Can't seem to get my system to repeat. I'm out in the 'boondocks' with very few parts and a long way from a Radio Shack. Just hoping I don't need to buffer the COS somehow to get it to switch. </span><br></div><div style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:12px;"><div id="ecx:nl" tabindex="0"><img src="https://ssl.gstatic.com/ui/v1/icons/mail/images/cleardot.gif"></div></div><div class="ecxgmail_signature">John</div>
