Changing lithium battery
In order to permanently save the system information, a lithium battery is installed to provide the
CMOS-memory with a current. A corresponding error message notifies the user when the charge is
too low or the battery is empty. The lithium battery must then be replaced.
!
Incorrect replacement of the lithium battery may lead to a risk of explosion!
The lithium battery may be replaced only with an identical battery or with a type
recommended by the manufacturer.
Do not throw lithium batteries into the household waste. They must be disposed of in
accordance with local regulations concerning special waste.
Make sure that you observe the correct polarity when replacing the lithium battery. The
plus pole must be on the top!
The lithium battery holder exists in different designs that function in the same way.
