Unpacking and Placement
Unpacking the CDD Unpack your CDD Compact Disc Drive and remove all accessories from the car-
ton.
Important! Keep all packing materials for future transport of your CDD.
Shipping your new component in anything other than its
purpose-designed packing material may result in damage
that is not covered by the warranty.
Remove the Transport Screws Place the CDD Compact Disc Drive upside-down on a soft, clean surface. Remove
the transport screws from the bottom of the unit and save them with the packing
materials for future use.
Warning! The transport screws must be removed before operating the
CDD, since they immobilize the transport mechanism during
shipping to prevent damage. These screws must also be
replaced before shipping the unit.
Placement of the CDD The CDD should be placed as close as possible to your digital audio processor,
thus keeping interconnect cabling reasonably short. It may be placed on a shelf
or in a cabinet where it is convenient to operate.
Drawings are included in this manual to facilitate special installations and custom
cabinetry (see Dimensions).

Operating Voltage
& Frequency
The CDD Compact Disc Drive is set at the factory (internally) for 100V, 120V,
200V, 220V, or 240V AC mains operation as appropriate for the country in which
it is to be sold. (230V/50Hz only in European Union countries, in compliance
with CE regulations.) Make sure that the label on the rear panel of the CDD (be-
side the AC input receptacle) indicates the correct AC operating voltage for your
location. Attempting to operate the CDD at an incorrect voltage can damage the
unit.
The CDD Compact Disc Drive is also set at the factory for operation on either 50
or 60 Hz AC line frequencies, as appropriate for the country in which it is to be
sold. It will not operate if it senses an incorrect line frequency.
Neither the voltage nor the line frequency setting may be changed by the user.

If the AC mains voltage or frequency indicated on your CDD is incorrect, please
contact your local, authorized Proceed dealer or distributor.
The CDD can easily be powered by a normal 15-ampere AC mains line. If other
devices are also powered from the same AC line, their additional power con-
sumption should be taken into account.

A Quick Start…
We recognize that many people are understandably eager to begin listening to
their new components, and that reading the manual is often done (if at all) at a
later time—perhaps while listening to music with the new product itself. We
strongly recommend that you read this manual thoroughly, as the CDD Compact
Disc Drive incorporates many unusual features that enhance its operation.
Fortunately, we can help you get some music up and running on your system
quickly, so that you may begin enjoying your new CD transport while reading
more about it. The goal here is simply to make some music as quickly as pos-
sible. The following procedure assumes that the rest of your system is already
connected (e.g., digital processor to preamplifier, to power amplifier, to speakers,
etc.).
1 TURN OFF YOUR ASSOCIATED COMPONENTS
This minimizes the opportunity for a momentary electrical surge disturbing
your system while making connections. If you have a large power amplifier,
allow its power supply to fully discharge before proceeding (which may
take as long as several minutes, depending on its design).
2 REMOVE THE TRANSPORT SCREWS FROM THE BOTTOM OF THE CDD
If you have not done so already, remove the slotted transport screws from
the bottom of the CDD now. Be sure to save them and all packing material
for possible future use. (Shipping the CDD without proper packing material
and without the transport screws in their proper positions may cause dam-
age to the unit that would not be covered by the warranty.)
3 CONNECT THE CDD TO AC POWER
Connect the AC cord to the CDD at the receptacle on the rear panel, and
then to your AC outlet. Depress the power button on the front panel. The
CDD will take a few moments to initialize and will then be ready to use.
4 CONNECT A DIGITAL OUTPUT TO A MATCHING DIGITAL INPUT ON YOUR
PROCESSOR
The CDD supports a variety of types of digital outputs to ensure compat-
ibility with any digital processor you might wish to use. These digital out-
puts are found on the rear of the CDD. Madrigal has found that, when fully
optimized at both ends, the AES/EBU professional digital interconnection
standard is the finest available. Depending on your processor, however, you
may find that a different interface is best in your system. It is important to
use high quality digital cable such as Madrigal MDC-1 for AES/EBU (via
XLRs), or MDC-2 for S/PDIF (via RCA or BNC) connections.
5 POWER UP THE REST OF THE SYSTEM, LEAVING THE POWER AMPLIFIERS
FOR LAST
Always turn the power amplifier(s) off first, and on last. This good habit
minimizes the opportunity for unexpected transients to be passed to your
loudspeakers.

9
6 SELECT THE INPUTS YOU ARE USING ON YOUR DIGITAL PROCESSOR
AND PREAMPLIFIER
Take care that a Tape Monitor switch does not override your selection of
the digital processor’s input on your preamplifier, or you will be struck by
how “quiet” your new digital source is.…
7 LOAD A DISC IN THE DRAWER AND PRESS PLAY; SLOWLY RAISE THE
VOLUME ON YOUR PREAMPLIFIER
Congratulations! You should now be able to enjoy your favorite music while
reading the rest of this manual. (Please, do read the rest of this manual.)
Warm up/break-in period Although your Proceed CDD Compact Disc Drive delivers outstanding perfor-
mance straight out of the box, you should expect to hear it continue to improve
as it reaches its normal operating temperatures and its various components
“break-in.” It has been our experience that the greatest changes occur within the
first few hours as the CDD reaches thermal equilibrium. Depending on how cold
the CDD was when you first connected it to AC power, full thermal equilibrium
might take as long as a day or two. After this initial break-in period, its perfor-
mance will remain quite constant, assuming that the unit is toggled between op-
erate and standby (rather than being turned fully off).
The only exception to this rule is if power is removed from the unit for a few
hours, allowing it to cool down. Depending on the degree of cooling involved,
you should expect a brief warm-up period before the CDD’s sound quality is at
its best. Unless your CDD was allowed to become quite chilled, subsequent ther-
mal re-stabilization should not take long.

Special Design Features
Congratulations on your purchase of the CDD Compact Disc Drive. The Madrigal
design team is confident you will enjoy the outstanding performance of the CDD
for many years. In case you are interested in technical details, what follows is a
brief outline of some of the key technologies in your new transport.
A New Generation The characteristics of an outstanding CD transport are simple to define: it must
recover the correct data from the disc, and deliver it to the digital processor with-
out any timing errors (sometimes called “jitter”). As simple as this sounds, achiev-
ing it in reality has been extremely difficult—as evidenced by the significant
sonic differences between various CD transports.
Conventional CD transport design depends on the quality of the oscillator used
to control the rate at which the disc itself spins. This oscillator exists in an ex-
tremely “noisy” electrical environment close to the motor that spins the disc. The
electrical noise introduces timing errors in the delivery of the digital signal that
have come to be known as “jitter.” Subsequent handling of the digital audio sig-
nal in traditional transport designs cannot improve upon this “jittery” signal, lack-
ing a better reference. To the contrary, the various stages of signal processing be-
tween the laser pickup and the final output can only contribute additional jitter of
their own.
The Proceed CDD leaps beyond conventional digital audio technology by em-
ploying a proprietary, closed-loop jitter-reduction system in conjunction with a
double speed CD-ROM drive. Using a custom-made crystal oscillator with better
than five part-per-million accuracy, the digital signal is reclocked immediately be-
fore the output, eliminating transport-related jitter from the digital audio signal.
This same crystal oscillator controls the all-digital servo used to control the rate
at which the disc spins.
In effect, the design of the CDD turns the accepted status quo on its head. By
placing the all-important reference clock in the final stage of the transport’s out-
put section, and slaving the mechanical subassemblies to it rather than the other
way around, the signal presented to the outputs of the CDD is uncontaminated
by electrically- or mechanically-induced jitter. The sonic advantages of this design
are immediately apparent in the clarity, warmth and stunning dynamic contrasts
exhibited by the CDD.
Digital Servo Control The laser mechanism used in the CDD uses all digital servo controls of its opera-
tions. Critical functions such as focus and tracking are handled completely in the
digital domain with mathematical precision. Whereas conventional, analog servos
require periodic realignments for optimum performance (to compensate for the
aging of various analog components), a digital servo remains stable over time,
never needing readjustment under normal conditions.
Output Versatility All high quality digital output configurations are supported in the CDD. A new
complementary driver for the balanced AES/EBU electrical output delivers out-
standing performance to the high quality XLR connector. Single-ended S/PDIF
electrical outputs are provided via both BNC and RCA connectors, and the
optional ST optical output uses a high-bandwidth Hewlett Packard®part for supe-

11
rior performance. (The ST output is a dealer-installable option to accommodate
those digital processors on which ST is the best-sounding input.)
All digital interfaces have been carefully optimized to deliver the finest perfor-
mance each interface standard allows. As a direct result, the CDD performs opti-
mally with any digital processor, without having to resort to techniques which
would limit its compatibility to other Proceed products.
Industrial Design The CDD shares the handsome industrial design of other Proceed components
such as the DAP digital audio processor. Dark buttons against a light face simplify
the operation of the CDD, even in a dimly-lit room.
The large, easily read display provides information as to the operational status of
the CDD from across the room, making the supplied remote control more genu-
inely useful than on products lacking such a display.
In keeping with its sophisticated design, the CDD also incorporates a Madrigal-
designed loading mechanism. Contrasting strongly with the bulky, plastic drawers
commonly used, the slim 1⁄8inch drawer is machined from a solid piece of alumi-
num and rides on highly polished steel and Teflon™ bearings. Its variable-speed
design opens and closes quickly, but without jarring the disc contained within,
nor risking a jam from dislodging it.
Convenience Features Too often, high performance CD transports have eschewed convenience in the
hopes of seeming more “performance-oriented.” While there were good argu-
ments for such a “minimalist” design in the days of analog turntables, the time is
long gone when the audiophile needed to give up operational convenience for
musical performance. After all, convenience features in a digital product are
largely a matter of writing appropriate software, and have no affect on the quality
of the digital data itself.
The CDD also supports custom programs, including “delete programming”
wherein selected tracks are omitted from the playlist. This allows the user to skip
the one or two songs on an otherwise good disc that have been overplayed ad
nauseam.

1 POWER & POWER LED
Assuming that the CDD’s power cord is connected to AC power, pressing
this latching power button connects the CDD to the AC mains and turns on
the unit. When power is restored after an interruption, the CDD will be
ready to operate (that is, it won’t be in standby mode), after a few mo-
ments’ delay to allow its circuits to stabilize.
While the CDD is in standby (see 9, below), the LED above the power but-
ton is red. When the CDD is ready to operate (that is, when it is not in
standby mode), this LED is amber. Naturally, when AC power is off, the LED
is off.
2 PROGRAM – AND PROGRAM + BUTTONS
Using these two buttons, the CDD can be easily programmed to play a spe-
cial “playlist,” or sequence of tracks, on any particular disc. Pressing pro-
gram + adds a selection to a program (or advances through an existing
playlist when reviewing a program you have already created).
Alternatively, it may simpler to omit the one or two songs that you have
heard too many times on the radio, playing the rest of the tracks in order.
Pressing program – will delete the selected track from the playlist, omitting
it on playback.
A program may be entered any time a disc is in the CDD and the unit is in
the stop mode. For detailed information on programming the CDD, see Pro-
gramming the CDD later in this manual.

13
3 PREV/REW BUTTON
Pressing this button momentarily will return you to the beginning of the
current track. Pressing it repeatedly will move you backward through the
available tracks, one at a time. Pressing and holding this button will instead
perform a reduced-volume reverse scan of the music, reminiscent of the
audible rewind function found on many cassette decks. This scanning mode
allows you to quickly find a particular point within a track.
4 PLAY/PAUSE BUTTON
Press this button in order to play a disc. If a programmed sequence of
tracks exists for that particular disc, the program will be played from its be-
ginning. Also, as you might expect, you may press the play button immedi-
ately after placing a disc in the CDD’s drawer; the drawer will close and the
CDD will enter the play mode as soon as it has read the disc’s table of con-
tents.
Pressing this button during play will pause the CDD at that point within
the track; the time display will blink slowly as a reminder that you are in
the pause mode.
the extended pause mode After about two minutes in pause, the CDD will go automatically into an
“extended pause” mode that stops the disc and turns off the laser against
the possibility that you have been called away and may not return for some
time. The extended pause mode is indicated by the display blinking more
slowly than in normal pause. You may force the CDD to enter extended
pause by pressing and holding the play/pause button for about five sec-
onds.
In effect, extended pause is much like stop, with the exception that press-
ing play will return you to the point on the disc where you had left off lis-
tening, after only a momentary hesitation to spin the disc back up to speed
and scan to the appropriate point.
5 NEXT/F.FWD BUTTON
Pressing this button momentarily will advance the CDD to the beginning of
the next track. Pressing and holding this button will instead perform a re-
duced-volume fast forward scan of the music, reminiscent of the audible
fast forward function found on many cassette decks. This scanning mode
allows you to quickly find a particular point within a track.
6 INFRARED TRANSCEIVER (WITHIN DISPLAY)
Infrared commands transmitted from the remote control are received by a
receiver behind this section of the display. Remote control of the CDD may
be unreliable if there is not a clear line of sight between the remote control
and the receiver (if the remote is far off-axis, or if the CDD is within a cabi-
net, for example). In such a case consider using a third-party IR repeater to
route the signal to the IR input jack on the rear panel (see Rear Panel,
CDD, below).
In addition to receiving IR commands, the CDD has the ability to teach a
learning remote control its own commands from an IR transmitter located
in this same area. (See Using Learning Remote Controls for more informa-
tion.)

14
7 TIME INDICATOR
The time section of the display can be set to display any of the following
four indications of time in minutes and seconds: time elapsed in track,
time elapsed on disc, time remaining on disc, time remaining on track.
These four options are accessed by pressing the display button to the right
of the display (see 9, below), which cycles through the four modes of time
display, using the time on disc and time remaining LEDs to indicate which
mode is chosen at any moment. When in stop, the indicated time will nor-
mally default to the total remaining time on the disc (or in the playlist for
the current disc, if programmed). This time indication may be changed if
desired once in stop.
8 TRACK INDICATOR
The next two characters are used to indicate the number of the track being
played. When a compact disc is loaded but the transport is in the stop
mode, this same space indicates the total number of tracks on the disc (or
in the program for the current disc, if programmed).
9 DISPLAY BUTTON
The display button cycles through the four time display modes used to in-
dicate where you are on the disc. These four display modes are:
•time elapsed in track (neither LED lit)
•time elapsed on disc (time on disc LED lit)
•time remaining on disc (time on disc and time remaining LEDs lit)
•time remaining on track (time remaining LED lit)
These four options are accessed by repeatedly pressing the display button,
which cycles through the four modes. In effect, the CDD assumes you will
be most interested seeing elapsed time on the current track; only depar-
tures from that assumption are denoted by LEDs. The CDD will remember
the last display mode selected and continue to display that information until
you change it, except in stop (when it always defaults to showing the time
remaining on disc, or in the disc’s playlist if it has been programmed). If
desired, once in stop the time indication may be changed to show any of
the other display modes.
“Hidden” Front Panel
Standby Button
Pressing and holding the display button places the CDD into standby
mode, which turns the display off, turns off all digital outputs, disables the
front-panel controls, and closes the drawer (if open). The internal circuitry
remains powered up in order to maintain its thermal stability and optimum
performance at all times.
Pressing standby, drawer, or play will bring the CDD out of standby, en-
abling the front panel controls, and reactivate the display and outputs.
10 DRAWER
The CDD employs an elegant, slim drawer that is machined from a solid
piece of aluminum. It is normally opened and closed by pressing the
stop/drawer button. If opened, it may also be closed simply by gently
pushing the front edge inward (as though you were going to close it manu-
ally). The CDD will interpret this as a request to close the drawer and take
over for you, smoothly closing the drawer.

15
If the CDD senses an obstruction during opening of the drawer mecha-
nism, it will attempt to re-close. If successful, it will read the disc’s table of
contents and display the disc’s number of tracks and total time (followed by
the playlist’s track and time information, if one exists). If for any reason the
drawer does not close fully, it will stop where it is and wait for your inter-
vention. After removing the obstruction, press the stop/drawer button again
to close the drawer normally.
Similarly, if the CDD senses an obstruction during the closing of its drawer
(as might be caused by an improperly seated CD, or an inquisitive child’s
finger), it will stop immediately and attempt to reopen. If the nature of the
obstruction prevents this also, it will stop where it is and wait for your inter-
vention. After removing the obstruction, press the stop/drawer button again
to close the drawer.
11 STOP/DRAWER BUTTON
Pressing this button once while a disc is playing will stop the disc, resulting
in the total number of tracks and the total time on the disc being displayed.
(Both the time on disc and the time remaining LEDs are lit to clarify the
meaning of the information being displayed at this point.)
Pressing this button once the disc has stopped, or if there is no disc in the
transport, will cause the drawer to open. If the disc is still playing, you may
press the button twice rapidly, to effect both the stop command and the
drawer open command; the CDD will remember the second button push
and execute it as soon as the disc has stopped spinning.
Pressing the stop/drawer button will cause an open drawer to close. If it
senses a disc in the drawer, the CDD will take a moment to read the disc’s
table of contents so that it may display the total number of tracks and the
total time on the disc for your information.
Finally, pressing and holding the stop/drawer button while the CDD is
stopped will display the version number of the operating software and its
checksum. This “hidden feature” allows you to double-check the version
number and integrity of the software in your unit without having to open it
up, should this ever become necessary.
12 REPEAT BUTTON AND INDICATORS
You may choose to either repeat the entire disc (including any programs
you might have entered for that particular disc) or an individual track by
pressing the repeat button. From normal operation, the first press of the
repeat button will light the disc LED below the display (number xx in the
front panel illustration). Pressing the repeat button again will light the track
LED (number xx in the front panel illustration). Pressing it a third time will
cycle out of any repeating mode, as will pressing stop/drawer at any time.
In either case, both repeat LEDs will be extinguished.
The disc repeat LED is lit when the CDD is set to repeat a disc (or a disc’s
program, if it has one) endlessly.
The track repeat LED is lit when the CDD is set to repeat a single track
endlessly.

16
13 TIME ON DISC AND TIME REMAINING LED INDICATORS
These LEDs are used to indicate which of the four available display modes
the CDD is in. The four indications of time that can be displayed are:
•time elapsed in track (neither LED lit)
•time elapsed on disc (time on disc LED lit)
•time remaining on disc (time on disc and time remaining LEDs lit)
•time remaining on track (time remaining LED lit)
These four options are accessed by repeatedly pressing the mode button,
which cycles through the four modes. If a custom playlist exists for the cur-
rent disc, time elapsed or remaining “on disc” refers to the playlist rather
than the entire disc.
14 RANDOM LED INDICATOR
By pressing rndm on the remote control, the CDD will enter a random play
mode in which the order of the current disc’s playlist is scrambled, and
then played. The random LED on the front panel will illuminate to indicate
this random play mode. Moreover, placing the CDD into random play
mode while the disc repeat function is engaged will cause it to play the
various tracks on the disc randomly indefinitely (until you stop it). This can
be a great way to provide background music during a dinner party, for ex-
ample.
15 PROGRAM LED INDICATOR
The program LED is used in conjunction with the program+ and program–
buttons to indicate those tracks that are either included in or excluded from
the current playlist. (See Programming the CDD for more information.)

1 AES/EBU DIGITAL OUTPUT
This output provides the digital audio signal (DAS) via cables equipped
with XLR-type connectors to the digital audio processor.
This input conforms to the Audio Engineering Society/European Broadcast
Union (AES/EBU) professional digital audio standard, which calls for a 110Ω
transmission of the DAS. Use a digital interconnecting cable specifically de-
signed for the 110ΩAES/EBU standard, such as Madrigal MDC-1 cable,
when using this input, with pin assignments as indicated below:
12
3
Pin 1: Chassis ground
Pin 2: non-inverted digital
Pin 3: inverted digital
Connector ground lug: chassis ground
It has been Madrigal’s experience that the AES/EBU interconnection stan-
dard offers the best quality of all digital transmission interfaces when fully
optimized, and we recommend its use wherever possible between Proceed
components.
However, optimizing any digital interface completely represents a significant
engineering challenge. It is entirely possible that a different type of input
may actually outperform a less-than-optimized AES/EBU implementation on
some brands of digital processors. For this reason, we have gone to great
lengths to fully optimize all four of the digital outputs on the CDD. If you
are using you CDD with a different brand of processor, we recommend ex-
perimenting to determine which type of input on that processor results in
the best audible performance.

This output provides the digital audio signal (DAS) via cables equipped
with BNC-type connectors to the digital processor.
This output conforms to the Sony/Philips Digital Interface Standard
(S/PDIF), which calls for a 75Ωtransmission of the DAS. Use a digital inter-
connecting cable specifically designed for the 75ΩS/PDIF standard, such as
Madrigal MDC-2 cable, when using this output. (In our experience, a BNC-
terminated S/PDIF cable has a slight advantage over the same cable termi-
nated with RCAs. This is probably due to the fact that a BNC connector has
a true 75Ωimpedance, whereas RCA connectors cannot.)
3 S/PDIF (RCA) ELECTRICAL DIGITAL OUTPUT
This output provides the digital audio signal (DAS) via cables equipped
with RCA-type connectors to the digital processor.
This output conforms to the Sony/Philips Digital Interface Standard
(S/PDIF), which calls for a 75Ωtransmission of the DAS. Use a digital inter-
connecting cable specifically designed for the 75ΩS/PDIF standard, such as
Madrigal MDC-2 cable, when using this output.
4 ST OPTICAL DIGITAL OUTPUT (OPTIONAL)
When so equipped, this output provides the digital audio signal (DAS), via
optical cable equipped with the ST-type optical connector (sometimes
called “AT&T”) to the digital processor. Your dealer can easily install the op-
tional ST input for you, should you require it. Please check with your dealer
regarding pricing and availability.
As delivered from the factory, the ST connection space in the rear panel of
the CDD is covered by a plastic plug. We have elected not to burden the
price of every CDD with the ST optical output for the simple reason that
the electrical interconnection standards (aes/ebu and s/pdif) provide supe-
rior performance when fully optimized.
If you are using a Madrigal-designed digital processor, we recommend us-
ing the aes/ebu connection for the best results; the two s/pdif electrical
connections follow closely behind aes/ebu. EIAJ is (unfortunately) the most
widely-used digital interconnection standard, yet offers the poorest perfor-
mance. We include it for compatibility reasons.
In some cases (with non-Madrigal products), the ST digital input of a par-
ticular digital processor may offer the best performance of the various in-
puts. In this case, your dealer can easily install the optional ST output for
you, should you require it. Please check with your dealer regarding pricing
and availability of the ST output kits.
5 EXTERNAL IR INPUT
The CDD incorporates an infrared repeater input to facilitate a wide range
of installation options. If desired, the CDD may be placed inside a cabinet
or outside the normal line-of-sight in the listening area, with the controlling
IR signal being relayed to the CDD by any of a number of commercially-
available IR repeaters.

The specifications for this IR input call for a triggering voltage of 5-12 volts
at no more than 100 milliamperes of current, with the tip of the 1⁄8" mini-
plug having positive polarity, as below:

If you would like more information on the possibility of using an infrared
repeater with your CDD, please contact your Proceed dealer.
6 AC POWER INPUT
This input accepts AC power from the AC mains (via the supplied AC
cable).
The CDD is set internally for 100, 120, 200, 220, or 240VAC mains operation
at either 50 or 60Hz. Make sure that the label on the rear of the unit (next
to the AC input receptacle) indicates the correct AC operating voltage and
frequency for your location.
Connect the female end of this cable to the CDD. Connect the male end of
this cable to wall outlet or to an “unswitched” convenience outlet like those
found on some audio components.

The power consumption of the CDD is only 20 watts. As such most people
will leave it on (or in standby) at all times. If you elect to place the CDD on
a switched outlet, we advise waiting at least five seconds between power
cycles to allow the normal power-up sequence to complete without inter-
ruption.

Remote Control, CDD
1 IR TRANSMITTER WINDOW
The CDD’s Remote Control sends infrared (IR) commands through its pro-
jection lens, and the CDD receives IR commands through its Remote sensor
window. (See “Front Panel, CDD”). If either of these lenses is obstructed,
no IR commands can be received by the CDD. If you notice IR perfor-
mance deteriorating, you may want to clean these lenses with a soft cloth
and some glass cleaner. (Spray the cleaner on the cloth first, and then wipe
the lens with the moistened cloth. Do not spray the cleaner directly on ei-
ther lens, as this may allow moisture to migrate into the electronics behind
the lens assemblies.)
2 TRANSPORT BUTTONS
The buttons used for routine operation of transport functions on the CDD
are grouped at the top of the remote control. They include:
(/dwr) stop/dwr: Press to stop play. The same button will operate
the drawer if stopping the disc has no relevance (e.g., if it is al-
ready stopped, or if there is no disc inside the CDD).
(/) previous/rewind: When pressed and released quickly, this
will take you to the beginning of the current track; when pressed
repeatedly, this button will step you backwards through the previ-
ous tracks, one at a time. ( is the international symbol for previ-
ous). When pressed and held, the CDD will enter a reverse au-
dible scanning mode similar to the familiar rewind function of
many cassette decks, allowing a precise location within a track to
be located.
( / ) play/pause: Press to enter the play mode from either stop,
pause or standby, or to restart play at the beginnning of the
track currently playing. When in play mode, press to pause play
in the current location. If left in pause mode for more than two
minutes, the CDD will enter extended pause mode, shutting
down both the laser and the drive motors to enhance longevity
and reliability. Upon pressing pause or play a second time, the
disc will spin up and begin playing from the location where it
had been paused.
(/) next/fast forward: When pressed and released quickly, this
will take you to the beginning of the next track. ( is the interna-
tional symbol for next). When pressed and held, the CDD will
enter a fast forward audible scanning mode similar to the familiar
fast forward function of many cassette decks, allowing a precise
location within a track to be located.
