HOW TO SAVE - HOW TO VERSION UP

Since VA-76 has a flash memory for the System program registration, and a flash memory for the Variphrase pro­gram registration you can update:

-the System program, the test program or the Variphrase program by floppy disks

Item Required
VA-76 System Program up disk (code: 7771017000)
VA-7/5/76 Test program disk (code: 7770134001)
VA-7/76 VP Program up disk (code: 7770135001)

A

TTENTION:

The Test program was not installed in this instrument (otherwise it would have occupied too much memory
space).
If you want to install it, you have to load the Test Program from the "VA-76 Test program disk" you've been
provided with.

W

ARNING:

Loading the Test Program causes the System Program of your VA-76 to be lost. Therefore every time

you want to carry out some checks in your VA-76 and consequently have to install the related Test Program,
we strongly recommend you to make a back-up copy of your VA-76 current System program, according to
the procedure described in the << How to save the System V

ersion or the Test Program onto Floppy disk >>

paragraph.

Of course, once you've completed your checks, you'll have to reload the System Program (that had been erased
when installing the Test Program), as described in the << How to update the System Program or the T

est Program

by floppy disk >> paragraph.

How to visualize the “System Program” version
