Cleaning the Set-Top
Before cleaning this set-top, unplug it from the

aerosol cleaner. Do not use a magnetic/static
cleaning device (dust remover) to clean this
set-top.

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

Accessories
Do not use accessories with this set-top unless
recommended by your cable service provider.
Grounding
This set-top has a two-prong plug. Properly
ground (earth) this set-top by inserting the plug
into a grounded electrical, two-socket outlet. If
this plug is polarized, it has one wide prong and
one narrow prong. This plug fits only one way.
CAUTION:
To prevent electric shock, match wide blade of
plug to the wide slot, and then fully insert.
Overloading
Do not overload electrical outlets, extension
cords, or 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.
If you are unable to insert this plug fully into the
outlet, contact an electrician to replace your
obsolete outlet.
Servicing
Do not open the cover of this set-top. If you open
the cover, your warranty will be void. Refer all
servicing to qualified personnel only. Contact
your cable service provider for instructions.
Damage that Requires Service
For damage that requires service, unplug this
set-top from the electrical outlet. Refer to qualified personnel when any of the following occurs:
• There is damage to the power cord or plug
• Liquid enters the set-top
• There is exposure to rain or water
• Operation is not normal (the instructions in this
guide describe the proper operation)
• If you drop this equipment, or damage the
cabinet of this set-top
• If this set-top exhibits a distinct change in
performance
Upon completion of any service or repairs to this
set-top (home terminal), the service technician
will perform safety checks to determine that the
equipment is in proper operating condition.
