Why this decision matters
A powered-on indicator does not prove that the detection, recording, release or reporting outcome still works.
Work through the actual task
- Review the authorised app login, device permissions and supported notification settings.
- Test the intended event with the replacement phone locked.
- Assign each follow-up to a person and book qualified service for internal electrical work.
Worked example
A phone replacement stops alert notifications. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A confirmed notification result on the user's current device.
Limits and follow-up
Avoid exposing recorder ports directly to the internet. Discuss supported secure access options and keep the device software maintained.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
