* Do not press any buttons or interrupt the mains supply during the upgrade, otherwise the HTS may become defective.
* Make sure that your Home Theatre System recognizes the USB storage device before you try to upgrade the firmware. You can verify this by copying an image file to the USB device and trying to reproduce it with the HTS.
* Use a FLASH based USB storage device (e.g. a thumbdrive) that complies with the Mass Storage Class protocol and has a capacitiy of less than 160 Gb. External hard disk drives (HDD) take a while to start up, which makes them unsuitable for a firmware upgrade.
* Make sure that that no other files are stored on your USB storage device. Files that do not belong to the upgrade package may cause the process to crash.
Proceed as follows to upgrade the firmware:
Important: Please remember to delete the upgrade files on the USB before you connect it again to prevent the set performing the upgrade a second time. Please make sure there is no disc in the tray before you perform the software upgrade.
Please contact Philips Consumer Care centre for technical assistance or additional information about your product if the upgrade failed.
