2 Handling PC Boards
This upgrade involves handling printed circuit boards. Many components are very
sensitive to static electricity and 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 on the PC boards, ground yourself by
rubbing the frame of the unit with each hand or wearing an earthing strap.
3 Installation Steps
1. Remove mains power from the CP650 by unplugging the rear-panel power cord.
2. Open the setup control panel access door.
