The 6000 and Beocom 2 are the two system phones, soon to be joined by the Beocom 5. </p> <p>You can tell a Mark 2 6000 by the fact it has a socket for the Earset on the top - a hole with 3 brass contacts on one side and one on the other. The Mark 1 has two round plastic circles on the same place.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/227570.aspxSun, 20 Sep 2009 10:45:11 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:227570leighdancer0https://archivedforum.beoworld.org:443/forums/thread/227570.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=227570<p>Hi all B &amp; O lovers.
