AVR10/AVR20/AVR30/AV40 Software Release Notes
– 1 –
Arcam, The West Wing, Stirling House, Waterbeach, CB25 9PB, UK
Required Equipment:
1. WiFi Internet router
2. Android or iOS device with Google Home App installed
3. Low capacity USB Memory stick 1GB to 4GB
4. Latest Unit Software. (see at www.arcam.co.uk)
5. Computer with Internet access.
WARNING – This Update will RESET all your settings.
*If updating from HOST 0.82 NET 239 (or lower) contact support at [e-mail] for assistance*
USB update procedure (Host and Net):
1. Confirm the current software version installed by pressing and holding the “MENU” button on the front
panel for 5 seconds. Scroll through the options checking HOST and NET versions comparing them to the
latest release versions.
2. Once you have confirmed the current installed versions exit the engineering menu.
If an update is required, locate the Unit Software files you download from our website on your computer,
unzip the folder (In windows right click the folder and select “Extract All”)
3. Once you have extracted the files copy the files ending in “.SWU” & “.FW” on to a freshly FAT32
formatted, clear USB Thumb Drive. After the Copying process finished, safely eject the USB Drive before
disconnecting.
4. Turn on your AVR making sure it is fully booted (> 40 Sec).
5. Insert the USB Stick in to the AVR.
6. Press & Hold INFO & DISPLAY simultaneously till the HOST Update process starts. This update will take
around 20 minutes, the AVR will prompt you to press “OK” to reset the settings & then enter standby
upon completion.
*As contents change between versions, restoring settings from a USB or secure backup is NOT recommended*
Alternative Update Method: Automatic Over-the-AIR Update
Now your AVR is fully up to date and setup within Google Home you can enable the Auto-Net-Update feature.
1. Go to MENU > HDMI SETTINGS > HDMI Bypass & IP = HDMI & IP ON
This Setting will prevent the Unit from entering the “low power standby” and will keep the NET Part of
the AVR active.
Once an update is released, your AVR will automatically download and install the NET update overnight.
2. You will be notified next time you start the AVR that an update is available. To manually start a HOST
update after an automatic overnight NET update, go to the engineering menu and select “Check for
Update” the HOST will now update.
This will take 90 to 100 minutes to complete. After the HOST has updated you will need to perform a
HOST reset by simultaneously pressing the INFO & MODE buttons on the front panel.
*It is worth noting that a HOST reset will delete all user settings configuration data. Also, Dirac
calibrations will need reloading on to the unit after the reset. As contents change between versions,
restoring settings from a USB or secure backup is NOT recommended*
Useful commands
•INFO & ZONE (SYNC on AVR10) = Full factory reset of both HOST and NET
•INFO + MODE = HOST reset (leaves Google Home and Network details intact)
Net can be individually reset from within the Web Configuration page
•INFO + DISPLAY = starts a USB update.
