SERVICING PRECAUTIONS
NOTES REGARDING HANDLING OF THE PICK-UP
1. Notes for transport and storage
1) The pick-up should always be left in its conductive bag until immediately prior to use.
2) The pick-up should never be subjected to external pressure or impact.
2. Repair notes
1) The pick-up incorporates a strong magnet, and so should never be brought close to magnetic materials.
2) The pick-up should always be handled correctly and carefully, taking care to avoid external pressure and
impact. If it is subjected to strong pressure or impact, the result may be an operational malfunction
and/or damage to the printed-circuit board.
3) Each and every pick-up is already individually adjusted to a high degree of precision, and for that reason
the adjustment point and installation
screws should absolutely never be touched.
4) Laser beams may damage the eyes!
Absolutely never permit laser beams to enter the eyes!
Also NEVER switch ON the power to the laser output part (lens, etc.) of the pick-up if it is damaged.
5) Cleaning the lens surface
If there is dust on the lens surface, the dust should be cleaned away by using an air bush (such as used
for camera lens). The lens is held by a delicate spring. When cleaning the lens surface, therefore, a cotton swab should be used, taking care not to distort this.
6) Never attempt to disassemble the pick-up.
Spring by excess pressure. If the lens is extremely dirty, apply isopropyl alcohol to the cotton swab. (Do
not use any other liquid cleaners, because they will damage the lens.) Take care not to use too much of
this alcohol on the swab, and do not allow the alcohol to get inside the pick-up.
Storage in conductive bag
NEVER look directly at the laser beam, and don’t let contact
fingers or other exposed skin.

NOTES REGARDING COMPACT DISC PLAYER REPAIRS
1. Preparations
1) Compact disc players incorporate a great many ICs as well as the pick-up (laser diode). These components are sensitive to, and easily affected by, static electricity. If such static electricity is high voltage,
components can be damaged, and for that reason components should be handled with care.
2) The pick-up is composed of many optical components and other high-precision components. Care must
be taken, therefore, to avoid repair or storage where the temperature of humidity is high, where strong
magnetism is present, or where there is excessive dust.
2. Notes for repair
1) Before replacing a component part, first disconnect the power supply lead wire from the unit
2) All equipment, measuring instruments and tools must be grounded.
3) The workbench should be covered with a conductive sheet and grounded.
When removing the laser pick-up from its conductive bag, do not place the pick-up on the bag. (This is
because there is the possibility of damage by static electricity.)
4) To prevent AC leakage, the metal part of the soldering iron should be grounded.
5) Workers should be grounded by an armband (1MΩ)
6) Care should be taken not to permit the laser pick-up to come in contact with clothing, in order to prevent
static electricity changes in the clothing to escape from the armband.
7) The laser beam from the pick-up should NEVER be directly facing the eyes or bare skin.

ESD PRECAUTIONS
Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques should
be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off
any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a
commercially available discharging wrist strap device, which should be removed for potential shock reasons
prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static"
can generate electrical charges sufficient to damage ESD devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESD
devices.
6. Do not remove a replacement ESD device from its protective package until immediately before you are
ready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together by
conductive foam, aluminum foil or comparable conductive materials).
7. Immediately before removing the protective material from the leads of a replacement ESD device, touch the
protective material to the chassis or circuit assembly into which the device will by installed.
CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL
OTHER SAFETY PRECAUTIONS.
8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motion
such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ESD device).

Important Note: To prevent possible damage
to your speakers or other components in your
audio system, we strongly recommend that ALL
system components,including the CDR 30,be
turned off and unplugged from their AC power
source when any connections are made or a
new component is installed.
Locating the CDR 30
Since the CD transports in the CDR 30 are precision instruments,they are subject to interference from vibration.To minimize the possibility
of skipping during playback or recording, it is
recommended that the unit be placed on a
level, solid, vibration-free surface.
When installing the CDR 30 in a cabinet or
tight space,always make certain that there is
enough room in front of the unit for the disc
drawers to open fully,and that there is enough
space above the unit so that discs may easily
be inserted in the disc drawers.
In addition to the safety considerations outlined
on page 4, it is also recommended that the
CDR 30 not be placed in a location that is subject to direct sunlight or extreme heat or cold,
as these conditions may damage the discs used
in the player, or the player itself. Note that
audio amplifiers or high-power receivers,as
well as certain other electronic products,may
generate significant heat.For that reason,do
not place the CDR 30 directly on top of an
amplifier, receiver, or other heat source.Always
allow at least one inch of free space on all
sides of the CDR 30, as well as other electronic
products,to allow for proper ventilation.
The unit should also be kept away from sources
of water or damp conditions.
Connections to Your Audio System
When connecting the CDR 30, think of the
process as if your were connecting a standard
CD player and a tape or cassette recorder, with
the addition of the digital connections.
Play-Deck Connections
The rear panel connections labeled “CDP”refer
to the outputs of the Play Deck 3, which
functions as a standard CD player. Connect the
analog left/right CDP Outputs ¡ to the CD
inputs on your receiver, preamp or surround
processor. For best playback results, a digital
connection is recommended, using the Coaxial
¢ or Optical ª Outputs. Connect them to
the matching digital inputs of your receiver, preamp,processor or external digital decoder. Note
that you may have to change a setting on the
receiver or processor to link the digital input to
the “CD”button or input selector. Consult the
owner’s manual on that device for details, as
this configuration may vary from unit to unit.
Record-Deck Connections
The rear panel connections labeled “CDR”refer
to the inputs and outputs for the Record Deck
%. Depending on the capabilities of your
receiver, preamp or processor, you may find it
convenient to connect the analog inputs and
outputs to the jacks marked for a tape recorder.
As the CDR 30’s functions resemble those of
a standard tape recorder, this might make it
easier to select it as an input on your receiver
or preamp.Connect the analog CDR-Out
Jacks ™ to the Play/In jacks of a Tape or Aux
input on your receiver or preamp.Connect the
CDR-In Jacks £ to the Tape Rec/Out jacks on
your receiver or preamp.
To play the output of the Record Deck through
the digital decoder in your receiver or an external processor, connect the CDR Coaxial ∞ or
Optical • digital outputs jacks to the matching
digital-input jacks on your receiver or processor.
Note that you may have to change a setting on
the receiver or processor to link the digital
input to the “Tape” button or the specific input
selector associated with the digital inputs.
Consult the owner’s manual on your receiver or
processor for details,as this configuration may
vary from unit to unit.
To make recordings from external digital
sources,such as a CD,DVD or MD player, connect the CDR Coax-In Jacks §& or CDR
Optical-In Jacks ¶^ on the CDR to the
digital output jacks on your receiver or processor. If your receiver does not have digital-output
jacks,you may connect the CDR Coax-In
Jacks §& or CDR Optical-In Jacks ¶^
on the CDR 30 directly to the digital outputs on
your CD player or other digital device.
Connections to a portable digital CD or MD
player may also be made by connecting the
Coax Digital Output of the player to the front
panel Digital Input Jacks ^& on the
CDR 30. Note that when both the front and
rear panel digital inputs are connected to
external sources,the CDR 30 will give priority
to the front panel input. If it is impractical to
disconnect the front panel input when you need
to use the rear panel jack, simply turn off the
device connected to the front panel input.This
will stop the digital signal, and permit the rear
panel jack to be used.
IMPORTANT NOTES ON DIGITAL
CONNECTIONS:
Although digital-coax connections use the same
type of “RCA” phono jack as standard analog
signals,please take special care to connect digital signals only to digital jacks.In many cases,
the digital jacks may be identified by an
orange-colored insert ring around the center of
the jack.When making digital connections, be
sure to use coax-interconnect cables,such as
the one supplied with the CDR 30 or cables
intended for video applications.Even though
they have the correct type of RCA connector, do
not use audio-interconnect cables that have
twisted-pair construction, as they are not
appropriate for digital signal use.If you have
any questions about the type of cables to use
with the CDR 30, consult your dealer.
Installation and Connections

Installation and Connections
Batteries
Insert the two AA batteries supplied with the
CDR 30’s remote by turning the remote over so
that the bottom of the remote is facing towards
you. Gently lift the plastic tab on the battery
cover up and away from you,and lift the lid off.
Insert the batteries in the remote,being careful
to follow the + and – polarity indications in the
bottom of the compartment. Replace the cover
by first seating the two small tabs into the mating holes at the top of the remote,and then
gently push the cover down until the latch
snaps into place with an audible click.
NOTE:When replacing batteries, it always a
good idea to replace both at the same time.
When the remote will not be used for an
extended period of time,it is also a good idea
to remove the batteries to avoid the possibility
of damage due to corrosion. Batteries contain
chemical substances and we recommend that
you dispose of them properly and in compliance
with any local regulations.
IR Remote Connections
If the CDR 30 is installed behind a cabinet or
other obstruction that may block the path
between the front panel Remote Sensor ¯
and the location where you will use the remote,
an optional external IR sensor may be used.
Connect the sensor to the Remote IR In Jack
‚ on the rear panel. This jack may also be
connected to the IR Output jack of another
compatible Harman Kardon component or a
compatible IR system remote product.
You may also use the IR Sensor in the CDR 30
to send commands to other compatible remote
products.Connect the Remote IR Out Jack
⁄ to the input of the other product or system.
Power Connections
Connect the AC Power Cord¤ to an AC
power source.The CDR 30 uses sensitive,highperformance computer-grade CD drives, and to
protect them we recommend that you consider
the use of a surge protector, just as you would
for a computer.
If the rear panel AC outlet on a receiver or
other product is used, make certain that it
provides at least 28 watts,and that the total
power of all products connected does not
exceed the maximum rated output of the product containing the outlets.If the CDR 30 is connected to a switched outlet, remember to turn
on the outlet or product controlling it in order
for the CDR 30 to operate.

Notice - Important information regarding the use of the harman/kardon CDR 30.
1) Complaint: “I cannot record at x2 or x4 speed. Unit switched back to 1x speed”
Possibl e explanations:
a) Programmed play only records at x1 speed. You cannot record at x2 or x4 speeds when programmed
dub is attempted (to record only certain tracks on a CD)
b) S ome brands of CDR do not allow recording at x2 or x4 speed. Try another major brand – Maxell,
Memorex, Sony,TDK. See list below.
c) Disc might be a copy - even a counterfeit disc – this will prevent reco rding at speeds greater than 1X.
Try recording off a new store-bought CD you know
2) Due to slight variations in the manufacture of blank CD-R/RW audio discs, and for optimum
performance of your CD recorder, harman/kardon recommends that you use blank recording
discs manufactured by the following companies:
Products from these brand s ha ve been tested and certified for use with the CDR 30. While discs from other
brands may also work, we cannot guarantee proper operation of the unit when they are used.
Recommended CD-R Audio Disc Manufacturers:
TDK Electronics Corporation Maxell Corporation of America
LG Electronics, Inc. Mitsubishi Electric & Electronics USA, Inc.
Ricoh Co mpany, Ltd. Philips Electronics North America
Memorex Axia
Recommended CD-RW Audio Disc Manufacturers:
TDK Electronics Corporation Fuji Photo Film, U.S.A., Inc.
LG Electroni cs , I nc. Memorex
Phili ps Elec tronics North America Samsung Electron i cs Co., Ltd.
Ricoh Co mpany, Ltd. Axia
SANYO-Verbatim CD Company SKC America, Inc.
ZeroOne Mitsubishi Electric & Electronics USA, In c
Maxell Corporation of America
NOTE: The names shown a bove are the primary manufacturers, who may also produce discs for other brand
names. When in doubt as to the origin of a disc, check with the brand shown on the package.
3) When a CD Audio disc is recorded on a computer, it is often possible to record a set of tracks,
finalize the disc, and then add additional tracks and finalize the disc again in a second recording
session. This produces what is called a “multi-session” disc. Please note that these discs will work
properly when played back on a computer, or on the CDR 30’s Record (CDR) deck. However, due to
differences in the way CDs are played back on computers, as opposed to consumer CD Audio players,
multi-session discs will NOT play back prope rly on the CDR 30’s P lay (CDP) de c k, o r on most consumer
CD players. When a multi-session disc is played in the CDP deck, only the tracks in the first session will
play. This is not a defect or problem with the CDR 30, but is due to differen ces in the formats be t ween
computer recordings and CD Audio products or commercially recorded CDs.
4) The CDR 30 prohibits the track incrementing function during the first six seconds for each track
during recording. Thus, if a source track is less than six seconds long, it will be recorded, but it will not be
assigned a track number. The track with less than six seconds will be combined into the next track number
that is recorded on the disc. This feature prevents the recording of empty tracks when the source signal
was not cued up to start playing at the same time a recording session begins.
