Having trouble with VOLUME?  Check these controls on your PC and Promethean ActivPanel to adjust volume:



First, on the front of the Promethean ActivPanel, there are  <  >  buttons to turn it's volume up/down, or you can use the Promethean remote to do this.



On the computer, there are several things that may need to be checked...

Start with the Windows volume control. It's located in the lower right system tray, near the Windows time/date. 

It looks like a little speaker, just click to raise/lower.




If the speaker icon is not in the tray, click the ^ arrow to expand hidden tray icons...



There may also be separate volume controls within the program/website you are using: 


::: Windows Media Player has a volume control that's independent of your system volume


To the right is the volume slider; clicking the speaker icon will mute/unmute audio from WMP.



::: YouTube has similar volume controls at the bottom left of the video frame: 

a volume slider...



If YouTube volume is muted, the speaker will have an "X" beside it.

Clicking the speaker will mute/unmute YouTube audio.



Checking these areas should help you locate any low level or muted controls.
