ESCRIPTION
D
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.
• The Helmet Microphone Assembly (P/N 10042902)
• 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.
Failure to follow the above Warnings can result in
serious personal injury or death.
• Misuse or abuse of the Helmet Communications
System, or the equipment to which it is attached,
or using this equipment in a manner or situation
not intended by the manufacturers may result in
damage to the Helmet Communications System.
• Evaluate this unit and any radio transceiver with
which it may be used. Be certain the unit is not
affected adversely by radio frequency energy.
• Evaluate this unit and any radio transceiver with
which it may be used as a sour
ence to other apparatus before entering a hazardous atmosphere.
• Ensure radio is at the lowest volume setting.
Control the volume for the Helmet Mic. and Ear
Speaker Assembly or Lapel Mic. with the volume
control on the radio.
Maximum head size of helmet suspension is
•
reduced when the Helmet Mic is attached. Adjust
suspension as required
