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.  
4) Follow all instructions.  
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

6) Clean only with dry cloth.  
7) Do not block any ventilation openings. Install in accordance with  
the manufacturer’s instructions.  
13) Unplug this apparatus during lightning storms or when unused  
for long periods of time.  
8) Do not install near any heat sources such as radiators, heat  
registers, stoves, or other apparatus (including amplifiers) that  
produce heat.  
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.  
9) Do not defeat the safety purpose of the polarized or grounding-

for your safety. If the provided plug does not fit into your outlet,  
consult an electrician for replacement of the obsolete outlet.  
THE FOLLOWING APPLIES ONLY IN THE U.S.A.:  
Listening caution  
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 inter-  
ference will not occur in a particular installation. If this equip-  
ment does cause harmful interference to radio or television  
reception, which can be determined by turning the equip-  
ment off and on, the user is encouraged to try to correct the  
interference by one or more of the following measures:  
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.  
Reorient or relocate the receiving antenna.  
Increase the separation between the equipment and re-  
We recommend that you avoid prolonged exposure to excessive  
noise.  
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.  
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.  
Any unauthorized changes or modifications to this equipment  
would void the user’s authority to operate this device.  
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.  
This device complies with Part 15 of the FCC Rules. Opera-  
tion 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.  
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.
