TECHNICAL

 Salvare 4 is housed in two separate cabinets for installation flexibility.  One cabinet contains the 500 KHz and 2182 KHz transmitter which also has an integral radiotelephone alarm signal generator. The second cabinet contains the 8364 KHz transmitter, the receiver, the automatic keying device, a charging control unit  and stowage for the handset.and Morse key. These cabinets are fitted with removable covers which protect the controls and keep the entire equipment watertight when not in use. Quick release latches permit easy removal in an emergency.

The number or operating controls have been reduced and a system of numbered controls together with an explicit , step-by-step, operating instruction card enable the equipment to be used by survivors having no previous knowledge of the equipment. To further assist in distress situations, the Salvare 4 is provided with a self-supporting mast antenna fitted with a novel switching  unit which enables one person to erect the antenna to the operating position in safety even in adverse  conditions. This antenna is loaded so as to enhance performance on the distress and safety frequencies of 500 kHz, 2182 kHz and 8364 kHz on which the Salvare 4 operates. In addition, the Salvare 4 will operate on any type of wire, whip or mast antenna normally fitted in  lifeboats, although because of its improved performance over rigged wire antennas the mast antenna provided is more effective. The equipment can be connected, via a quick-release cable, to the ship's supplies  or charging the lifeboat batteries  and energizing the anti-condensarion heaters  which are fitted in each cabinet.
 

The station operates over a wide temperature range from - 15°C to + 55°C and  is tested to ensure operation at high humidity. The cabinets are fitted with shock absorber mounts to protect the equipment against the effects of rapid launching of lifeboats and the pounding which can be experienced by such lifeboats in adverse weather conditions. Salvare 4 meets IMCO recommendations as defined by  the British Home Office specification MPT 1213, the only other approved equipment being its predecessor, the Salvare 3.
