IMPORTANT - THE PRODUCT REQUIRES
CLASS 2 OUTPUT WIRING
TO PREVENT ELECTRIC SHOCK, DO NOT REMOVE TOP
OR BOTTOM COVERS. NO USER SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.
DISCONNECT POWER CORD BEFORE REMOVING REAR
PANEL COVER TO ACCESS GAIN SWITCH.
TO REDUCE THE RISK OF ELECTRIC
SHOCK, DO NOT EXPOSE THIS
EQUIPMENT TO RAIN OR MOISTURE!
CAUTION Do not locate sensitive high-gain
equipment such as preamplifiers or tape decks
directly above or below this unit. Because this
amplifier has a high power density, it has a
strong magnetic field which can induce hum into
unshielded devices that are located nearby. This
field is strongest just above and below the unit.
If an equipment rack is used, we recommend
locating the amplifier(s) at the bottom of the
rack and the preamplifier or other sensitive
equipment at the top.
Do not use this apparatus near water. Clean only with
a damp cloth.
4. The apparatus must be connected to a mains socket
outlet with a protective earthing connection.
5. The appliance coupler must remain readily operable
for disconnection from the mains.
6. Do not block any of the ventilation openings. Install
in accordance with the manufacturer’s instructions.
7. Do not install near any heat sources such as
radiators, heat registers, stoves, or other apparatus
that produce heat.
8. Do not install the safety purpose of a 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 third grounding plug. The wide
blade or the third prong is provided for your safety.
When the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete
outlet.
9. Protect the power cord from being walked on or
pinched, particularly at plugs, convenience at plugs,
convenience receptacles, and the point where they exit
from the apparatus.
10. Only use power cord from attachments/accessories
specified by the manufacturer.
11. Use only with a cart, stand, 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 flip-over.
13. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged 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, or does not operate
normally.
Please follow the instructions in this manual to
obtain the optimum results from this unit. We also
recommend that you keep this manual handy for
future reference.
