• If the red and green LEDs flash together and alternate with the
strobe flash, the EG50 EPIRB has a valid GPS position which it
is transmitting regularly. This is the normal operating condition
which requires no user action.
• If the red and green LEDs flash at different rates, the EG50
EPIRB is attempting to obtain a GPS fix. If this indication
persists, it is advisable to move the EPIRB to a different
location; something may be affecting its ability to see the GPS
satellites.
The LEDs can give many other indications; these are principally for
diagnostic purposes.
4.5 Buzzer
The EPIRB contains a buzzer to give audible feedback.
When the EPIRB is activated the buzzer pulses rapidly (whilst the red
LED is ON continuously) as a warning that the EPIRB is about to
transmit. Once the first transmission is complete, the buzzer sounds
synchronously with the strobe.
The buzzer is also used to indicate the results of self-test.
