Question about Office Equipment & Supplies
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.
