When searching for information, be aware that the brand is often referred to by different names. "Beta Three" is the official brand name, but "Beta 3" is a very common shorthand. You might also see references to "OmniSistem Beta 3," as OmniSistem appears to be a distributor or partner, particularly in European markets. The model name is consistently "U15a" (or "U15a-MP3" for the MP3-equipped version). Using all these variations in your searches ("Beta 3 U15a," "Beta Three U15a repair," "OmniSistem U15a") will yield the widest range of results. | Specification | Value | | :-------------------------- |
