The DSC test requires that a valid MMSI has been programmed into the MOB.
See section 4 for instructions on programming the MMSI.
The DSC test should only be carried out a maximum of two times a year to
minimize battery consumption.
7.3 AIS transmission test
To initiate an AIS transmission and GPS test, press and hold the “TEST/OFF” key. The red
LED will start flashing and then become steady after five seconds. After a further five
seconds, the LED will start flashing slowly. Release the key. The LED will give a long red
flash followed by a short green flash until GPS lock is achieved. After GPS lock is obtained,
the MOB will transmit a single burst of AIS messages indicated by eight short flashes of
the green LED. The strobe will flash and the indicator LED will flash green or amber to
show a pass, or red to show fail status, as indicated in Table 1. The MOB will then
automatically turn off.
After a successful test, the message “MOB TEST” will be displayed on a suitable AIS
receiver or plotter display.
The AIS/GPS test should only be attempted with a clear view of the sky.
The AIS/GPS test should only be carried out a maximum of three times a year to
minimize battery consumption.
