SPECIAL NOTICE FOR

ALL SEGA NAOMI KITS

PROBLEM:

The SEGA Naomi Game kits are actually ‘JAMMA Dependent’. What this means exactly is they will only install into existing JAMMA Cabinets. If an operator tries to install these kits into a Non-JAMMA cabinet, they will first have to bring the wiring up to JAMMA Standards.

SOLUTION:

° Step 1 Disconnect the games original DC Power Supply. You may only use the power supply provided

with your kit. Be sure to set the voltages going to your Game BD to 5.1 and 3.3 volts DC to assure proper operation ( Measure on Square Connector at Game BD. Yellow = 5vdc / Brown = 3.3vdc / White = Gnd )

° Step 2 You MUST USE THE COIN METER SUPPLIED WITH YOUR KIT to assure proper Coin

acceptance. A minimum 18 Gauge wire should be used from the Coin Meter 1 output line on your JAMMA Harness. The 5vdc ( Yellow ) wire found in the wiring bag of your kit MUST BE USED for the supply voltage to the meter.

Not following the directions provided herein may cause your game to malfunction. All electrical work should be performed by the site’s Serviceman or Technician.

In order to prevent an electric shock and short circuit, be sure to turn power off before performing

work or touching the interior parts of the product.

Be careful so as not to damage wirings. Damaged wiring can cause an electric shock or short circuit

accident.

Do not touch places other than those specified. Touching places not specified can cause an electric

shock or short circuit accident.

If you have any questions please contact the SEGA Service Department at the numbers given above.

www.seuservice.com

INSTALLATION INSTRUCTIONS

1) First. Remove all access panels from the game. Locate the original game Logic PCB’s & Power Supply and remove from the Cabinet by first disconnecting all harnesses from the boards. (You need only to splice in the Main Power (110v AC) into the 3-Pin Connector (GRN/WHT/BLK).)

2) Remove all existing game harnesses (we suggest using New Jamma Harnesses (NOT contained in the kit) to ensure reliability).

3) Locate the most convenient and open area of the cabinet to mount the Virtua Tennis 2 Naomi System Assembly. Make sure this area is free and clear of all cable harnesses and grounds, cable clamps, etc.

Vacuum out or clean bottom of cabinet of dirt & miscellaneous parts (e.g. screws, loose coins / tokens, etc.).

Remove all exterior decals and repair any cabinet damage. Repaint cabinet if necessary. Remove the Monitor Plexi or if your game plexi has Silk-screened artwork, you will need to strip it off.

4) Connect the JAMMA Harnesses to the JVS-JAMMA Interface Boards. Separate the wires from each other (i.e. Control Panel, Video, Speaker, Power Supply). Run the various harnesses to the part of the cabinet they go to ensuring they are dressed properly & secured to the cabinet. Locate the Volume/ Speaker/Coin Meter Cable and connect to your existing Switch Bracket or use the new one included with the kit. Note: If you are using a VGA Compatible Monitor you can run your VGA Cable directly

to the monitor or connect it to your JVS JAMMA Interface for RGB Conversion to your JAMMA Cables.

5) Remove Marquee from cabinet and cut to fit the new Virtua Tennis 2 Marquee in place.

REPLACE old Joysticks & Buttons with the NEW ones supplied in Kit.

6) First remove all Joystick and Button assemblies from the Control Panel. Remove Lexan and Control Panel Overlay. Proceed to clean surface of the Control Panel by removing all adhesive and dirt. Fill in or plug up existing button holes to set up a blank work area for your new controls.

7) Install the new Control Panel Overlay by carefully peeling off the paper backing and laying down on the panel. Smooth it out, starting in the center and working your way to the edges (removing all of the trapped air pockets). If necessary, cut the edges of the overlay excess and fold under panel.

8) Cut out the button and Joystick Holes. Install Joystick and buttons from kit into the Control Panel and tighten down. Connect all game harness wires to switches and buttons.

INSTALLATION INSTRUCTIONS

9) Proceed to place new decals on the sides of the cabinet. Locate a new monitor bezel, if needed, and

replace glass, if required (due scratches). Install Instruction Placard to the back of the Monitor Glass.

NOTE: As a precaution, disconnect the JAMMA Harness from the I/O Boards and turn power on. With a

Multi-Meter, measure the 5v and 3.3v. Adjust if necessary to 5.15v DCand 3.3vDC. Measure the +12 to

ensure the wires and voltages are in the correct position. Turn power off. Plug in the JAMMA Harness once

again to the I/O Boards. The Attract Mode should appear on the screen.

Adjust the SIZE, CONTRAST, BRIGHTNESS, and COLORS on the Monitor for optimum appearance. Adjust VERTICAL/HORIZONTAL Hold to get a stable picture, if required.

Enter DIAGNOSTICS and adjust the Volume Level, test all Buttons & Joystick for proper operation & wiring. Adjust Pricing. Coin-Up and test out a game to ensure proper play functions are as they should be.

1. HANDLING PRECAUTIONS

 To prevent electric shock or IC Board malfunctioning, be sure to turn

off the power for the cabinet when installing or removing the IC Board.

 Extraneous matter such as dust on the IC Board can cause the IC Board

to generate heat and result in a fire due to short circuit, etc. Ensure the IC Board surfaces are always kept clean.

 Use NAOMI for the cabinets compatible with JVS. Using NAOMI for

the cabinet other than those compatible with JVS can cause generation of heat and a fire.

STOP

IMPORTANT

 Be sure to connect the IC Board and connectors completely.

 For the IC Board circuit inspection, only the use of Logic Tester is

 Do not subject the IC Board to static electricity when installing the IC

 When soldering buttons, etc. to the wire harnesses, be sure to remove

the wire harnesses from the IC Board so as not to subject the IC Board to heat.

Be sure to use NAOMI together with the accessory Shield Case.

NAOMI can not be used for the cabinet incorporating a monitor or projector not corresponding to 15kHz or 31kHz.

 Concerning the display of JAMMA VIDEO STANDARD:

JAMMA VIDEO STANDARD adopted by NAOMI is referred to as JVS. As against this Standard, the conventional JAMMA STANDARD which employs 56P Edge Connectors adopted by ST-V, etc. is displayed as Old JAMMA STANDARD.

The specific Manual attached to each game sometimes displays JVS as JV STANDARD, New JAMMA STANDARD, or JAMMA 2 STANDARD AGAINST OLD JAMMA STANDARD as JAMMA STANDARD, JS, etc.

The tie-break system counts numerically (5-6 etc.), and the player, which gains seven points or more and two points or more separated, serves as a winner. In addition, two serves at a time by turns. Although this rule differs from an actual tennis rule a little, it recommends using it in convention events as a fairer judgment rule.
