All checks should undertaken should be done so by the primary operator who is registered in the GMDSS logbook. Each test should be noted in the GMDSS logbook.
Daily (when vessel is being used):
DSC internal tests (VHF)
Reserve source of energy checked on load with a voltmeter, most GMDSS stations have a voltage reading display panel, if it is below 22v it needs to be charged.
Check printers have ink and paper
Check clock against time ticks
Radio logbook is signed by the Master
Weekly:
MF External test on 2187.5 (call coast station on its MMSI # from ALRS Vol 5)
Survival craft/grab bag handheld VHF test (not on Ch 16, use 15 or 17) but do not use the sealed lithium battery, have a spare battery to use for testing purposes.
Monthly:
Antennas - free of corrosion, no loose connections.
EPIRB - self test, expiration date on battery and HRU and bracket, external check for damage (mounting, shell).
SART - signs of damage, battery expiration date, self test, test against radar for concentric circles.
24v Batteries (reserve source of energy) - check securing, connections, well ventilated compartment, check specific gravity of electrolyte with hydrometer.
