Year 2000 Compliance
The 28i and 124i and their associated PC programs are unaffected by the date
change to year 2000. The system processes the Leap Year correctly and does
not require any additional upgrades or reprogramming. With 28i or 124i
EXCPRU or Base software 4.04 or higher, the system uses a four-digit date
code entry (e.g., 2000). Previous versions use a two-digit date code entry
(e.g., 00=2000).
The 384i and 704i and their associated PC programs are unaffected by the
date change to year 2000. The system processes the Leap Year correctly and
does not require any additional upgrades or reprogramming. With software
3.07.24 or higher or with 704i software, the systems use a four-digit date
code entry (e.g., 2000). Previous versions use a two-digit date code entry
(e.g., 00=2000).
