When this guide applies

Denon AVR-X3900H (NA) / AVR-X2900H (EU). New phone/player source; current listening can stop. Exact AVC-X4800H controls already documented in its existing guide; receiver return output is MONITOR 1 for AVC-X4800H and TV 1 for the two AVR models.

Connection scope: Bluetooth. Symptom: My devices won’t pair or reconnect.

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 step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

step-0

Are the supplied wireless antennas already correctly fitted and the receiver on?

Do not change rear connectors or use another antenna socket in this flow.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-1

Is there room below eight saved sources, or is replacing the oldest registered source acceptable?

Unknown history or unwanted replacement stops without clearing any saved device.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-2

May active listening stop for new-source registration at low media levels?

Pairing changes the active source connection.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-3

Hold Bluetooth on the supplied receiver remote for at least 3 seconds

Use the Bluetooth key, not a power/reset combination.

Look for: Perform only the stated operation, then confirm it was possible.

step-4

Choose this exact receiver from the nearby source Bluetooth list

Use the actual receiver identity and the source documented pairing control.

Look for: Perform only the stated operation, then confirm it was possible.

step-5

Does the source confirm the intended receiver connection?

A discovered name alone is not a playback result.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

Possible result

Checks completed — report the actual result

Completion does not automatically mean the problem is solved. Report what actually happened; no physical test or measured repair is claimed.

steps completed

Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

    Possible result

    Stop at the unconfirmed condition

    A required setup or response was not confirmed. Retain the actual observation and consult the exact source/partner manual or official support. Do not escalate to a reset, update installation, internal repair or unsafe wiring change.

    next support

    Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.

      Possible result

      A required fact is unknown

      Confirm the actual model, connection, partner capability and state before continuing. Do not guess a menu, interrupt an installation or modify a live source by trial and error.

      insufficient data

      Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
