These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Identify the intercom and check its wiring
What they doAn intercom installer identifies the make, model and whether the handset is digital or analog, checks connections against the app diagram and looks for an external chime.
They must show youthe identified model, wiring against the diagram and the call detected in the test.
In writingthe intercom model, connections corrected and whether an external chime exists.
Configure the external chime with Ring Customer Support
What they doIf the handset is analog and there is no existing wire in the A-6 or C-6 terminal, Ring Customer Support guides the extra configuration for the external chime.
They must show youthe configuration steps applied.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Intercom make and model in the app
- Who:
- you, in the Ring app.
- How:
- check the make and model chosen during setup match your intercom.
- Result that matters:
- whether the selected model is correct.
- If the model was different:
- correct it and rerun the test; it is a common cause of P16-160.
- If the model is correct:
- check the wiring and when you press the button.
- Evidence to keep:
- photo of the intercom label and screenshot of the chosen model.

Pressing the call button at the right moment
- Who:
- you and someone at the lobby panel.
- How:
- press the lobby panel call button exactly when the app asks and wait five seconds at each stage, as Ring advises.
- Result that matters:
- whether the call is detected with a timely press.
- If it is detected:
- the timing was the issue.
- If it isn't:
- check the wiring and, if analog, the A-6 or C-6 terminal.
- Evidence to keep:
- note of who pressed, when and what the app showed.

Wiring and the A-6 or C-6 terminal
- Who:
- you, at your own flat's handset.
- How:
- compare the wires with the diagram and gently tug each one. On analog handsets, see whether the terminal where Ring's A-6 or C-6 wire goes already had a wire.
- Result that matters:
- whether wiring matches and whether that terminal had an existing wire.
- If there was no existing wire in that terminal:
- there may be an external chime; Ring asks you to contact Customer Support.
- If everything matches and the code remains:
- remove Ring Intercom from the app and set it up again from the beginning, waiting five seconds at each stage and pressing the doorbell button several times in the last stage.
- Evidence to keep:
- photo of the A-6 or C-6 terminal and the full wiring.

What it means
Ring explains that P16-160 appears when Ring Intercom cannot detect an incoming call during Testing Mode, on digital or analog handsets. For digital handsets it blames an incorrect intercom model selection in the app, a wiring issue or not pressing the call button at the right time. For analog handsets, incorrect model selection, wiring, or an external chime that needs additional configuration. The code does not prove the handset or the Ring Intercom is faulty.
