When this guide applies

Exact Marantz STEREO 70s. Both source records already exist; no new enrollment, forced reset or record replacement. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Bluetooth. Symptom: Switching between devices isn’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.

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.
