Use in "automatic trigger" mode
To use the beacon in "automatic trigger" mode, following the instructions below:
1. Attach the beacon to your life jacket using the strap clip or mouthpiece clip (see page 19-20)
2. Attach one end of the gasket in the hole provided on the beacon' s red antenna cap
3. Attach the other end of the gasket to a strap or fixed attachment towards the bottom of the jacket.
The gasket must be taut and placed in vertical alignment ith the beacon
4. Arm the beacon and close the jacket
Caution: If your jacket is not being used or is in storage, position the arming clip facing upwards
(cap blocked) to avoid accidentally triggering the beacon when you handle or transport your
jacket. The gasket must be taut, but not too much to prevent it from being triggered at the wrong
moment when you arm the beacon before going out to sea.
In a man overboard situation, the jacket will inflate in just a few seconds. The gasket will become taut
when the jacket is blown up, and will make the cap slide downwards, freeing the antenna. The antenna
cap will be ejected after sliding for about one centimetre and the beacon will start to emit your distress
signal and GPS location.
What happens when the beacon is activated (in open-loop mode)?
The buzzer emits a sound signal as soon as an AIS or DSC message has been sent by the beacon. The
beacon transmits 8 AIS messages per second, and 1 DSC message every 5 minutes (then every 10
minutes after 30 minutes). After each DSC transmission, the beacon waits for potential
acknowledgement from the on-board VHF for 2 minutes. Acknowledgement may come from:
• Either the boat's VHF, programmed into the beacon for the first 12 minutes in closed-loop mode
• Or the CROSS surveillance and rescue centre in closed-loop mode, or after 12 minutes in open-loop
mode
Once the beacon has been activated:
• The white LED flashes twice every 2 seconds
• The red LED flashes twice every 2 seconds, so long as the GPS position has not
yet been detected by the beacon
• Once the GPS position has been detected, the red LED will stop flashing and the white one alone will
continue
• If the GPS position was lost, the red LED will flash again once every 2 seconds
until the GPS signal has been recovered
