The acoustic horn, circled in the diagram, enables ultrasound proximity pairing. Never block the acoustic horn. For best performance, point it away from the floor and from other sound-absorbant surfaces, such as carpets or fabrics.

Operating Temperature

It is normal for your Webex Share to be warm when you touch it. The external operating temperature is 32° to 140°F (0° to 60°C).

Webex Share power requirements are:

  • USB type -C power

  • 5VDC

  • Power consumption is 3.2 W maximum.

Resolution and Framerate

Webex Share has a maximum capability of 1080p resolution at 30 fps and 4.0 Mbps bandwidth.

Display Requirements

If the TV is recessed into a wall, we recommend these clearances between the TV and the surfaces around it:
  • 3 in. (7.62 cm) all the way around the TV

    These clearances help to optimize proximity pairing with Webex.
