NOTICE: When installing this module, ensure that the antenna cables are not under the card. Place the antenna cables in the holder next to the
module. Installing the module on top of these antenna cables may cause damage to your computer.
NOTICE: The connectors are keyed to ensure correct insertion. If you feel resistance, check the connectors on the module and on the system
board, and realign the module.
NOTICE: An FCM can be installed in the WWAN/FCM card connector or the WPAN/UWB/FCM card connector. Use whichever card connector is
available. If both are available, use the WWAN/FCM card connector, which is easier to access.
