should be retained for future reference.

3

Heed Warnings – All warnings on the unit and in the
operating instructions should be adhered to.

4

Follow Instructions – All operating and other instructions
should be followed.

5

Water and Moisture – The unit should not be used near
water – for example, near a bathtub, washbowl, kitchen
sink, laundry tub, in a wet basement, or near a swimming
pool, etc.

6

Carts and Stands – The unit should be used only with a
cart or stand that is recommended by the manufacturer.

6A

A unit and cart combination should
be moved with care. Quick stops,
excessive force, and uneven
surfaces may cause the unit and 
cart combination to overturn.

7

Wall or Ceiling Mounting – The unit

should be mounted to a wall or ceiling only as
recommended by the manufacturer.

8

Ventilation – The unit should be situated so that its

location or position does not interfere with its proper
ventilation.  For example, the unit should not be situated
on a bed, sofa, rug, or similar surface, that may block the
ventilation openings; or placed in a built-in installation,
such as a bookcase or cabinet that may impede the flow
of air through the ventilation openings.

9

Heat – The unit should be situated away from heat

sources such as radiators, stoves, or other appliances that
produce heat.

10

Power Sources – The unit should be connected to a power
supply only of the type described in the operating
instructions or as marked on the unit.

11

Power-Cord Protection – Power-supply cords should be
routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the unit.

12

Cleaning – The unit should be cleaned only as
recommended by the manufacturer.

13

Nonuse Periods – The power cord of the unit should be
unplugged from the outlet when left unused for a long
period of time.

14

Object and Liquid Entry – Care should be taken so that
objects do not fall into and liquids are not spilled into the
inside of the unit.

15

Damage Requiring Service – The unit should be serviced
by qualified service personnel when:

A.

The power-supply cord or the plug has been damaged;

or

B.

Objects have fallen, or liquid has been spilled into the unit;

or

C.

The unit has been exposed to rain; or

D.

The unit does not appear to operate normally or exhibits a

marked change in performance; or

E.

The unit has been dropped, or the cabinet damaged.

16

Servicing – The user should not attempt to service the unit
beyond those means described in the operating
instructions.  All other servicing should be referred to
qualified service personnel.

17

Power Lines – An outdoor antenna should be located
away from power lines.

18

Grounding or Polarization – Precautions should be taken
so that the grounding or polarization is not defeated.

19

Outdoor Antenna Grounding – If an outside antenna is
connected to this unit, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges.  Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides
information with regard 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.

SAFETY INSTRUCTIONS

Note to CATV system installer:

This reminder is provided to call the CATV 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.

1

To ensure the finest performance, please read this
manual carefully.  Keep it in a safe place for future
reference.

2

Install your unit in a cool, dry, clean place – away from
windows, heat sources, and too much vibration, dust,
moisture or cold.  Avoid sources of hum (transformers,
motors).  To prevent fire or electrical shock, do not
expose to rain and water.

3

Do not operate the unit upside-down.  It may overheat,
possibly causing damage.

4

Never open the cabinet.  If a foreign object drops into
the set, contact your dealer.

5

Do not use force on switches, knobs or cords.  When
moving the set, first turn the unit off.  Then gently
disconnect the power plug and the cords connecting to
other equipment.  Never pull the cord itself.

6

Do not attempt to clean the unit with chemical solvents;
this might damage the finish.  Use a clean, dry cloth.
