To maintain splash proof performance

Note the following cautions carefully and use the headset correctly.

  • Do not drop the headset or expose it to mechanical shock. Doing so may deform or damage the headset, resulting in deterioration of splash proof performance.
  • Do not put the headset in water or use it in a humid place such as a bathroom.
  • The micro-USB port cover is important for maintaining splash proof performance. Make sure the micro-USB port cover is closed securely when you use the headset. If the cover has any foreign objects on it or is not completely closed, splash proof performance cannot be maintained. In addition, water may get into the headset and cause malfunctions.
  • Do not splash water forcibly against the cylindrical part from which sound is emitted. Doing so may deteriorate the splash proof performance of the headset.
  • Wipe off with a soft dry cloth any water that gets on the headset. If water remains in the earbud holes, the sound may seem low or not be audible at all. In this case, remove the earbuds and wipe off the water. Do not leave the headset with water on it in cold places as the water may freeze. In order to avoid malfunctions, make sure that you wipe off water after use.
