PROGRAMMING THE REMOTE 57

Additional Notes on Configuring and
Operating the Remote:
• When the remote is being programmed, it will

automatically time-out if no button is pressed
within a thirty-second period. The message
shown in Figure 77 will appear briefly, and the
remote will then exit the feature being pro-
grammed and any data entered will be lost.

• The programming or configuration process may 

also be stopped at any time by pressing the
Clear Button

#. The message shown in

Figure 77 will appear, the data entered in the
current process will be lost and the remote will
return to normal operation. Any process that
was underway when the button will be pressed
must be re-started.

• Extensive use of the programming, learning

and configuration functions of the remote may
consume significantly more battery power than
normal remote operation. While the batteries
should last for four to six months in normal
operation, you may find that they need to be
changed sooner after the remote is pro-
grammed for the first time.

• When the batteries approach a level below

which the remote will not function, the
remote’s LCD screen will display a 

LOW BAT-

TERY

warning as shown in Figure 78. We

strongly recommend replacing the batteries as
soon as this message appears to avoid the loss
of programming and configuration settings.
These settings are not lost when the batteries
are changed quickly.

• The remote has a built-in backlight that may be 

activated by pressing the Light Button

Q.

This button is made from a special “glow”
material so that it is easier to find in dark
rooms. This glow feature does not consume any
electricity, but the glow will fade when the
remote is kept in a dark location for an extend-
ed period of time. The “glow” feature may be
restored by placing the remote in normal room
light for a few hours.

• The remote’s backlight will remain lit for

approximately five seconds after the Light
Button

Q is pressed, and it will stay lit for

another five seconds if any key is pressed while
the backlight is on. You may keep the backlight
lit by holding the Light Button, but extensive
use of the backlight will reduce battery life.

• The LCD display will remain on for ten seconds

after a key is pressed and then turn off to con-
serve battery life.

• When any button is held for more than thirty

seconds the LCD will turn off and the remote
will stop transmitting the codes to conserve
battery life.

58 TROUBLESHOOTING GUIDE

In the rare case where the unit’s operation 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 AVR’s entire system memory includ-
ing tuner presets, output level settings, delay
times and speaker configuration data, first put
the unit in Standby by pressing the System
Power Control button 2. Next, press the
Surround Mode 5 and the RDS ^ buttons
simultaneously.

The unit will turn on automatically and display
the 

RESET

message in the Main Infor-

mation Display ˜. Note that once you have
cleared the memory in this manner, it is necessary
to re-establish all system configuration settings
and tuner presets.

NOTE: Resetting the processor will erase any
configuration settings you have made for
speakers, output levels, surround modes, digital
input assignments as well as the tuner presets.
After a reset the unit will be returned to the
factory presets, and all settings for these items
must be reentered.

If the system is still operating incorrectly, there
may have been an electronic discharge or severe
AC line interference that has corrupted the
memory or microprocessor.

If these steps do not solve the problem, consult
an authorized Harman Kardon service depot.

APPENDIX  59

The three tables in this section show the factory default settings for the Video Inputs, Video Sources and Video Display Aspect Ratios. These tables give you
the complete picture on the AVR 7300’s initial settings. You may then decide whether any item needs to be changed so that it is more appropriate for your
specific installation. Any of the settings shown may be changed as shown in the pages of the System Configuration section of this manual (pages 19–32).

Once you have installed the AVR 7300 and found the combination of audio and video settings that works best in your system, we recommend that you
record them here to provide a written backup of your system’s configuration. These worksheets make it easy for you to reestablish your settings if the
internal memory is lost due to an extended power outage or reset due to a system upgrade, processor reset or other service to the unit. Additional copies of
these worksheets may be downloaded from the Harman Kardon Web site at (www.harmankardon.com/).
