The Helmet Communications System allows a user to
communicate clearly and easily over a hand held portable
radio or truck system while wearing a helmet.
The Helmet Communications System consists of two
main components that attach to the user radio.

• Lapel Microphone or optional Basic PTT (Push-ToTalk) with the specific Radio interface connector.
Note: To complete the system the user must select and
purchase the proper Lapel Microphone or Basic PTT
(Push-To-Talk) unit that fits their specific radio.
When the helmet assembly is connected to the Lapel
Microphone the communication is the same as with the
Basic PTT interface.
