Touchmaster® Conversion Kit System - 21 SWITCH TEST Switch tests allow you to manually check each switch used in the game. Because the Touchscreen uses a digital controller to sense player input, 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 Sub Menu screen. Touch RETURN again to go to the Main Menu. TYPICAL SWITCH TEST MENU SCREEN The Touchmaster ® game electronics expect all switches to be Normally Open except when activated. Each line item on the screen represents an input signal from the currency acceptors or the push button switches. The screen above is correct for a Touchmaster ® with the Calibration button depressed and held. The game detects and displays the status of each switch independently, permitting switches to be checked for interaction or incorrect programming (electronic currency acceptors). In addition to the on-screen OPEN or CLOSED indication, the Touchmaster ® audio circuits generate a clunk noise each time a switch is closed. Use this to locate shorted or intermittent connections when you are working from the back or sides of the cabinet and cannot see the monitor screen. Example: Suppose a different coin mechanism must be installed to accept another type of coin than was previously used. Turn off the game power and open the Cash Door. Remove the existing mechanism and replace it with the alternate unit. After the new mechanism has been mounted and connected to the game electronics, the game must be matched to the new currency values. Power up the game and verify the Touchscreen operation (minor calibration may be required after any type of product service). Check switch operation for the game Currency Acceptors in the following manner: Press the SETUP pushbutton to display the Menu System. Choose DIAGNOSTICS to get to the Sub Menu, then choose SW ITCH TEST to go to the switch menu screen (a typical game SW ITCH screen is illustrated; your Touchmaster ® may have a different compliment of Acceptors). Press and hold the CAL. push button. The Touchmaster ® emits CLUNKing sounds and indicate this switch is CLOSED on the screen. Release the button to stop the sound and revert to an OPEN state. Repeat these steps for other switches in the game. W hen finished, choose RETURN and EXIT to quit. NOTICE: Continuous clunk noises can indicate wiring defects, jammed switch, bad IC, etc. SWITCH TEST J2 – 10 M.

System - 22 Midway Amusement Games, LLC 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.

Touchmaster® Conversion Kit System - 23 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 re-calibrate and test the VGM after moving your Touchmaster®. CONTROLLER VERSION X.XX RETURN
