• However, every battery has a limited service life! After several
hundred charging cycles, this limitation will become evident as
the operating times get significantly shorter.
• The replaceable battery supplies power to a backup battery,
which is permanently installed in the camera. This backup
battery retains the date and time for some weeks. Once the
backup battery is depleted, it must be replenished by inserting a
charged main battery. The time and date will have to be set
again after a full depletion of both batteries.
• As the battery capacity deteriorates or if using an older battery,
warning messages may appear and some functions may be
restricted or blocked entirely.
• Always remove the battery if the camera will not be used for an
extended period of time. Make sure to switch the camera off via
the main switch before removing the battery. Leaving the battery
in the camera will result in a deep discharge after a few weeks.
Voltage levels will decrease significantly, as the camera uses a
low idle current to maintain settings.
• Dispose of damaged batteries in accordance with the relevant
regulations at an approved collection point for proper recycling.
• The date of manufacture can be found on the battery. The date
format is week/year.
MEMORY CARD
• The range of available SD/SDHC/SDXC cards on the market is
too extensive for Leica Camera AG to test for compatibility and
quality. Generally, any type of memory card may be used without
any damage to the camera or memory card. As some "no name"
cards may not fully comply with the SD/SDHC/SDXC standards,
Leica Camera AG cannot provide any guarantee of function.
• We recommend formatting memory cards from time to time, as
fragmented residual data from deleted files may block some of
the storage capacity.
• Generally, it is not necessary to format (initialize) memory cards
that have been previously used. Formatting will, however, be
necessary if you insert an unformatted memory card or a card
that was formatted in another device (e.g. a computer) for the
first time.
• We recommend backing up your data on a PC, because
electromagnetic fields, static electricity and any damage to the
memory card or camera defects may result in irretrievable
damage or loss of your data.
• SD, SDHC, and SDXC memory cards come with a write
protection slider to prevent accidental overwriting. This slider is
located on the non-beveled side of the card. All data on the card
is protected when the slider is set to its lower position, marked
LOCK.
• All data stored on a memory card will be lost during formatting.
Formatting will not be prevented by the deletion protection set
for individual pictures.
