How do I install the Plantronics 510S?
A. On the bottom of the Plantronics 510S Base unit there are 2 ports. One has an icon of a “Handset” and one has the icon of a “telephone”. Unplug the “Handset” from the base of your existing telephone and plug it into the Plantronics 510S base unit where it has the icon of the “Handset”. Then take the short cable that came with the Plantronics 510S and plug it into the port on the base of the Plantronics 510S where the icon of the “telephone” is, Then plug the other end into where your “Handset” was on your existing telephone. Make sure the AC Power is plugged into the wall and then you can adjust the configuration setting to the clearest setting.
