    Parameters are divided into groups, each called a “level.” Each of the set val- ues (setting items) in these levels is called a “parameter.” The parameters on the E5CN/CN-U/AN/EN are divided into the following eight levels. When the power is turned ON, all of the display lights for approximately one second.
