!0 Screw holes for security cover
If desired, you can use these two screw holes for attaching
the included security cover to prevent the attenuator setting
from being changed. Use the included Allen wrench and
screws to attach the cover.
!1 Air intakes
The amplifier uses forced-air cooling. The variable speed
cooling fan draws air in from the front and exhausts it
through the rear. The cooling fan operates at low speed when
the heat sink temperature is below 65 °C (149 °F), or at high
speed when the temperature exceeds 65 °C (140 °F). Please
be sure that you do not block the air intakes or exhaust vents.
