(earth) your cable product to provide some protection against
voltage surges and built-up static charges. To avoid these voltage
3
surges that can be caused by lightning storms and power outages,
plug the 1840 into a surge protector to reduce the risk of damage.
Do not turn on the 1840 or TV yet. It may take several minutes for
the 1840 to receive the latest software, programming, and service
information. Wait until you see one of the following displays on the
