Memory Backup
This product is equipped with a memory
backup system that preserves tuner pre-
sets and system configuration informa-
tion if the unit is accidentally unplugged
or subject to a power outage. This mem-
ory will last for approximately one week,
after which time all information must be
re-entered.

System Reset
In the rare case where the unit’s opera-
tion or the displays seem abnormal, the
cause may involve the erratic operation of
the system’s memory or microprocessor.

To correct this problem, first unplug the
unit from the AC wall outlet and wait at
least three minutes. After the pause,
reconnect the AC power cord and check
the unit’s operation. If the system still
malfunctions, a system reset may clear
the problem.

To clear the entire system memory of the
unit, press and hold the 

Ú

and

Û

buttons until 

CLEAR MEMO

appears in the front panel display.
Release the buttons and note that the
unit will turn off. Remember that once
you have cleared the memory in this

fashion it will be necessary to re-establish
all system configuration information
and tuner presets.

If the system is still operating incorrectly,
there may have been an electrostatic dis-
charge or severe AC line interference that
has corrupted the memory or micro-
processor.

If a reset does not solve the problem, con-
sult an authorized Harman Kardon ser-
vice depot.

Multiroom Operation

The 

MULTI

indicator on the front panel

display 

‚

will flash to indicate that the

multiroom system is turned on in the
variable mode, and that Source Linking
is in effect. With Source Link, any change
to the AVR80

’s input selection will also

change the feed to the remote room loca-
tions. If the input source is changed from
the remote room, the 

MULTI

indicator

will remain lit, but stop flashing.

If the AVR80

is turned off in the main

listening room, the feed to the remote
room will continue, although the

MULTI 

indicator will now remain con-

stantly illuminated.

To turn off the feed to the remote room
either while the AVR80

is still on, or

after it is turned off, press the 

button on the front panel. If the 

button is pressed while the AVR80

is

still on and the on screen video system is
engaged, a warning message will appear
on the video display (Figure #18) to
remind you that people may still be lis-

tening to the system in the remote room
location.

Remote Room Operation 
In this option, the remote room feed is
controlled by the use of an AVR80

com-

patible remote control. The remote com-
mands must be transmitted to the
AVR80

via a coaxial link connected to

the 

input on the AVR80

’s rear

panel.

Using the remote control in the second
room press the 

button to

turn on the remote room feed. This will
activate the multi room portion of the
AVR80

whether or not it may be on in

the main listening room. 

The initial feed to the remote room will
be the last station selected by the tuner.
Any other AVR80

input source may sub-

sequently be selected using the source
buttons on the remote control.

The initial volume at the remote room
will be the level established using the
options in 

SET UP MENU 2

.

If IR connections have been made to the
source playback equipment, it is also
possible to control the functions of those
units via the second room remote.
Consult with your dealer or custom
installer for additional information on
this type of installation.

When the remote room is controlling the
AVR80

via the IR link, the 

MULTI

indicator on the AVR80

’s front panel

will remain constantly lit.

NOTE: Whenever the AVR80

is in a

multiroom mode, the 

MULTI

indicator

will flash briefly whenever a command is
transmitted by the remote room location
and received by the AVR80

.
