3. Fix the CPU by rotating clockwise the cam by 90 degrees with a flat-blade

screwdriver.

4. If there is already silicon grease on the CPU and cooling fin, clean it with a cloth.

Using a special applicator, apply quarter of scale (0.25ml) of silicon grease evenly on

the CPU chip.

NOTE: If silicon grease has already been applied to the CPU or cooling fin, wipe clean

with a cloth and apply new silicon grease. The computer will not operate correctly if the

CPU is not firmly in contact with the cooling fin.
