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).

HD 990 Rear Panel Connections
Digital Output: Connect this jack to the coaxial or optical digital input of an external
digital-to-analog converter for direct access to the digital signals of the CD player or the
external digital audio source. DO NOT connect this jack to the standard audio inputs of
any device.
1Audio Outputs: Connect these jacks to the CD audio inputs of your receiver, surround
processor or preamplifier. If your amplifier features balanced XLR inputs, you may use
the XLR outputs instead. Sound quality via balanced connection is usually more dynamic,
with even better signal-to-noise ratio. Pin configuration for the XLR Outputs: Pin 1 is
Ground, Pin 2 is Plus/Hot, Pin 3 is Minus/Cold.
2Remote Control Input: Connect the output of a remote infrared sensor or the remote
control output of another compatible Harman Kardon product. This will enable the remote
control system to operate even when the front panel remote sensor is blocked. It will also
allow use of the CD player with optional, external control systems.
3Remote Control Output: Connect this jack to the input of another compatible
Harman Kardon remote-controlled device to have the remote sensor on the CD player
provide signals to other products.
4AC Power Cord: Connect this plug to an AC outlet. If the outlet is switch-controlled,
make certain that the switch is in the On position.
5Coaxial and Optical Digital Inputs: Connect these jacks to the coaxial or optical
digital output of an external audio source. This will enable you to have the digital-to-
analog conversion of that source done by the highgrade audiophile digital-to-analog
convertors in the HD 990 rather than the (older ones) in the external source, for better
audio quality.
6HRS-Link Output: The special High-Resolution Synchronization Link cable (optional)
connects to the HRS jack on the matching HK 990 amplifier (or other compatible HK
amplifiers) to attain an even higher quality of sound. You need only connect the HRS-Link

Input/Source Selection
A unique feature of the HD 990 is that it allows other source components to be played
back using the high-grade audiophile digital-to-analog convertors inside the CD player.
Especially source components using older and less powerful convertors will benefit from
this feature.

HD 990 Programmed Play Operation
Programmed Play
The HD 990’s advanced programming capability enables you to select certain tracks, to
preset the order in which these tracks play, and to clear specific programmed tracks after
the program was made.
Programmed play allows you to program up to 32 tracks into the HD 990’s memory. To
begin programming the CD player, make sure that the unit is in Stop mode, then press

Program button d. The Program indicator will light in the Information Display
1, the number 001 will blink below the Program indicator, showing the track number
selected, and PROG-01: 001 will appear in the Information Display, replacing the
track time. This indicates that you are about to program the first track.
You may now begin to enter the tracks in the order in which you wish to have them
play. To select a track on the disc, press the
Numeric buttons ccorresponding to the
desired track. Be certain to enter the second and/or third number of two- or three-digit
numbers within two seconds after the first number was entered. You may also use the
Skip buttons 78hto select a track. When the track is selected, press the Program
button d. Note that the program-step indication on the right side of the Information
Display will change to PROG-02: 001.
You may now select another track for the next program step, following the instructions
shown above. When the track is selected, press the
Program button dagain. Repeat
this procedure for each program step until you have completed the desired programming.

number will be displayed in the programmed order, but with steady track numbers (not
blinking) in contrast to the programming mode. As soon as the track number starts
blinking (this will take 1 second), the appropriate program step number shown at the left
side is not programmed yet; now you can change the track number with the Skip buttons
78hor the Numeric buttons cas described above and add it to the program
list by pressing the Program button d.
Pressing the
Stop button 6ktwice will return to normal mode and the Program
indicator will go out, but the program will stay in memory and can be recalled easily by
