Repair Procedures; Opening The Unit - Alesis Andromeda A6 Service Manual

4.0 Repair Procedures

This section contains repair procedures for the A6.

4.1 Opening the Unit

Before opening the unit, make sure you and your work area are properly grounded!!!! The A6
circuitry (especially the analog ASICs) is extremely sensitive to static electricity!!!!
4.11 Opening the Unit
° Unscrew the screws on the bottom of the unit, but do not unscrew the 12 screws directly
under the Fatar keyboard. These hold the keys in place.
° Unscrew the 5 screws on the rear panel of the unit.
° Grab the endcaps and gently lift the top panel away from the bottom panel, rear end first.
Be careful not to damage the rear end of the plastic endcaps. That section is fragile.
° When the top panel is free, tilt it backwards and place it behind the bottom panel.
4.12 While the Unit is Open
° Implement outstanding ECNs and test the unit for correct implementation.
° Hot-glue any connectors you may have disconnected.
° Load the latest OS code into the unit.
° Follow the QC test procedure outlined in the previous section of this manual.
4.13 Closing the Unit
° If you had to unscrew any screws that go into plastic, apply Loc-Tite when re-screwing
them.
° Replace the top panel by aligning the front end first, then carefully lowering the back
end.
° Make sure the metal bracket right beneath the Ribbon Controller does not pinch the
ribbon cables coming from the keyboard.
° Re-screw all of the screws.
