Precautions

On Bluetooth communications

  • Bluetooth wireless technology operates within a range of about 10 m (30 feet). Maximum communication range may vary depending on obstacles (the human body, metal, walls, etc.) or electromagnetic environments.
  • Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off this headset and other Bluetooth devices in the following locations, as it may cause an accident:
    • in a hospital, near the priority seat on the train, where inflammable gas is present such as a petrol station
    • near automatic doors or a fire alarm
  • This product emits radio waves when used in wireless mode.
    When used in wireless mode on an airplane, follow flight crew directions regarding permissible use of products in wireless mode.
  • Due to the characteristic of the wireless technology, the sound played on this headset is delayed from the sound and music played on the transmitting device. Therefore, the image and sound may be misaligned when viewing a movie or playing a game.
  • This headset supports security capabilities that comply with the Bluetooth standard to provide a secure connection when the Bluetooth wireless technology is used, but security may not be sufficient depending on the setting. Be careful when communicating using Bluetooth wireless technology.
  • We do not take any responsibility for the leakage of information during Bluetooth communications.
  • Connection with all Bluetooth devices cannot be guaranteed.
    • A device featuring Bluetooth function is required to conform to the Bluetooth standard specified by Bluetooth SIG, Inc. and be authenticated.
    • Even if the connected device conforms to the above mentioned Bluetooth standard, some devices may not connect or work correctly, depending on the features or specifications of the device.
    • While talking on the phone hands free, noise may occur, depending on the device or communication environment.
  • Depending on the device to be connected, it may require some time to start communications.
  • The headset does not support multipoint connection.
    If the headset supports the multipoint function, the headset can connect to a music playback device (A2DP profile, Walkman, etc.) and a communication device (HFP or HSP profile smartphone, etc.) at the same time, you can listen to music while waiting for an incoming call or making a call.

Note on static electricity

  • Static electricity accumulated in the body may cause mild tingling in your ears. To minimize the effect, wear clothes made from natural materials.

Note on wearing the headset

  • Because the headphones are of a high density enclosure, forcing them against your ears may result in eardrum damage. Pressing the headphones against your ears may produce a diaphragm click sound. This is not a malfunction.
