In the test mode, selecting CRT test allows the projector test screen to be displayed. Although the projector adjustments have been made at the time of shipment from the factory, color deviation may occur due to geomagnetic effects, steel in the building frame, or other game machines. By watching the test mode screen, make judgment as to whether an adjustment is needed. If an adjustment is necessary, refer to the appropriate section of this manual.
In the output test mode, carry out the lamp test to ensure
that each lamp lights up properly.
Each of the above tests should be performed during the regular monthly maintenance inspection.
