5-1 PCB start-up check (self test)
5 PCB settings
When the power switch is turned ON after installation of machine, the performance of
game Printed Circuit Boards (PCB) is checked automatically and the result is
displayed on the screen. If the power is not turned ON, make sure that the main
power switch and sub-power switch are both at the ON position. (See pages 24 and 25)
•Be sure to check the PCB unit (self test) before using the machine.
•When the machine has been set up or moved to another place, turn ON
the power switch and press the demagnetizing button on the service panel
to demagnetize the monitor. If the monitor is still magnetized, the gun
unit may respond well or the target points may get out of position.
•When the machine has been set up or the PCB unit or the gun unit has
been repaired or replaced, be sure to position the target points, referring
to “CALIBRATION” on page 22.
•When the settings have been brought back to the factory ones, be sure to
position the target points, referring to “CALIBRATION” on page 22.
•If an abnormality persists or the machine does not operate properly,
immediately turn OFF the main power switch, unplug the power cord from
the receptacle and contact your nearest dealer.
