| What you see | What to do next |
|---|---|
| Record the start-up sequence | Read the ACU sequence before changing equipment. Initialization, satellite search, tracking and internal cable unwrapping are different states. |
| Distinguish unwrap from search | Preserve installed satellite, LNB, region and calibration settings. Do not lower thresholds, reset defaults or open the moving antenna. Record exact suffix, controller and receiver for qualified support. |
| Read position and GPS screens | Preserve installed satellite, LNB, region and calibration settings. Do not lower thresholds, reset defaults or open the moving antenna. Record exact suffix, controller and receiver for qualified support. |
Work through these checks
Record the start-up sequence
The manual shows INITIALIZE ACU, INITIALIZE ANTENNA, SEARCH, then TRACKING. Note where it remains and which satellite name appears. The illustrated DTV101 name is a historical example, not a current service-selection instruction.
What the result means: Read the ACU sequence before changing equipment. Initialization, satellite search, tracking and internal cable unwrapping are different states.
Distinguish unwrap from search
ANTENNA IS UNWRAPING describes internal cable winding/unwinding. Watch whether tracking returns without interrupting the mechanism. If interruption persists, record duration and receiver symptoms instead of repeatedly changing target satellites.
What the result means: Preserve installed satellite, LNB, region and calibration settings. Do not lower thresholds, reset defaults or open the moving antenna. Record exact suffix, controller and receiver for qualified support.
Read position and GPS screens
On the documented normal-mode ACU, the center soft key cycles through antenna position/signal and GPS information before returning to tracking. Record the displayed values for support. Stay out of Setup; a tracking display alone does not confirm receiver authorization or channel reception.
What the result means: Preserve installed satellite, LNB, region and calibration settings. Do not lower thresholds, reset defaults or open the moving antenna. Record exact suffix, controller and receiver for qualified support.
When to stop and get help
Preserve installed satellite, LNB, region and calibration settings. Do not lower thresholds, reset defaults or open the moving antenna. Record exact suffix, controller and receiver for qualified support.
What to tell support
Preserve installed satellite, LNB, region and calibration settings. Do not lower thresholds, reset defaults or open the moving antenna. Record exact suffix, controller and receiver for qualified support.
Common questions
Why does the manual show i3 screen examples?
Page 29 explicitly says the documented operation method is shared by i3, i3L, i4 and i4P and uses i3 as the example. This statement applies to this manual revision; it does not establish compatibility with i4 Inland or later hardware.
