Once free from the release bracket, the GlobalFix™ 406 will
automatically turn on if the water sensors are wet.
1.2.5 Alternately, the GlobalFix™ 406 can be manually activated by
lifting the thumb switch to a vertical position, sliding it toward
the antenna and pushing back down to the opposite side of the
EPIRB. Activating the beacon in this manner breaks off the
"Activation Indicator Plastic Pin" and allows the switch to
properly seat, showing the " z " symbol (ON).
1.2.6 Self contained long life batteries with a five-year recommended
replacement cycle provide power. See Factory Authorized Ser-
vice Center for replacement (Section 4.0 – Maintenance).
1.2.7 Self-test is initiated by momentarily lifting the thumb switch to
a vertical position and holding it in this position for at least two
seconds and at most 4 seconds. A beep and the simultaneous
lighting of the red LED indicate the initiation of the test. The
buzzer will beep an additional four times as the red LED lights
simultaneously. The green LED will then light, followed by a
flash of the strobe, indicating a successful test. During self-test,
an actual satellite message is transmitted while certain key
performance parameters are measured and recorded. The self-
test message is modified to prevent the satellite from forwarding
an alert message during self-test.
Warning : The following test should never be performed
more than once during the five-year life of the battery pack!
1.2.8 If the thumb switch is held in the vertical position after the
Self-test has finished, the buzzer will beep and the red LED will
light simultaneously. This beep and simultaneous red LED
indicates that the GPS has been turned ON and a live test of the
internal GPS has begun. At this point the thumb switch should
be allowed to return to its normal OFF position. The GPS will
remain ON until good navigation data has been obtained or until
10 minutes has elapsed. If good navigation data has been
obtained, the GPS will be turned OFF and the green LED will
light for 2 to 3 seconds. This navigation data is not saved for
use when the beacon is turned ON. A green LED indication is
proof that the GPS is functioning properly and that the beacon is
in a location or environment where it can receive the necessary
