Important Safeguards
1. Read Instructions - All safety and operating
instructions should be read before the unit is
operated.
2.Retain Instructions - The safety and operating
instructions 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 use
instructions should be followed.
5.Cleaning - Unplug the unit from the outlet before
cleaning. Do not use liquid cleaners or aerosol
cleaners. Use a damp cloth for cleaning.
6.Attachments - Do not use attachments not
recommended by the product manufacturer as they
may cause hazards.
7. Water and Moisture - Do not use this unit near
water - for example, in a wet basement, near a
swimming pool, in an unprotected outdoor
installation, or in any area which is classified as a
wet location.
8.Accessories - Do not place this unit on an unstable
stand, tripod, bracket, or mount. The unit may fall,
causing serious injury to a person and serious
damage to the unit. Use only with a stand, tripod,
bracket, or mount recommended by the
manufacturer or sold with the product. Any
mounting of the unit should follow the
manufacturer's instructions and should use a
mounting accessory recommended by the
manufacturer.
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.
9.Ventilation - This unit should not be placed in a
built-in installation or rack, unless proper
ventilation is provided, or the manufacturer’s
instructions have been adhered to. The equipment
must not exceed its maximum operating
temperature requirements.
10.Power Sources - This unit should be operated only
from the type of power source indicated on the
marking label. If you are not sure of the type of
power supply you plan to use, consult your dealer
or local power company. For units intended to
operate from battery power or other sources, refer
to the operating instructions.
11. Grounding or Polarization - This unit may be
equipped with a polarized alternating-current line
plug (a plug having one blade wider than the
other). This plug will fit into the power outlet only
one way. This is a safety feature. If you are unable
to insert the plug fully into the outlet, try reversing
the plug. If the plug should still fail to fit, contact
your electrician to replace your obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
Alternately, this unit may be equipped with a 3wire grounding-type plug, a plug having a third
(grounding) pin. This plug will only fit into a
grounding-type power outlet. This is a safety
feature. If you are unable to insert the plug into the
outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the safety purpose of
the grounding-type plug.
12.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 and plugs,
convenience receptacles, and the point where they
exit from the appliance.
13.Power Lines - An outdoor 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 outdoor system, extreme care should
be taken to keep from touching such power lines or
circuits as contact with them might be fatal. U.S.A.
models only - refer to the National Electrical Code
Article 820 regarding installation of CATV systems.
14.Overloading - Do not overload outlets and
extension cords as this can result in a risk of fire or
electric shock.
15. Object and Liquid Entry - Never push objects of
any kind into this unit through openings, as they
may touch dangerous voltage points or short out
parts that could result in a fire or electric shock.
Never spill liquid of any kind on the unit.
16.Servicing - Do not attempt to service this unit
yourself as opening or removing covers may expose
you to dangerous voltage or other hazards. Refer all
servicing to qualified service personnel.

17. Damage Requiring Service - Unplug the unit from
the outlet and refer servicing to qualified service
personnel under the following conditions:
a. When the power supply cord or plug is
damaged.
b. If liquid has been spilled or objects have fallen
into the unit.
c. If the unit has been exposed to water and/or
inclement weather (rain, snow, etc.).
d. If the unit does not operate normally by
following the operating instructions. Adjust only
those controls that are covered by the operating
instructions, as an improper adjustment of other
controls may result in damage and will often
require extensive work by a qualified technician
to restore the unit to its normal operation.
e. If the unit has been dropped or the cabinet has
been damaged.
f. When the unit exhibits a distinct change in
performance--this indicates a need for service.
18.Replacement Parts - When replacement parts are
required, be sure the service technician has used
replacement parts specified by the manufacturer
or have the same characteristics as the original
part. Unauthorized substitutions may result in fire,
electric shock, or other hazards.
19. Safety Check - Upon completion of any service or
repairs to this unit, ask the service technician to
perform safety checks to determine that the unit is
in proper operating condition.
20.Coax Grounding - If an outside cable system is
connected to the unit, be sure the cable system is
grounded. U.S.A. models only--Section 810 of the
National Electrical Code, ANSI/NFPA No.70,
provides information with respect to proper
grounding of the mount and supporting structure,
grounding of the coax to a discharge unit, size of
grounding conductors, location of discharge unit,
connection to grounding electrodes, and
requirements for the grounding electrode.
21. Lightning - For added protection of this unit during
a lightning storm, or when it is left unattended and
unused for long periods of time, unplug it from the
wall outlet and disconnect the cable system. This
will prevent damage to the unit due to lightning
and power line surges.

Safety Precautions
Attention: Installation should be performed by
qualified service personnel only in accordance
with the National Electrical Code or applicable
local codes.
Power Disconnect. Units with or without ONOFF switches have power supplied to the unit
whenever the power cord is inserted into the
power source; however, the unit is operational
only when the ON-OFF switch is in the ON
position. The power cord is the main power
disconnect for all units.
CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE COVER
(OR BACK). NO USER SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.
The lightning flash with an 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 presence of important
operating and maintenance (servicing)
instructions in the literature
accompanying the appliance.
Sécurité
Attention : L’installation doit être exclusivement
effectuée par un technicien spécialisé
conformément à la réglementation du code
national de l’électricité des États-Unis (NEC) ou à
la réglementation locale.
Coupure de l’alimentation. Les appareils avec ou
sans commutateur ON-OFF (marche-arrêt) sont
alimentés dès que le cordon d’alimentation est
branché à la source d’alimentation ; toutefois, les
appareils disposant d’un commutateur de
marche-arrêt ne fonctionnent que lorsque celui-ci
est sur la position ON (marche). Le cordon
d’alimentation est l’organe de coupure principal
de l’alimentation pour tous les appareils.
ATTENTION : POUR ÉVITER TOUT RISQUE
D’ÉLECTROCUTION, NE PAS OUVRIR LE
BOÎTIER. IL N’Y A PAS DE PIÈCES
REMPLAÇABLES À L’INTÉRIEUR. POUR
TOUTE INTERVENTION, S’ADRESSER À UN
RÉPARATEUR PROFESSIONNEL COMPÉTENT.
L’éclair fléché dans un triangle équilatéral
avertit l’utilisateur de la présence d’une
« tension dangereuse » non isolée à
l’intérieur de l’appareil et d’une valeur
suffisante pour constituer un risque
d’électrocution.
Le point d’exclamation contenu dans un
triangle équilatéral avertit l’utilisateur de
la présence, dans la documentation qui
accompagne l’appareil, d’importantes
consignes d’utilisation et de maintenance.
