Operation
Downlead Cables
Most models of the NoizeBarrier
®
TAC headset have hard-wired downlead cables
ready to attach to your push-to-talk cable.
However, Models V4-10995FD and V4-11042FD have connectors for the downlead
cables to allow you to remove cables when not in use. To attach a downlead cable to
these models, simply line up the cable with the connector on the headset and push to
lock it in place. To release, pull down on the collar on the cable to easily pull the cable
away from the connector.
