Self-Test & Inspection; Short Self-Test - mcmurdo Smartfind G8 AIS User Manual

7.2 Self-test & inspection
The EPIRB has a built-in self-test
capability that can be used as a
confidence check. This self-test confirms
that the battery is healthy, that the GPS
receiver and distress transmitters are
functional and that the strobe light is
operational. The short self-test should be
performed monthly and not more than 12
times per year. It should be performed
during the first 5 minutes of the hour to
minimise disturbance on the emergency
channel.
