Link Microtek has introduced a new single-sided headset for users of the company’s AZDEC infrared (IR) mobile communications system, which provides totally secure short-range voice communications on board naval vessels while allowing operators to roam away from their base positions, unhindered by any trailing wires.

Particularly suitable for officers stationed on a bridge or in an operations room, the 110525/202A headset enables users to clearly hear any activity or spoken commands in their immediate vicinity while at the same time communicating with other personnel via the AZDEC IR system.

The new monaural headset consists of an adjustable headband, a single earpiece, a flexible boom microphone with built-in noise-cancelling technology, a padded side support and a standard AZDEC IR transceiver. There are no RF emissions and the infrared signals cannot be intercepted by any conventional method, so it is impossible for anyone to jam the transmissions or eavesdrop on what is being said, according to the company.

The low-level IR digital encoding technology at the heart of the system is completely immune to radio, radar and electrical noise – even severe energy pulses – and has no effect on sensitive electronic equipment, flammable atmospheres or munitions. In addition, it carries a Class 1 product designation as defined by the EN 60825-1 standard, which means it presents no ocular or other health hazard to users.


Capable of providing secure multi-channel communications for areas of up to 10,000 square metres, an AZDEC system typically includes a base station, multiple headset/control units, a central battery-charger unit and 20-30 fixed IR antennas.
