Maintenance
The
CC-8A
requires virtually no maintenance as long as the unit is not exposed to direct sunlight,
moisture, voltage or current overloads, or extreme temperatures.
The
CC-8A
has high-friction rubber feet. These feet are soft, and should not be exposed to
petroleum based cleaners or solvents. They can, on occasion, leave a black mark on a cabinet or
desk like any soft rubber might do. Avoid stacking this unit on any cabinets where appearance is a
major concern.
A thermal, automatically-resetting fuse also protects the
CC-8A
and is located internally on the dc
output leads. The DC output fuse usually never needs to be replaced since the internal thermal fuse
resets in just a few seconds.
Clean the
CC-8A
with Windex
®
or other mild cleaners suitable for use on plastics. Avoid petroleum
products.
Lightning Protection
As with any electrical device, lightning is a concern. The robust construction and sturdy parts used
in the
CC-8A
offers a great deal of lightning and surge protection. The best protection is to
disconnect electrical devices during storms, and we have taken the unique step of providing
connectors on the rear of the
CC-8A
that unplug. We suggest unplugging the
CC-8A
control leads
when severe weather is expected. The use of a lightning protector, such as the
DXE-IS-RCT - DC
Shunt Control Line Protector
, available from DX Engineering, is prudent as well.
Proper grounding of feedlines and equipment and maintaining integrity of shield connections is
paramount to avoiding severe lightning damage. Consult lightning protection and station grounding
information in the ARRL handbooks, NAB Broadcast Handbook or other reliable sources. Always
remember good grounds and proper feedline connections improve lightning protection and
transmitting and receiving performance.
