10. EXPLANATION OF TEST AND DATA DISPLAY
By operating the switch unit, periodically perform the tests and data check. When installing the
machine initially or collecting cash, or when the machine does not function correctly, perform
checking in accordance with the explanations given in this section.
The following shows tests and modes that should be utilized as applicable.
This product's basic system consists of the NAOMI 2 GD-ROM game board. The system
enables you to play several games one after the other just by changing a GD-ROM disc and key
chip.
The product supports, therefore, the following 2 test modes:
(1) System test mode for an automatic self-diagnostic test (generally used by every product that
contains the basic system) and a coin assignment (specifically used by this product) and
(2) Game test mode for testing the input/output control devices and setting the difficulty level
(specifically used by this product).
This manual does not cover the automatic self-diagnostic test. For more information about the
system test mode, see the attached NAOMI NETWORK SYSTEM Service Manual.
