connection or thermal overload, the Harman Kardon PA5800 will place itself in a “protect” mode to prevent damage to the amplifier. When this happens, the ring surrounding the power switch will flash and alternate between red and amber.

When this occurs, IMMEDIATELY turn off the unit using the power switch and cor- rect 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.
