Cleaning the transmitter module (R&S
QAR-Z10)
1. Clean the horn antenna, cables and cable connectors carefully with a dry and soft,
lint-free dust cloth. Other cleaning materials can leave residue on the rubber coat-
ing of the absorber.
If there are bigger dirt particles in the inside of the horn antenna, pick them out
carefully with tweezers.
2. Clean the rest of the transmitter module with a soft, lint-free dust cloth. If neces-
sary, you can dampen the cloth.
If you are using a damp cloth, make sure that the horn antenna and cable connec-
tors do not get wet.
Cleaning the reference reflector (R&S
QAR-Z60)
► Clean the reference reflector carefully with a dry and soft, lint-free dust cloth.

tweezers.

Software Update
A software update requires an executable file that you can download and copy to a
memory stick.
Ask your local Rohde & Schwarz support for the corresponding file.
1. Copy the file into the root directory of the memory stick. No other files should be
present.
2. Connect the memory stick to one of the USB ports on the R&S
QAR.
3. Log in as an administrator.
4. Open the Windows Explorer and navigate to the memory stick.
5. Run the installer file.
The software update takes a few minutes.
When the software update is done, the system restarts.
