Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits 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 ES devices, place the assembly on a conductive surface such as aluminum foil, to

prevent electrostatic charge build-up or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES 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 ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement

ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the

chassis or circuit assembly into which the device will be installed.

CAUTION :

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together

or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

Each precaution in this manual should be followed during servicing.

Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with

, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the

parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably

insulated from the supply circuit before retuming the product to the customer.

Signature 2.0 Processor/Tuner harman/kardon

Before returning the unit to the user, perform the following safety checks :

1. Inspect all lead dress to make certain that

leads are not pinched or that hardware is not

lodged between the chassis and other metal

parts in the unit.

2. Be sure that any protective devices such as

nonmetallic control knobs, insulating fish-

papers, cabinet backs, adjustment and

compartment covers or shields, isolation

resistor-capacity networks, mechanical

insulators, etc. Which were removed for the

servicing are properly re-installed.

3. Be sure that no shock hazard exists ; check for leakage

current usingSimpson Model 229 Leakage Tester, standard

equipment item No. 21641, RCA Model WT540A or use

alternate method as follows : Plug the power cord directly

Into a 120 volt AC receptacle (do not use an Isolation

Transformer for this test). Using two clip leads, connect a

1500 ohms,10watt Resistor paralleledby a 0.15uFcapacitor,in series withall exposed metal cabinetparts and aknown earth ground,such

as a water pipe or conduit. Use a VTVM or VOM with 1000 ohms per volt, or higher sensitivity to measure the AC voltage drop across the

resistor. (See diagram) Move the resistor connection to each exposed metal part having a return path to the chassis (antenna, metal,

cabinet, screwheads, knobsand controlshafts, escutcheon, etc.) and measure the ACvoltage dropacross theresistor.(This test should be

performed withthe 0.35 volt RMS or more is excessive and indicates a potential shock hazardwhich must becorrected before returningthe

unit to the owner.

Signature 2.0

Important Safety Information

Verify Line Voltage Before Use

This Signature 2.0 has been designed for use with
120-volt AC current. Connection to a line voltage other
than that for which it is intended can create a safety and
fire hazard, and may damage the unit.

If you have any questions about the voltage require­ments for your specific model, or about the line voltage
in your area, contact your selling dealer before plugging
the unit into a wall outlet.

Do Not Use Extension Cords

To avoid safety hazards, use only the power cord
attached to your unit. We do not recommend that
extension cords be used with this product. As with all
electrical devices, do not run power cords under rugs
or carpets or place heavy objects on them. Damaged
power cords should be replaced immediately with cords
meeting factory specifications.

Handle the AC Power Cord Gently

When disconnecting the power cord from an AC outlet,
always pull the plug, never pull the cord. If you do not
intend to use the unit for any considerable length of
time, disconnect the plug from the AC outlet.

Do Not Open The Cabinet

There are no user-serviceable components inside this
product. Opening the cabinet may present a shock
hazard, and any modification to the product will void
your guarantee. If water or any metal object such as
a paper clip, wire or a staple accidentally falls inside
the unit, disconnect it from the AC power source
immediately, and consult an authorized service station.

CATV or Antenna Grounding

If an outside antenna or cable system is connected to
this product, be certain that it is grounded so as to
provide some protection against voltage surges and static
charges. Section 810 of the National Electrical Code,
ANSI/NFPA No. 70-1984, provides information with
respect to proper grounding of the mast and supporting
structure, grounding of the lead-in wire to an antenna
discharge unit, size of grounding conductors, location
of antenna discharge unit, connection to grounding
electrodes and requirements of the grounding electrode.

NOTE TO CATV SYSTEM INSTALLER:

This reminder is provided to call the CATV (Cable TV)
system installer’s attention to article 820-40 of the NEC
that provides guidelines for proper grounding and, in
particular, specifies that the cable ground shall be
connected to the grounding system of the building, as
close to the point of cable entry as possible.

Installation Location

■ To assure proper operation, and to avoid the potential
for safety hazards, place the unit on a firm and level
surface. When placing the unit on a shelf, be certain
that the shelf and any mounting hardware can support
the weight of the product.

■ Make certain that proper space is provided both above
and below the unit for ventilation. If this product will
be installed in a cabinet or other enclosed area, make
certain that there is sufficient air movement within
the cabinet. Under some circumstances a fan may
be required.

■ Do not place the unit directly on a carpeted surface.

■ Avoid installation in extremely hot or cold locations,

or an area that is exposed to direct sunlight or
heating equipment.

■ Avoid moist or humid locations.

■ Do not obstruct the ventilation slots on the top of the

Operating Hints

The following hints will help you to enjoy the sonic
power and operating flexibility of the Signature Series

2.0 while you become accustomed to the way it works.
Depending on the type of equipment in use in your
system, it may, or may not be necessary to follow
these hints:

•

If you change the Speaker Setup, keep in mind that the
changes apply to all modes. You may not change the
Speaker Setup for one mode, and not another.

•

When the front channel speakers are set to the LARGE
mode, the subwoofer output will only be active when a
Dolby* Digital source with Low-Frequency Effects (LFE)
or DTS are in use. In order to have a full-time output
from the subwoofer channel, the front speakers must be
set to SMALL. (This is the factory preset configuration.)

•

If the Surround Mode indication flashes in the front
panel display, that is an indication that the input source
is not compatible with the desired mode. The flashing
mode is not the one originally selected, rather, it is the

mode automatically selected by the 2.0 to match the
input source. For example, when the Pro Logic* mode
is selected, but a Dolby Digital source is playing, the

2.0 will automatically select Dolby Digital, but the
mode will flash to remind you that while it is correct,
it is not the mode originally selected.

•

Note that when a DVD is in use, the digital audio out­put is interrupted when the player is in the pause, fast
search, slow speed or reverse modes. Since the 2.0 does
not receive a digital signal in these cases, it will
momentarily try the Pro Logic mode as an alternate.
This temporary mode change does not indicate any
fault or problem with the 2.0, and the unit will return
to the Dolby Digital or DTS Mode shortly after the
DVD is put back into a standard play mode.

•

If one input source requires a significantly higher
volume level than others, or when there is a distinct
increase in the noise level or distortion with one input
in comparison to others, this is a sign that the input
level needs to be adjusted. See pages 29–30 of this
manual for instructions on adjusting the input level.

•

When certain DVD players are used, it is normal to hear
an occasional click or pop noise when the DVD player
is put back into play after being paused, or when some
DVD discs change chapters. This is a normal side effect
of the way in which some DVD players and digital
decoders work, and it does NOT indicate a problem
with the 2.0 or with your DVD player.

Of course, this is only the tip of the iceberg. Although
you have successfully completed a minimal installation
we strongly recommend that you take time to read this
manual thoroughly. It will show you how to use the
many features, modes and controls that are a vital part of
the Signature 2.0. Correct setup and installation is impor­tant to optimizing the sound quality of your new con­troller, and will also make it easier to operate. A few
minutes spent reading the manual and making certain
that your new 2.0 is set up to meet the individual
characteristics of your system and listening room will
enable the 2.0 to deliver all the performance it is
capable of.

Error Messages

When the surround mode name blinks in the front panel

Information Display

(Figure FPD-12) that is your
indication that there is a mismatch between the input
source and the surround mode, or that there is no digital
input at all.

Mode Mismatch

Certain modes are digital only, while others operate with
analog signals only. The blinking light is an indication of
a source/mode mismatch.

When this condition exists, the 2.0 will automatically
select a properly matched surround mode and continue
normal operation. To view the name of the mode
selected, press the

Display

button x. The correct

mode will be displayed next to the

Alt Mode

indication (Figure OSD-27). To stop the flashing
message, press the appropriate

Surround Mode

Selector y 4

until the correct mode is selected.

No Data

If the mode name flashes when the mode and input are
matched, this is an indication that the 2.0 is not receiving
digital data from the source machine. This will typically
occur when a DVD player is in pause or a fast scan

mode, as no digital data is typically output unless the
disc is playing. To confirm that the lack of data is the
cause of the error message, press the

Display

button

x

and check the on-screen status screen. If a

NO

AC-3 Info

message appears (Figures OSD-14/
OSD-18/OSD-27), this is your indication that the player
is not sending a digital signal. Put the unit into Play,
check the digital input connections or check to see that
a digital input is selected to solve this problem.

Digital Noise With DVD Players

Certain early models of DVD players may occasionally
cause a sharp “crack” or “snap” in the output channels
during track or chapter changes. This is caused by a
momentary discontinuity in the digital data output
which is not long enough to trigger the flashing error
message, but long enough to disrupt the processor. This
type of random noise is caused by the DVD player, and
it does not indicate a problem with the 2.0.

System Reset

In rare cases where the 2.0’s operation or the displays
seem abnormal, the cause may be erratic operation of the
system’s memory or microprocessor.

The first step to correct this problem is to turn the 2.0
off using the

Master Power Switch1

and unplug
the unit from the AC wall outlet and wait at least
three minutes. After the pause, reconnect the AC power
cord and turn the unit on again. If the system still
malfunctions, a system reset may clear the problem.

Note that clearing the system memory may correct the
problem, but will also erase all system configuration
data, input source assignments, input profile names,
effects level settings and tuner preset memories. It is
always a good idea to record your system configuration
information in the Worksheets in Appendix B, if possible,
before resetting the system. To reset the system, press
the

Service bulletin # H/K2000-07 July 2000 Warranty labor rate: MINOR repair

To: All harman/kardon Service Centers

Models: Signature 2.0 Processor/Tuner

Subject: Remote Control Works Intermittently

In the event you receive a Signature 2.0 with the complaint of “the remote control only works at
certain angles, or when it’s very close to the unit,” perform the necessary steps listed below:

1. Make sure there are fresh batteries in the remote, and they are installed correctly.

2. Question for customer: Are you sure the area between the remote control and receiver is not
blocked by some object, and the distance is no more than 15 feet, at an angle no greater than 30°
from the front of the receiver ?

3. Question for customer: Are you sure strong lighting is not being directed towards the IR sensor of
the unit ?

If the remote control of the Signature 2.0 Processor/Tuner still does not function correctly under
proper conditions, then verify that the position of the IR sensor located behind the Signature 2.0
front panel is correct, as per steps below.

4. Remove the top cover to the unit (10 Phillips screws).

5. In the front left corner, carefully unplug the two colored female connectors on the Power Switch PCB.

6. Remove the (5) Phillips screws holding the front panel onto the chassis; there is one screw on either
side, and three bottom screws.

7. Carefully disengage the front panel from the chassis; you may now remove the four plated Phillips
screws deep in the recesses of the stamped metal cover plate at the rear of the front panel. A
magnetic screwdriver bit is recommended.

8. Disengage rear cover from the front panel; you should now see the rectangular IR sensor at the left
side of the VLF display. Align and straighten the sensor as indicated below; it should be straight and
parallel in relation to the front panel; the rounded lens should be pointed straight forward.

9. Replace all screws and reassemble, following the instructions in reverse order; be sure and replace
the two power switch connectors.

10. Connect all cables necessary for proper operation; power up the unit and check that the remote
control is working properly.
