Care And Maintenance - Classe Audio CA-M300 Owner's Manual

Care and Maintenance

To remove dust from the cabinet of your amplifier, use a feather duster or a lint-
free soft cloth. To remove dirt and fingerprints, we recommend isopropyl alcohol
and a soft cloth. Dampen the cloth with alcohol first and then lightly clean the
surface of the amplifier with the cloth. Do not use excessive amounts of alcohol
that might drip off the cloth and into the amplifier.
Caution! At no time should liquid cleaners be applied directly to
the amplifier, as direct application of liquids may result
in damage to electronic components within the unit.
From time to time, the air intake filter behind the front panel will need to be
vacuum cleaned or removed and rinsed with clean fresh water. A pressure sensor
measures the airflow to determine when it is necessary to clean the filter. When
cleaning is required, the Standby LED button will flash red/blue and a message
will be sent to connected touchscreen controlled devices via the connected
CAN-Bus system. Since this is a maintenance and not a protection feature,
the amplifier will continue to operate while the LED is flashing, so as not to
interrupt a listening session.
