CMOS Lithium Battery
The battery-backed CMOS stores the BIOS system settings. The long-life lithium battery has normally
a lifetime of at least six years.
If the CMOS battery is empty and the CMOS information has been deleted, the CMOS-RAM is
programmed by the BIOS with default settings.
The converter can be operated faultlessly even if the CMOS RAM is not provided by the battery. After
the battery has been changed, only time and date must be input.
Remove six screws on the top to open the housing. The battery holder is soldered in the mainboard
and well visible.
Attention!
Open-frame power supply units are used. Because of this, the process should be carried
out only by experienced electronic engineers. The device must be completely disconnected from any
power supply. Before opening please push the power button (without electricity supply) several times
to eliminate residual voltages of the power supply.
Battery replacement must be carried out by qualified specialists.
Caution!
Incorrect replacement might cause the danger of explosion. Replace the battery exclusively
by the same type
(model label: CR-2032)
.
The battery should be certified for air transport. Alternatively, it can be ordered directly from us.
Used batteries are to be disposed absolutely in accordance with the manufacturer's instructions.
Please pay attention to the correct polarity!
