Care And Maintenance - Classe Audio CA-M600 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 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 will flash (combined 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. Once the amplifier enters standby mode it will require reset to
operate normally (press and hold the standby button). Use this opportunity to
check and clean the air intake filter. Remove the front panel (CT series amps) or
the air intake cover (Delta series amps) to access the filter.
