Care & Maintenance
To remove dust from the cabinet of the Nº33, use a feather duster. To remove dirt
and fingerprints, we recommend isopropyl alcohol and a soft cloth. Apply the al-
cohol to the cloth first and then lightly clean the surface of the Nº33.
Caution! At no time should liquid cleaners be applied directly to the
Nº33, as direct application of liquids may result in damage to
electronic components within the unit.
