Button Test

The Button Test verifies the operation of each button on the operator

panel. When Button Test is selected, the following screen is

displayed.

While a button is pressed, CL (Closed) is displayed. Likewise, while

a button is not pressed, OP (Open) is displayed. If the wrong

message is displayed, then the button is malfunctioning.

To exit the button test, press Return or Stop. The previous menu

screen will be displayed when the button is released.

memory for the first time.
