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,
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 short­out 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.
