I have just upgraded to a 6400 from a 3000. I would like to use a Yamaha CM500 Headset with the 6400 it is what I used with the 3000. What mic would I select from the choices given? I had to use the battery pack with the 3000 yes or no with the 6400. Would I also have to turn on the Bias or leave it off. Appreciate any guidance.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
