(2) Replacing the Main PC Board
z
To avoid electric shock, accidents or injuries to yourself or other people, or damage to the electronic
circuits, be sure to turn off the power switch before starting work.

PC boards are sensitive to static electricity. If a person handles a PC board while
charged with static electricity, the parts on the PC board may be damaged. Before
handling a PC board, discharge the static electricity from your body; for example,
by touching the surface of grounded metal.
Turn off the power switch. (See “7-6-1 Turning the Power Switch On” on page 39.)
Remove the two wing bolts (M5 x 16), disconnect the 15 connectors, and pull out the PCB base.
