======Speakerphone Info======

====PolySync 40=====
(Thanks to BK)

=====Using two 40's in a meeting=====
Assuming you have charged them up.

  - Turn on both 40's (see: power button on narrow side, button on the right)
  - Both will tell you they're powered up and the state of the battery.
  - Press and hold for a couple of seconds the Link button {{lctg:polysync40_linkbutton.png}} on both 40's (see: link button on narrow side, button on left)
  - Hear “connection successful” and LED flashes white on both speakerphones means linking is successful.

Now, you need to connect one of the 40's to the computer in the room that'll be connected for the audience.  Call this "Audience PC".

  * If Audience PC has Bluetooth: 
    * Put Audience PC into Bluetooth search mode
    * Go to one of the 40's and press the Bluetooth icon on top of the unit (left side)
    * Make sure Audience PC sees the 40 and connect to it.
  * If Audience PC does not have Bluetooth
    * Using the intrinsic cable on the 40, connect to USB on the Audience PC.

The speakerphones are now set and ready to be used for both microphone and audio speaker.
  * Tell the Audience PC to use the PolySync 40 as its speaker
  * Start Zoom and tell Zoom to use the PolySync 40 as its microphone

Viola, you're all set. 

====Usage in a conference room====
  * Position one of the units near the main presenter.  This is the USB connected device or the one paired with the audience PC.
  * Put the other in the middle of the audience seating area.  This can easily be picked up and moved around to be closer to any audience speaker.
  * Make sure that both speakerphones are aligned so that they are parallel to the front of the room and parallel to each other.

====Tips/Tricks====
  * When moving a unit, hold it by the edges.  This way you will avoid pushing any of the buttons which might mute the mic or change the speaker volume.
  * A charge should last for many hours longer than any meeting.  It's wise to charge them up after a meeting.
