To change the tax rate, first press AC. Then press SET % for 2 seconds. Next, press TAX+, then enter the new or current tax rate. Enter the rate for a single digit tax rate such as 5% as 5, a single number; if you have a fractional percentage rate, such as 5.75%, enter it just that way: the 5, then a decimal and followed by 7& 5. Then press SET % again and you're done! I just did it on two of the calculators and it works. Hope this helps!

SOURCE: casio calculator problem

Seems to be a common problem on this otherwise great calculator that helped me through both high school and university. I've had mine for nearly 20 years and this problem showed up a few years ago. But I remember classmates reported the same problem when it was almost new.

If replacing batteries isn't helping, the problem is most likely caused by oxidation on the springs connecting the battery holder to the main PCB. The solution is as follows:

1. Remove the metal back cover (2 screws)
2. Remove the plastic back lid by removing the black screws (leave the batteries mounted) and CAREFULLY slide the back lid to the lower end (where the EXE button is located). Do not lift while sliding until the lid easily comes off.
3. On the back side of the plastic lid, very carefully bend the the two metal connectors ~1 mm on both batteryholders to increase their tension.
4. Clean the connecting pads on the PCB and the metal springs with de-oxidizer solvent.
5. Re-assemble and your 4500P calculator should be good as new.

Battery replacement J-10A


Good Morning Fhaas153

Looking at a J-10 picture on eBay
http://www.ebay.com/itm/VINTAGE-CASIO-J-10-ELECTRONIC-CALCULATOR-8-DIGIT-TESTED-/331587643662 , the picture of the rear says '1.5V battery x 2. Looking at this other shot
http://www.casio-calculator.com/Museum/Calculator/FGHIJ/J-10/Casio-J-10-back.jpg It looks like there is a fairly clear Slide-to-Open Battery door at the top of the rear panel. Given the battery rating at 1.5 Volts and the door size, I'd suspect it'll take either AA or AAA batteries. You should be able to slide the door and look, and most battery compartments will have an indication of the specific cell.

To be sure I'm covering both the what and the how, slide the door open. Remove old batteries if still there. Clean up contacts with a bit of fine steel wool if they are corroded or covered with old battery fuzz. Put new batteries in - negative end towards the coil springs generally. Replace sliding hatch.

Hoping this covers what you're looking for!

Battery for Casio D-20M


Turn calculator over. Look for some small screws. Loosen them, remove the cover. Notice how the two batteries look when they are in place (polarity) and replace them. Close the cover and tighten the screws again. You need two LR 44 batteries or equivalent.

Describe casio fx-991 es battery replacement


Ah! that perennial desire for eternity. The calculator uses solar power. It also have a battery. Under normal circumstances you won't need a battery, may be if you are living through a long Nuclear Winter.
Any way, just get a battery with the same characteristics as the one that shipped with the calculator: voltage, thickness, diameter. That is what counts.

Hello I am wanting an instruction manual for a Casio LR54x1 Calculator. Thanks Louise


LR54x1 is not the the model number of your calculator. It is the reference of the button battery you calculator uses.
Check your number model and then go to Casio support page http://www.casio.com/support/manuals/, click on "Calculators", agree to the Terms and Conditions, and look for your calculator.
If your calculator isn't listed, download the manual for the SL-450L under Standard Calculator. It will probably be suitable for your calculator too.
