Speaker 1. Remove the left cover. See Left cover on page 102. 2. Disconnect one FFC (callout 1; J2) from the fax card, remove three screws (callout 2), and remove the fax card (callout 3). CAUTION: PCAs are sensitive to electrostatic discharge (ESD). Look for the ESD reminder when removing PCAs. Always perform service work at an ESD-protected workstation or mat. If an ESD workstation or mat is not available, ground yourself by touching the sheet-metal chassis before touching an ESD-sensitive part. Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product. CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do not straighten pre-folds in the FFCs. You must make sure that all FFCs are fully seated in their connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
