INSTALLATION AND CONNECTIONS  13

Batteries
Insert the two AA batteries supplied with the
CDR 20’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 mat-
ing 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 extend-
ed 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 20 is installed behind a cabinet or
other obstruction that may block the path
between the front-panel Remote Sensor Û 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
ª on the rear-panel. This jack may also be con-
nected to the IR Output jack of another compati-
ble Harman Kardon component or a compatible
IR system remote product.

You may also use the IR Sensor in the CDR 20 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 20 uses sensitive, high-
performance 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 maxi-
mum rated output of the product containing the
outlets. If the CDR 20 is connected to a switched
outlet, remember to turn on the outlet or prod-
uct controlling it in order for the CDR 20 to
operate.

14 CD RECORDING BASICS

CD Recorders (CDRs) are similar to standard CD
players, with the addition of the features and
controls needed for recording. Functions such as
play, search and programming for playback will
be familiar, but the recorder will function slightly
differently than what you may be used to for
magnetic tape recorders.

Disc Types
Unlike a conventional CD player, the CDR 20
uses three types of discs, and it is important to
understand how each one plays.

Both decks in the CDR 20 will play

back any conventional CD that bears this logo.

Discs that bear this logo or whose

packaging is labeled with ”Digital Audio“ and
“CD-R“ or “CD Recordable“ may be recorded
on one time, and when they are finalized they
will play in either deck in the CDR 20 or in any
conventional CD player, including home, car and
portable models. The Record Deck % on the
CDR 20 may also be used to record on these
discs, and it will play CD-R/Audio discs even if
they have not been finalized.

Discs that bear this logo or whose

packaging is labeled with ”Digital Audio“ and
“CD-RW“ or “CD Rewritabel“ may be recorded,
and they may also be erased and reused. They
may be recorded on or played on the Record
Deck % of the CDR 20 and in other CD-RW
recorders or CD-RW compatible players.
CD-RW Audio discs will play on most DVD play-
ers once they have been finalized.

Discs designed for use in

computer CD-R drives may not be used for
recording in the CDR 20. Only discs specifically
designed for use in consumer CD audio
recorders may be used. If you attempt to use a
blank-computer-type recordable disc for recording
on the CDR 20 you will see a NO AUDIO
message in the Information Display K if
Record 8 or Dubbing ) button is pressed
and  recording will not be possible. However,
discs that have been recorded in the CD-R drive
of a computer may be played in the CDR 20,
provided that they have been properly finalized
in accordance with audio standard IEC958.

Note that the CDR 20 is specifically designed for
the recording and playback of consumer audio
discs, and cannot be used to copy data discs,
DVD discs, or other optical discs used by video-
or computer-game systems.

CDR Terminology and Display Messages
Compact disc recording has its own special ter-
minology, and some of the messages you will
see when using the CDR 20 may be new to you.
Before using the CDR 20, you may wish to famil-
iarize yourself with some of the terms used by
the CDR 20. Additional error message displays
may occasionally appear. Please see page 23 for
a complete explanation of those messages.

Finalize

: This term refers to the process

that completes the recording of a disc by record-
ing a final Table of Contents and preparing the
disc so that it may be played on other machines.
A CD-R disc may not be played on other CD
players until it is finalized. However, once the
finalization process is complete, a CD-R disc may
not be recorded on again. CD-RW discs only may
be “Unfinalized,” so that additional tracks may
be recorded on a disc.

TOC

: Stands for Table of Contents and it refers

to the data recorded on each CD that tells the
player how many tracks are on the disc, the total
time of the disc and the running time of each
individual track. Each time a disc of any sort is
placed in the CDR 20, you will see a TOC to
indicate that the unit is reading this data from
the disc. This is required to copy the track infor-
mation to any recording.

OPC

: Stands for Optical Processing Calibration.

When you see this message in the Information
Display for the Record Deck K, it means
that the laser transport inside the unit is making
the calibrations and adjustments needed so that
the recording process is optimized for the specif-
ic disc in use.

BUSY

: When you see this message, it means

that the Record Deck is completing part of the
record operation. When you see this message, do
not press any buttons; simply wait until the mes-
sage clears from the display.

DISC FULL

: When there are only four sec-

onds of record time remaining on a blank disc, a
DISC FULL

message will appear in the

Information Display K. When you see this
message, you will need to stop the recording
process and, when a CD-R is being recorded,
insert a new blank disc or, when a CD-RW is in
use, either use a new disc or erase existing
tracks following the instructions on page 22.

PLAYBACK BASICS  15

Playback of CDs on the CDR 20 resembles that
for traditional CD players with a few exceptions
to accommodate the availability of two separate
playback decks. Before using the CDR 20,
power-up the unit by pressing in the Main
Power Switch 1 until it latches. Note that the
Status-Mode Indicator 2 will turn green,
indicating that the unit is on and functioning. At
the same time, the Information Display Ú
will illuminate and the legends behind the front-
panel controls will also light up.

Once the Main Power Switch 1 has been
turned on, the CDR 20 may be powered-on or -
off using the remote control. Pressing the
Power-Off button 

 on the remote will place

the unit in a Standby mode, as indicated by the
amber color of the Status-Mode Indicator
2

. To turn the unit on using the remote, simply

press the Power-On button 

0.

Note that when the unit is in the Standby mode,
it is still drawing power from the AC main out-
lets. To turn the unit completely off, press in the
Main Power Switch 1 slightly, and then
release it so that it pops forward. When the
Status-Mode Indicator 2 goes out, the CDR
20 is off and not drawing any power. When you
will not be using the unit for an extended period
of time, such as during a vacation, we recom-
mend using the Main Power Switch 1 to
turn the unit completely off.

Although compact discs are very reliable, rough
handling may damage them. Avoid scratching
the bottom (nonprinted) side of the discs, as this
will affect playback of standard CDs and inter-
fere with the recording of CD-R and CD-RW
discs. It is also a good idea to always handle
discs by their edges to avoid fingerprints which
may also interfere with playback quality and
possibly cause damage to the laser and lens
assembly.

Loading and Unloading Discs
To load a disc, first open the desired CD deck by
pressing the appropriate Open/Close button
7 $

2 . The word OPEN will appear in

the Information Display K. Always make cer-
tain that there is sufficient room in front of the
unit for the disc drawers to open. Note that if
either disc drawer is blocked, the drawer will
stop at the blocked position and an ERROR
message will appear. Press the appropriate
Open/Close button 7 $

2  to reopen

the drawer.

Load a disc in the tray with the printed (label)
side facing up. Once the disc is seated, make
certain that it is properly centered within the
tray. When using 8 cm (3") single discs, take
extra care to make certain that the disc is care-
fully centered within the smaller ridges in the
disc tray.

To close the drawer, press the appropriate
Open/Close button 7 $

2  or gently

press on the outside of the front cover of the
disc tray. When the drawer is closed the word
CLOSE

will appear momentarily in the

Information Display K, and the letters TOC
will begin to flash in the display once the drawer
s completely closed.

If the disc is a standard CD or a finalized CD-R
or CD-RW disc, TOC will flash while the unit
reads the disc’s Table of Contents information.
Once that data is read, the Information
Display K will show the total number of tracks
and the total time of all tracks on the disc. The
CD Indicator S will also light to indicate that
a standard CD is in use.

When an unfinalized CD-R or CD-RW disc is
placed in the Record Deck %, the letters
OPC

will flash once the Table of Contents has

been read. This indicates that the unit is optimiz-
ing its circuits for maximum compatibility with
the specific recordable disc in use. the number
and total running time of any tracks that have
already been recorded will appear in the
Information Display K, and the appropriate
indicator SP will light to tell you if a CD-R or
CD-RW disc is in use.

If a computer data disc is placed in the CDR 20,
a DATA DISC or DISC ERROR mes-
sage will appear, depending on if the data disc is
finalized or not. Data discs will not play, and
may not be recorded or dubbed on the CDR 20.

Using The Remote
The CDR 20’s infrared remote control is designed
to operate both CD decks, as well as control the
playback programming and record functions. To
allow for efficient use of the remote, it’s opera-
tion is different from standard CD players. Some
buttons are dedicated to one specific CD deck,
while others are shared between the two decks.

No matter which deck is playing, the Play Deck
(CDP) and Record Deck (CDR) Display
1! and Open/Close buttons 2  will
always send a command to their respective
deck. The other transport and programming
functions, however, are shared. To use any of the
transport controls, such as Play

9, Stop N,

O or the Search and Skip buttons

58P, the Numeric Keys F or the
Programming Keys

467AH, first

press either the CDP button

3 to command

the Play Deck 3 or the CDR button 

 to

command the Record Deck %. When the but-
ton is pressed, a message reading CDP or CDR
will appear in the appropriate Information
Display K to confirm the selection.

To switch the remote from controlling one deck
to controlling the other, simply press the Select
button 

3 for the deck you wish to control

at any time.

Note that features relating to the recording
process, such as Speed

I and the double row

of record-function buttons in the center of the
remote 

BCDEJKLM and

the Single/Dual buttons 

6Q are dedicated

feature buttons that do not require any special
selection.

finishes, the disc in the other drawer will begin
to play. When the Dual button 

Qı is

pressed so that the Dual-Play Indicator J is
lit, each deck will operate as a separate, single-
play CD unit without regard to the status of the
other deck. For complete information on Dual-
Deck and Dual-Play operation, see page 17.

At the end of a listening session, remove the
discs from the decks by following the instruc-
tions shown on the previous page. Do not leave
