If your installation has followed the procedures
in this manual, you should enjoy many years of

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's 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 war-
ranty claims.
Input/Output Protection Mode
Under some conditions, such as a shorted
speaker wire, DC voltage on an input connec-
tion or thermal overload, the Harman Kardon
PA 2000 will place itself in a Protect mode to
prevent damage to the amplifier. When this
happens, the Protect Indicator 4 will light.
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.
