    INTRODUCTION AIS Tests The test box is capable of testing AIS transponders by making frequency measurements and power measurements on CH 70, AIS channel 1 or AIS channel 2. It is possible to check the GMDSS communication on CH 70 by requesting reporting of Position, Length, Course, Name/Identity, Speed, Power or Ships beam. AIS communication is checked by sending data to an AIS transponder or receiving data from an AIS transponder. The test box is able to simulate a ship appearing at four different positions, relative to the AIS transponders position. The test box can also be used for the testing of AIS-SART emergency beacons, as it can receive and decode test calls on AIS channel 1 and 2. GMDSS Tests The test box can check DSC signals transmitted on any of the 6 distress frequencies on MF/HF and on VHF CH 70. The test box can send either a GMDSS distress signal (all ships call) or a selective test call addressed to a particular MMSI number. The calls can be sent on any of the 6 distress frequencies on MF/HF as well as on VHF CH 70. Furthermore, the test box can send and receive DSC signals on the international calling frequencies 2177.0 and 2189.5 kHz. The test box measures and displays the mark/space frequencies of the received DSC-signals. When used as an ordinary frequency counter the test box measures frequencies in the range 0.4 MHz to 475 MHz. On VHF CH 6 the test box can measure the deviation on a received signal. The test box is able to measure the transmitted and reflected power on any VHF channel, and also to test the sensitivity of the receiver part. For the testing of Navtex receivers, the test box can send Navtex signals on 490 kHz, 518 kHz or 4.209,5 kHz. The test box can also be used for control of signals from EPIRBs, as it can receive and decode test calls on 406.025 / .028 / .037 /.040 MHz as well as receive the 121.5 MHz homing signal. All measurements can be monitored on the LCD display and results are stored in the test box memory from where it can be transferred to a PC for subsequent printing.

    This manual is intended for use with the GMDSS-AIS test box model as well as for the GMDSS-only model. Users of the GMDSS-only model are kindly requested to disregard the sections concerning AIS tests.
