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 cot-
ton 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 compo-
nents 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 com-
monly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated cir-
cuits 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 sur-
face 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 gen-
erate static electricity sufficient to damage an ESD device).
CDR 26 SPECIAL NOTICE
Under certain circumstances, the CDR 26 may operate differently than the description in
the owner’s manual.
In particular, the unit will not be able to make a digital recording from an external
source such as a CD player, DVD player or MiniDisc (MD) player (as shown on
page 20 of the owner’s manual) when that player blocks a special electrical signal,
called “Sub-Q,” from the digital output. This signal contains some of the data
needed to tell the CDR 26 that the original disc has started playing, and without it
the CDR 26 cannot begin a recording.
This is outside of our control, as some manufacturers design products this way to
prevent digital copies from being made. Should you find that a digital recording cannot
be made from an external playback source, you may always use an analog connection
to make the copy by pressing the Input Select Button on the front panel or remote
control until ANALOG appears in the Information Display.
This does not affect the CDR 26’s ability to make high-speed dubs using the unit’s own
internal playback deck, and in many cases you will not encounter this problem at all,
since it is related to the brand of playback deck being used.

12 INSTALLATION AND CONNECTIONS
INSTALLATION AND CONNECTIONS
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 26, be turned off and unplugged
from their AC power source when any connections are
made or a new component is installed.
Placement of the CDR 26
Since the CD transports in the CDR 26 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 26 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 26 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 26 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 26, 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 26, think of the process as
if you were connecting a standard tape or cassette
recorder,with the addition of the digital connections.
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 26’s functions resemble
those of a standard tape recorder,this may make it
easier to select it as an input on your receiver or pre-
amp.Connect the
Analog Output Jacks ¡ to the
Play/In jacks of a Tape or Aux input on your receiver
or preamp.Connect the
Analog Input Jacks ™ to
the Tape Rec/Out jacks on your receiver or preamp.
To play the output through the digital decoder in
your receiver or an external processor, connect the
Coaxial-Digital Output Jack £ or the Optical-
Digital Output Jack
§ to the matching digital-input
jack on your receiver or processor.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
Coaxial-
Digital Input Jacks
&¢ or Optical-Digital Input
Jacks
^∞ on the CDR 26 to the digital output
jacks on your receiver or processor.If your receiver
does not have digital-output jacks,you may connect
the
Coaxial-Digital Input Jacks &¢ or Optical-
Digital Input Jacks
^∞ on the CDR 26 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 or Optical
Digital Output of the player to one of the front-panel
Digital Inputs ^& on the CDR 26.
IMPORTANT NOTE 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 26 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 26, consult your dealer.
14
INSTALLATION AND CONNECTIONS 13
INSTALLATION AND CONNECTIONS
Batteries
Insert the two AA batteries supplied with the CDR 26’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 is 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 26 is installed behind a cabinet or other
obstruction that may block the path between the front-
panel
Remote Sensor ˆ 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 26 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 ª to an AC power
source.The CDR 26 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 prod-
uct is used, make certain that the total power of all
products connected does not exceed the maximum
rated output of the product containing the outlets.
If the CDR 26 is connected to a switched outlet,
remember to turn on the outlet or product controlling
it in order for the CDR 26 to operate.
