Power Supply

The type of battery you should use depends on the model
number of your calculator.

< fx-991W/ fx-115W >

The TWO WAY POWER system actually has two power
supplies: a solar cell and a G13 Type (LR44) button bat-
tery. Normally, calculators equipped with a solar cell alone
can operate only when relatively bright light is present.
The TWO WAY POWER system, however, lets you con-
tinue to use the calculator as long as there is enough light
to read the display.

• Replacing the Battery

Either of the following symptoms indicates battery power
is low, and that the battery should be replaced.
• Display figures are dim and difficult to read in areas

where there is little light available.

• Nothing appears on the display when you press the

5

key.

• To replace the battery

1

Remove the six screws that
hold the back cover in place
and then remove the back
cover.

2

Remove the old battery.

3

Wipe off the sides of new bat-
tery with a dry, soft cloth. Load
it into the unit with the posi-
tive

k

side facing up (so you

can see it).

4

Replace the back cover and
secure it in place with the six
screws.

5

Press

5

to turn power on. Be

sure not to skip this step.
