1.1 Important Safeguards
For Audio Products
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.
CAUTION: To prevent electric shock,
do not use this (polarized) plug with
an extension cord, receptacle or other outlet
unless the blades can be fully inserted to
prevent blade exposure.
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.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accor-
dance with the manufacturer's instructions.
8. Do not install near any heat sources such as radiators,
heat registers, stoves or other apparatus (including ampli-
fiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding-type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an elec-
trician for replacement of the obsolete outlet.
10. Protect the power cord from being
walked on or pinched, particularly at plugs,
convenience receptacles and the point
where they exit from the apparatus.
11. Only use attachments/accessories specified by the
12. Use only with the cart, stand, tripod, bracket or table
specified by the manufacturer or sold with the apparatus.
When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when
unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been dam-
aged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate nor-
mally, or has been dropped.
15. Do not use attachments not recommended by the
product manufacturer, as they may cause hazards.
16. This product 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 to your home, consult
your product dealer or local power company. For products
intended to operate from battery power, or other sources,
refer to the operating instructions.
17. If an outside antenna or cable system is connected to
the product, be sure the antenna or cable 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 informa-
tion with regard to proper grounding of the mast and sup-
porting structure, grounding of the lead-in wire to an anten-
na discharge unit, size of grounding conductors, location of
antenna-discharge unit, connection to grounding elec-
trodes, and requirements for the grounding electrode. See
Figure 1.
