The Dual Communications NATO Adaptor Cable allows for Safariland® / TCI™ dual communications headset products, such as the Liberator® III and Liberator® V, to interface using any push-to-talk that accepts the NATO plug (U174). The adaptor cable can also be used to convert a Safariland or TCI dual communications headset product into a single communications headset. This feature allows a dual comm headset to be plugged into any NATO compliant push-to-talk, normally for aircraft intercom or separate single comm PTT use.
