Connecting LAN cable To connect this product to a network, connect the LAN cable to the LAN connector. When you use the product as a standalone device, connecting the LAN cable is not required. CAUTION: Be sure to pass the LAN cable through the groove ( ➀ ), hook the cable holder ( ➁ ), pull it out from the bottom of the rear cover ( ➂ ), and then reattach the rear cover. The cable holder prevents the cables from piling on each other. If the power cord or other cables are piled on each other, the rear cover cannot be attached.
