3. Power lines—Take care when setting up an outdoor antenna

that it is not near overhead power lines, electric lights, or electri-

cal circuits, and that there is no danger of the antenna falling on

power lines, electric lights, or electrical circuits. When installing

an outdoor antenna, take extreme care not to touch such power

lines or circuits, as contact with them can be fatal.

4. Outdoor antenna grounding—If you connect an outdoor an-

tenna, ground the antenna system to protect against voltage

surges and built-up static charges. Section 810 of the National

Electrical Code, ANSI/NFPA No. 70-1990, provides information

about grounding of the mast and supporting structure, ground-

ing of the lead-in wire to an antenna discharge unit, size of

grounding conductors, location of antenna-discharge unit, con-

nection to grounding electrodes, and requirements for the

grounding electrode. Refer to this diagram.

(See page 35 for details.)

Unplug the unit from the household AC outlet before cleaning.

Clean with a damp cloth.

1. Damage requiring service—The unit should be serviced by

qualified service personnel if:

(a) The AC power supply cord or the plug has been damaged;

(b) Objects or liquids have gotten into the unit; or

2. Servicing—Do not attempt to service the unit beyond that de-

scribed in these operating instructions. Refer all other servicing

to authorized servicing personnel.

3. Replacement parts—When parts need replacing ensure the

have the same characteristics as the original parts. Unautho-

rized substitutes may result in fire, electric shock, or other

hazards.

4. Safety check—After repairs or service, ask the servicer to per-

IMPORTANT SAFETY INSTRUCTIONS

Read these operating instructions carefully before using the unit. Follow the safety instructions on the unit and the safety precautions listed

below. Keep these operating instructions handy for future reference.

Safety

1. Power source—Connect the unit to a power source of the type

described in these instructions or as marked on the unit.

2. Polarization—The unit is equipped with a polarized power plug

where one blade is wider than the other. This safety feature en-

sures that the plug fits into your household AC outlet only one

way. If the plug doesn’t fit one way, try reversing it. If the plug

still doesn’t fit, contact an electrician to replace the obsolete out-

let. Do not attempt to defeat the safety purpose of the plug.

3. Power cord protection—Route the AC power supply cord so

that it will not be walked on or pinched by items placed on or

against it. Never take hold of the plug or cord with wet hands.

Always grasp the plug body firmly when connecting and discon-

necting it.

4. Overloading—When connecting the AC power supply cord, be

careful not to overload the household AC outlet, extension cord,

or outlet from any other device as this can result in fire or elec-

tric shock.

5. Nonuse periods—Turn the unit off when it is not in use. Unplug

the unit from the household AC outlet if it is not to be used for a

long time. Unplug the unit during lightning storms.

6. Attachments and accessories—Use only the attachments and

accessories recommended in these operating instructions.

Installation

Placement

1. Ventilation—Situate the unit so that it receives proper ventila-

tion. Do not install in a confined space such as a bookcase or

cabinet. Allow at least 10 cm (4 inches) clearance from the rear

of the unit. To prevent the risk of electric shock or fire due to

overheating ensure curtains and other materials do not obstruct

the unit’s ventilation.

2. Foreign material—Ensure objects and liquids do not get into

the unit. Avoid exposing the unit to excessive smoke, dust, me-

chanical vibration, and shock.

3. Magnetism—Situate the unit away from equipment and devices

that generate strong magnetic fields.

4. Stacking—Do not place heavy objects on top of this unit.

5. Surface—Place the unit on a flat, level surface.

6. Carts and stands—Use the unit only with carts

and stands recommended by the manufacturer.

Move carts with care. Sudden stops, excessive

force, and uneven surfaces can cause carts to

overturn.

7. Wall and ceiling mounting—Do not mount the unit on walls or

ceilings unless specified in the instructions.

Environment

1. Water and moisture—Do not use the unit near water, such as

near a bathtub or swimming pool. Avoid damp basements.

2. Heat—Situate the unit away from heat sources, such as

radiators.

Do not situate where temperatures fall below 5oC (41oF) or rise

above 35oC (95oF).

Item 2 in “Safety” applies only in the U.S.A. and Canada.
