Family: Century MidiaBox B4 / B4+.
How it connects
Check whether the label says MidiaBox B4 or B4+: only B4+ has the terrestrial UHF input. A missing UHF channel is not automatically a satellite fault. Preserve the existing satellite list, TV input and LNBF setup before a new scan or factory reset. Century’s exact-model FAQ separates an activation banner from an LNBF-detection error and distinguishes website confirmation from activation completed at the receiver. Keep CAID/SCUA private for support. If reception freezes or LNBF detection fails, have the installation and pointing checked rather than repeatedly reactivating. The FAQ gives different quality percentages in different contexts; they are not a universal pass/fail threshold.
