Optimizing the noise canceling function to suit the wearer (NC Optimizer)
This function optimizes the noise canceling function by detecting the shape of your face, your hairstyle, how you wear the headset due to the presence or absence of glasses, or the pressure change in an airplane.
It is recommended that you run the NC Optimizer function when using the headset for the first time, when the wearing condition has been changed or when the air pressure changes between being on an airplane and on the ground, etc.
- Put on the headset with the power turned on.
- Press and hold the CUSTOM button for about 2 seconds until you hear the voice guidance say, “Optimizer start”.
Test signals will be heard during the optimization. When the optimizing process is finished, you will hear the voice guidance say, “Optimizer finished”.
