Answer/End

We recommend that you install the Plantronics software. Though your headset will

operate without it, the soft ware is required in order to use the call answer/end function
with your Unif ied Communications application from the inline control. Go to

plantronics.com/software and click the Software Downloads tab. Follow the instructions

to download and install the software.

WARNING Do not use headphones/headsets at high volumes for an extended

period of time. Doing so can cause hearing loss. Always listen at moderate levels. See

plantronics.com/healthandsafety for more information on headsets and hearing.
