Work through these checks
01 · Sea Tel DAC-2202 · antenna controller
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 · MASTER / REMOTE / INITIALIZING / Tracking / Searching / Target / Error / AGC / Status / LAT / LON / HDG / TRACK / RESET
Match the Sea Tel DAC-2202 controller and operator manual 131040 Revision D, not another DAC or an antenna package. Record the existing MASTER / REMOTE / INITIALIZING sequence and elapsed time without forcing a restart. Read Tracking, Searching, Target and Error separately; an AGC signal and tracking indication are not proof that the separate modem has network lock. If the Status error page is already accessible, preserve both its communications count and summed error code before anyone clears it. Compare existing LAT, LON and HDG readings without editing; keep location and serial numbers private. Do not press TRACK, RESET or antenna-direction arrows as a first fix: TRACK changes tracking and RESET restarts controller processors, not the antenna. Do not change targets, thresholds, heading sources, transmit-mute settings or wiring, flash or enter the radome. A qualified installer should assess repeated initialization, targeting or modem-lock faults. Historical manual examples are not firmware targets or current network-service guarantees.
