POWER SUPPLY
Be sure voltage switch is set to 115V (110V to 120V respectively) before installing the new
power supply in the computer case, regardless of what country the game is in.
Unlock and remove the backglass. Grasp the case from the front and slide it toward you. Let it hang
down in front of the monitor. Unplug the three cables on the left side and the one cable in the front of
the case. Lift the rear of the case and pull it out of the backbox. Unplug the IEC cord from the rear of
the computer case.
Remove the four outer screws surrounding the power supply that secure it to the case (see the
diagram below). Slide the metal clip to the right and lift cover off of the computer case. Unplug the
cable harnesses leading from the power supply; one plug is going to one connector on the power
amp and two plugs are going to one connector on the motherboard. Lift the power supply out of the
computer case.

MEMORY
The ROM chips contain the computer operating instructions. Memory devices are very sensitive to
static charges. Use grounding precautions when handling these parts.
To remove a ROM from its socket, carefully note its position and then lift it using a chip extraction
tool. To reinstall a ROM place it over its socket so that the notch in the chip lines up with the
silkscreen on the board, and press down firmly to seat. Do not force the ROM into the socket. Do not
bend the pins under the ROM.
CAUTION
Use wrist straps, conductive mats or other methods of safely discharging static electricity. Hold all
chips by their packages and not by the metal pins. Extractor and insertion tools are recommended to
avoid bent or broken pins caused by excessive force.

BATTERY
Note the position of the battery. Gently lift the contact arm to release tension. Do not bend the arm.
Slide the battery out of it holder. To reinstall the battery, orient the cell near the holder and slide it
under the contact arm. Do not force the battery into the holder.
CAUTION
Danger of explosion if battery is incorrectly replaced. Replace with only the same or equivalent type
recommended by manufacturer. Do not attempt to recharge these batteries. Avoid direct shorts
across terminals or from terminals to ground. Dispose of batteries according to manufacturer's
instructions.
