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.
°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 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.
SPECIAL NOTICE FOR
ALL SEGA NAOMI KITS
PROBLEM:
SOLUTION:
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.

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).)
) 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 Switc 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 +1 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.
