!
Because this test transmits a short burst on the aircraft distress frequency of
121.5MHz, please only carry out this test in the first 5 minutes of each hour.
!
The battery must be replaced either prior to the expiry date shown on the rear
label or after the EPIRB3 Pro has been activated.
!
If, during a self test, the LED flashes magenta or amber the EPIRB3 Pro may
not have sufficient energy to operate for the specified 24-hour period. Battery
replacement is recommended.
NOTE: The flash sequence will be repeated after a short pause and then the EPIRB3
Pro will automatically power off.
7.2.4 AIS Test
Two AIS transmissions will occur during a Functional Test indicating “EPIRB TEST” on AIS
receivers within range.
!
To visualise an indication of a successful AIS transmission during test always
ensure the AIS receiving unit is configured to react to EPIRB Test signals.
