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.

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 without the Shield Case can cause electric wave trouble.
Be sure to use NAOMI together with the accessory Shield Case.

The monitor frequency corresponding to NAOMI is 15kHz or 31kHz.
NAOMI can not be used for the cabinet incorporating a monitor or
projector not corresponding to 15kHz or 31kHz.
1.  HANDLING PRECAUTIONS

IMPORTANT

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 contents herein described are subject to change without notice.
