Operating Instructions
The
Series
8320
TENULINE®
Attenuators
should
function
faultlessly,
absorbing
and
converting
RF
energy
into
heat
indefinitely,
if
they
are
properly
maintained
and
not
subjected
to
an
overload.
Normal Operation
Note:
The
Series
8320
TENULINE®
Attenuators
are
not
intended
or
recommended
for
outdoor
use
where
they
will
be
unprotected
and
exposed
to
the
elements.
1.
Install
the
attenuator
in
the
transmission
line,
see
2.
(Model
8325)
Verify
the
Vent
Plug
has
been
installed,
see
3.
Proceed
according
to
the
transmitter
manufacturer’s
instructions.
The
attenuator
may
be
subjected
to
very
moderate
overloads
for
limited
periods
of
time
without
overheating.
However,
this
should
be
done
very
cautiously
to
guard
the
attenuator
against
the
dangers
of
overheating.
CAUTION
The
input
and
output
ends
of
these
attenuators
are
clearly
labeled.
Do
not
couple
an
attenuator
backwards
to
the
direction
of
power
flow.
Destruction
of
the
output
resistor
will
result.
WARNING
The
vent
plug
must
be
installed
at
all
times
when
the
unit
is
in
operation
or
cooling.
Always
check
to
ensure
vent
plug
is
installed
prior
to
operation.
Failure
to
do
this
could
result
in
damage
to
the
equipment
and
endanger
the
operator’s
safety.
WARNING
Using
the
attenuator
in
the
upper
end
of
its
power
dissipation
range
will
cause
the
housing
to
become
hot!
Care
should
be
exercised
in
touching
them.
