PLACE
At the ''F'' position, the decimal floats and the un-
derflow system works to protect the significant
digits.
At the ''3'', "'2"' or ''0"' position, an
answer is
automatically rounded off at each decimal place
(3, 2 or O}.
Note: Each entry is rounded off in addition/subtrac-
tion. However, the final result is rounded off
in x /+ operation and entry and intermedi-
ate results are in the floating mode.
At the ""ADD(2)"' position, numbers with decimal
places can be entered without pressing the (+) key
in addition/subtraction and the decimal point is
automatically
displayed
and/or printed out at 2
decimal position.

*Be careful not to drop the unit or handle it roughly.
* Avoid operating the keys roughly. Two or more
keys should not be pressed simultaneously as this
may damage the unit.
* Avoid using the unit in extreme temperatures (be-
low 32°F or O°C, or above 104°F or 40°C). Also
protect the unit from extremely dusty or humid
conditions.
*The unit should be operated only when the roll
paper is set property and keys are pressed firmly
and separately.
*Never use volatile fluid such as lacquer thinner,
benzine, etc. for cleaning the unit.
2-2 POWER SOURCE
This calculator operates by either dry batteries or
AC (with the AC adaptor}.
DRY
BATTERY
OPERATION
When battery power decreases, printing speed be-
comes slow. It is recommended that batteries be
renewed.
Switch off the power before changing.
Replacement of batteries:
1) Slide open the battery compartment tid.
2) Remove dead batteries.
3) Insert new batteries with the polarity as shown
by the (©
symbols.
4) Replace the battery compartment lid.
*Be sure to replace all four batteries.
*Do not Jeave dead batteries in the battery com-
partment as they may cause malfunctions.
*|t is recommended that batteries be replaced ev-
ery 2 years to prevent the chance of malfunctions
due to battery leakage.

AC OPERATION
Use only an adaptor with the same voltage rating
(100, 117, 220 or 240V) as your power supply
to prevent component
damage.
Plug the AC adaptor into the AC outlet and the cord
into the unit, this automatically cuts off battery
power supply.
"WHERE USED FROM THE MAINS THIS CALCU-
LATOR MUST ONLY BE USED WITH A CASIO
MAINS ADAPTOR. THIS IS DUE TO THE RISK OF
DAMAGE TO THE CALCULATOR SHOULD IT BE
USED WITH A MAINS ADAPTOR OTHER THAN
A CASIO MAINS ADAPTOR.
The following
burst.
1. Use of an AC adaptor other than a genuine Casio
adaptor.
2. insertion of batteries with incorrect polarities

BUFFER REGISTER
This calculator is equipped with an Input Buffer
Register which
retains up to 7 key-in, whether
numeral entries or function commands.
It enables very fast operation even while the previ-
ous function is still being processed.

culations,
and
various
kinds of practical calcu-
lations.
Capacity:
12 digits (FR-125S/HR-120S}, 10 digits {HR-110S)
Decimal! point:
Full floating, and fixed (0, 2 or 3) with round-off.
ADD mode:
Decimal point is fixed at 2 position.
Negative number:

2.6W
Power supply:
AC: 100, 117, 220 or 240V (+ 10V), 50/60Hz,
with an AC adaptor. (AD-4150}, 4.5V DC, tip
negative.
DC: (FR-125S8 /HR-1 20S)
Four AA size manganese dry batteries (UM-3)
operate the display for approximately 3 hours
continuously
(approx.
5.5
hours
on
type
SUM-3}, or the display and printer for approx-
imately 2100 lines of ''55555'' continuous-
