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 spe-
cialists) 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 chem -
icals, 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 bayo-
net. 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 M8.
2 for a long period of time. Other -
wise, after several weeks the battery could become
totally discharged, i.e. the voltage is significantly
reduced, as the LEICA M8.2 uses a low no-load cur-
rent (to save the date) even when it is turned off.
• Lithium ion batteries should be stored only in the
partially charged condition (the top panel LCD [1.12]
shows a value in the range , to ). 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. While lithium ion batteries are
proof against short circuits, they should still be pro-
tected 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 M8.
2.
• Batteries have only a limited service life.
• Take damaged batteries to a collection point to
ensure correct recycling.
• Never throw batteries into a fire as this can cause
them to explode.
For the charger
• If the charger is used in the vicinity of radio receiv -
ers, it can interfere with the reception; make sure
there is a distance of at least 1m between the devices.
• When the charger is in use, it can make a noise
(buzzing) – this is quite normal and is not a malfunc-
tion.
• When it is not in use, disconnect the charger from
the mains as otherwise it uses a certain (very small)
amount of power even when no battery is inserted
in it.
• Always keep the charger contacts clean, and never
short circuit them.
