The FCD-E1 front panel contains three push buttons designated CURSOR,
SCROLL and ENTER. These buttons control the LCD display and let you view and
change FCD-E1 parameters.
CURSOR Moves the cursor among the fields in the current display.
SCROLL Changes the selected item. Press SCROLL to display the alternatives in the
selected field. Hold SCROLL down to scroll through the options
automatically.

• If the new value is valid, it replaces the old value and the change takes
effect immediately.
• If the new value is not valid, it is not accepted and FCD-E1 displays a
CONFIG ERROR message with a two-digit code in the second display
row. After a short time, the error message disappears and FCD-E1
returns to the original display. Refer to Chapter 5 for a list of error codes
and how to correct the errors.
