4. Set the power on/off switch to the on position.
Within 30 seconds the TV monitor should
display a picture.
5. Slowly open the rear access panel. The TV
monitor picture should disappear when the
panel is opened approximately 2.5cm (1 inch).
Close and lock the access panel and repeat this
step with the coin door.
6. If the results of step 5 are satisfactory, the inter
lock switches are operating properly. If the TV
monitor doesn’t go off as described, check to
see if the corresponding interlock switch is
broken from its mounting or stuck in the on
position.
3. Game Fuses
For continued protection of your game, as well as
for the safety of the players, fuses must be replaced
only with fuses with identical ratings. These ratings
are shown in Figure 18. See the Schematic Drawing
Package for fuse functions.
Information on the TV monitor fuses is contained
in the TV monitor manual that is supplied with this
game.
D. Self-Test Procedure
This game will test itself and provide data to
demonstrate that the game’s circuitry and controls
are operating properly. The data is provided on the
TV monitor and the game speaker; no additional
equipment is necessary.
Part of the self-test procedure includes a display
of the operator-selectable game options. Therefore,
we suggest you run the self-test procedure anytime
you need to change the game’s options.
To run the self-test, follow the instructions out
lined in Figure 6.
