4 Operation

This section describes how to operate the FEC 22 in the field. One section of the
display elements as well as the operating elements of the electronic insert are
protected by a cover. This can be raised by inserting a small screwdriver into a
recess in it. The inside of the cover has symbols to serve as a quick guide (see Table 5.1
for explanation)
