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 y4 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

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 1 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 Menu button j to view the Setup Menu. Press the Û Menu Control button i until Advanced Setup > is highlighted. Press the ÝMenu Control button ito go to the next screen.
