Please specify the make and model of the calculator. There so many make and model of the calculators in the market place. If you just need a general of how to used a calculator , then it's easy. Most calculators is the same basic. There is a plus key, minus, equation, division, M+, M-, MR, If you really want any manual please phone 780-424-1957
First a get cup or some sort of container to hold onto small parts.
Turn the calculator over on its back. You will need both a small phillips type screwdriver to remove the two small screws at the top. One that has been magnetized is best. Also you will need a small narrow bladed standard screwdriver to seperate the two halfs apart. Once you have removed the two screws and put them in a safe place it is time to open the case itself. Start near where one of the screws was and put the standard screwdriver in the groove between the halfs and gently start twisting it to pry the halfs apart. Work your way around the two halfs gently and slowly. There are plastic clips around the edge and they will slowly pop one after the other. Once you have the two halfs apart there is a small holder containing the battery. One side of the holder has a small gap. Slowly use your small standard screwdriver to push the battery gently though this gap from the far side. Mine had a GP189 button cell. You can go online and google 'GP189' and look for other rbatteries of this type. Same thing for putting the replacement battery back in. Just get it started with your fingers and push it in with the small standard screwdriver. If you don't have a small standard screwdriver a small dinner knife can be used to pry the halfs apart and anything small like that can be used to get the batteries in and out. Anything small of metal or bamboo comes to mind. As far as getting a new battery on the cheap try looking in 'Dollar Tree' type stores. If they don't sale the batteries themselves you can purchase a small generic calculator or any other small electronic and rob the battery from it. That's what I basically did in looking at other small calculators I already owned and robbing a battery from one of those. The very last step I took just before putting the calculator back together is noting the battery type and position and marking that on the back of the case with a fine tip sharpie.
The closest I could come up with was the operations manual from the predecessor model IV. It contains lots of examples, not simple key usage.
