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.

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.
