Whenever it is possible to enter numeric val-
ues, the keys marked with 0-9; . (decimal
±
point) and
(stands for Change Sign) take on
their alternative numeric meaning.
It is often convenient to enter values using the
scientific format. For that purpose, the
rightmost softkey is marked EE (stands for
Enter Exponent), making it easy to switch be-
tween the mantissa and the exponent.
Press EXIT/OK to store the new value or
CANCEL to keep the old one.
