IMPORTANT SAFETY INSTRUCTIONS

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.

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 grounding­type 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.

Listening caution

Selecting fine audio equipment such as the unit you’ve just pur­chased is only the start of your musical enjoyment. Now it’s time to
consider how you can maximize the fun and excitement your equip­ment offers. This manufacturer and the Electronic Industries Associ­ation’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.

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.

THE FOLLOWING APPLIES ONLY IN THE U.S.A.:

CAUTION:

This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules.
These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However, there is no guarantee that inter­ference will not occur in a particular installation. If this equip­ment does cause harmful interference to radio or television
reception, which can be determined by turning the equip­ment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

•

Increase the separation between the equipment and re-

•

ceiver.
Connect the equipment into an outlet on a circuit different

•

from that to which the receiver is connected.
Consult the dealer or an experienced radio/ TV technician

•

for help.

Any unauthorized changes or modifications to this equipment
would void the user’s authority to operate this device.

This device complies with Part 15 of the FCC Rules. Opera­tion is subject to the following two conditions: (1) This device
may not cause harmful interference, and (2) this device must
accept any interference received, including interference that
may cause undesired operation.
