Appendix A Resetting the Calculator
Warning!
The procedure described here clears all memory contents. Never perform this
operation unless you want to totally clear the memory of the calculator. If you
need the data currently stored in memory, be sure to write it down somewhere
before performing the RESET operation.
uTo reset the calculator
F
1. Highlight the MEM icon on the main menu and then press w, or press t.
2. Use c to move the highlighting down to “Reset” and then press w.

3. Press 1 (YES) to reset the calculator or 6 (NO) to abort the operation
without resetting anything.
4. Press m.
P.11

• If the display appears to dark or dim after you reset the calculator, adjust the
contrast.
Resetting the Calculator
• If the calculator stops operating correctly for
some reason, use a thin, pointed object to
press the P button on the back of the
calculator. This should make the RESET
screen appear on the display. Perform the
procedure to complete the RESET operation.
Appendix A
P button
• Pressing the P button while an internal calculation is being performed will
cause all data in memory to be deleted.

Appendix B
Power Supply
This calculator is powered by four AAA-size (LR03 (AM4) or R03 (UM-4))
batteries. In addition, it uses a single CR2032 lithium battery as a back up power
supply for the memory.
If the following message appears on the display, immediately turn off the calculator
and replace batteries.
If you try to continue using the calculator, it will automatically turn off in order to
protect memory contents. You will not be able to turn power back on until you
replace batteries.
Be sure to replace the main batteries at least once every two years, no matter how
much you use the calculator during that time.
The batteries that come with this calculator discharge slightly during shipment and
storage. Because of this, they may require replacement sooner than the normal
expected battery life.
Warning!
All memory contents will be deleted if you remove both the main power supply
and the memory back up batteries at the same time. If you ever remove both
batteries, correctly reload them and then perform the reset operation.
k Replacing Batteries
Precautions:
Incorrectly using batteries can cause them to burst or leak, possibly damaging the
interior of the calculator. Note the following precautions:
• Be sure that the positive (+) and negative (–) poles of each battery are facing in
the proper directions.
• Never mix batteries of different types.
• Never mix old batteries and new ones.
• Never leave dead batteries in the battery
compartment.
• Remove the batteries if you do not plan
to use the calculator for long periods.
• Never try to recharge the batteries
supplied with the calculator.
• Do not expose batteries to direct heat, let them become shorted, or try to take
them apart.

Power Supply
Appendix B
(Should a battery leak, clean out the battery compartment of the calculator
immediately, taking care to avoid letting the battery fluid come into direct
contact with your skin.)
Keep batteries out of the reach of small children. If swallowed, consult with a
physician immediately.
uTo replace the main power supply batteries
* Never remove the main power supply and the memory back up batteries
from the calculator at the same time.
* Never turn on the calculator while the main power supply batteries are
removed or not loaded correctly. Doing so can cause memory data to be
deleted and malfunction of the calculator. If mishandling of batteries causes
such problems, correctly load batteries and then perform the RESET
operation to resume normal operation.
* Be sure to replace all four batteries with new ones.
1. Press !O to turn off the calculator.
Warning!
* Be sure to turn the calculator off before replacing batteries. Replacing
batteries with power on will cause data in memory to be deleted.
2. Making sure that you do not accidently press the o key, attach the case to
the calculator and then turn it over.
3. Remove the back cover from the calculator by
pulling with your finger at the point marked 1.
1
4. Remove the four old batteries.
5. Load a new set of four batteries, making sure that
their positive (+) and negative (–) ends are facing in
the proper directions.
6. Replace the back cover.
7. Turn the calculator front side up and remove its case.
Next, press o to turn on power.
BACK UP
433
Appendix B
Power Supply
• Power supplied by memory back up battery while the main power supply
batteries are removed for replacement retains memory contents.
• Do not leave the calculator without main power supply batteries loaded for long
periods. Doing so can cause deletion of data stored in memory.
• If the figures on the display appear too light and hard to see after you turn on
power, adjust the contrast.
uTo replace the memory back up battery
* Before replacing the memory back up battery, turn on the calculator and
check to see if the “Low battery!” message appears on the display. If it does,
replace the main power supply batteries before replacing the back up power
supply battery.
* Never remove the main power supply and the memory back up batteries
from the calculator at the same time.
* Be sure to replace the back up power supply battery at least once 2 years,
regardless of how much you use the calculator during that time. Failure to do
so can cause data in memory to be deleted.
1. Press !O to turn off the calculator.
Warning!
* Be sure to turn the calculator off before replacing batteries. Replacing
batteries with power on will cause data in memory to be deleted.
2. Making sure that you do not accidently press the o key, attach the case to
the calculator and then turn it over.
3. Remove the back cover from the calculator by
pulling with your finger at the point marked 1.

4. Remove screw i on the back of the calculator, and
remove the back up battery compartment cover.
5. Insert a thin, pointed non-metal object
(such as a toothpick) into the hole maked j
and remove the old battery.

6. Wipe off the surfaces of a new battery with a soft,
dry cloth. Load it into the calculator so that its positive
(+) side is facing up.
BACK UP
7. Install the memory protection battery cover onto the
calculator and secure it in place with the screw.
Next, replace the back cover.
8. Turn the calculator front side up and remove its case. Next, press o to turn
on power.
k About the Auto Power Off Function
Calculator power turns off automatically if you do not perform any key operation
for about 6 minutes. To restore power, press o.

* For a single calculation, calculation error is ±1 at the 10th digit. (In the case of exponential display,
calculation error is ±1 at the last significant digit.) Errors are cumulative in the case of consecutive
calculations, which can also cause them to become large. (This is also true of internal consecutive
calculations that are performed in the case of ^(xy), x y, x!, 3 x, nPr, nCr, etc.)
In the vicinity of a function’s singular point and point of inflection, errors are cumulative and may
become large.

GUIDELINES LAID DOWN BY FCC RULES FOR USE OF THE UNIT IN THE U.S.A. (not applicable to other areas).
NOTICE
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
FCC WARNING
Changes or modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
Proper connectors must be used for connection to host computer and/or peripherals in order to
