Service Information / Troubleshooting Signature 2.1 If your installation has followed the procedures in this manual, you should enjoy many years of trouble-free operation and high-quality listening enjoyment. The 2.1 does not contain any user-serviceable parts. If you suspect a problem that may require service assistance, contact your dealer, installer or an authorized Harman Kardon service depot. You may also contact Harman Kardon via the World Wide Web at www.harmankardon.com It is important that any repairs be carried out only by an authorized Harman Kardon service agent to ensure proper service and preserve the protection of your Limited Warranty. It is a good idea to keep your sales slip or receipt in a safe place (along with this manual) so that it will be available to verify the purchase date for warranty claims. Input/Output Protection Under some conditions, such as a shorted speaker wire, DC voltage on an input connection or thermal overload, the amplifier will place itself in a "protect" mode to prevent damage to the amplifier. When this happens, the LED Power Indicator will flash and alternate between red and amber. When this occurs, IMMEDIATELY turn off the unit using the power switch and correct the problem. Then turn the unit back on. If the unit continues to go into a protect mode, contact your dealer or installer for assistance.
