SERVICING

Only qualified service personnel should repair VGM equipment. The following product guidelines apply to all video game operators and service personnel. Notes, cautions and warnings appear throughout this manual where they apply. Study the Safety pages before beginning service.

Battery

CAUTION: If you install the battery incorrectly, it may explode! Avoid direct shorts across the terminals or from terminals to ground. These batteries are designed for very long life. Don’t attempt to recharge these batteries!

CAUTION: Avoid an explosion! Replacement batteries must match the originals in size, voltage rating, and composition. Manufacturer recommended equivalent types are acceptable. Store batteries in a safe place until you’ve completed repairs. Dispose of used batteries according to manufacturer instructions.

A battery on the CPU Board retains data in memory during power disruptions. This battery is a 3-volt, lithium button cell of type CR 2032. Switch off power to the game. Unlock and remove the rear door. Remove the back of the Arcade Computer. The battery resides toward the edge of the motherboard, near the daughter board sockets. Carefully pry up the battery retaining lever. Then grasp the battery edges and remove the device. Set the battery aside.

Note the “+” marking on one side of the replacement battery. When you install a battery, this “+” marking must face the battery retaining lever. After replacing the battery, set the system clock to the correct date and time. Also enter the Menu System and check or update system adjustments as necessary.

Coin Counter

Switch off power to the VGM. Unlock the cash door and swing it open. Find the meter at the lower left corner of the vault opening. Record the meter count before testing or replacement.

Locate the meter wires. Disconnect wiring at the connector. Remove two screws from the front bracket. The meter is a 5V D.C. meter. Assure that the replacement meter has a diode across the terminals to protect driver circuits.

Coin Mechanism

Switch off power to the VGM. Unlock the coin door and swing it open. To clean or replace a coin mechanism, unlatch and remove it. After reinstallation, assure that the mechanism seats fully in its bracket. Close and lock the release latch. Then close the door. Enter the Menu System to change the coin mechanism setup. Test known good and bad coins to verify operation.

CPU Board

NOTICE: Avoid damage to electronics! Turn off VGM power before servicing circuit boards or any electronic assembly. Never “hot plug” circuit boards.

The CPU Board is part of the Arcade Computer. Switch off power to the VGM. Open and remove the rear door. The Arcade Computer is behind this door.

To expose the CPU Board, loosen four metal thumbscrews. Don’t remove the screws. These screws reside at the top and bottom corners of the case. Slide off the back of the computer. Disconnect the floppy disk power and data cables at the disk drive. Loosen the drive mounting screws. Lift the floppy drive out of the cabinet. Set it aside for reassembly. Remove the I/O Board brackets.
