—This picture appears when the equipment has been out of ope-
ration for several months. Previously stored Basic Keys are
cleared e.g. because of discharge of the internal accumula-

2.3.1., page 25) the same picture appears.
—The pairs of hyphens always refer to empty storage places,
ready to store the new Basic Keys to be entered.
—6different identification bigrams (random letter pairs
between Aand Z) of stored Basic Keys are offered to the
operator.
