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.
