Replacing the Top Cover
• When replacing the top cover be sure that you do not get cables caught between the cover and main
unit, or apply unnecessary force to the cables or internal circuitry.
[Procedure]
1.
Holding both sides of the top cover with both hands, carefully slide the cover back to its
original position.
2.
Use the original screws to re-attach the top cover.
• Use a “plus” screwdriver to replace the five screws
q
in the rear panel. Tighten the central screw first
(“
★
” in the illustration below).
• Then, facing the front of the unit attach the three screws across the top
w
while applying pressure to the
center of the rear-panel side of the top panel to hold it in place.
• Finally, turn the unit upside down and attach the 8 bottom-panel screws
e
.
• Do not use screws other than those removed in step 3 on page 232 (
q
,
w
,
e
, are the same screws). Other
screws can damage the unit.
