Environment Specifications
• The environment specifications given here are for a PL
that is built into a metal panel.
• The Digital Electronics Corporation does not guaran-
tee the preservation of any data stored on the HDD if
the HDD has an accident, malfunctions or is dam-
aged in any way. Therefore, the regular backing up of
important HDD data to either a floppy disk, or other
type of suitable magnetic media is strongly recom-
mended.
• This HDD has a finite usage lifetime. The lifetime
figure given in this document’s Performance Specifi-
cations is for reference, and the regular exchanging
of the current HDD unit for a new HDD unit is strongly
advised.
