3 Maintenance
3.1 Cleaning
Clean the outside of the R&S DDF205 using a soft, lint-free dust cloth.
Damage caused by cleaning agents
Cleaning agents contain substances that may damage the R&S DDF205, e.g.
solvent-containing cleaning agents may damage the front panel labeling or
plastic parts. Never use cleaning agents such as solvents (thinners, acetone,
etc), acids, bases, or other substances.
3.2 Storing and Packing
The R&S DDF205
can be stored at the temperature range quoted in the specifica-
tions (check the "Service" section in the Operating Manual). When it is stored for a
longer period of time the R&S DDF205 should be protected against dust. The orig-
inal packing should be used, particularly the protective caps at the front and rear,
when the R&S DDF205 is to be transported or dispatched. If the original packing is
no longer available, use a sturdy cardboard box of suitable size and carefully wrap
the R&S DDF205 to protect it against mechanical damage.
3.3 Test Points
There are voltage and temperature checks at many test points of the R&S DDF205
modules. Some of these test points depend on each other. The error messaging
system
considers these dependencies and reports only the causal source of errors.
A detailed guideline describing how to read each of the test points can be found in
the "Maintenance" section of the Operating Manual.
