Handling PC Boards
Some steps in this upgrade involve handling printed circuit boards. Many components
on the PC boards are very sensitive to static electricity. These components can be
destroyed if static charge on your body discharges through the component. You do
not even have to touch the component to damage it. Before touching the components
or the printed circuit boards, ground yourself by rubbing the frame of the unit with
each hand or wearing an earthing strap.
Installation
1. Remove mains power from the CP650 by unplugging the rear panel power cord.
2. Open the setup control panel access door.
3. Remove the front-panel mounting screw located in the upper right-hand corner of
the setup control panel, and carefully pull the front panel toward you to remove it.
4. Remove the seven sub-
panel mounting screws and
carefully pull the subpanel
toward you to remove it.
Be sure to support the
panel while you perform
the next step.
5. Unplug the two ribbon
cables connected to the
internal circuit boards.
6. Remove the upper circuit
board (Cat. No. 774) using
the left and right card
ejectors. Place the board on
a flat surface (for example,
on a platter disk). The
board should be oriented
with the card ejectors close
to you.
