Notes on use
•Be sure to read the connected device’s user manual before use.
•Audio-Technica will not be liable in any way for any loss of data in the unlikely event that such losses should occur while using the product.
•On public transportation or in other public places, keep the volume low so as not to disturb other people.
•Minimize the volume on your device before connecting the product.
•When using the product in a dry environment, you may feel a tingling sensation in your ears. This is caused by static electricity accumulated on your body, not by product malfunction.
•Do not subject the product to strong impact.
•Do not store the product in direct sunlight, near heating devices, or in hot, humid, or dusty places. Additionally, do not allow the product to get wet.
•When the product is used for a long time, the product may become discolored due to ultraviolet light (especially direct sunlight) and wear.
•Make sure to hold the plug when connecting and disconnecting the USB charging cable. The USB charging cable may become severed or an accident may occur if you pull on the cable itself.
•When you are not using the USB charging cable, disconnect it from the product.
•If the product is placed in a bag while the USB charging cable is still connected, the USB charging cable may become caught, severed, or broken.
•When you are not using the product, store it in the included pouch.
•This product can be used to talk on the phone only when using a mobile telephone network. Support for telephony apps that use a mobile data network is not guaranteed.
•If you use the product near an electronic device or transmitter (such as a mobile phone), unwanted noise may be heard. In this case, move the product away from the electronic device or transmitter.
•If you use the product near a TV or radio antenna, noise may be seen or heard in the television or radio signal. In this case, move the product away from the TV or radio antenna.
•To protect the built-in rechargeable battery, charge it at least once every 6 months. If too much time passes between charges, the life of the rechargeable battery may be reduced, or the rechargeable battery may no longer be able to be charged.
•The volume of the product differs depending on if the noisecancelling function is on or off.
•The hear-through mode of the product allows you to hear the sounds around you through the built-in microphone while you are wearing the product. Depending on the volume of the music being played back, the surrounding sounds may be difficult to hear. In this case, turn down the volume of the music.
•When the hear-through mode is on, the volume of music, etc., is automatically reduced so the product can assimilate the ambient noise. This reduction in volume is normal; the product is not malfunctioning.
•Depending on your surroundings, the surrounding sounds may be difficult to hear even when using the product’s hear-through mode. Do not use the product in places that could be dangerous when you cannot hear the surrounding sounds, such as places with heavy traffic.
•Operate the touch sensor with one finger. Operating with a sharp-tipped object, such as a ballpoint pen or pencil, may not only result in incorrect operation, but could also damage or break the touch sensor.
•Do not tap (touch) the touch sensor with the very tip of your finger. Doing so may cause your fingernail to break.
•If the product does not operate at all or as intended when tapped, check to make sure that your other fingers, parts of your hand, or clothing are not in contact with the product when tapping. Also, the product may not operate correctly if you are wearing gloves or if your fingertips are dry.
•The product may not operate correctly if the touch sensor is dirty from sweat. Remove any dirt before operating the product.
About the active noise-cancelling function
The product is designed to use its built-in microphone to pick up noise from the surrounding environment (noise from vehicles, noise from air conditioners, etc.) and to cancel out that noise by producing sounds in negative phase. This results in a reduction in the sounds in your environment.
•The product’s noise-cancelling function mainly reduces noises of 300 Hz or lower. Because of this, it has almost no effect on noises above that frequency (ringtones, speaking voices, etc.).
•Not all sounds are cancelled.
•Depending on the type of noise (or in quiet locations), you may not notice the noise-cancelling effect.
•There is a “humming” sound when you turn on the noise-cancelling function. This is the sound of the noise-cancelling function operating; it is not a malfunction.
