Notes on Using SD Memory Cards
Keep away from children. SD memory cards are harmful if swallowed.
Do not touch the contacts with fingers or metal objects.
SD memory cards contain delicate electronic components. Do not subject them to excessive force, bend or drop them.
Do not disassemble or modify.
Avoid moisture.
Do not use or store in the following locations:
Places with high temperature, such as inside an enclosed car in the sunshine
Places exposed to direct sunlight
Humid or corrosive environments
Excessively dusty places
Be sure to use SD memory cards that are compliant with the standards supported by your tablet device. A wrong-size card may
become jammed in the slot, causing damage to your tablet device.
You cannot write data to an SD memory card that is write-protected.
It is recommended that you make a backup copy of important data.
To avoid losing stored data, keep SD memory cards away from static electricity or electrical noise that may interfere with the
card.
When carrying SD memory cards, be sure to put them in their case to avoid static electricity damage.
Before using an SD memory card with a device other than a tablet device, such as a digital camera or a portable audio player,
format (initialize) the SD memory card using that device.
Some devices may not support the file format for tablet devices and show you a message that recommends you to format the
card. If you encounter such a message, copy data from the card to your tablet device (or to other devices via the network) and
format the card using the device other than the tablet. Note that formatting a card will delete all current data contained in it. For
more details, refer to the manual of the device you are using.
Do not insert foreign objects into the SD memory card slot.
The SD memory card slot can be used for reading/writing supported cards only, and it cannot be used for other purposes.
