Using Peripheral Devices

❑The noise canceling function is to reduce low-frequency noise in the ambient environment 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, unplug 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 is normal and does not indicate a malfunction. Be sure to take off the headphones from your ears before plugging or unplugging the headphones.

❑Enabling/disabling the noise canceling function or enabling/disabling sound with the Windows volume controls generates noise. This is caused by switching the noise canceling circuit and does not indicate a malfunction.

❑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 with such headphones.
