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.

431

•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.

•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.

kReplacing 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.

433

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.

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

434

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.

uu

uu

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.

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.

*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), xy, x!, 3x, nPr, nCr, etc.)

In the vicinity of a function’s singular point and point of inflection, errors are cumulative and may

become large.
