Sharp xe a203 sd card error 99

SOURCE: Sharp XE-A203

Hi.
The XE-A203 does not use error numbers. It should tell you what is wrong in words. The 202 does use numbers. An error 2 on a 202 model just means you pressed the wrong buttons.
Can you please check the model number on the machine and make sure it is a 203? Also, does it do it as soon as you turn the key to REG? What happens if you try the key in other modes?
Please try to give me as much info as you can, and we can try to sort it out.

According to my manual, the cards should be formatted on a Windows PC. Insert the card into any computer and wait for it to be recognized. Access the card's memory by clicking on the icon in the "My Computer" (or equivalent) window. BE SURE THERE IS NOTHING ON THE CARD THAT YOU WILL LOSE. This process will erase everything on the card. Right-click on the card's icon. Click "Format." Set formatting options to FAT memory. Set the allocation size to 16. Start formatting. Double-check your manual to be sure for the specifics on your exact model of calculator.
