1 Safety and regulatory information
The product documentation helps you use the product safely and efficiently. Follow the
instructions provided here and in the following chapters.
Intended use
The R&S QPS Walk2000 is a millimeter-wave security scanner designed to screen
people at security checkpoints. The system automatically detects metallic and
non‑metallic objects of all types concealed inside or beneath clothing. Use the product
only for its designated purpose. Observe the operating conditions and performance
limits stated in the data sheet.
Where do I find safety information?
Safety information is part of the product documentation. It warns you of potential dan-
gers and gives instructions on how to prevent personal injury or damage caused by
dangerous situations. Safety information is provided as follows:
●In Chapter 1.1, "Safety instructions", on page 5. The same information is provi-
ded in many languages as printed safety instructions. The printed safety instruc-
tions are delivered with the product.
●Throughout the documentation, safety instructions are provided when you need to
take care during setup or operation.
1.1 Safety instructions
Products from the Rohde & Schwarz group of companies are manufactured according
to the highest technical standards. To use the products safely, follow the instructions
provided here and in the product documentation. Keep the product documentation
nearby and offer it to other users.
Use the product only for its intended use and within its performance limits. Intended
use and limits are described in the product documentation such as the data sheet,
manuals and the printed "Safety Instructions". If you are unsure about the appropriate
use, contact Rohde & Schwarz customer service.
Using the product requires specialists or specially trained personnel. These users also
need sound knowledge of at least one of the languages in which the user interfaces
and the product documentation are available.
Never open the casing of the product. Only service personnel authorized by
Rohde & Schwarz are allowed to repair the product. If any part of the product is dam-
aged or broken, stop using the product. Contact Rohde & Schwarz customer service at
http://www.customersupport.rohde-schwarz.com.
Lifting, carrying and installing the scanner
Installation, setup and disassembly must be performed by trained personnel. Install the
R&S QPS Walk2000 exactly as described in the installation manual. During the instal-
Safety instructions

lation, make sure that the installation site is only accessible by people working on the
installation.
The R&S QPS Walk2000 gate elements, the floorplate, the transport boxes and the
server are heavy. Lifting and carrying heavy items can cause structural or muscular
injuries. Heavy items can also cause other physical injuries like crushed body parts
when they fall or tip over.
Because of its weight, at least two strong people are required to install or disassemble
the system. If you have to move the pallets the R&S QPS Walk2000 is delivered on,
always use a forklift.
The transport box is made of wood that can pose a risk of drawing splinters.
During transport, installation, disassembly or repair, wear appropriate protective cloth-
ing that complies with your local rules and regulations. If you are unsure of which
equipment to use, ask your safety inspector.
We recommend to wear:
●Safety shoes with toe cap and ESD protection.
●Protective gloves
ESD protected shoes and gloves also protect the hardware from being damaged.
Installing cables
A R&S QPS Walk2000 installation consisting of the gate, operator touchscreen and
server requires cable connections (power cables, LAN cables etc.). Secure all cables
on the floor and cover them up.
Loose cables are a tripping hazard. Tripping on cables can cause physical injuries.
Properly covered cables also minimize the risk of cable damage.
Choosing the operating site
Only use the product indoors. The product casing is not waterproof. Water that enters
can electrically connect the casing with live parts, which can lead to electric shock,
serious personal injury or death if you touch the casing. If Rohde & Schwarz provides
accessories designed for your product, e.g. a carrying bag, you can use the product
outdoors.
Unless otherwise specified, you can operate the product up to an altitude of 2000 m
above sea level. The product is suitable for pollution degree 2 environments where
nonconductive contamination can occur. For more information on environmental condi-
tions such as ambient temperature and humidity, see the data sheet.
Connecting to power
The product is an overvoltage category II product. Connect the product to a fixed
installation used to supply energy-consuming equipment such as household applian-
ces and similar loads. Keep in mind that electrically powered products have risks, such
as electric shock, fire, personal injury or even death.

Take the following measures for your safety:
●Before switching on the product, ensure that the voltage and frequency indicated
on the product match the available power source. If the power adapter does not
adjust automatically, set the correct value and check the rating of the fuse.
●If a product has an exchangeable fuse, its type and characteristics are indicated
next to the fuse holder. Before changing the fuse, switch off the product and dis-
connect it from the power source. How to change the fuse is described in the prod-
uct documentation.
●Only use the power cable delivered with the product. It complies with country-spe-
cific safety requirements. Only insert the plug into an outlet with protective conduc-
tor terminal.
●Only use intact cables and route them carefully so that they cannot be damaged.
Check the power cables regularly to ensure that they are undamaged. Also ensure
that nobody can trip over loose cables.
●If the product needs an external power supply, use the power supply that is deliv-
ered with the product or that is recommended in the product documentation or a
power supply that conforms to the country-specific regulations.
●Only connect the product to a power source with a fuse protection of maximum
20 A.
●Ensure that you can disconnect the product from the power source at any time.
Pull the power plug to disconnect the product. The power plug must be easily
accessible. If the product is integrated into a system that does not meet these
requirements, provide an easily accessible circuit breaker at the system level.
Meaning of safety labels
Safety labels on the product warn against potential hazards.
