The Circuit Breaker Reset Buttons (PUSH TO RE-
SET) are located on the back panel to protect the
power supplies against overload. If a circuit breaker
trips, the Signal/ IOC indicator of the affected channel
turns on (the Enable indicator remains illuminated).
4.5 Filter Cleaning
Dust filters are provided on the air intakes to the cool-
ing system (Figure 2.1). If these filters become
clogged, the unit will not cool as efficiently as it should
and may produce lower-than-normal output levels due
to high heat diffuser temperature and activation of the
ODEP circuitry.
To clean, remove each of the filter elements by gently
pulling them away from the front panel. Clean with mild
dishwashing detergent and warm water. Replacement
filters may be ordered from the factory.
Dust filters are not 100% efficient—depending on the
local environment, the internal heat sinks of the ampli-
fier will benefit from periodic cleaning by a qualified
technician. Internal cleaning information is available
from our Technical Support Group.
