Precautions and care instructions

• 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.

• In addition to the type designation, every lens has its “personal” serial

number. Note this number in your documentation for security.

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 camera for a long

period of time. Otherwise, after several weeks the battery could become

totally discharged, i.e. the voltage is sharply reduced as the camera still

consumes a small amount of current (for saving your settings) 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). 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 camera.

• In case of noise, discoloration, deformation, overheating or 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, which can cause 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. We recommend replacing them

after around four years.

• 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.
