INTRODUCTION
Sharp's pioneering research and achievement
in
electronic engineering have finally
developed
the
ultra
compact
and efficient machine.
Newly developed Super mini-sized calculator EL-801
is
a tYpical pocket-size
calculator having as many features
as possible.
The
unit can be
operated
on
four UM-3
type
dry
batteries,
and
on
optional
rechargeable
Ni-Cd batteries.
Small sized
but
has
the
great power.
An
ideal calculator
that
goes anywhere with you.

Be
sure
not
to
take the positive pole for
the
negative pole.
3. Replace the
battery
case after setting four
