Error codes, Pre-MK3

I've got a flashing list on my Pre-MK3 Subwoofer. What does it mean?

Error codes on the pre-MK3 models assist in the diagnosis of errors. There are a wide variety of codes which can tell you more about why your amp may not be creating sound. This applies to all TLL14-XXXXX serial numbers. 

A PDF of this information is attached to this article.

Should you find your error code is "Service Required" please raise a ticket for personalized support.
