When this guide applies

Exact Naim Mu-so 2nd Generation. Original supplied handset; only a positively identified removable shipping tab, not battery service. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Device controls / power only. Symptom: Buttons, touch controls or wear detection aren’t working.

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.
