* On rare occasions, noise may occur when the headphone plug is connected and turned 90 degrees
to lock it. Unless noise is heard with the plug in the locked position, it is not a problem. However,
if noise or uneven reproduction volume occurs, there is a possibility that the headphone plug has
become dirty. In such a case, wipe the plug with a dry cloth.
