8.1
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.
2. Check and clean the fans regularly to ensure that they always operate properly.
