4. To activate noise-cancelling function, move the power switch up; the power indicator
should light (red). (If you do not wish to use the active noise-cancelling function, move
power switch to the down position.)
5. Turn on your audio device. (Volume should be set at a low level at first; adjust as
necessary on audio device.) To prevent damage to your eardrums, never use
excessive volume levels.
There is an in-line volume control on the cable provided with your ATH-ANC20 headphones,
which you may use to adjust volume of your music. Note that the maximum volume heard
through the headphones is limited by the setting on your music source. If the volume on
your source is at the minimum setting, you may not be able to hear your music adequately.
Noise-cancelling only
To activate noise-cancelling function, move the power switch on your headphones to the
"ON" position; power indicator should light (red). In this case, there is no need to connect
the headphone cable; simply turn the headphones on and wear them.
After using
When you have finished using your headphones, move the power switch to the
down position.
