Introduction and Safety Information
Important Information
for the User
Note: 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. The 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
communication. However, there is no
guarantee that harmful interference will
not occur in a particular installation. If
this equipment does cause harmful inter-
ference to radio or television reception,
which can be determined by tuning the
equipment off and on, the user is encour-
aged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving
antenna.
• Increase the separation between this
unit and the receiver being interfered
with.
• Connect this unit 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.
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 interference
received, including interference that may
cause undesired operation.
Note: Changes or modifications may
cause this unit to fail to comply with Part
15 of the FCC Rules and may void the
user’s authority to operate the equip-
ment.
Unpacking and Installation
The carton and shipping materials used
to protect your new DC520 during ship-
ment were specially designed to cushion
it from shock and vibration. We suggest
that you save the carton and packing
materials for use in shipping if you move
or should the unit ever need repair.
To minimize the size of the carton in
storage, you may wish to flatten it. This
is done by carefully slitting the tape
seams on the bottom and collapsing the
carton down to a more two dimensional
appearance. Other cardboard inserts may
be stored in the same manner. Packing
materials that cannot be collapsed
should be saved along with the carton in
a plastic bag.
If you do not wish to save the packaging
materials, please note that the carton
and other sections of the shipping protec-
tion are recyclable. Please respect the
environment and discard those materials
at a local recycling center.
When positioning your DC520 in its final
location, make certain that any shelf or
stand is capable of supporting it’s weight,
and that there is adequate ventilation on
all sides, as well as on the top and bot-
tom. Do not place CDs, record jackets,
owner’s manuals, or other paper on top
of, or beneath the unit. This will block
air flow and create a potential fire haz-
ard. If the unit is to be enclosed in a cab-
inet or rack, make certain that there is
adequate air circulation, with a means
provided for hot air to exit, and for cool
air to be brought in.
