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 PLB1 over water, tether the beacon to
your body or the life raft. Keep the PLB1 clear of water when
operating. When operating on land, place the PLB1 flat on the
ground if possible.

Keep your PLB1 laying flat with the antenna standing
vertically. Keep the area marked “GPS Antenna” free from
obstruction, which can interfere with the GPS
reception.
NOTE:
The PLB1 does not transmit an alert until approxi-
mately 50 seconds has elapsed. This allows time to
deactivate the unit if accidentally turned on.
