HOW TO USE
Define the task and essential requirements before testing. Repeat under comparable conditions and on another occasion. Use metres and hours where applicable. Keep observations separate from projections. Without a trustworthy reference, report repeatability rather than accuracy.

RECORD
1. Task; terrain; duration; essential map/recording functions:
   ____________________________________________________________

2. Model/software; satellite mode; recording interval; antenna orientation:
   ____________________________________________________________

3. Place/time; sky view; temperature; time since startup:
   ____________________________________________________________

4. Reference coordinate, source, datum and units (or unknown):
   ____________________________________________________________

5. Repeated coordinates; observation times; fix status:
   ____________________________________________________________

6. Mean/spread; reference agreement only if justified:
   ____________________________________________________________

7. Power start/end (%); elapsed hours; screen/wireless settings:
   ____________________________________________________________

8. Observed rate (percentage points/hour); projection assumptions:
   ____________________________________________________________

9. Readability/control tasks; condition; exact environmental rating source:
   ____________________________________________________________

10. Map/update/export support evidence:
   ____________________________________________________________

11. Decision: meets task / more evidence / essential failure:
   ____________________________________________________________

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.
