5 Instrument Sanitization Procedure
5.1 Volatile Memory
Removing power
1. Turn off the R&S ZNH.
2. Remove the battery.
Leave the instrument powered off at least for 10 minutes to make sure that all vola-
tile memory modules lose their contents, see
[3] .
5.2 Non-volatile Memory
The Flash does not lose its contents when power is removed. It can contain user data.
Sanitizing the non-volatile memory
The Flash is cleared by executing the sanitizing procedure provided on the instrument.
The sanitizing procedure complies to the definition of NIST [1] , see "Terms defined in
Guidelines for Media Sanitization" on page 7.

NOTICE! Risk of loosing data. The sanitization procedure clears all user data and
resets the instrument.
Back up all data you want to keep.
2. Remove all media:
a) Disconnect USB mass memory.
b) Remove microSD card.
For information on how to proceed, see the corresponding instructions in the
user manual of the R&S
ZNH.
3. Keep the media memory devices under organizational control.
