IMPORTANT:
In most countries the operation of an AIS unit is included under the vessel's marine
VHF license provisions. The vessel on to which the AIS unit is to installed must therefore possess a
current VHF radiotelephone license which lists the AIS system and the vessel Call Sign and MMSI
number. An MMSI number is required in order for the Quark-elec AIS CLASS B transponder to
operate. Please contact the relevant authority in your country for more information.
