RADIO TELEFONI
RT 4722

These specifications include i.e. ETS 300 162, ETS 300 338, IEC 945, IEC 1097-3 and IEC 1097-7. With thè Sailor RT4722 VHF DSC thè futi duplex technology is now available at a relatively little extra costand in thè well-known Sailor design.
Thè SAILOR RT4722 VHF DSC is Specially suitable for the professional maritime business.
Thè radio is an advanced DSC unit (class A) with ali thè necessary equipment boilt in to one compact unit Therefore it is thè ideai choice for ali areas with timited space as it is thè case on most vessels.
In a basic confìguration thè SAtt-OR RT4722 includes a transceiver unit and a handset.
Thè SPARC-bus interface, an advanced balanced data and AF interface, can be used to interconnect multiple contro! units and for exterior computer based control/programming options.
The maximum distance between transceiver unit and handset control unit may be 40 m in 12V DC installations, in 24V DC ihstallations up to 80 m.
Thè nominai system power supply is 12V DC.
By means of SAILOR N163S and/or N420, thè system can be powered from thè AC mains or a 24V DC battery.
A standard NMEA interface for connection to on-board navigational equipment is available in thè transceiver option connector.
