The SARBE 6 Personal Locator Beacon is designed for use as a survival radio by civil or military aircrew. On activation, the unit transmits a continuous, internationally recognised, swept-tone radio distress signal in the UHF and VHF distress frequencies. It also provides two-way voice communications between the survivor and approaching rescuers.

The unit is activated by the removal of an operating pin - either manually, by a single action, or automatically, by such functions as liferaft inflation or ejector seat operation.

SImultaneous, omnidirectional transmission of both 121.5 MHz and 243 MHz signals then continues automatically for a minimum of 24 hours to facilitate detection by search aircraft or vessels, or by any other land, sea or airbourne installations monitoring these frequencies.

SARBE 6 can be tested quickly and simply before the commencement of a flight or at regular intervals by lifting a 'Test Lever' mounted on the side on the unit. A green or red light gives an instant 'GO/NO GO' indication.

An optional antenna extension is available for life preserver storage.On inflation of the life preserver, correct deployment of the antenna is automatically ensured, even in the worst survival environment at sea.

The SARBE 6 is waterproof to a depth of 10m (30ft) and the battery has an unused shelf life of 5 years when stored in continuous temperate conditions.

Fully approved by the CAA, and meeting NATO STANAG 3281, 5th edition, the unit is COSPAS/SARSAT compatible.
