Maintenance

Perform regular maintenance by following the procedures below.

  1. Remove the earbud tip.

    Hold the headset unit and twist the earbud tip while rotating it to pull it out.

    Do not pinch the end of the earbud tip when removing it.

  2. Clean the headset.

    Cleaning the headset units

    Dust and dirt on the exterior of the headset can be wiped off with pure water type wet wipes. Do not use wet wipes containing alcohol, thinner, benzene, etc. as they may damage the finish on the surface of the headset or cause other damages.

    Use a soft dry cloth to wipe off any water that gets on the headset units.

    Do not allow the headset to remain with water droplets attached in a cold environment as the water may freeze.

    Cleaning the charging ports

    If foreign matter or moisture, such as sweat, etc., is left on the ports (A) of the headset or the ports (B) of the charging case, charging port corrosion may occur and prevent charging.

    When you have finished using the headset, make sure to gently clean the charging ports with a soft dry cloth or cotton swab.

    When the headset cannot be charged, it may help to try thoroughly cleaning the charging ports.

    Note

    • Do not use an air duster, etc. to remove dust, etc.
      Dust and other debris may enter the sound output holes and cause malfunction.

    Cleaning of the sound output holes

    Use a cloth that has been moistened with water and wrung out tightly to remove any dirt, including earwax, from the sound output hole (C) or groove (D) on the headset unit.

    Remove the dirt so that it does not push into the headset unit deeply.

    Cleaning the holes of the charging case

    Clean the holes (E) where the earbud tips fit with a cotton swab, etc.

    Drying the headset

    After cleaning is complete, leave the headset to dry thoroughly at room temperature.

  3. Attach the earbud tip.

    Push the earbud tip firmly onto the sound conduit (sound output tube) on the headset so that the earbud tip covers the inner end of the sound conduit. Do not attach the earbud tip in a loose or skewed manner.

    If the earbud tip is not completely attached, the earbud tip may be removed from the headset, reducing the sound quality and wearability.

  4. Set the headset in the charging case.

    After maintenance as well as after cleaning and drying the headset, be sure to set the headset units in the charging case.

    Be sure to close the charging case lid.
