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 IR sensors

    If the IR sensors (A) are dirty, wearing of the headset may not be detected and the headset may not work properly.

    Wipe off any dirt on the IR sensors (A) with a soft dry cloth, etc.

    Cleaning the charging ports

    If foreign matter or moisture, such as sweat, etc., is left on the ports (B) of the headset or the ports (C) 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.

    Drying the headset

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

    Note

    • When drying the headset, if the IR sensors touch the table, the headset will be considered worn and the rechargeable battery may continue to be consumed. Place the headset units with the IR sensors facing sideways or upwards.
  3. Attach the earbud tip.

    Firmly insert the earbud tip all the way. 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 and the sound quality, noise canceling effects, and wearability may be impaired.

  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.
