LASER BEAM SAFETY PRECAUTIONS
CLASS 1 LASER PRODUCT
CAUTION
Invisible laser radiation when the unit is open.
Do not stare into beam.
CAUTION: USE OF ANY CONTROLS, ADJUSTMENT, OR
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN
MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
Do not look directly at the laser beam
coming from the pickup or allow it to
strike against your skin.
This compact disc player uses a pickup that emits a laser beam. The laser beam is emitted from the
location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 1 foot away
from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
CAUTION:
Using controls and adjustment, or doing procedures other than those specified herein, may result in
hazardous radiation exposure.

SAFETY PRECAUTIONS
This symbol is intended to alert the user to
the presence of uninsulated "dangerous
voltage" within the product's enclosure that
may be of sufficient magnitude to constitute a risk of electric shock to persons.
This symbol is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
Caution:To prevent electric shock do not use this
(polarized) plug with an extension cord, receptacle or other outlet unless the blades can be
fully inserted to prevent blade exposure.
Attention: Pour prevenir les chocs electriques ne pas
utiliser cetre fiche polarisee avec un
prolongateur, une prise de courant ou une autre sortie de courant, sauf si les lames prevent
etre inserees a fond-sans en laisser aucune
partie a decouvert.
HANDLING LASER PICKUP
The laser diode in the optical system of this player can be damaged by electrostatic discharge from
your clothes or your body. Proper electrostatic grounding for service personal is required during servicing.
BEFORE REPAIRING THE COMPACT DISC PLAYER
Preparation
Human Body Grounding:
Many of the components used in this compact disc player, including the laser pickup, are sensitive to
electrostatic discharge. Service personal should be grounded with an electrostatic armband (1 Mohm).
Caution:
Static charge on clothing does not escape through a body grounding wrist band.
Be careful not to contact the pickup or electrical components with your clothing.
Workbench and Tool Grounding:
A properly-grounded electroconductive plate (1Mohm) or metal sheet should be fitted to the workbench
surface. Tools and instruments (such as soldering irons and scopes) should be grounded to prevent AC
leakage.
Note: Laser diodes are so susceptible to damage from static electricity that, even if a static discharge does
not ruin a diode, it can shorten its life or cause it to work improperly.
WARNING
To prevent fire or shock hazard, do not
expose the unit to rain or moisture.

CDR 2 Important Notes – including issues th at may be
confused with “defects” when they are part of normal
operation
1. ALWAYS remove all discs before moving or repacking the unit! Since the
discs are not seated on a spindle, they have a tendency to slip out of the
trays. At best, the top cover needs to be removed in order to retrieve the
discs. At worst, loose discs inside the chassis can damage delicate
optical parts.
2. DO NOT STARE INTO THE LASER BEAM.
3. Although coaxial digital jacks may look the same as analog RCA jacks,
they are connected to different circuitry which is designed to process a
different type of signal. Do not connect coaxial digital jacks to analog RCA
jacks, and do not use audio interconnects that use twisted pair
construction for coaxial digital connections.
4. All optical connectors are not the same. Make sure to use only “TOS”
type connectors, which will audibly click when fully inserted into the jack.
Remember to save the plastic dust cap for the optical jack, and replace it
when the jack is not in use.
5. When playing CDs in Single mode, the audio signal will be routed to all
output jacks, regardless of which deck of the CDR 2 is playing.
6. The CDR 2 will only record on AUDIO CD-R and CD-RW discs. Only
use discs that bear the “Compact Disc Digital Audio Recordable” or
“Compact Disc Digital Audio ReWritable” logo. The packaging for these
discs should specify that they are intended for use in consumer CD audio
recorders.
7. The CDR 2 will NOT record on discs designed for use in computer CD-R
or CD-RW drives.
8. If a computer CD-R or CD-RW disc has been previously recorded on in a
computer drive and properly finalized in accordance with audio standard
IEC958, it can be played in the CDR 2. However, the CDR 2 will not
erase and record over a computer CD-RW disc.
9. In order to remove a program list, you must either turn the unit off or
remove the disc (or open the drawer so that the CDR 2 thinks you have
removed the disc).
10. Lower the volume when dubbing at high speed. You will be able to hear
the playback, and the higher pitch of the sound at high volumes may
cause damage to your speakers.
11. A program list may only be dubbed at 1x speed. If you attempt to dub at a
higher speed, the CDR 2 will automatically switch to 1x speed.
12. The CDR 2 is equipped with the Serial Copying Management System
(SCMS). This means that you cannot make a digital copy of a digital copy
of a disc; you can only make an analog copy of the first digital copy. If the
disc you are trying to dub is itself a digital copy, or if it contains copy
prohibit signals, the CDR 2 will automatically switch to analog mode. This
will be indicated in the front panel display.
13. The record level control only works in analog mode. If you find the level
control is having an effect on the recording, then the CDR 2 switched into
CDR2 harman/kardon
5
analog mode to dub that particular disc. When recording in analog mode,
make sure to use the level control to properly adjust the recording level.
14. In digital mode, if the CDR 2 senses a pause in the signal of more than 3
seconds, it will assume the recording session has ended and stop
recording. This means that if, for example, you program a set of tracks
from different discs on an external CD changer for recording, you may find
that the CDR 2 stops recording after each disc. The CDR 2 is sensing a
delay of more than three seconds while the CD changer switches to a
different disc, and this causes the CDR 2 to end the recording session.
Simply record tracks from one disc at a time on the external changer.
15. In analog mode, the CDR 2 will stop recording after a pause lasting for 10
seconds. If you have pressed the Auto/Manual button to place the unit in
Auto mode, it will increment the track number when it senses a 3 second
pause. In Manual mode, you must increment the track number manually
by pressing either the Track Increment or Next button.
16. The CDR 2 has a convenient front panel digital input for use in recording
from external sources, such as a portable CD player. Since it can only
record from one input at a time, if the CDR 2 senses a signal at both the
front and rear panel inputs, it will automatically record only from the front
panel input.
17. Tracks on a CD-RW disc that has been unfinalized may only be erased in
reverse sequential order. This means that you cannot erase a track in the
beginning or middle of the disc until all of the tracks after it have also been
erased.
18. Unfinalized discs will only play in the record deck, not the play deck.
19. In dual mode, only the output of the play deck will go to headphones.
20. Except when dubbing, make sure to press the Input button to select the
correct source. This is necessary whenever you are recording or using
the CD Sync function with an external source.
21. The pause button will not work while dubbing.
22. The CD Sync feature requires a digital input. Sync recordings may not be
made from an analog source.
For complaint: "CR2 defaults back to X1 speed when attempting a
recording at X4 speed" :
Normal conditions -
1) Will occur when an external input is selected.
2) Will occur when dubbing from a copied CD. (automatically goes into
analog recording)
3) Will occur when dubbing from a copy protected CD. (automatically goes
into analog recording)
4) Will occur when dubbing a programmed play list.
5) Certain CDR disc brands may only copy at X1 speed. Try another brand.

Service bulletin # H/K2000-08 Rev3 – September 2005
To: All harman/kardon Service Centers
Models: CDR2
Subject: Complain ts Related To Early Software
In the event you receive a CDR2 with one or more of the symptoms listed below, an upgrade in the
software may be necessary. Confirmation may be made by checking the serial numbers listed below.
1) When dubbing from the CDP deck, the unit randomly skips some of the tracks during the recording process
2) Audio drop out every 15-30 seconds, for less than a second each time, using the analog CDR outputs while
playing a disc in the CDP deck
3) Analog outputs of both wells have glitching/skipping sounds, but when monitored via headphones the sound
is normal
4) Intermittent Recording
5) CDs played on CDP deck have wow & flutter. Wow characterized by a slight hesitation in the sound and
flutter as a rapid fluttering sound
6) CDR deck durin g the reco rding process "chopping off" (truncating) the first few seconds of each track using
digital inputs
7) W ill not SYNCH record with MD player digital connections
8) W ill not SYNCH record with DVD pla y er connections
9) CDR deck when played as normal CD output mutes randomly
10) Switches to norma l (x1) dubbing speed even though x2 or x4 had been selected
11) Jumps to another part of the track dubbing at x4 speed
12) Low music input causes the unit to skip to the next track during recording
13) CDR deck during th e recording process does not automatically set track increments

harman/kardonTECH TIPS
Troubleshooting tips and solutions to common service problems
For model: CDR2TIP# HKTT2001-02 Rev1
Issue: Power Failure During A Recording Session
Power loss is defined as: CDR2 was switched OFF by the POWER button on the front panel, or by the OFF
button on the remote control, or through a power failure.
Circumstance #1
Power loss during the actual recording process
Symptom:
Attempts to read the disc in the Record drawer now produces an ERROR message in the display.
Solution:
Unfortunately, the disc is ruined and there is no way to retrieve this information. When you record a track, the
CDR2 updates the information on the disc so that it can read it even though the disc has not been finalized.
By turning off the unit while recording is in process, the unit never had the opportunity to update the disc. As
a result, the disc is no longer useable.
Circumstance #2
Power loss after the recording process took place, but before finalizing
Symptom:
A CDR with recordings will not finalize after the Finalize and Play/Select select buttons on the remote control
are pressed. Instead, when these buttons are pressed, the CDR (or a CD in the Play drawer) begins to Play -
not Finalize. (However, when the Finalize and Play/Select buttons on the front panel are used, the CDR2 will
finalize the CDR with recordings properly).
Solution:
After turning the CDR2 on, and the unit has read the information from both drawers, press the CDR button on
the remote control and follow the owner’s manuals’ instructions to complete the finalization process.
This problem will not occur when the recording and finalizing "session" are done at the same time, without a
power loss to the CDR2 off in the middle of the session.
