Reassembling Notes
• Once removed, the insulation sheet will become unusable and a new one should have to
be put back in. When attaching it to the bottom plate, align the rear edge with that of the
bottom plate and fit the positioning hole with that provided in the bottom plate, as shown
above.
• Before putting the bottom plate back into place, make sure that the power supply PCB is
completely fitted in the resin PCB supports without any gap.
After installing the bottom plate, check that resin PCB support "b" of the main frame ap-
pears from the checking hole "a" provided in the bottom plate and that the bottom plate is
fitted in the main frame without any gap.
If the power supply PCB comes into contact with the bottom plate, a short circuit may oc-
cur.
