2.2.6 CompactFlash
The CompactFlash card serves as a mass storage device, i.e. for storing the
operating system, the applications and configuration data. As a result the
disadvantages involved with the use of a rotating harddisk are avoided, thus
improving the reliability of the system substantially since a CompactFlash has
an MTBF of at least 4,000,000 hours.
The CompactFlash adapter is simply connected to the IDE bus of the CPU
module and treated just like a hard disk.

With the power supply switched off the CompactFlash card can simply be
taken out or inserted enabling a quick change to different hardware.

CMOS Lithium Battery
The onboard CMOS RAM stores system configuration data and has an
onboard battery power supply. The long-life Lithium battery has normally a
lifetime of at least 5 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.
For opening the case 3 screws on the top must be removed. The battery
holder is soldered in the Mainboard and well visible.
Attention
: Open-frame
power supplies 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
(3 V DC, CR2032).
Used batteries are to
be disposed absolutely in accordance with the manufacturer's instructions.
Please pay attention to the correct polarity!
