Sanitization
Procedure
Turn off
instrument
power.
Because this
32 MB memory
chip contains
20 MB of user
data (described
here) and 12
MB of firmware
memory, a
selective chip
erase is
performed.
User data areas
are selectively
and completely
sanitized by the
procedure
"Erase and
Sanitize All" on
page 32.
