When this guide applies

Exact Yamaha R-N800A. Normal settings only, not a YPAO measurement or calibration. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Device controls / power only. Symptom: An option or codec is missing.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
