IMPORTANT SAFETY INSTRUCTIONS
Maintenance
(See page 30 for details.)
Unplug the unit from the household AC outlet before clean-
ing.
Clean with a damp cloth.
Do not use abrasive pads, scouring powders, or solvents.
Service
1. Damage requiring service—The unit should be serv-
iced by qualified service personnel if:
(a) The AC power supply cord or the plug has been
damaged; or
(b) Objects or liquids have gotten into the unit; or
(c) The unit has been exposed to rain; or
(d) The unit does not operate normally or exhibits a
marked change in performance; or
(e) The unit has been dropped or the cabinet damaged.
2. Servicing—Do not attempt to service the unit beyond
that described in these operating instructions. Refer all
other servicing to authorized servicing personnel.
3. Replacement parts—When parts need replacing en-
sure the servicer uses parts specified by the manufac-
turer or parts that have the same characteristics as the
original parts. Unauthorized substitutes may result in
fire, electric shock, or other hazards.
4. Safety check—After repairs or service, ask the servicer
to perform safety checks to confirm that the unit is in
proper working condition.
3. Power lines—Take care when setting up an outdoor
antenna that it is not near overhead power lines, elec-
tric lights, or electrical circuits, and that there is no dan-
ger 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 out-
door antenna, ground the antenna system to protect
against voltage surges and built-up static charges. Sec-
tion 810 of the National Electrical Code, ANSI/NFPA
No. 70-1990, provides information about 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, connec-
tion to grounding electrodes, and requirements for the
grounding electrode. Refer to this diagram.

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 ensures 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 outlet. 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 disconnecting it.
4. Overloading—When connecting the AC power supply
cord, be careful not to overload the household AC out-
let, extension cord, or outlet from any other device as
this can result in fire or electric 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 attach-
ments and accessories recommended in these operat-
ing instructions.
Installation
Placement
1. Ventilation—Situate the unit so that it receives proper
ventilation. 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 cur-
tains and other materials do not obstruct the unit’s ven-
tilation.
2. Foreign material—Ensure objects and liquids do not
get into the unit. Avoid exposing the unit to excessive
smoke, dust, mechanical 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 5˚C (41˚F)
or rise above 35˚C (95˚F).
