Inserting the memory card
Removing the memory card
Notes:
The range of SD/SDHC/SDXC cards is too large for Leica Camera AG
to be able to completely test all available types for compatibility
and quality. Although using other card types is not likely to damage
the camera or the card, some "no name" cards do not comply with
the SD/SDHC/SDXC standards, and Leica Camera AG is unable to
provide any guarantee that they will function correctly.
Video recordings in particular require a high write speed.
If the memory card cannot be inserted, check that it is aligned
correctly.
If you remove the bottom cover or take out the memory card when
the camera is turned on, the monitor displays the corresponding
warning messages instead of the normal displays:
–
Attention Bottom cover removed
–
Attention No card inserted.
As electromagnetic fi elds, electrostatic charge, and defects on the
camera or the card can lead to damage or loss of the data on the
memory card, we recommend that you also transfer the data to a
computer and save it there (see p. 220).
For the same reason, it is recommended that the card is always
stored in its antistatic cover.
