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.
