AVR

Front-Panel Controls, continued

Power Indicator:

This LED has three possible modes:

• LED is off: Indicates that the AVR is unplugged or the rear-panel Main Power switch
is

off.

• LED glows amber: Indicates that the AVR is in the Standby mode.

• LED glows white: Indicates that the AVR is turned on.

IMPORTANT NOTE:

If the PROTECT message ever appears on the AVR’s front-

panel message display, turn off the AVR and unplug it from the AC outlet.

Check all speaker wires for a possible short-circuit (the “+” and “–” conductors
touching each other or both touching the same piece of metal). If a short-circuit
is not found, bring the unit to an authorized Harman Kardon service center for
inspection and repair before using it again.

Message display:

Various messages appear in this two-line display in response

to commands and changes in the incoming signal. In normal operation, the current
source name appears on the upper line, while the surround mode is displayed on
the lower line. When the on-screen display menu system (OSD) is in use, the current
menu settings appear.

IR sensor:

This sensor receives infrared (IR) commands from the remote control.

It is important to ensure that the sensor is not blocked.
