Anthem AVM 20 Technical manual

8. SOFTWARE UPDATING
The operational characteristics of the AVM 20 are controlled by software that can be easily upgraded via the
RS-232 port on the Rear Panel. New software can be downloaded from our web site, and then transferred by
connecting the AVM 20 to your computer’s serial port and running the Software Installer.
8.1 SOFTWARE VERSION IDENTIFICATION
If you want to see which Software Version is in your AVM 20, press STATUS. The display will show:
Please contact your dealer or visit the AVM 20 page on our web site at www.anthemAV.com to find the latest
Software, and any operating manual updates that go along with new versions.
8.2 SOFTWARE UPDATING VIA YOUR DEALER
To do this, you will have to take your AVM 20 to your Authorized Anthem Dealer. To save yourself time and
trouble, please remember to call your dealer first to find out if you should get the latest Software version, and
then arrange a time to install the update. Note: Your dealer may charge for this service.
8.3 SOFTWARE UPDATING VIA YOUR COMPUTER AND THE INTERNET
To update the Software through your computer, you will need the following:
•Access to the Internet.
•Serial cable – straight wired, with one end DB9 male for the AVM 20, and the other, DB9 female or
DB25 female for your computer. A similar looking null-modem cable will not work.
Typically, a cable length of up to 100 feet (33 meters) will work for a long distance connection to your
computer. You may also install this cable permanently to enable easy future updates. When it’s not
in use, disconnecting it either behind the computer or the AVM 20 is recommended, to prevent the
possibility of a ground loop.
Computer System Requirements:
•Win9x, NT, ME, 2000, or XP.
•1MB free space on the hard drive.
•Serial port. The Software Installer automatically detects the port being used (COM1 to COM4).
If your computer does not have a serial port but has a USB port, you will need a USB-to-serial
adapter (its driver program must also be installed on your computer).
Note: Before running the Installer, check the computer’s power management settings to ensure that the
Software Update does not get interrupted while running.

Software installation procedure:
1. Find out which Software version you currently have by pressing STATUS.
2. Go to the ANTHEM web site (www.anthemAV.com) and locate the latest AVM 20 Software version.
Proceed only if your version is a lower number, indicating that it is older.
3. Click on the download icon. You will be asked where to save a file called ‘avm20install.zip’ – save it
to your computer’s desktop.
4. Double click on ‘avm20install.zip’. If you computer tells you that the file cannot be opened, you can
download a program that can open the file through one of the links on the ANTHEM web site.
5. Drag or extract ‘AVM 20 Installer.exe’ and ‘Read Me First.txt’ to desktop. ‘Read Me First.txt’ lists the
latest software changes. You can now delete ‘avm20install.zip’.
6. Ensure that your current AVM 20 Setup configuration is saved (see section 7.4.11).
7. Turn off your AVM 20 and disconnect the power cord to prevent the possibility of a static discharge
when the serial port is connected. Tuner presets, speaker level settings, bass/treble, etc. are
automatically written to memory if the line voltage is disconnected or during a power failure.
8. Using the serial cable, connect your computer to the AVM 20 via the RS-232 port on the rear panel.
Updating does not require moving the AVM 20 or disconnecting it from your system, as long as you
can connect your computer to the RS-232 port.
9. Plug the AVM 20’s power cord back in and turn the rear panel switch on.
10. Double click on ‘AVM 20 Installer.exe’, then click on ‘Install Upgrade Now’. In a few minutes, the
installation and verification will be completed.
Restore Settings?
You do not need to Restore or Recall any settings after installing new software. The AVM 20 will retain the
settings that were in use before the update, except that the day and time will be set according to your
computer’s day and time settings – if re-adjustment is required, see section 7.4.1.
Troubleshooting:
If the Installer keeps returning a message that says ‘AVM 20 Not Found’ after several attempts, restore
Factory Defaults in the Setup Menu, try installing again, and reload User Settings once the new software is
installed. If that doesn’t work, make sure that the serial port on your computer isn't already being used by
another application, such a docking station for a personal organizer – you must go into the application that
is using it to turn off the serial port.

CANADA & USA
Anthem Electronics warrants to the original purchaser that each Anthem AVM 20 is free from defects in workmanship
and materials, during normal use and service, for a period of five (5) years from the date of sale (one year for the remote
control). This warranty is not transferable unless the product is traded-in with an Authorized Anthem Dealer. During the
warranty period, Anthem Electronics will repair or replace any defective components free of charge.
Warranty is void if the Anthem product is not purchased from an Authorized Anthem Dealer, if the serial number has been
removed, altered, or defaced, if the product has been operated or handled other than in accordance with the instructions
in its Operating Manual or otherwise abused, misused, damaged by accident or while in transport, tampered with,
modified, or repaired by anyone other than Anthem Electronics or an authorized Anthem Electronics service center. If
inspection by Anthem Electronics discloses that the repair required is not covered by this warranty, regular repair
charges shall apply.
Display products sold by an Authorized Anthem Dealer are covered under the same warranty terms, except that the
warranty period commences from the date of the dealer invoice, not the purchaser’s invoice, and cosmetic flaws, if there
are any, are excluded.
If a problem or defect is discovered in your Anthem product, please contact your Authorized Anthem Dealer. It is the
Dealer’s responsibility to determine the nature of the problem and arrange for the appropriate replacement parts, or the
return of the product to Anthem Electronics.
A Return Authorization (RA) number must be obtained from Anthem Technical Support before any product can be
returned to Anthem Electronics for any reason. The RA Number must be clearly visible on the outside of the shipping
carton for Anthem Electronics to accept the return. Product shipped to Anthem Electronics without a RA Number will be
refused and returned to the sender, freight collect. Product shipped to Anthem Electronics for repair must have shipping
and insurance prepaid by the sender, be packaged in the original carton and packing material, and should be
accompanied by a written description of the defect. Anthem Electronics will accept no responsibility for any damage
occurring to a product that is shipped in any type of carton and packing material other than the original carton and
packing material.
To receive service under warranty, an accompanying copy of the original sales receipt is required. Product repaired
under warranty will be returned with shipping and insurance prepaid by Anthem Electronics (within Canada and USA
only). All other repairs are subject to charges for labor, parts, return shipping, and insurance.
Disclaimer of Liability
Under no circumstances does Anthem Electronics assume liability or responsibility for injury or damages sustained in
the use or operation of Anthem products, or for damages to any other connected products.
In no event shall Anthem Electronics, its agents, representatives, or employees, be responsible for any incidental or
consequential damages. Some jurisdictions do not allow limitations of incidental or consequential damages, so this
exclusion may not apply to you.
Anthem Electronics reserves the right to make design changes or improvements to products without any obligation to
revise prior versions. All specifications are subject to change without notice.
On the expiration of the warranty period all liability of Anthem Electronics in connection with the product shall terminate.
This warranty constitutes the only warranty applicable to products sold by Anthem Electronics. No other warranty or
condition, statutory or otherwise, expressed or implied, shall be imposed upon Anthem Electronics, nor shall any
representation made by any person, including a representation by a representative or agent of Anthem Electronics, be
effective to extend the warranty coverage provided herein.
Frequently Asked Question: Is there a warranty on trade-ins?
The balance of the warranty can be transferred on used product only if the product is traded-in at an Authorized Anthem
Dealer, who may resell the product with the remaining warranty if it is cosmetically acceptable, in perfect working
condition, and has not been internally or externally altered in any way.
INTERNATIONAL
Outside of Canada and USA, warranty coverage terms are set and maintained by the Authorized Anthem Distributor, not
Anthem Electronics. Exact terms and conditions may vary. Anthem Electronics will provide warranty replacement parts
to the original purchaser of the product, via the distributor, for a period of five (5) years, via surface mail. Additional
courier freight charges will apply.
