a fix is obtained, the green LED will flash quickly three times.

Each time a 406MHz transmission is made the LED will flash
quickly five times; green for transmission with a GPS position
and red for a transmission without a position.

When operating the PLB over water, tether the beacon to
your body or the liferaft. Keep the PLB clear of water when
operating. When operating on land, place the PLB flat on
the ground if possible.
