1. HANDLING PRECAUTIONS
1
@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.
WARNING @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.
@Keep the IC board well cooled.
The NAOMI 2board
case
and GD-ROM drive
are
provided with Heat
Exhaust Fan. Do not block the air outlets of these fans. Also do not
place anything closely to the NAOMI 2board
case
and GD-ROM drive.
Failure to observe these instructions may cause an overheating and
fire.
Gror Be sure to connect the IC Board and connectors completely .
Insufficient insertion can damage IC Board, etc.
IMPORTANT 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 2without the Shield Case
can
cause
electric
wave
trouble. Be sure to use NAOMI 2together with the accessory Shield
Case.
The monitor frequency corresponding to NAOMI 2is 15kHz
or
31kHz.
NAOMI 2 can not be used for the cabinet incorporating a monitor or
projector not corresponding to 15kHz
