FOR LENSES
• Normally, a soft hair brush is sufficient to remove
dust from the outer lens elements. However, in case
of more stubborn dirt, they can be carefully cleaned
with a very clean, soft cloth that is completely free of
foreign matter, using circular motions from the inside
to the outside. We recommend micro-fiber cloths
(available from photographic and optical specialists)
that are stored in a protective container and can be
washed at temperatures of up to 40°C (without fabric
softener, never iron!). Cloths for cleaning glasses,
which are impregnated with chemicals, should not be
used as they can damage the lens glass.
• Take care not to scratch the 6-bit coding (1.11) in
the bayonet fastening, or to get it dirty. Take care
also that no grains of sand or similar particles enter
the fastening, where they could scratch the bayonet.
Never wet this component when cleaning it!
• For optimum front lens protection in unfavorable
photographic conditions (e.g. sand, salt water spray),
use transparent UVa filters. However, you should
bear in mind that, like all filters, they can cause
unwanted reflections in certain backlight situations
and with high contrasts. The generally recommended
lens hood also protects the lens from unintentional
fingerprints and the rain.
FOR THE BATTERY
Rechargeable lithium ion batteries generate power
through internal chemical reactions. These reactions
are also influenced by the external temperature and
humidity. Very high or low temperatures reduce the life
of the battery.
• Always remove the battery if you will not be using
the Leica M Monochrom for a long period of time.
Otherwise, after several weeks the battery could
become totally discharged, i.e. the voltage is
significantly reduced, as the Leica M Monochrom
uses a low no-load current (to save the date) even
when it is turned off.
• Lithium ion batteries should only be stored in a
partially charged condition, i.e. not completely
discharged or fully charged (in the corresponding
display in the monitor (1.32). For very long storage
periods, it should be charged up and discharged again
around once a year.
• Always ensure that the battery contacts are clean
and freely accessible. Whilst lithium ion batteries
are proof against short circuits, they should still be
protected against contact with metal objects such as
paper clips or jewelry. A short-circuited battery can
get very hot and cause severe burns.
• If a battery is dropped, check the casing and
the contacts immediately for any damage. Using
a damaged battery can damage the Leica M
Monochrom.
• In case of noise, discoloration, deformation,
overheating of leaking fluid, the battery must be
removed from the camera or charger immediately and
replaced. Continued use of the battery results in a
risk of overheating, leading to fire and/or explosion.
• In case of leaking fluid or a smell of burning, keep the
battery away from sources of heat. Leaked fluid can
catch fire.
• A safety valve in the battery guarantees that any
excess pressure caused by improper handling is
discharged safely.
• Batteries have only a limited service life.
• Take damaged batteries to a collection point to
ensure correct recycling.
• The batteries may not be exposed to heat, sunlight,
humidity or moisture for long periods. Likewise, the
batteries may not be placed in a microwave oven or a
high pressure container as this results in a risk of fire
or explosion.
