Work through these checks
01 · Vu+ DUO
Match the exact model, product code and manual edition. Record the existing connections, status indicators and displayed error without changing them. Preserve settings and stored data; do not reset, flash software, format storage or alter wiring as a first check. Keep account details, device identifiers and precise location private.
02 · LNB 1 In / LNB 2 In / MENU > Information / Factory Reset / DUO
Match the original HD Vu+ DUO to its 73-page English manual, not DUO², DUO LE or a DUO 4K model. The original has two integrated satellite tuners and rear LNB 1 In / LNB 2 In inputs. Preserve their installed feed configuration; a second input does not justify splitting one existing feed or changing shared cabling. If live TV works but recording fails, read the selected destination, free space and overlapping timers first. Compare whether the failure concerns one service or only simultaneous viewing and recording, without launching new recordings as a test. A visible receiver menu separates the TV display path from a blank programme; encrypted-service authorization is distinct from satellite signal. Read existing MENU > Information details before software changes, keeping private identifiers out of reports. Factory Reset erases service lists, bouquets and satellite settings; do not use it as an initial check. Do not format recordings, flash firmware or move the dish before preserving the evidence. The linked original scan is about 30.4 MB and is not fetched automatically; its historical menu examples may differ from installed software.
