SAFETY INFORMATION (cont.)
In addition to the Important Safety Instructions, please read the Safety
Information below.
Power sources
The model number, serial number, and electrical rating of this set-top are
on a label on its base.
You must operate the set-top only from the type of power source indicated
on the marking label. If you are not sure of the type of power supply to
your home, consult your dealer or local power company. If you move the
set-top between locations at different temperatures, allow it to reach room
temperature before you apply power to it.
Overloading
Do not overload wall AC outlets, extension cords or other power outlets as
this can result in a risk of fire or electric shock.
Lightning
For added protection for the set-top during a lightning storm, or when
it is left unattended and unused for long periods of time, disconnect the
cable system from the set-top. See also item 13 in the Important Safety
Instructions.
Ambient temperature
The operating temperature range of the set-top is 32-104°F. If the ambient
temperature around the set-top falls outside this range, you must correct
this in order for the set-top to work correctly and safely. For example, if the
temperature is too high, make sure there is sufficient ventilation (see below)
and that the set-top is not directly on top of or underneath other equipment.
Ventilation
Slots and openings in the casing of the set-top are provided for ventilation,
to ensure reliable operation of the set-top and to protect it from overheating.
• Never block the ventilation openings by placing the set-top on a bed,
sofa, rug, or other similar surface. Place it on a hard, flat surface.
• Never cover the ventilation openings with items such as newspapers,
table-cloths, or curtains.
• You can place the set-top near other consumer electronics devices, such
as stereo amplifiers or televisions, but you must not place it directly on
top or underneath them.
• Do not place the set-top in a
built-in installation such as
a bookcase or rack unless
proper ventilation is provided
and you have adhered to the
manufacturer’s instructions.
•
Maintain a minimum
distance of three inches
around the set-top for
sufficient ventilation.

Water and moisture
Do not expose the set-top to rain or moisture, dripping or splashing, and
ensure that no objects filled with liquids, such as vases, are placed on the
set-top. See also item 5 in the Important Safety Instructions.
Entry of objects and liquids
Never push objects of any kind into the set-top through openings as they
may touch dangerous voltage points or short-out parts that could result in
fire or electric shock. Never spill liquid of any kind on the set-top.
Transporting
Move the combination of set-top and cart with care. Quick stops,
excessive force and uneven surfaces may cause the combination of set-top
and cart to overturn. See also item 12 in the Important Safety Instructions.
Placement and mounting
Do not place the set-top on an unstable or uneven surface. The set-top
may fall, causing serious injury to a child or adult and serious damage
to the set-top. If you mount the set-top, for example to a wall or ceiling,
follow the manufacturer’s instructions and use a mounting accessory
recommended by the manufacturer. See also item 12 in the Important
Safety Instructions.
Risk of fire or scorching
Never place naked flame sources, such as lighted candles, on or adjacent
to the set-top.
Replacement parts
When replacement parts are required, be sure that the service technician
has used replacement parts specified by the manufacturer or that have
the same characteristics as the original part. Unauthorized substitutions
may result in fire, electric shock or other hazards. See also item 14 in the
Important Safety Instructions.
Safety check
Upon completion of any servicing or repairs to the set-top, ask the service
technician to perform safety checks to determine that the set-top is in
its proper operating condition. See also item 14 in the Important Safety
Instructions.
