IMPORTANT SAFETY INSTRUCTIONS
(continued)
15) Apparatus should not be exposed to dripping or splashing, and objects filled with
liquids, such as vases, should not be placed on the apparatus.
16) An outside antenna system should not be located in the vicinity of overhead power
lines or other electric light or power circuits, 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 might be fatal.
17) Do not overload wall outlets and extension cords, as this can result in a risk of fire or
electric shock.
18) Do not push objects through any openings in this unit, as they may touch dangerous
voltage points or short out parts that could result in fire or electric shock. Never spill or
spray any type of liquid into the unit.
19) If an outside antenna or cable system is
connected to the unit, be sure the antenna
or cable system is grounded to provide
some protection against voltage surges
and built-up static charges, Section 810
of the National Electrical Code, ANSI/
NFPA 70, provides information with
respect to proper grounding of the mast
and supporting structure, grounding of the
lead-in wire to an antenna discharge unit,
size of grounding conductors, location
of antenna discharge unit, connection to
grounding electrodes, and requirements for the grounding electrode.
20) When replacement parts are required, be sure the service technician uses replacement
parts specified by the manufacturer or those that have the same characteristics as the
original part.
Unauthorized substitutions may result in fire, electric shock or other hazards.
21) Upon completion of any service or repairs to this unit, ask the service technician to
perform safety checks to determine that the unit is in proper operating condition.
22) When you connect the product to other equipment, turn off the power and unplug all of
the equipment from the wall outlet. Failure to do so may cause an electric shock and
serious personal injury. Read the owner's manual of the other equipment carefully and
follow the instructions when making any connections.
23) Do not allow the product to output distorted sound for an extended period of time. It
may cause speaker overheating and fire.
24) This reminder is provided to call the cable TV system installer’s attention to Article 820-
40 of the NEC that provides guidelines for proper grounding and, in particular, specifies
that the cable ground shall be connected to the grounding system of the building, as
close to the point of cable entry as practical.
25) The mains plug is used as the disconnect and shall remain readily operable.
WARNING: Never place a television set in an unstable location. A television set that falls or
is unintentionally pulled down can and cause, serious personal injury or death.
Most such injuries, particularly to children, can be avoided by taking simple
precautions including :
- Use cabinets or stands recommended by the manufacturer of the television
set.
- Only use furniture that can safely support the television set and equip the
television set with a set of safety straps or similar products to anchor the
television set to a wall or a similarly immovable support.
- Ensure the television set is not overhanging the edge of the supporting
furniture.
- Do not place the television set on tall furniture (for example, on top of
cupboards or bookcases) If you decide you must place the television set on tall
furniture, absolutely do not do so without anchoring BOTH the furniture AND
the television set to a wall or a similarly immovable support.
