KEF LSX II: inspect Bluetooth discovery on the Primary speaker

step-0

Have these speakers already completed local-network setup?

The manual requires initial network setup before Bluetooth use; do not bypass it with another model procedure.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

• If Yes / this check is completed → Can an existing Bluetooth connection safely be interrupted?
• If No / this cannot be confirmed → Keep the observation for manufacturer support
• If I do not know / cannot check → A required observation is unknown

step-1

Can an existing Bluetooth connection safely be interrupted?

The rear pairing control disconnects an active Bluetooth source but keeps its saved record.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

• If Yes / this check is completed → Select Bluetooth mode
• If No / this cannot be confirmed → Keep the observation for manufacturer support
• If I do not know / cannot check → A required observation is unknown

step-2

Select Bluetooth mode

Choose Bluetooth in KEF Connect or with the remote Source control.

Look for: Perform only the stated check, then confirm whether it could be completed.

• If Yes / this check is completed → Is the Primary indicator pulsing blue?
• If No / this cannot be confirmed → Keep the observation for manufacturer support
• If I do not know / cannot check → A required observation is unknown

step-3

Is the Primary indicator pulsing blue?

A pulsing-blue discovery state does not need a disconnect press. Choose No only if a current Bluetooth connection is confirmed; otherwise choose unknown.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

• If Yes — discovery is active → Select the exact KEF model in source Bluetooth
• If No — an existing connection is confirmed → Briefly press the rear Bluetooth-pair control
• If I do not know / cannot check → A required observation is unknown

step-4

Briefly press the rear Bluetooth-pair control

Use B once to disconnect the confirmed old connection and enter discovery; do not press Reset.

Look for: Perform only the stated check, then confirm whether it could be completed.

• If Yes / this check is completed → Select the exact KEF model in source Bluetooth
• If No / this cannot be confirmed → Keep the observation for manufacturer support

step-5

Select the exact KEF model in source Bluetooth

Choose KEF LSX II or the known name assigned to your pair.

Look for: Perform only the stated check, then confirm whether it could be completed.

• If Yes / this check is completed → Does the connected indication appear?
• If No / this cannot be confirmed → Keep the observation for manufacturer support
• If I do not know / cannot check → A required observation is unknown

step-6

Does the connected indication appear?

Confirm the source connection and steady Bluetooth indication before assuming music is routed correctly.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

• If Yes / this check is completed → Checks completed — report your outcome
• If No / this cannot be confirmed → Keep the observation for manufacturer support

Possible result

Checks completed — report your outcome

Completion does not automatically mean solved. Report what actually happened: solved, partly helped, did not help or could not follow. No Audio Review physical test is claimed.

steps completed

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

Possible result

Keep the observation for manufacturer support

These steps did not establish a working setup. Keep the exact model, source, software and last observed response for support. No hardware or firmware defect is diagnosed.

next support

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

Possible result

A required observation is unknown

Confirm the exact model and linked instructions before continuing. Do not guess the state of a control, connection or update.

insufficient data
