3. Clean the interior of the chamber with a vacuum cleaner.
Run the vacuum cleaner on a low power setting and move its nozzle carefully, to
avoid damaging the absorber material in the chamber.
4.
NOTICE! Do not use liquid cleaning agents such as contact spray. Liquid agents
can cause malfunction and damage to electrical interfaces and mechanical parts.
Clean the outside of the chamber with a dry cloth.
Do not touch the gasket.
5. Optionally, activate the chamber as described in Chapter 7.1, "Activating the
Chamber" , on page 42.
9.4.4 Cleaning the Gasket
The gasket contact area can be soiled, for example by sweat or grease from finger-
prints. Clean the gasket every 100
000 cycles to maintain RF shielding.
To clean the door's gasket

on page 44.
2. Deactivate the chamber as described in Chapter 7.2, "Deactivating the Chamber" ,
on page 43.
Deactivation prevents any door movement that can lead to collision during cleaning
activities.

● Soft, lint-free cleaning cloth
● Alcohol
● Soft brush
4. Carefully use the soft brush in a dry condition to pre-clean the gasket.
5. Carefully use the cloth and alcohol to remove any soil from the gasket's nickel-
coated contact area.
6. Optionally, activate the chamber as described in Chapter 7.1, "Activating the
Chamber" , on page 42.

When the test system's instruments to which the chamber is connected are calibrated,
make sure that the chamber is included in this calibration procedure. Calibration is per-
formed typically once a year.
