Model: This guide is limited to the tivùsat procedure PDF specifically named for HUMAX Tivumax LT HD-3600S2. Its pages say Humax Tivùmax without a printed revision/date identified. Match the installed model and menu; do not apply it to HD-3601S2 or another similarly named receiver. This is a procedural source, not a complete installation manual or a current service/card-compatibility approval.
How it connects
Record System Information and the existing signal strength/quality before requesting service. The provider says reset removes stored channels and personal settings while retaining the last installed software, so it cannot simply be treated as a way to undo that software. Keep the model label, displayed system information, affected and working channels, selected satellite/frequency, both signal values, time and any recent change. State clearly whether the receiver is currently updating. Protect smart-card/account identifiers and the existing channel/configuration records when sharing evidence.
