Fuse
The MDL-7 fuse is located in the left end of the cabinet, near the display
controller (refer to Figure 41).
To replace the fuse, push and turn the fuse cap, insert the new fuse into the
cap and reattach.
4.4 Controller Address and Test Mode
The controller has a set of “DIP” switches on the side of the controller as shown in Figure 35. These
switches set the hardware address. When replacing a controller board, be sure to set the DIP switches
in the same address configuration as the defective controller.
Note: A test mode can be activated by setting the DIP switches to address 0 (turn all the switches to
OFF by flipping them toward the printed switch numbers). The display’s power must be downed, and
then reconnected to run the test mode.
