2.2 Inserting the Labeling Strips
The function keys and softkeys are labeled using labeling strips which are
inserted into the keypad from the side.
When shipped, the function keys of the C7 are labeled with K1....K10 and
the softkeys with F1....F14.
A set of blank labeling strips is enclosed with the C7. They can be used for
plant-specific labeling of the C7.

Caution
The writing on the strips must be wipe-resistant before inserting. A keypad
membrane soiled on the inside cannot be cleaned and can only be replaced
in the factory.
A sheet with plant-specific labeling strips is also provided. The strips must be
cut off exactly along the marked line. If the labeling strips are too large, they
cannot be inserted into the keyboard.
Labeling strips can only be changed when the C7 is not installed. The sealing
ring should be replaced. Proceed as follows:

2. If possible, hold the labeling strip at the end you want to insert in the slit.
Hold the strip horizontally. Hold the strip by touching both surface areas
rather than the edges to facilitate insertion.
3. Slide the strips into the slits provided. The location of the slits is shown in
Figure 2-1. The strips are slid over the existing labeling.
4. To avoid bending the strip as you insert it, move it backwards and forwards
several times
