Precautions for
Products with
External
Television
Antenna
Connectors
In addition to the general precautions described earlier in this section, be sure to
observe the following precautions when using external television antennas with your
product. Failure to observe these precautions could result in fire, bodily injury, and
damage to the equipment.
Compatibility
Compaq television tuner cards with antenna connections should be used only with
Compaq personal computers that are intended for home use.
External television antenna grounding
If an outside antenna or cable system is connected to the product, be sure the antenna
or cable system is electrically grounded to protect against voltage surges and built-up
static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides
information about proper electrical grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size of grounding
conductors, location of antenna-discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
Lightning protection
To protect a Compaq product during a lightning storm or when it will be unattended
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.
