USO – Audio Handset
The USO audio handset comes with an integrated reed contact that can be wired into our media players to start and stop playback. It does this when it is lifted or replaced on the magnetic holder.
- Handset on holder: Contact open
- Handset picked up: Contact closed
Please see the AP01 or MP01 pages for further information on how to program this feature.
Wiring your USO to our Media Players
- White/Brown – Audio Signal
- Yellow/Green – Reed Contact
For mono handsets like the VIA and USO, one side of the audio needs to be wired to ground (GND)
Note: If you do not wish to use the auto-start function of your handset, then the yellow and green wires should not be wired into the media player.
