SECTION 2
Disassembly method
2.1 Main body
2.1.1 How to remove a top cover (See Figure 1 and 2.)
(1) Screw A attaches a top cover to the main body. Remove
the two screws A from the both sides of the main body.
(2) Raise the top cover in a direction that the arrow indicates.
And the top cover will be removed.
