General Care and Maintenance

NOTE: THIS GAME MUST ONLY BE SER-

VICED BY QUALIFIED SERVICE PERSON-

NEL.

CAUTION: THERE ARE HIGH-VOLTAGE

PARTS IN THIS GAME. BE CAREFUL

WHEN SERVICING THE INSIDE OF THE

GAME. THE GAME SHOULD ALWAYS BE

UNPLUGGED BEFORE SERVICING.

Touchscreen/Joystick Calibration

How To Calibrate:

• Find the CALIBRATE button on the OSD

board inside the CPU section, and

press it to enter screen calibration

mode.

• Touch the center of the first cross that

appears. Once you release your

finger, a second cross will appear.

NOTE: You must hold your finger on

the cross for approximately 2 seconds

for the calibration to be recognized.

• Touch the center of the second cross

that appears on the screen.

• Once the second cross is touched and

released, another cross will appear on

the screen. To test the calibration of

the screen, touch the cross with your

finger and slowly drag your finger

around the screen. The cross should

follow your movement.

• Touch the EXIT button.

The game will prompt you to go through the

same steps two more times.

• The game will then prompt you to cali-

brate the joystick. First, select the joy-

stick model on your game by touching

regulations, for which the operator assumes

full responsibility. Furthermore, players who

pay by credit card in the new country will be

surprised with currency exchange fees,

which will likely lead them to call their credit

card companies, dispute the charge, and

obtain a charge reversal. The net result will

be a credit card payment refund to the play-

ers, which will hurt revenue.

Electronics Tray

The electronics tray houses the

motherboard, I/O board, OSD board, hard

drive, power supply and the main harness.

Unlock and open the rear door to access

the tray (see Figure 34).

To completely remove the tray from the game

the rear cover must be removed. To remove

the cover, turn off and unplug the unit and

reach under the center of the top of the

cover to locate the rotary draw latch (see

Figure 34). Turn the wing on the latch coun-

terclockwise to disengage, then unscrew

the thumbscrew located in the center of the

bottom of the cover (see Figure 34). Slowly

lift the cover and disconnect the ground wire

attached to it. To remove the tray, unscrew

the thumbscrew located in the middle rear

of the tray (see Figure 34), disconnect the

VGA connector and the touchscreen con-

nector from the motherboard and discon-

nect the power cord from the power supply

and slide the tray out of the chassis.

Located on the OSD board on the electron-

ics tray are two buttons, SETUP and CALI-

BRATE (see Figures 34 and 39). Pressing

the SETUP button will bring you to the Mega-

touch Setup Screen. See the next section

for calibration instructions.

Monitor Access

To gain access to the LCD monitor, remove

the screw at the top of the marquee on the

front of the game (see Figure 34); also re-

2

move the two screws on the rear of the

monitor and the center security screw (17”

games) or nut (19” games) inside the chas-

sis securing the monitor enclosure (see Fig-

ure 34).

NOTE: To access the security screw or

nut, the rear cover must be removed.

For instructions on how to remove the

cover, see the previous section.
