Working, but with warnings.

The manual describes continued grid feeding with a current, output or temperature limitation. Its separate red-flashing state states a warning, but does not say whether feeding continues.

What the score reflects

This mapping depends on treating the operating limitation as a warning, the manual’s date evidence, and the reason to combine references. That uncertainty remains visible.
