Each section must reach the conditions needed for its intended food. One cold compartment or illuminated display cannot establish that the whole unit is ready.
What the observation tells you
Handling and settling requirements apply before startup, while removable packaging or fittings may need attention according to the manual. The first freezer alarm can have a documented startup meaning, but an unexplained warning still needs clarification.
A useful next step
Follow the exact first-use process and keep food elsewhere until appropriate storage is established. Do not add a large fresh freezing load immediately unless the instructions explicitly describe that procedure.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
