causing serious injury to a child or adult, and serious
damage to the product. Use only with a cart, stand, tripod,
bracket, or table recommended by the manufacturer, or
sold with the product. Any mounting of the product should
follow the manufacturer’s instructions, and should use a
mounting accessory
recommended by the
manufacturer.

9. A product and cart

combination should be
moved with care. Quick
stops, excessive force,
and uneven surfaces may
cause the product and cart
combination to overturn.

10. Ventilation – Slots and openings in the cabinet are provided
for ventilation and to ensure reliable operation of the
product and to protect it from overheating, and these
openings must not be blocked or covered. The openings
should never be blocked by placing the product on a bed,

13. Power-Cord Protection – Power-supply cords should be
routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the
product.

15. Outdoor Antenna Grounding – If an outside antenna or
cable system is connected to the product, be sure the
antenna or cable system is grounded so as to provide
some protection against voltage surges and built-up static
charges. Article 810 of the National Electrical Code,
ANSI/NFPA 70, provides information with regard to proper
grounding of the mast and supporting structure, grounding
of the lead-in wire to an antenna discharge unit, size of
grounding conductors, location of antenna-discharge unit,
connection to grounding electrodes, and requirements for
the grounding electrode. See Figure A.

16. Lightning – For added protection for this product during a
lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet and
disconnect the antenna or cable system. This will prevent
damage to the product due to lightning and power-line
surges.

17. Power Lines – An outside antenna system should not be
located in the vicinity of overhead power lines or other
electric light or power circuits, or where it can fall into such
power lines or circuits. When installing an outside antenna
system, extreme care should be taken to keep from
touching such power lines or circuits as contact with them
might be fatal.

18. Overloading – Do not overload wall outlets, extension
cords, or integral convenience receptacles as this can
result in a risk of fire or electric shock.

19. Object and Liquid Entry – Never push objects of any kind
into this product through openings as they may touch
dangerous voltage points or short-out parts that could
result in a fire or electric shock. Never spill liquid of any
kind on the product.

20. Servicing – Do not attempt to service this product yourself
as opening or removing covers may expose you to
dangerous voltage or other hazards. Refer all servicing to
qualified service personnel.

21. Damage Requiring Service – Unplug this product from the
wall outlet and refer servicing to qualified service
personnel under the following conditions:
a) When the power-supply cord or plug is damaged,
b) If liquid has been spilled, or objects have fallen into the

product,
c) If the product has been exposed to rain or water,
d) If the product does not operate normally by following

the operating instructions. Adjust only those controls

that are covered by the operating instructions as an

improper adjustment of other controls may result in

damage and will often require extensive work by a

qualified technician to restore the product to its normal

operation,
e) If the product has been dropped or damaged in any

way, and
f) When the product exhibits a distinct change in

performance – this indicates a need for service.

22. Replacement Parts – When replacement parts are
required, be sure the service technician has used
replacement parts specified by the manufacturer or have
the same characteristics as the original part. Unauthorized
substitutions may result in fire, electric shock, or other
hazards.

23. Safety Check – Upon completion of any service or repairs
to this product, ask the service technician to perform
safety checks to determine that the product is in proper
operating condition.

24. Wall or Ceiling Mounting – The product should be mounted
to a wall or ceiling only as recommended by the
manufacturer.

25. Heat – The product should be situated away from heat
sources such as radiators, heat registers, stoves, or other
products (including amplifiers) that produce heat.

CONNECTIONS

Leave your entire system (including the DN-T645/625) turned off until all connections between the DN-T645/625
and other components have been completed.

2 Connection precautions

• Before proceeding with connections or disconnections of cables and power cords, be sure to turn all
system components off.

• Ensure that all cables are connected properly to the L (left) and R (right) jacks.

• Insert plugs fully into the terminals.

• Connect the CD output jacks to the amplifier CD or AUX input jacks.

The CD player uses a microcomputer for controlling
internal electronic circuits. In the event that the player
is used while a near-by tuner or TV is turned on,

I / O

although unlikely, interference could occur either in the
sound from the tuner or the picture of the TV. To avoid

I

this, please take the following precautions.

I

• Keep the CD player as far away from the tuner or TV
set as possible.

• Keep the power cable and connecting cable of the

I

CD player separate from the antenna wires of the
tuner and TV.

_

• Interference is particular likely to occur when an
indoor antenna or a 300 Ω/ohms feeder cable is

_

used. Thus, use of an outdoor antenna and 75
Ω/ohms coaxial cable is strongly recommended.

NOTE :

• Use this unit in a horizontal orientation.

PLAYING MP3 FILES (DN-T645

There are many sites on the Internet from which you can download music files in MP3 format. These files can
be downloaded following the instructions on the site and stored on CD-R/RW discs which can then be played on
the DN-T645.
The music on commercially available music CDs can be converted into MP3 files on a computer using MP3
encoding programs. When this is done, the data is reduced to approximately 1/10 the original size. This MP3 data
can then be stored on a CD-R/RW disc, allowing you to create a single 12 cm CD-R/RW disc containing about 10
times more music than a normal music CD, that is some 100 tracks or more (*).

* This is an approximately value for MP3 files of tracks about 5 minutes long converted at a standard bit rate

(128 kbps) and stored on a CD-R/RW disc with a capacity of 650 MB.

✽ Recordings you make are for your personal use and should not be used in ways infringing upon the copyright

holder as per copyright laws.

NOTES :

• The DN-T645 is compatible with “ MPEG-1 Audio
Layer-3” , “ MPEG-2 Audio Layer-3” and “ MPEG-

2.5 Audio Layer-3” . It is not compatible with MP1
or MP2 standards.

MPEG 1
MPEG 2
MPEG 2.5

• When writing MP3 files on a CD-R/RW disc, set
the writing program’s format to “ISO9660 level 1”
or “ ISO9660 level 2” , “ Joliet” or “ Romeo” . MP3
files written in other formats may not play
properly. With some writing programs it is not
possible to record in “ ISO9660” format. Use an
“ ISO9660” format writing program.

• Generally speaking, the higher the MP3 file’s bit
rate, the better the sound quality. With the DN­T645 it is recommended to use MP3 files written
with a bit rate of 128 kbps or greater.

• The writing program may change the positions of
the folders and files when writing the MP3 files
on the CD-R/RW disc, so the files may not be
played in the expected order.

• Make sure to give MP3 files the extension
“ .MP3” . Files with extensions other than “ .MP3”
or without extensions cannot be played. (On
Macintosh computers, MP3 files can be played by
adding the extension “ .MP3” after the file name
consisting of a maximum of 8 Roman capital
letters and / or numerals when recording them on
CD-R/RW discs.)

• To protect copyrights, no digital signals are output
when playing MP3 files.
