Backup copies
At the end of a work session, always remember
to copy all newly elaborated data present on Hard
disk to floppy disks. Should the Hard disk suffer
damage and data loss, you will always be able to
recuperate the data from disks.
If you work with floppy disks only, it is a good
idea to prepare a second copy of the disk at the
end of your work session. To copy data from one
disk to another, you must first copy the original
data to RAM then save (or copy) to the backup
copy disk.
WARNING - Never turn off the instrument while
the Hard disk or disk drive are writing data (Save,
Copy, Move, Erase operations).
HARD DISK SLEEP TIME
To avoid hearing the noise caused by the rota-
tion of the hard disk, you can set this parameter
to turn the hard disk off after an operation.
Options: Off (always on), 5 sec ... 60 sec.
HARD DISK PROTECTION (F8)
As a safety measure to prevent unwanted file
loss, all WK4 instruments with factory fitted Hard
Disks leave the factory with the Hard Disk Pro-
tection active (shown in negative highlight).
In order to use the Save, Erase or Move opera-
tions on the Hard Disk, the protection must be
removed.
Simply press the soft button F8 to deactivate the
protection. The option turns positive.
