Harman Kardon is pleased to offer this software upgrade to improve the audio and video performance of your AVR 247 or AVR 347 by updating its internal operating system and video-processing software. Unlike many consumer audio products, which are designed with “fixed” memory, these Harman Kardon® products feature flash memory that is upgradeable through a standard RS-232 serial port.To install the software, please follow these instructions. If you have any questions, consult our Web site at www.harmankardon.com. Important Note: This software is specially designed for use with Harman Kardon AVR 247 and AVR 347 receivers. Use with any other models or brands may cause damage to the product. DO NOT USE THIS SOFTWARE WITH ANY OTHER PRODUCTS. System Requirements To install the software upgrade, you will need to purchase a standard RS-232 connection cable. Do not use a “null modem”cable,as it uses connec- tion links that are not compatible with your AVR. If the computer you plan to use for the upgrade is not equipped with a serial port, we have found that many name-brand USB-to-serial-port adapters will provide the needed connection. We cannot guarantee that all such adapters will work. You will also need to have 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® (for Windows 2000 or Windows XP, your system may require you to have “administrator” user rights) • Hard-drive space: 10MB available • System RAM: 128MB • CD-ROM drive (when using the CD-ROM version of the program) • RS-232 serial port Installation Instructions Upgrading your receiver 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. • Upgrading your unit will erase all system mem- ories.This means that any configuration settings or tuner presets that you have entered will be lost.To make it easier to reestablish the settings after completing the upgrade, you may wish to write down your current system configurations using the worksheets that are part of this soft- ware 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,® and then print copies as needed. • Press in the Main Power switch on your AVR, but leave the receiver in Standby mode. • If you are using files downloaded from the Harman Kardon Web site to upgrade the AVR, 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 HKAVRupgrade.exe. The file will then automatically unpack all of the files needed to upgrade your AVR. • If you are loading the upgrade from a CD-ROM, insert the disc in your computer’s drive. • Locate the directory for the CD-ROM or the downloaded files and click on the file named “HK_Upgrader.exe.” It is easy to recognize; depending on the display mode for your file manager, the icon will be a stylized version of the volume control knob on your AVR. • A new window will open on your computer screen when the Loader program starts. Click “Continue” to proceed. • You will be reminded to record your receiver’s settings if you have not already done so. Click “Continue” to proceed. • The next screen contains the End User License Agreement that covers the software upgrade. Please read this important legal document, 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 this license agreement” and then click “Continue” to proceed. Otherwise, click on “I do not accept this license agreement” to cancel the upgrade and exit the Loader program. • When the screen changes, you will be prompted to enter the directory location where the files for this upgrade are located. Click “Browse” to open a file-finder window, and then navigate to the correct directory. When the location is correct, the file names will automatically appear in the “Current Selections” window. Click “Continue” to proceed. • Following the instructions on the next screen, connect the serial cable to both the AVR and your computer (or the USB-to- serial-port adapter, if used). Next, use the pulldown tab to select the serial port used for the connection between your computer and the AVR. If there is only one serial port, the most common setting is “COM 1,” but if there are multiple ports, if you are using a laptop in a docking station or if you are using a USB-to-serial-port adapter, you may have to select a different COM port. Depending on your computer system, you may have to return to this screen and choose a different port if the one originally selected does not connect properly. When a COM port has been selected, click “Continue” to proceed. HARMAN KARDON ® AVR 247/AVR 347 SOFTWARE UPGRADE INSTRUCTIONS
