4.3Replacing soft key labeling

(operating units with key-based front panels only)

The two horizontal and two vertical rows of soft keys of the operating units with key-based front panels can be assigned user-specific func- tions. You can use two printed labeling strips to identify the soft keys.

A4 foil sheets are available for you to prepare the strips for insertion.

Procedure:

1.Print the foil with a laser printer.

2.Cut the labeling strips along the preprinted lines.

3.Insert the strips through the slits provided on the rear side of the operating unit (see Figure 4-5).
