6. Should a fire occur, the product may release hazardous substances (gases,
fluids, etc.) that can cause health problems. Therefore, suitable measures
must be taken, e.g. protective masks and protective clothing must be worn.
7. Laser products are given warning labels that are standardized according to
their laser class. Lasers can cause biological harm due to the properties of
their radiation and due to their extremely concentrated electromagnetic power.
If a laser product (e.g. a CD/DVD drive) is integrated into a Rohde & Schwarz
product, absolutely no other settings or functions may be used as described in
the product documentation. The objective is to prevent personal injury (e.g.
due to laser beams).
8. EMC classes (in line with EN 55011/CISPR 11, and analogously with EN
55022/CISPR 22, EN 55032/CISPR 32)
Class A equipment:
Equipment suitable for use in all environments except residential
environments and environments that are directly connected to a low-
voltage supply network that supplies residential buildings
Note: Class A equipment is intended for use in an industrial environment.
This equipment may cause radio disturbances in residential environments,
due to possible conducted as well as radiated disturbances. In this case,
the operator may be required to take appropriate measures to eliminate
these disturbances.
Class B equipment:
Equipment suitable for use in residential environments and environments
that are directly connected to a low-voltage supply network that supplies
residential buildings
Repair and service
1. The product may be opened only by authorized, specially trained personnel.
Before any work is performed on the product or before the product is opened,
it must be disconnected from the AC supply network. Otherwise, personnel will
be exposed to the risk of an electric shock.
2. Adjustments, replacement of parts, maintenance and repair may be performed
only by electrical experts authorized by Rohde & Schwarz. Only original parts
may be used for replacing parts relevant to safety (e.g. power switches, power
transformers, fuses). A safety test must always be performed after parts
relevant to safety have been replaced (visual inspection, protective conductor
test, insulation resistance measurement, leakage current measurement,
functional test). This helps ensure the continued safety of the product.
