ya battery or rechargeable battery is inserted and

y the normal/bypass sliding switch is in the “normal“ position (see page 10).

To switch off NoiseGard 2.0:

Press the ON/OFF button approx. 1 second.

The LED goes out. If NoiseGard is switched off, you can use the PXC 450 like typical headphones to listen to music.

Note:

– Compared to the other buttons of the controller, the ON/OFF button is set somewhat lower to avoid accidental switching off.
