1、Format memory card correctly. Please choose corresponding digital device to format card, if format directly in the card reader, which may result in the card not to be recognized because the control chips of card reader and digital device(camera，cell phone，PDA etc) are different(different version or different standard）.
2、Using certified data line and card reader to transmit data can guarantee to stabilize card power because unstable voltage will hurt the card seriously.
3、You can not unplug or disconnect the card suddenly after connecting the card with host. You can take the card after the host system shutdown and power off. When the host crashes or you can not take the card from the host during connection process, you should disconnect the card manually after the power shut down.
4、Pay attention to indicator light. Indicator light may twinkle after finishing copy, and you can not disconnect the card at this time. It is not a correct way to disconnect with host software ，while we should operate it after the light without flashing. Try not to fill up the card capacity with copy files, and leaving a little space in the card can protect software.
5、Pay attention to saving and carrying card, too. You had better not carry the card to power distribution room, electroplating room, near welding machines, and some departments in hospital such as x-ray room, magnetic resonance, CT room etc. You also can not put it in the metal box. SD Card has not waterproof function，so do not use the card when it is wet，but you can use it after drying. Static electricity protection should not be ignored. |
