Selecting the RAM TEST item on the test mode menu screen causes the on-board memory to be tested automatically. The game board is satisfac- tory if the display beside each IC No. shows GOOD.

In the TEST mode menu, selecting C.R.T. TEST allows the screen (on which the monitor is tested) to be displayed. Although the monitor adjustments have been made at the time of shipment from the factory, color deviation, etc., may occur due to the effects of geomagnetism, the location of the building’s steel frames and other game machines in the periphery. By watching the test mode screen, make judgement as to whether an adjust- ment is needed. If it is neccessary, adjust the monitor by refering to Chapter 12.
