1.8 Precautions
• For projects that use memory cards, always insert the memory card before turning the MICRO/I on.
• The maximum number of screenshots that can be captured can be set in HG Special Registers LSD65.
• Memory cards have a limitation on the number of writes allowed. Regularly backup data on the memory card.
• Never turn the power off or remove the memory card while reading/writing to it. Otherwise, the data on the
memory card may be destroyed. Should this occur, reformat the memory card.
• Perform one of the following actions before turning power off to the MICRO/I, or removing the memory card.
- After setting HG special relay LSM20 to 1, check that HG special relay LSM21 is 0. Then remove the memory
card.
- For models HG2F/3F/4F, press the Access Pause button. The Access Lamp begins to blink and when reading/
writing to the CF card stops, the lamp goes out. Then, remove the CF card.
• When a read/write failure occurs with the memory card, HG special register LSD42 is set with the error status. For
details about the error, refer to Chapter 32 “2 Internal MICRO/I Devices” on page 32-2.
• If your computer does not have a memory card slot, an external memory card reader is required to read/write to
the memory card.
• If an unusable memory card is inserted, the error message “This CF card (SD Memory Card) not available” appears.
• Altering folders and files in the Memory Card Folder on the memory card will make the memory card unusable in
MICRO/I and WindO/I-NV2.
