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 ca
-
bles 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.
