2) Press the MENU/SET button again to choose a noise cancel level. The levels switch in the following rotation, "OFF" "LOW" "HIGH".
Note: If the Noise Cancel level is set to "LOW" or "HIGH", the level setting is displayed for 5 seconds when a file is played back.
To change the Noise Cancel level setting, press the MENU/SET button while the level setting is displayed.
