Read these operating instructions carefully before using the unit. Follow the safety instructions on the unit and the applicable safety instructions
listed below. Keep these operating instructions handy for future reference.
Selecting fine audio equipment such as the unit you’ve just pur-
chased is only the start of your musical enjoyment. Now it’s time to
consider how you can maximize the fun and excitement your equip-
ment offers. This manufacturer and the Electronic Industries Associ-
ation’s Consumer Electronics Group want you to get the most out of
your equipment by playing it at a safe level. One that lets the sound
come through loud and clear without annoying blaring or
distortion—and, most importantly, without affecting your sensitive
hearing.
We recommend that you avoid prolonged exposure to excessive
noise.
Sound can be deceiving. Over time your hearing “comfort level”
adapts to higher volumes of sound. So what sounds “normal” can
actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level BEFORE
your hearing adapts.
To establish a safe level:
•Start your volume control at a low setting.
•Slowly increase the sound until you can hear it comfortably and
clearly, and without distortion.
Once you have established a comfortable sound level:
•Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage
or loss in the future. After all, we want you listening for a lifetime. 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 dry cloth.
7) Do not block any ventilation openings. Install in accordance with
the manufacturer’s instructions.
8) Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) 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 electrician 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 manufacturer.
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 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.
Listening caution
1. Damage requiring service—The unit should be serviced by
qualified service personnel if:
(a) The AC power supply cord or AC adaptor has been damaged; or
(b)Objects or liquids have gotten into the unit; or
(c) The unit has been exposed to rain; or
(d)The unit does not operate normally or exhibits a marked change
in performance; or
(e)The unit has been dropped or the cabinet damaged.
2. Servicing—Do not attempt to service the unit beyond that
described in these operating instructions. Refer all other servicing
to authorized servicing personnel.
3. Replacement parts—When parts need replacing ensure the
servicer uses parts specified by the manufacturer or parts that
have the same characteristics as the original parts. Unauthorized
substitutes may result in fire, electric shock, or other hazards.
