Work through these checks
01 · SEFRAM 788x family
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 · 788x / Check Sat / Sync ? / NIT / MER / LKM / BERo / PER / Factory recovery
Match 788x to the SEFRAM original M7885001A/03, manual 3.0, March 2021, 153 pages; group 7880/7881/7882/7884/7885 and their 4K editions as one family, without assuming every model has IPTV, optical input or other options. Record existing standard, list and readings without changing them. In Check Sat, identification requires all four configured transponders synchronized; red means not all four lock, orange means all lock with average quality, and green means good quality. Changed transponder data can explain incomplete identification; preserve the list. An existing NIT name depends on broadcaster data and may be wrong. Sync ? means absent or unlocked signal, not a failed meter. Separately, error-rate bars use orange for BERo above 10^-4 without lost packets, and red for lost packets measured by PER; do not confuse these with Check Sat criteria. Keep RF level separate from MER quality and LKM margin. Record remote-power warnings: cable voltage may already exist or current may exceed the limit; safely isolate feeds before accessible cable inspection, never repeatedly reconnect live. Factory recovery erases setup library and measurement lists. No active scans, motor/dish tests, voltage/configuration changes, resets, updates, calibration, fuse or battery work; never interrupt a known update. Protect site/network identifiers; no current service compatibility promised. This SEFRAM-authored original is distributor-hosted by Vector Technologies, not a verified manufacturer download endpoint.
