Voice Activated Intercom (VOX) feature allows "hands free" com-
munication between headsets connected to the UltraSound unit.
Start speaking and the intercom turns on instantly to relay your
message clearly to the other headsets. Stop talking and it turns off
to reduce background noise.
Up to Four Headset Positions can be connected to the UltraSound
unit models UT-4S and UT-4D. Up to six for models UT-6S and UT-6D.
More headset positions can be achieved by wiring additional jacks in
parallel. Only one headset, however, can be plugged into paralleled
jacks at one time. In the case of the Driver, he plugs his headset into
his jack while driving. He then unplugs and plugs into the Driver's
Auxiliary jack when he arrives on scene.
