Work through these checks
01 · Kathrein UFS 923 si / sw · 250 GB / 1 TB
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 / LOOP OUT / Tuner-Konfiguration / Durchschleifen / Netzwerkeinstellungen / DHCP
Match UFS 923 si/sw and the original Part 2 cover: software scope from 1.00, with 250 GB or 1 TB versions. Do not substitute a later 500 GB edition. Distinguish LNB 1 IN and LNB 2 IN from LOOP OUT. Read Tuner-Konfiguration without changing it; Durchschleifen limits tuner 2 to the receiving plane selected by tuner 1. Record which channels fail during a recording. In Netzwerkeinstellungen, note the existing DHCP state; a network fault does not prove satellite reception failure or that old portal services still work. Preserve recordings, channel lists and shared single-cable assignments; do not reset, format, flash or rewire first.
