Maintenance
Cleaning
Make sure to unplug the main power supply of amplifier prior to cleaning.
The panels and chassis can be cleaned with a soft cloth and mild non-abrasive cleaning
solution.
Avoid cleaning powders or scrubbing pads, as these will scratch and dull the paint. Do not apply
liquid directly to the surface. Dampen the cloth with the cleaning solution and wipe gently.
Dust removal
After used the unit for a long-time, especially in dusty environments, the heat sinks may become
clogged with dust. This will interfere with cooling from the air inlets, and lead to higher
temperature operation and reduced life.
Dust can be most easily removed by brushing or directing an air jet between the fins of the heat
sinks.
User maintenance
User maintenance should be done by qualified personnel only.
Dangerous mains voltages are present inside the units. Unplug the main power supply before
you do any maintenance.
Users can inspect if any broken connectors, ground, cable connections, or loose screws on the
outside of amplifier.
If any loose parts rattle around on the inside when the amplifier is turned over in all directions,
please shut down the amplifier immediately, as a loose part could lodge in a dangerous place
and cause further damage or shock hazard.

If proper operation cannot be restored, the amplifier may require service from ATEÏS Technical
