will be displayed in the Preset window. Press the next desired level button, etc. When all selections have been made, perform
the switch by pressing an input button.

DIAGNOSTICS MODE
Although the CP 3832L and 3864L do not have “Menu,” “Level,” etc. buttons as such (because the buttons are used as level
selection keys), the “Diagnostic” functions are still available indirectly. To access these functions, the MPK cable on the rear
of the unit must first be disconnected. Then use the buttons as described below.
