Object and Liquid Entry
Never push objects of any kind into this product
through openings as they may touch dangerous voltage
points or short out parts that could result in a fire or
electric shock. Do not expose this set-top to liquid or
moisture. Do not place this set-top on a wet surface. Do
not spill liquids on or near this set-top.

integral convenience receptacles, as this can result in a
risk of fire or electric shock. For equipment that
requires battery power or other sources to operate, refer
to the operating instructions for that equipment.
Lightning and Power Surges
Ground (earth) your cable system to provide some
protection against voltage surges and built-up static
charges. Plug your set-top into a surge protector to
reduce the risk of damage from lightning strikes and
power surges. If you have questions, call your cable
service provider.
Power Cord Protection
Arrange all power cords so that people cannot walk on
the cords, place objects on the cords, or place objects
against the cords, which can damage the cords. Give
particular attention to the cords at the point at which
the cord connects to the plug, at electrical outlets, and
at the places where the cords exit the set-top.
Power Sources
A label on this set-top indicates the correct power
source for this set-top. Operate this set-top only from
an electrical outlet that has the voltage and frequency
that the label indicates.
If you are unsure of the type of power supply to your
residence, consult your cable service provider or your
local power company.
