Casio Fx-992s Scientific Calculator - Page 6 - Answered Questions & Fixed issues

I have searched casio and various old manual sites and at this point have found the following manual to be as close to what you are looking for among a multitude of variations. It is not a problem to find a manual to a FX-82C or FX-82AU but the A variation has eluded me: http://casio.edu.monacocorp.co.nz/products/fx82ausplus/pdf/Using_2082AU_20PLUS_20manual.pdf Notice that this comes from a New Zealand site. It makes me wonder if AU might relate to Australia. Only Casio support would know for sure.

Here is a user guide that should prove beneficial. I hope it helps. http://support.casio.com/en/manual/004/fx-300ES_PLUS_EN.pdf

You can't do that on Casio fx-991es plus calculator. Usually, infinity symbol available in calculators with CAS (Computer Algebra System).

hi meredyth. try this link out. manual for Casio HR 100TM Google Search

Found the manual but nothing about the sound. If I recall sometimes the part that makes the sound can be damaged when replacing the battery, open it up and check the (little wire type vibrating bar) sound bar and adjust if necessary. http://www.casiodigitalwatches.com/manuals/0809.pdf

Just a guess on this but I would say Page/Number ...Good Luck

If unit has been lobotomized, forget it.

The battery that came out of it will have a number/voltage on it... just replace it with same.. If this isn't possible, take the watch to Batteries.bulbs, etc,, they can fit it with one.

it is correct you are not taking m note of where the decimal point is on the read out

Watch the video. Casio HR 8TM

Shine a bright light on the calculator while indoors to charge up the internal battery. The solar cells don't need sunlight....just light to work.

Major key, don't ever play yourself

Hello Michel Dekock, Could not find your FR2500 (but close)... Has worked every time for me... Mount the paper roll on the wire bracket... feeding over the top of the ROLL (TOWARD THE MACHINE). With the keyboard FACING away from yourself Fold the FRONT EDGE of the PAPER on to the side to form a chisel point... and insert the point (folded side up) in the rear roller slot (paper feed)... As shown on FR2650 http://www.ebay.com/itm/Casio-FR2650TM-Printing-Calculator-FR2650TM-/122298781152?hash=item1c79934de0:g:bwEAAOSw44BYbWjv With the PRINT feature turned on the roll should be advancing while holding down the TOTAL key... Hold the key until the edge of the paper roll emerges from the machine. Hope that helps. (now you only have to freshen up the ink). https://en.wikipedia.org/wiki/Carnac_the_Magnificent%E2%80%8B
