Precautions
You probably already know it but…
…. always turn on the password protection if you
connect the instrument to a public or unsecured
network. If not, the instrument is an easy victim for
cyber-attack. It is a good practice to always use a FTP
password regardless of the connection environment.
Also, enable a password protection for the NorRemote
program.
“Security” on page 146
… the microphone is an especially fragile device. It is
easily broken, so take care.

the preamplifier. This is the safest way to avoid damage
and access of dirt on the contact pin between the
preamplifier and microphone cartridge.
… keep the instrument in its carrying case, don’t leave
it everywhere.
… even the instrument is a field instrument, prevent it
from direct contact with dust and moisture.
… Nor150 is a measurement instrument; protect it from
