6) Clean only with a dry cloth.
7) Do not block any ventilation openings. Install
in accordance with the manufacturer s instr uctions.
8) Do not install near any heat sources such as
radiators, stoves, or other apparatus that
produce heat.
9) Do not defeat the safety purpose of the polari zed 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 is provided for your safety. If the
provided plug does not fit into your outlet,
consult an electrician for replacement of the
obsolete outlet.
10) Protect the power cable from being walked on
or pinched, particularly at plugs,and the point
where they exit from the apparatus.
11) Only use attachments/accessories specified
by the manufacturer.
12) 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 tip-over.
13) Unplug this apparatus during lightning storms
or when unused for long periods of time.
14) Refer all servicing to qualified service perso nnel.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, does not operate normally,
or has been dropped.
15) To reduce the risk of fire or electric shock, do
not expose this apparatus to rain or moisture.
TO PREVENT ELECTRIC SHOCK DO NOT REMOVE TOP OR BOTTOM COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL.
MAGNETIC FIELD
CAUTION! Do not locate sensitive highgain equipment such as
preamplifiers or tape decks dirctly above or below the 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. The field is strongest just aboveand below the unit.
If an equipment rack is used, we recommend locating the amplifier(s) in the bottom of the rack and the preamplifier or other
sensitive equipment at the top.
WATCH FOR THESE SYMBOLS:
The exclamation point triangle is used to alert the user to important operating or maintenance instructions.
The lightning bolt triangle is used to alert the user to the risk of
electric shock.
