Lightning Protection
To protect a Compaq product during a
lightning storm or when it will be unat-
tended and unused for long periods of time,
unplug the product from the electrical
outlet and disconnect the antenna or cable
system. This prevents damage to the
product due to lightning and power line
surges.
Power Lines
Do not place an outside antenna system in
the vicinity of overhead power lines or other
electric light or power circuits, or where it
can fall into power lines or circuits. When
installing an outside antenna system, take
extreme care to avoid touching power lines
or circuits, as contact with them could be
fatal.

for proper grounding and, in particular,
specifies that the cable ground shall be
connected to the grounding system of the
building, as close to the point of cable entry
as practical.
