Battery Care
Rechargeable lithium ion batteries generate power through internal
chemical reactions. This reaction is influenced by ambient temperature
and humidity. Very high and low temperatures shorten the operating
time and service life of the batteries.
• Always remove the battery if you will not be using the camera for a
long period of time, as otherwise it could become totally dis-
charged after several weeks, i.e. its voltage drops to a very low
level.
• Lithium ion batteries should only be stored partly charged, i.e. not
when fully discharged or fully charged (see the corresponding
display). For very long storage periods, the battery should be
charged for around 15 minutes twice a year to prevent deep
discharge.
• Always ensure that the battery contacts are clean and freely acces-
sible. While lithium ion batteries are proofed 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.
• For the battery to charge, it must have a temperature of between
0°-35°C/32°-95°F (otherwise the charger does not turn on or
turns off again).
• If a battery is dropped, check the casing and the contacts
immediately for any damage. Using a damaged battery can damage
the camera.
• Batteries have a limited service life.
• Send defective batteries to an appropriate collection point for
proper recycling.
• Never throw batteries into a fire as this can cause them to explode.
Charger Care
• If the charger is used in the vicinity of radio receivers it can
interfere with reception; maintain a distance of at least 1m/3ft
between the devices.
• When the charger is in use, it can make a noise (buzzing) – this is
quite normal and is not a malfunction.
• 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.
• Always keep the charger contacts clean, and never short circuit
them.
