Formatting a Memory Card 
A memory card that users use for the first time may not be formatted. A memory card which is not formatted 
can not be used in an AH500 series CPU module. Therefore, users need to format the memory card. The file 
system with which the memory card is formatted is FAT. 
The following example introduces the most common way to format an SD card, that is, formatting an SD card 
through a card reader. However, users still need to read the documents provided by the SD card manufacturer 
carefully. 
 
(1)  Slide the write protect tab on the left side of the memory card upward, and then insert it into a card reader. 
The operating system detects a new storage device. 
 
 
(2)  Right-click the new storage device, and then click Format. 
 
 
 
 
 
 
Slide the write 
protect tab 
upward. 
If a memory card is formatted, all the data in the memory card will be deleted. Users have to check 
whether the data in a memory card needs to be back
ed up before they format the memory card. 
Click Format.
