Installing the Cooling fin/CPU
The following describes the procedure for installing the cooling fin/CPU (See Figure 4-11 to
4-16).
1. Check that the mark on the cam is in the unlocking position.
2. Attach the CPU to the correct position in the CPU socket.
CAUTION: Place the CPU in such direction as shown below. (Pay attention to the
position of the triangle mark on the CPU.)
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.
