Plantronics charging cradle for Savi W710, W720, W410 or W420. If you already have a charging base for one of the models above, then you don't need to order this part. The only reason to order this is if you are ordering a second standalone headset (in which case you will also need the standalone base
shown below so that you can plug it into power), or if you want to change headset styles from another W700-series model. In the latter case, your existing charging cradle will simply snap off your existing base. Snap this one in its place and then you can use a W710 or W720 headset instead of the style you originally purchased. Questions? Please feel free to give us a call.
