Why this decision matters
A feature list cannot show whether the intended person can reach, read, hear or complete the actual control task.
Work through the actual task
- Arrange a safe photo or help recording the visible indication.
- Request the explanation and operating steps in a usable format.
- Have the intended users try the proposed control method before committing to a final position.
Worked example
A user cannot read the small fault message clearly. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A clear user-facing account of the fault and restored routine.
Limits and follow-up
Do not open mains powered equipment or defeat tamper switches. Arrange a qualified service visit when a fault needs internal inspection.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
