Work through these checks
Separate power from antenna lock
BDU steady amber means startup; steady green means powered up. Antenna blinking amber means calibration, blinking green means satellite search, and steady green means satellite lock. Antenna off means ADU status unknown. These are different stages, not interchangeable green lights.
What the result means: Record each LED label, color and steady/blinking state, elapsed startup time, exact SIM warning and whether local LAN access works. Keep account and SIM identifiers private.
Read the registration light separately
Network Registered blinking green indicates packet data only; blinking amber indicates voice only; steady green indicates successful registration with full network service. Off means not registered and service unknown. Steady red reports a registration failure requiring attention. Record the actual state rather than assuming antenna lock proves voice and data.
What the result means: Record observations without resetting, changing network settings or placing chargeable test calls. Do not approach a transmitting antenna. Refer steady-red failures to qualified support.
Distinguish SIM warnings from local LAN failure
The manual treats an undetected SIM and “Wrong SIM Card” separately from LAN indication and BDU access. Record the exact SIM message for the provider; do not substitute an arbitrary SIM. For failed local access, check the existing LAN indication and installed BDU address first. A firewall or proxy may affect local access; preserve its settings for support instead of disabling protection.
What the result means: Record each LED label, color and steady/blinking state, elapsed startup time, exact SIM warning and whether local LAN access works. Keep account and SIM identifiers private.
When to stop and get help
Record observations without resetting, changing network settings or placing chargeable test calls. Do not approach a transmitting antenna. Refer steady-red failures to qualified support.
What to tell support
Record each LED label, color and steady/blinking state, elapsed startup time, exact SIM warning and whether local LAN access works. Keep account and SIM identifiers private.
