each step. 
6.  W hen the CALIBRATE TEST results are satisfactory, select RETURN  to go to the main menu and 
EXIT  to return to Attract Mode. 
NOTICE: 
Always recalibrate and test Touchmaster® after moving it.

MAINTENANCE 
Touchmaster® uses the same surface for video display and player controls. Because players use their 
fingers, the entire screen and cabinet will quickly become covered with fingerprints. W e recommend that 
you clean the screen and cabinet frequently to ensure maximum customer interest. 
 NOTICE: AVOID ABRASIVE CHEMICALS. 
Do not use products with ammonia, bleach, 
lemon, vinegar, trisodium phosphate (tsp), or any abrasive ingredients. These products 
can damage the surface of the Touchscreen and degrade performance. 
♦ Glass surfaces
 
You may clean glass while power is on. Apply a mixture of isopropyl alcohol and warm water to a 
clean cloth or sponge, then use this to wipe screen. Do not apply the cleaner directly on the glass! 
Liquids could drip down into the Touchscreen circuits and cause erratic operation. 
♦ Calibration
 
Calibrate the screen each time you clean the screen. Use the Calibration Test steps to determine if 
recalibration is required. 
 
SERVICING 
W e recommend you read the Safety Notices section thoroughly before beginning service. 
Touchmaster
® uses complex electronic components that are very sensitive to static electricity. Observe 
the following precautions prior to handling any of the electronics. 
1.  Ensure that AC power is off prior to servicing the electronics. 
2.  Discharge any static electricity build up in your body by touching the metal cabinet base. Do this 
before touching or handling electronic assemblies. 
3.  Store the electronic assemblies in an anti-static area. Use anti-static bags to store electronic 
assemblies. Reuse the bag to store removed boards during service. 
4.  Do not remove or connect any electronic assemblies when AC power is on. Doing so will damage the 
electronic assemblies and void the warranty. 
5.  Always replace ground wires, shields, safety covers, etc. when maintenance or service is completed. 
Ensure that all ground and mounting screws are installed and tightened firmly. 
Refer to the original equipment manufacturer’s manual for information relating to the removal and 
installation of approved parts for the following components.
