The lightning flash with arrowhead symbol, within an equilateral
triangle, is intended to alert the user to the presence of uninsulated
"dangerous voltage" within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to
alert the user to the presence of important operating and
maintenance (servicing) instructions in the literature accompanying
the appliance.
WARNING:
TO PREVENT FIRE OR SHOCK HAZARDS,
DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.
CAUTION:
TO INSURE PERSONAL SAFETY,
OBSERVE THE FOLLOWING RULES
REGARDING THE USE OF THIS UNIT.
1. Operate only from the power source
specified on the unit.
2. Avoid damaging the AC plug and power
cord.
2
3. Avoid improper installation and never
position the unit where good ventilation is
unattainable.
4. Do not allow objects or liquid into the

antenna for your safety.
IMPORTANT SAFEGUARDS
CAUTION:
Please read and retain for your safety.
Electrical energy can perform many useful
functions. This Appliance has been engineered
and manufactured to assure your personal
safety. But improper use can result in potential
electrical shock or fire hazards. In order not to
defeat the safeguards incorporated in this
Appliance, observe the following basic rules for
its installation, use and servicing.
And also follow all warnings and instructions
marked on your Appliance.
INSTALLATION
1 Your Appliance is equipped with a
grounding-type AC line plug (three-blade
type), a plug having a third (grounding)
pin.
(GROUNDING-TYPE)
This plug will only fit into a grounding-type
power outlet. This is a safety feature.
Should you be unable to insert the plug
into the outlet, contact your electrician to
replace your outlet. Do not defeat the
safety purpose of the grounding-type plug.
2 Operate the Appliance only from a power
source as indicated on the Appliance or
refer to the operating instructions for this
information. If you are not sure of the type
of power supply to your home, consult
your Appliance dealer or local power
company. For battery operation, refer to
the operating instructions.
3 Overloaded AC outlets and extension
cords are dangerous, and so are frayed
power cords and broken plugs. They may
result in a shock or fire hazard. Call your
service technician for replacement.
4 Do not allow anything to rest on or roll
over the power cord, and do not place the
Appliance where power cord is subject to
traffic or abuse. This may result in a shock
or fire hazard.
5 Do not use this Appliance near water —
for example, near a bathtub, washbowl,
kitchen sink, or laundry tub, in a wet
basement, or near swimming pool, etc.
6 If an outside antenna is connected to the
Appliance, be sure the antenna system is
grounded so as to provide some protection
against voltage surges and built-up static
charges. Section 810 of the National
Electrical Code provides information with
respect 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
requirements for the grounding electrode.
(continued on the next page)

7 An outside antenna system should not be
located in the vicinity of overhead power
lines or other electric light or power
circuits, or where it can fall into such
power lines or circuits. When installing an
outside antenna system, extreme care
should be taken to keep from touching
such power lines or circuits as contact
with them might be fatal.

8 Appliances are provided with ventilation
openings in the cabinet to allow heat
generated during operation to be released.
Therefore:
– Never block the bottom ventilation slots
of a portable Appliance by placing it on
a bed, sofa, rug, etc.
– Never place an Appliance in a “built-in”
enclosure unless proper ventilation is
provided.
– Never cover the openings with a cloth
or other material.
– Never place the Appliance near or over
a radiator or heat register.
9 To avoid personal injury:
– Do not place an Appliance on a sloping
shelf unless properly secured.
– Use only a cart or stand recommended
by the Appliance manufacturer.
– Do not try to roll a cart with small
casters across thresholds or deep pile
carpets.
– Wall or shelf mounting should follow the
manufacturer’s instructions, and should
use a mounting kit approved by the
manufacturer.
USE
10 Caution children about dropping or
pushing objects into the Appliance through
cabinet openings. Some internal parts
carry hazardous voltages and contact can
result in a fire or electrical shock.
11 Unplug the Appliance from the wall outlet
before cleaning. Do not use liquid or an
aerosol cleaner.
12 Never add accessories to an Appliance
that has not been designed for this
purpose. Such additions may result in a
hazard.
13 For added protection of the Appliance
during a lightning storm or when the
Appliance is to be left unattended for an
extended period of time, unplug it from the
wall outlet and disconnect the antenna.
This will prevent damage to product due
to lightning storms or power line surges.

14 An Appliance and cart combination should
be moved with care. Quick stops, excessive
force, and uneven surfaces may cause the
Appliance and cart combination to overturn.
SERVICE
15 Unplug this Appliance from the wall outlet
and refer servicing to qualified service
personnel under the following conditions:
A.When the power cord or plug is
damaged or frayed.
B.If liquid has been spilled into the
Appliance.
C.If the Appliance has been exposed to
rain or water.
D.If the Appliance does not operate
normally by following the operating
instructions. Adjust only those controls
that are covered in the operating
instructions as improper adjustment of
other controls may result in damage
and will often require extensive work by
a qualified technician to restore the
Appliance to normal operation.
E.If the Appliance has been dropped or
damaged in any way.
F. When the Appliance exhibits a distinct
change in performance — this indicates
a need for service.
16 Do not attempt to service this Appliance
yourself as opening or removing covers
may expose you to dangerous voltage or
other hazards. Refer all servicing to
qualified service personnel.
17 When replacement parts are required,
have the service technician verify in
writing that the replacement parts he uses
have the same safety characteristics as
the original parts. Use of manufacturer’s
specified replacement parts can prevent
fire, shock, or other hazards.
18 Upon completion of any service or repairs
to this Appliance, please ask the service
technician to perform the safety check
described in the manufacturer’s service
literature.
19 When an Appliance reaches the end of its
useful life, improper disposal could result
in a picture tube implosion. Ask a qualified
service technician to dispose of the
Appliance.
20 Note to CATV system installer.
This reminder is provided to call the CATV
system installer’s attention to Article 82040 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.
SCREEN BURN
● Try to avoid displaying still images or extremely bright images on the screen for an extended
period of time. If left on screen for too long the image will be permanently etched onto the
CRT — a phenomenon known as “screen burn”. Screen burn is not a problem when
displaying moving pictures during video playback.
