Maintenance
The instrument does not need periodic maintenance. Only cleaning the instrument is
essential.
Follow the instructions in the service manual and the safety instructions when
exchanging modules or ordering spare parts. The order number for spare parts is inclu-
ded in the service manual. The service manual includes further information particularly
on troubleshooting, repair, exchange of modules (including battery exchange, adjust-
ment of the OCXO oscillator) and alignment.
The address of our support center and a list of all Rohde & Schwarz service centers
can be found at the beginning of this manual.

Cleaning
Risk of electric shock
If moisture enters the casing, for example if you clean the instrument using a moist
cloth, contact with the instrument can lead to electric shock. Before cleaning the instru-
ment other than with a dry cloth, make sure that the instrument is switched off and dis-
connected from all power supplies.
Instrument damage caused by cleaning agents
Cleaning agents contain substances such as solvents (thinners, acetone, etc.), acids,
bases, or other substances. Solvents can damage the front panel labeling, plastic
parts, or screens, for example.
Never use cleaning agents to clean the outside of the instrument. Use a soft, dry, lint-
free dust cloth instead.
Risk of instrument damage due to obstructed fans
If the instrument is operated in dusty areas, the fans become obstructed by dust or
other particles over time. Check and clean the fans regularly to ensure that they always
operate properly. If the instrument is run with obstructed fans for a longer period, the
instrument overheats, which can disturb the operation and even cause damage.
1. Clean the outside of the instrument using a soft, dry, lint-free dust cloth.
