Using the Noise Canceling Headphones
❑The noise canceling function is to reduce low-frequency noise in the ambient environmen t but not high-frequency noise.
Nor is it to implement a 100% noise-free audio environment.
❑When the noise canceling function does not seem to be working, unpl ug the supplied noise canceling headphones
completely and then plug them back again.
❑Keep the built-in microphone (1) of the noise canceling headphones unblocked to ensure that the noise canceling function
can be fully in effect.
❑You may hear a soft hissing noise while the noise canceling function is enabled. This is just operational noise that the
function generates and does not indicate a malfunction.
❑You may feel that the noise canceling function has little effect or ambient noise seems even louder, depending on the type
of noise or the degree of quietness in your environment. In such a case, disable the noise canceling function.
❑Use of a mobile phone may cause radio interference with the noise canceling headphones. When using the headphones,
keep mobile phones away from the headphones.
❑Plugging or unplugging the noise canceling headphones generates noise. This i s normal and does not indicate a
malfunction. Be sure to take off the headphones from your ears before plugging or unplugging the he adphones.
❑Enabling/disabling the noise canceling function or enabling/disabling sound with the Wi ndows volume controls generates
noise. This is caused by switching the noise canceling circuit and does not indicate a malf unction.
❑Be sure to use the supplied noise canceling headphones. You can plug the headphones supplied with a Walkman® to
your computer but the noise canceling function of the computer will not work well wit h such headphones.
