Reconfiguring the BIOS Setup
If the battery replacement has been performed while the device is running or does not take
longer than 30 seconds when the device is switched off, the BIOS settings will be retained.
The SRAM and CMOS data of the SIMOTION P320-3 is certainly deleted only when the
battery is disconnected for a longer period of time (more than 15 minutes) and in the
switched-off state.
The BIOS Setup must be performed again if the data has been cleared. The CMOS data
must be restored to the default values; the date, time, and any special settings must be set
again.
Exception:
If the CMOS data has been saved previously with a USER profile, only the date and the time
may be set again. All other settings will be made automatically. This means that the default
values must not be loaded in this special case.
