IMPORTANT SAFETY INSTRUCTIONS
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.
CONDENSATION
Moisture will form in the operating section of the unit if the unit is brought from cool
surroundings into a warm room or if the temperature of the room rises suddenly. When
this happens, unit's performance will be impaired. To prevent this, let the unit stand in its
new surroundings for about an hour before switching it on, or make sure that the room
temperature rises gradually.
Condensation may also form during the summer if the unit is exposed to the breeze from an
air conditioner. In such cases, change the location of the unit.
