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.
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 outlet, 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 attachments and 
accessories recommended in these operating instructions.
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 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, 
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.
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
o
C (41
o
F) or rise 
above 35
o
C (95
o
F).
3. Power lines—Take care when setting up an outdoor antenna 
that it is not near overhead power lines, electric lights, or 
electrical 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 
antenna, 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, 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. Refer to this diagram.
(See page 35 for details.)
Unplug the unit from the household AC outlet before cleaning.
Clean with a damp cloth.
Do not use abrasive pads, scouring powders, or solvents.
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; 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 ensure the 
servicer uses parts specified by the manufacturer 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.
