SPECIAL NOTICE FOR

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.
