Hey Everybody,

I've a message from time to time after switching on the HTS7540. By pressing the volume up or down button the following message comes up in the display and i can switch between them "U551, U555, APAC93, APAC98 and EU12". I've no idea what the are for. I've also contact the Philips support in Germany but no response.
Can anyone help me with this problem. Because during the message is shown I can't do anything with the HTS7540. The only action to keep the unit runnig is disconnect the cable and reconnect it.
Thanks for any support on that.
