7.

Water and Moisture - Do not use this unit near water - for example, near a
bath tub, wash bowl, kitchen sink, or laundry tub, in a wet basement, near
a swimming pool, in an unprotected outdoor installation, or 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 - Openings in the enclosure, if any, are provided for ventilation
and to ensure reliable operation of the unit and to protect it from
overheating. These openings must not be blocked or covered. This unit
should not be placed in a built-in installation unless proper ventilation is
provided or the manufacturer's instructions have been adhered to.

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 appliance 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 3-wire 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 rain or water.

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.70-1981, 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.
