Inserting/Removing a Memory Card
Purpose of the Memory Card
By using a memory card, you can
Store the operating system, user programs and data (similar to using a
diskette);
Transport the programs and data stored on the memory card;
Retain the programs and data, even during Power Off.
Inserting/Removing the Memory Card
A memory card should only be inserted or removed when no access to the
memory card is taking place, in other words, the "SD" indicator on the FM 456-2
must be OFF. Figure 2-13 shows how to insert a memory card in an FM 456-2.
Warning
!
Data may be lost when the memory card is inserted or removed.
If write access to the memory card occurs when the memory card is being inserted
or removed, data consistency cannot be guaranteed.
If you are not certain whether write access to the memory card is still possible,
then remove it only when the power is off.
