The NC-60 has been designed to be used for active noise cancelling and so audio performance has been optimised
for this mode. For your convenience, when the batteries become flat or are removed, the headphones will continue to
operate in passive mode.
Operation
1. Adjust the volume of the NC-60 using the Volume Control (3)
2. Switch on the Noise Cancelling feature by sliding the On/Off Switch (4) to On; the Noise Cancelling Indicator (5) will
illuminate Blue
3. After you turn the Noise Cancelling feature on you may hear a slight hissing noise, this is completely normal and will
reduce after a few seconds and become inaudible during audio playback
4. When using the Noise Cancelling feature, if the battery level becomes low the Noise Cancelling Indicator will become
dim. If you continue to use the Noise Cancelling feature the battery will eventually drain, but the headphones will
continue to operate passively
