TELE System TS4020 T2S2HEVC · 21005336 · Rev.00 · 2021-08-30. Exact manual and safe first checks.
How it connects
TS4020 code 21005336 has separate SAT IN and RF IN sockets. Its DTT and SAT buttons open different channel lists; TV/RADIO changes the service type. A clock with red LED is standby, while green with a channel number is on. The pictured remote REC button has no assigned function; do not diagnose missing recording as a disk failure. Match the model, product code and manual edition on this page. Photograph existing connections without changing them. First separate TV input and standby problems from missing satellite reception. Preserve the channel list and antenna settings; do not factory-reset, flash software, rescan or rewire as a first check.
