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

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 using Simpson 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 paralleled by a 0.15uF capacitor, in series with all exposed metal cabinet parts and a known 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, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor. (This test should be
performed with the 0.35 volt RMS or more is excessive and indicates a potential shock hazard which must be corrected before returning the
unit to the owner.

2.Use high-quality audio and video interconnect cables to connect your source equipment to the rear of the 2.0 as shown in the diagram above and the table below. It is important to note that unlike conventional audio/video equipment, the 2.0 does not have inputs that are labeled for connection to a specific type of equipment (e.g., inputs labeled “CD,” “Tape” or “VCR”). Instead, the 2.0 allows you to connect the analog or digital audio and composite or S-Video outputs of your source equipment to any of the inputs. Then, using the setup procedures detailed on page 28 of this manual, you can custom configure the input sources. However, for a quick starting point, follow the input suggestions outlined in the chart shown below. They conform to the preset conditions for the 2.0.

Quick Start Instructions
Signature 2.0
NOTE: To use the sources when they are connected as shown in the chart on the previous page, press the button name shown. The button names may not correspond exactly to the type of source used for any input profile, but you may rename the input source for the on-screen display by following the instructions shown on page 27 of this manual.
3. Connect the video “Record Inputs” of your VCR to the
Composite or S-Video “Rec” Outputs.
4.Connect the audio “Record Inputs” of your VCR and/or audio tape recorder to the “Rec” Outputs on the rear of the 2.0. There is no problem in sending the feed to both recorders and two recordings may be made at one time from the same source.
5.Connect the Composite or S-Video “Main” Outputs to the matching Composite or S-Video input on your TV monitor or projector.
6.Connect the AM and FM antennae supplied with the 2.0 to the proper antenna connections on the rear panel.
7.If a Signature Series audio power amplifier, or other compatible amplifier, is being used, connect the power trigger cable supplied with the 2.0 to the Trigger Output on the 2.0 and the amplifier’s compatible Trigger Input.
8.Connect the Audio Outputs of the 2.0 to the inputs of your five-channel power amplifier. Be certain that channels are properly matched (e.g., connect left to left, right to right, etc.) Connect the Sub Output to the mono “line level” input of a powered subwoofer, or to the audio input of the amplifier channel feeding a passive subwoofer. Connect the audio amplifier to the speakers, carefully following the instructions provided with the speaker and amplifier, and ensure that polarity is matched between the speaker and amplifier when connections are made.
9.Install the batteries in the remote control, being careful to observe the (+) and (–) polarity indicators on the remote and the batteries.
10.Connect all devices, including the 2.0, to AC
power and turn everything on EXCEPT for the 2.0 and any audio amplifier not connected to the 2.0’s triggered output.
11. Press the Master Power Switch on the 2.0 in until it latches and is flush with the front panel. A green standby LED will light, and the front panel Information Display will come on briefly to display the software version installed in your unit and then a Power Off Standby message will show briefly. The unit will then go into the Standby mode.
•To use the On-Screen Menu System, make certain that your TV or other video display device is turned on and switch to the proper video input at this point.
12. To turn the 2.0 on, press either the front panel Standby button, the Main On button on the remote, or any of the source buttons on the remote (e.g., TV, Vid 1, Tuner, etc.). The front panel Information Display will illuminate, the amber standby LED will go out and be replaced by blue illumination behind the word “Signature” on the front panel. A message will briefly appear in the on-screen display with the source, surround mode and volume.
•If you are using a Signature Series amplifier or another compatible amplifier connected to the Trigger Output jack, it will receive a turn-on signal as soon as the 2.0 is turned on. Note that with most amplifiers there will be a short, intentional delay between the turn-on signal and when the amplifier sends signals to the speakers. This is a normal function designed to prevent damage to your speakers.
•If you are using an amplifier not controlled by the 2.0’s Trigger Output, turn it on at least 10 seconds AFTER the 2.0 is turned on.

13.The factory presets for most settings are designed to accommodate the typical home-theater system. If the speakers being used are a “satellite/subwoofer” system with compact speakers at the front left/right, center and surround positions, and a subwoofer connected for lowfrequency reproduction, no further adjustment is needed. However, if you have larger front, center or surround speakers that are capable of low-frequency reproduction below 100Hz, or if a subwoofer is not installed, you should change the Speaker Setup, as shown on page 24 of this manual.
14.You may change the input source by pressing the front panel Source buttons or any of the Source buttons on the remote. Volume for the 2.0 may be raised or lowered using the front panel Volume knob or the Volume Up/Down buttons on the remote. Finally, to change the surround mode, press Surround buttons on the front panel or the Mono +, Music, Movies or Stereo buttons on the remote.
At this point you are “on the air”! Sit back and enjoy the best in home entertainment.
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.

IMPORTANT NOTE: Never make or remove any connections to the Signature 2.0 with the Master Power Switch in the “ON” position. It is also a good practice to make certain that the power amplifiers connected to the 2.0 are also turned off when making or removing any connections. This eliminates the risk of possible damage to your speakers or other system components.
When making connections to the Signature 2.0 make certain that the plugs are firmly seated into the jacks. This prevents intermittent connections which may interfere with performance.

Troubleshooting Guide
Signature 2.0
Troubleshooting Guide
The Signature 2.0 is designed for trouble-free operation. In normal use, most users will not encounter any trouble with the unit. However, as with any sophisticated electronic device, there may be occasional problems on initial installation or during the life of the unit. The items described on this page and in the table below are a brief guide to the minor problems that you may be able to correct yourself, and to certain anomalies that result from outside conditions.
If these solutions do not rectify a problem, or if the problem persists, contact your dealer or installer. Problems may also be solved by an authorized Harman Kardon Service Center. To locate the Service Center nearest you, call (800) 422-8027 toll free in the United States. Harman Kardon may be contacted via the Internet at www.harmankardon.com
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 y4until 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 xand 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 Switch 1and 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 Menu button jto view the Setup Menu. Press the Û Menu Control button iuntil Advanced Setup > is highlighted. Press the ÝMenu Control button ito go to the next screen.

|
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.
