Maintenance

Perform regular maintenance by following the procedures below.

  1. Clean the headset.

    Cleaning the headset units

    Dust and dirt on the exterior of the headset and fitting supporter 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.

    If foreign material such as earwax becomes attached to the sound output hole, the sound may become muffled or difficult to hear.

    In this case, you can wipe off the dirt with pure water type wet wipes.

    Remove the dirt so that it does not push into the sound output hole.

    Do not use wet wipes containing alcohol, thinner, benzene, etc. as they may cause malfunction or damage.

    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.
  2. 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.
