7.3.1.2 Power Test Burst
Using the following switch sequence the ELT operator can send out a test 406 MHz burst to
ensure the antennas are operating correctly.
CAUTION: The ‘Power Test Burst’ Test uses battery power and as a result if you choose to
perform more than the recommended twice yearly testing early battery replacement may be
required.
CAUTION: This test should only be performed annually to conserve battery power. This can
only be done in the first 5 minutes of any UTC hour and can be performed a total number of
10 times over the lifetime of the battery pack.
Place the ELT locking Master Switch in the “ARM” position and wait 5 seconds to begin
test or with the ELT already in the “ARM” position, press [”ON” , ”ARM”] , [”ON” ,
”ARM”] , [”ON” , ”ARM”] (within 5 seconds) at the Remote Switch.
Wait 30 seconds for the Test Burst (LED will flash twice every 5 seconds during this wait
period)

*For every Red Flash the buzzer will sound.
Note : If the operator has performed the toggle sequence too quickly it will be ignored and the
beacon will automatically perform an “ARM” test and power back down to await another
activation. When performing the test toggle sequence it is advised to observe a 0.25-0.5 second
remote switch “ON” time. Please note that the remote switch is a momentary type switch and
therefore the operator does not need to actively move the switch to the “ARM” position but
rather allow the switch to spring back into the default position.
