INTERPRETATION
Record unknown or untested items explicitly. A completed checklist documents the observations made; it does not certify equipment or guarantee navigation performance. Recheck unresolved essential functions before relying on the configuration. Keep original data and the source/version context with this record.

SOURCE CONTEXT
The guide explains how each source applies. Manufacturer instructions are model-specific; historical and operational records carry their own dates.
