When this guide applies

Exact DALI IO-8 is charged and switched on in an active listening mode. This is not passive, battery-free mini-jack operation. Use a quiet safe location and a comfortable level.

Connection scope: Device controls / power only. Symptom: Noise cancellation or listening modes 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.

Checks and possible outcomes

Identify the correct control

Find the ANC button on the edge of the right ear cup. It is separate from the centre media button and from the Hi-Fi/Bass sound-mode button.

Look for: The dedicated ANC control is identified.

Compare the documented mode cycle

Use individual short presses to move through noise cancellation, Transparency and Off. Do not treat Transparency, which admits outside sound, as a failed ANC setting.

Look for: The actual listening-mode changes are observed.

Keep the intended mode

Choose ANC if reduction of ordinary surrounding noise is wanted, or restore the previous preference. This comparison does not promise silence or diagnose a microphone fault.

Look for: Record whether the intended mode is selected and its effect can be heard.
