EPIRB1 Pro USER MANUAL
7.1 Beacon Test
! Ensure the antenna is free and above the EPIRB1 Pro before commencing the test.
Fold the antenna back behind the EPIRB1 Pro as you replace it in the housing.
! Because the test transmits a short burst on the aircraft distress frequency of
121.5MHz, please only carry out this test in the fi rst fi ve minutes of each hour.
! It is recommended to test your EPIRB1 Pro once a month.
! The amber test result indicates the battery has been used for over one hour or
the recommended number of tests has been exceeded. The EPIRB1 Pro will still
operate normally in distress, but the battery should be replaced to ensure the full
operating life when your EPIRB1 Pro is needed.
To test your EPIRB1 Pro is functioning correctly, press and hold the TEST key for at least
one second. The red LED will come on to indicate the switch is depressed, followed by
the red LED fl ashing rapidly, indicating test mode is activated. The switch may now be
released. The strobe light will fl ash once (indicating that the 406 and 121.5MHz signal has
been transmitted).
After a short pause, the indicator LED will produce a fl ash sequence:
! This fl ash sequence is repeated a second time after a short delay and then the
EPIRB1 Pro will automatically turn off.
The number of green/amber fl ashes in each group indicates the number of hours the
battery has been used for as shown in the table.
