Data Safety - Lenovo ThinkCentre A58 Manual

The following notice applies to all countries and regions:
DANGER
Outdoor antenna grounding
If an outside antenna or cable system is connected to the
equipment, be sure the antenna or cable system is grounded as
to provide some protection against voltage surges and built-up
static charges.
Lightning
For added protection for this equipment during a lightning
storm, or when it is left unattended and unused for long periods
of time, unplug it from the wall outlet and disconnect the
antenna or cable system. This will prevent damage to the video
product due to lightning and power line surges.
Power lines
An outside antenna system should not be located in the vicinity
of overhead power lines or where it can fall into such power
lines or circuits. When installing an outside antenna system,
extreme care should be taken to keep from touching such power
lines or circuits, as contact with them may be fatal.
