Cleaning
SHOCK HAZARD To prevent electric shock, disconnect the ac mains before
attempting the following cleaning procedures.
Cleaning the Outside
Clean the outside of the instrument with a soft, lint-free, slightly damp cloth. Do not use detergent.
Disassembly is not required or recommended for cleaning the outside. Ensure that the instrument is
completely dry before turning it on.
Cleaning the Filter
1. Remove the filter housing by removing the four T10 screws that secure the housing.
2. Remove the filter from the front panel.
3. Shake the filter to remove the dust and particles that are attached to the filter. If the filter is
extremely dirty, clean the filter using water-diluted neutral detergent. Be careful not to damage the
filter material. Ensure that the filter is completely dry before installing it.
4. Install the filter in the front panel. Firmly attach the filter so the metal tabs protrude into the slits in
the filter. Note that the filter is asymmetrical and can only be correctly installed one way.
