Harman Kardon is pleased to offer
this software upgrade to improve the
audio and video performance of your
AVR 745. Unlike many consumer
audio products that are designed with
“fixed” memory, the Harman Kardon
®
AVR 745 features flash memory,
which makes it possible to upgrade
the unit’s internal software through a
standard USB port when required. To
install the upgrade, please follow the
instructions on this sheet. If you have
any questions, consult our Web site
at www.harmankardon.com.
Important Note:
This software is specially designed for
use with the Harman Kardon AVR 745
receiver. Use with any other models or
brands may cause damage to the product.
DO NOT USE THIS SOFTWARE WITH
ANY PRODUCTS OTHER THAN THE
HARMAN KARDON AVR 745.
System Requirements
To install the upgrade, you will need a standard
USB “Type A to Mini Type B” cable. The cable
supplied with your AVR 745 to connect the
TC 30 remote to a computer for programming
may be used for this purpose.
You will also need access to a computer that is
close enough to be connected to the
AVR being upgraded. The minimum system
requirements for the computer are:
• Processor: Intel
®
Pentium
®
II processor or
equivalent, or higher
• Operating system: Windows
®
2000 SP4
or higher, Windows XP or Windows
Vista
®
system
• Hard-drive space: 10MB available
• System RAM: 128MB
• CD-ROM drive (when using upgrade disc only)
• USB port
Installation Instructions
Upgrading your AVR 745 is easy, but for
the upgrade to work properly, it is important
to precisely follow the instructions below.
PLEASE READ THESE INSTRUCTIONS
CAREFULLY BEFORE PROCEEDING
.
• If you are using files downloaded from the
Harman Kardon Web site to upgrade the
AVR 745, use Windows Explorer or any
other file management program to locate
the folder where you have downloaded the
upgrade file. Click on the file named
“AVR745Upgrade.exe.”
When you do this,
the file will automatically unpack all of the
files needed to upgrade your AVR 745.
• If you are installing the upgrade from a
CD-ROM, insert the disc in your computer’s
CD-ROM drive.
• Upgrading your AVR 745 will erase all system
memories. This means that any configuration
settings or tuner presets that you have entered
will be lost. To make it easier to re-establish
the settings after completing the upgrade, you
may wish to write down your current system
configurations using the worksheets that are
included with this software package. To print
those worksheets, use Windows Explorer or
another file management program to locate
the
Worksheets.pdf
file in the directory where
the upgrade files have been saved. Click on
the file to open it with Adobe
®
Reader
®
soft-
ware and then print copies as needed.
• Make certain that the
Main Power
switch
(behind the front-panel door) on your AVR is
turned off, and then connect the USB cable
to your computer and to the jack on the
rear panel of your AVR.
• Press in the
Main Power
switch on your AVR,
but leave the receiver in Standby mode.
• Locate the directory for the downloaded
files or CD-ROM and click on the file named
“HK_Upgrader.exe.”
It should be easy
to recognize, as there will be a small
Harman Kardon logo near the file name,
depending on the display mode for your
file manager.
• A new window will open on your computer
screen when the Loader program starts.
Click
NEXT
to proceed.
• The next screen contains the End User
License Agreement that covers the software
upgrade. Please read this important docu-
ment, using the scroll bar on the right side
of the window to move down through the
copy. If you agree to the terms of the
agreement, click
I ACCEPT
to proceed;
otherwise, click
I DECLINE
to cancel the
upgrade and exit the Loader program.
• Enter the serial number of your receiver in the
spaces provided on the next screen, making
sure to enter any capital letters exactly as you
see them on the serial number label. Do not
enter the dash between the two parts of the
serial number, but do divide the number to
the left and right of the dash provided in the
on-screen boxes. Click
NEXT
after the serial
number has been entered.
• If the serial number is correct, the program
will proceed to a screen where you select
the type of upgrade. To properly load the
new software, it is important that the DSP
memory be upgraded first. Click
DSP
;
a screen will appear, with the model number
of your AVR and the upgrade type shown
at the top of the message window. Click
NEXT
to continue.
• On the next screen, click
BROWSE
to open
a file finder window so that you may select
the
“.DSP”
file to use for this upgrade. Click
on the file so that it is highlighted and then
click
OPEN
; confirm that the file name
appears in the window.
• Before proceeding to the next screen, you
must put the AVR 745 in a special DSP
Upgrade mode. To do this, press and hold
the
Surr Mode
and
Tone Mode
buttons on
the front panel. (
Surr Mode
is the first but-
ton on the left on the front panel;
Tone
Mode
is the first button on the left in the
row of round buttons below the flip-down
door on the front panel.) As you hold the
buttons, a DSP REBOOT message will briefly
appear in the lower line of the front-panel
display, followed by a DSP UPGRADE mes-
sage in the upper line of the display. When
DSP UPGRADE appears, you may release
the buttons. Click
NEXT
to continue.
