Noise canceling function
The noise canceling circuit actually senses outside noise with built-in microphones and sends an equal-but-opposite canceling signal to the headset.
- The noise canceling effect may not be pronounced in a very quiet environment, or some noise may be heard.
- Depending on how you wear the unit, the noise canceling effect may vary or a beeping sound (howling) may occur. In these cases, take off the unit and put it on again.
- The noise canceling function works for noise in the low frequency band primarily. Although noise is reduced, it is not canceled completely.
- When you use the unit in a train or a car, noise may occur depending on street conditions.
- Mobile phones may cause interference and noise. Should this occur, locate the unit further away from the mobile phone.
- Do not cover the microphones of the unit with your hands. The noise canceling function or the Ambient Sound Mode may not work properly, or a beeping sound (howling) may occur. In these cases, take your hands off of the microphones of the unit.
