The mode No. 111 is for S/N and crosstalk. The mode No. 115 is for distortion factor and frequency characteristics.

When the VOLUME +/– keys is pressed in any mode, the vol- ume of the headphones is changed (increased/decreased) in units of one step. When the +/ =keys is pressed, the volume of the headphones is maximized/minimized.

For the volume value, any changed value remains as it is basi- cally.

However, when the volume is switched from 114 to 115 or 118 to 119, it returns the default value.
