   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 2 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.
   Be sure to connect the IC Board and connectors completely.  Insufficient 
insertion can damage IC Board, etc.
   For the IC Board circuit inspection, only the use of Logic Tester is permitted.
The use of ordinary testers is not permitted as these can damage the IC Board.
   Do not subject the IC Board to static electricity when installing the IC Board 
in the cabinet or when connecting wire harness connectors to the IC Board.
   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.
   Using NAOMI 2 without the Shield Case can cause electric wave trouble.  Be 
sure to use NAOMI 2 together with the accessory Shield Case.
   The monitor frequency corresponding to NAOMI 2 is 15 kHz or 31 kHz.
NAOMI 2 can not be used for the cabinet incorporating a monitor or projector 
not corresponding to 15 kHz or 31 kHz.
1.  HANDLING PRECAUTIONS
 Concerning the display of JAMMA VIDEO STANDARD:
    JAMMA VIDEO STANDARD adopted by NAOMI 2 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 contents herein described are subject to change without notice.

3 - 1 OUTLINE OF THE GAME
 You, as a martial art fighter, play in a tournament.
 For one-person match, you operate a playing character to fight against an opponent computer-
operated character (CPU).
 For person-vs-person match, two players operate each playing character to fight against each 
other.
 The playing characters covers 15 selectable regular characters and 1 boss character .
3 - 2 PLAYING PROCEDURE
 Total 15 characters are available. Out of them you select one character to start the game.
 At each stage you play a match against a computer-operated character.
 Winning a match
•  Each match consists of multiple rounds. You win a match when the number of your gained 
rounds reaches a preset value.
•  When you win a match at any stage, you can proceed to a next stage and play a match against 
a new computer-operated character.
 Gaining a round
    You can gain a round when either of the following events occurs.
•  You successfully reduce the opponent's energy to 0 (zero).
•  Your energy remains much more than the opponent's energy when the limit time has become 
0 (zero).
•  You turn the opponent out of the ring.
When you and the opponent have drawn (that is, at the end of a round, both have a same level of 
energy or have knocked each other at the same time), both can gain the round exceptionally.
When you and the opponent have drawn under a sudden death state (that is, the number of the 
gained rounds is equal to each other and either can win the match by obtaining one more round), 
either with more energy becomes a winner of the match.
 When the GAME becomes OVER
    The game is over when either of the following events occurs.
•  You lose a match against a computer-operated character.
•  You finish all the 11 stages: 10 stages, each with a regular computer-operated character, and 1 
stage with a boss computer-operated character.
 Continuing the game
    You can continue the game as follows.
•  When you lose a match, the CONTINUE screen appears.
•  Insert the credit coins before the limit time is counted down to 0 (zero) on the CONTINUE 
screen, and press the start button. Then, you can continue the game (or resume the first round 
of the stage where you lost a match).

3 - 6 SPECIAL OPERATIONS OF THE CONTROLS
Dodging/Attacking
Immediately after surely dodging by a lever operation, you attack an opponent. Thus you can use 
the combination of dodging/attacking skills. 
Lever in an upper position instantly + P + K + G: Dodging away from you and attacking
Lever in a lower position instantly + P + K + G: Dodging toward you and attacking
Recovery (Ukemi = safe ways of falling down)
The ukemi enables you to regain your balance just when landing and to immediately attack an 
opponent. This skill lessens damage to you. Thus you can escape from the crunch and rather earn 
a chance to counterattack. You may be just downed or use the ukemi, whichever is tactically 
desirable in each situation. 
P + K + G immediately before you are downed: Ukemi
Charge Attack (attacking with the accumulated energy)
Using the energy accumulated for a little time, you can destroy an opponent's defenses. This 
high-risk, high-return skill enhances your tactical capabilities. Special commands, one each with 
a character, are available to activate this function. 
Fighting by the walls
•  You may damage and destroy the walls. Thereby you can change the state of the ring as 
tactically required.
•  The opponent may falter when you throw him/her against the walls. This enables you to use 
the combination (Combo) skills.

3 - 7 PERSON-VS-PERSON (VS) MATCHS
•  A new player may join you in playing the GAME or selecting a character. As a result the 
system suspends the current one-person match against a computer-operated character and 
starts a person-vs-person match.
•  The new player must insert the credit coins before joining.
•  After playing the person-vs-person match only the winner can continue to play the suspended 
match: one-person match against a computer-operated character. He/she resumes the first 
round of the suspended match.
PERSON-VS-PERSON (VS) MATCHS • CHARACTER SELECT SCREEN
•  When you have set the STAGE item to RANDOM on the GAME ASSIGNMENTS screen, 
the built-in computer (CPU) randomly selects a stage.
•  When you have set the STAGE item to SELECTIVE on the GAME ASSIGNMENTS 
screen, the newly joined player selects a stage. (For more information see the chapter 4, B, b. 
"GAME ASSIGNMENTS.") To select, he/she places the lever in an upper, lower, left, or right 
position to migrate from stage to stage, and presses either of the punch, kick, and defense 
buttons.
