Link Microtek has today announced an enhancement of its Azdec infra-red mobile communications system with the introduction of a new battle-helmet headset that offers active noise reduction. Designed to ensure that clear audio communication is maintained in even the noisiest of environments, the new headset is particularly suitable for naval ‘force protection’ personnel stationed on a ship’s bridge wings and can also be used wherever an Azdec system is deployed on land.

Providing totally secure, short-range voice communications using infra-red signals, Azdec systems enable personnel to roam freely from their base positions, unhindered by any trailing wires. There are no RF emissions and the infra-red signals cannot be detected by any conventional method, so it is impossible for anyone to eavesdrop on what is being said.

The new headset incorporates an Azdec transceiver employing low-level infra-red digital encoding technology, together with noise-cancelling circuitry to eliminate any disruptive background noise.

Compatible with a variety of helmets, the headset combines rugged construction with a comfortable, ergonomic design featuring dual-seal foam ear cushions, adjustable nylon straps, a padded stainless-steel napeband, an easy-to-position boom microphone, control module and rechargeable battery pack.

There is no need to remove the helmet when putting on the headset or taking it off, and both the boom microphone assembly and the ear cushions can be replaced in the field.

As the headset only transmits very low power infra-red signals, it carries a Class 1 product designation as defined by the EN 60825-1 standard, which means that it presents no ocular or other health hazard to users.
