Eventide ARGUS 3000 - ON;OFF Switch Assembly in 3000 and 5000

4. The rear cover is attached to the unit housing with three flat-head screws. Remove these screws.
CAUTION
Do not remove the red-marked screw on the top cover at this time. This screw does not secure the
rear cover. This screw is not as long as the others because there is not as much clearance at this
location. If you remove this screw, be sure to put the correct screw back in this location so as not
to damage the unit.
5. The rear cover is connected to the CPU board. Slowly pull the rear cover out of the unit housing
until the boards are exposed approximately 1-1/2 inches.
6. A ribbon cable connects the solder side of the CPU board to the mother board. Disengage this
connector and slide the CPU board completely out of the unit's housing.
7. Remove the screws securing the bottom cover to the front bezel, and remove the bottom cover.
8. At this point the ON/OFF switch can be seen. (Refer to Figure 13.) Note its orientation in relation
to the top cover and the mother board. Disconnect the ON/OFF switch assembly from the mother
board by pulling up on the connector. ^
