KEY OPERATION
Key Touch
Depress
the
keys accurately.
If two keys
are depressed simultaneously,
all
digit indica-
tors flash at
the
same intervals and stop
further operation.
How to Enter the
Numerals
For
right hand operation, place
the index
finger on
the
(4] key,
the
middle finger on
the
(8) key
and
third
finger on
the
[8]
key.
Make
a
habit of
keeping your fingers
in
these
positions.
Thus,
depress
the
left
column
(1)
(4
keys with the index
finger,
the middle column
[2]
(&]
keys
with the middle finger, and
the
right
column
(3) keys with the
third
finger. With practice, blind
operation
will
soon become possible.
Notes:
* Even when
the
numeral keys and
function
keys are depressed at random, nothing
is
the matter
with
the calculator. In this case,
depress
the
key to clear
all
entries to
the
registers.
* Over a period
of
time,
paper dust,
particles and
other
residues will
accumulate
on
the characters
of the
printing drum,
resulting
in
unclear or indistinct prints.
To avoid this, it
is
recommended
that the
printing drum be cleaned with a
stiff brush
when
10
paper rolls have been used; or at
least once every
three months.
* Avoid using
the calculator
in
direct sun-
light.
