From dis tres s s ignal to res cue
Distress beacons are compact devices that, in a critical situation, can
become the only link between you and rescue services. They transmit
your location to satellites and coordinate international rescue
operations.

activated manually only.
These devices are used only in life-threatening emergencies — when all other means of communication are exhausted
and immediate assistance is required.

One Signal — A Life Saved
The beacon transmits your unique identifier and precise coordinates, initiating a coordinated international rescue
operation.

4.

Step 1 — Beacon Activation
Manual Activation
The owner removes the protective cap and presses the activation
button. Ideal for PLBs and controlled situations.
Automatic Activation
EPIRB is released from its bracket when the vessel is submerged,
floats to the surface, and automatically activates upon contact with
water.
Typical Scenario
Vessel sinks → beacon is released → floats vertically → begins

S tep 5 — Res cue Coordination Center
01
Receiving the Alert
The RCC (Rescue Coordination Center) receives distress signal data, including
coordinates and beacon identifier.
02
Regis tration Verification
The operator checks the database: who owns the beacon, which vessel, contact phone
numbers for the owner and relatives.
03
Contacting the Owner
If possible, the owner or their contacts are reached to confirm the emergency situation.
04
As s es s ment and Dis patch
The RCC determines urgency, selects appropriate rescue resources, and dispatches
teams to the scene.

Step 6 — Search and Rescue Operation

Detection Technologies
121.5 MHz — final stage homing
AIS — directed search
Strobe light — visual detection
Rescuers use a combination of technologies to accurately determine your
location and ensure rapid evacuation.
