Removing the Top Cover

[Procedure]
1.
Be sure that you have the following at hand before starting the installation.
• Phillips screwdriver: Magnetic-tipped screwdriver is recommended.
• Workbench: Please carry out all work on a stable workbench or table. Spreading a cloth over the work
surface will help prevent scratching.
• Gloves: Be sure to wear gloves so that your hands are not scratched by the metal cover or other metal
parts.
2.
Switch off the A5000/A4000 power, and unplug the power cord from the wall outlet.
3.
Remove the screws holding the A5000/A4000 top cover in place.
• Set the A5000/A4000 upside down on the workbench and unscrew the 8 screws (q) along the sides of
the bottom (see illustration below). Then turn the A5000/A4000 right side up again and unscrew the 3
screws (w) along the top. Then unscrew the 5 screws (e) holding the cover to the rear panel.
