service at http://www.customersupport.rohde-schwarz.com.
Lifting and carrying the product
The maximum weight of the product is provided in the data sheet. To move the
product safely, you can use lifting or transporting equipment such as lift trucks
and forklifts. Follow the instructions provided by the equipment manufacturer.
The product is heavy. Do not move or carry the product by yourself. A single per-
son can only carry a maximum of 18 kg safely depending on age, gender and
physical condition. Look up the maximum weight in the data sheet. Use the prod-
uct handles to move or carry the product. Do not lift by the accessories mounted
on the product. Accessories are not designed to carry the weight of the product.
To move the product safely, you can use lifting or transporting equipment such as
lift trucks and forklifts. Follow the instructions provided by the equipment manu-
facturer.
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 elec-
tric 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 environ-
ments where nonconductive contamination can occur. For more information on
environmental conditions such as ambient temperature and humidity, see the
data sheet.
Setting up the product
Always place the product on a stable, flat and level surface with the bottom of the
product facing down. If the product is designed for different positions, secure the
product so that it cannot fall over.
If the product has foldable feet, always fold the feet completely in or out to ensure
stability. The feet can collapse if they are not folded out completely or if the prod-

uct is moved without lifting it. The foldable feet are designed to carry the weight of
the product, but not an extra load.
If stacking is possible, keep in mind that a stack of products can fall over and
cause injury.
If you mount products in a rack, ensure that the rack has sufficient load capacity
and stability. Observe the specifications of the rack manufacturer. Always install
the products from the bottom shelf to the top shelf so that the rack stands
securely. Secure the product so that it cannot fall off the rack.
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
appliances 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 indica-
ted 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 indica-
ted next to the fuse holder. Before changing the fuse, switch off the instrument
and disconnect it from the power source. How to change the fuse is described
in the product documentation.
●Only use the power cable delivered with the product. It complies with country-
specific safety requirements. Only insert the plug into an outlet with protective
conductor terminal.
●Only use intact cables and route them carefully so that they cannot be dam-
aged. 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
delivered with the product or that is recommended in the product documenta-
tion or a power supply that conforms to the country-specific regulations.
●Only connect the product to a power source with a fuse protection of maxi-
mum 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.
Using laser products
Lasers are classified according to their potential risk. If exposure to the laser
beam is possible, the product is labeled as shown in the table explaining the
safety labels.
Class 1M lasers
Safe for the naked eye. If you look into the laser beam with optical instruments
such as binoculars or eye loupes, you risk damaging your eyes.
Class 2 lasers
If you stare into the beam, you risk damaging your eyes.
Handling batteries safely
The product contains exchangeable or built-in lithium polymer or lithium ion cells
or batteries. The use of the word battery in the following always means all types.
Only the battery contents are potentially hazardous. As long as a battery is
undamaged and the seals remain intact, there is no danger.
Impact, shock or heat can cause damage such as dents, punctures and other
deformations. A damaged battery poses a risk of personal injury. Handle a dam-
aged or leaking battery with extreme care. Immediately ventilate the area since
the battery releases harmful gases. If you come into contact with the battery fluid,
immediately remove all contaminated clothing. Irritation can occur if the battery
fluid comes in contact with your skin or eyes. Immediately and thoroughly rinse
your skin or eyes with water and seek medical aid.
For safe handling, follow these rules:
●Do not short-circuit the battery.
●Do not mechanically damage the battery. Do not open or disassemble the bat-
tery.
●Do not expose the battery to high temperatures such as open flames, hot sur-
faces and sunlight.
●Only use the battery with the designated Rohde & Schwarz product.

●Only use the appropriate Rohde & Schwarz charger to charge the batteries. If
the batteries are improperly charged, there is a risk of explosion. For charging
and discharging temperature ranges, see the product documentation.
●Replace exchangeable batteries only with the same battery type.
●Store the battery in the product or use the product packaging.
●Dispose of exchangeable batteries separately from normal household waste
as specified by the local waste disposal agency.
If you disregard these rules, you risk serious personal injury or even death due to
explosion, fire or hazardous chemical substances. The product documentation
provides further details.
If exchangeable batteries or products with built-in batteries are defective, contact
the Rohde & Schwarz customer service. Rohde & Schwarz classifies the severity
of the defect. When returning batteries or Rohde & Schwarz products containing
batteries, use a carrier qualified to transport dangerous goods and notify the car-
rier of this classification. Follow the carrier’s transport stipulations in line with
IATA-DGR, IMDG-Code, ADR or RID.
Connecting headphones
Take the following measures to prevent hearing damage. Before using head-
phones, check the volume and reduce it if necessary. If you monitor varying sig-
nal levels, take off the headphones and wait until the signal has settled. Then
adjust the volume.
Cleaning the product
Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind that
the casing is not waterproof. Do not use liquid cleaning agents.
Meaning of safety labels
Safety labels on the product warn against potential hazards.
Potential hazard
Read the product documentation to avoid personal injury or product damage.
Heavy product
Be careful when lifting, moving or carrying the product. Carrying the product requires
a sufficient number of persons or transport equipment.
