2. Key Features
- AIS (Automatic Identification System): Transmits a distress alert on VHF frequencies, detectable by vessels with AIS receivers or plotters within a 5-mile radius under optimal conditions.
- RLS (Return Link Service): Provides confirmation to the beacon owner that the emergency distress signal has been received by Search and Rescue authorities.
- NFC Technology: Enables easy access to beacon data via a mobile application, displaying battery life, test results, activation time, and detailed GNSS test information, including map and accuracy.
- Infrared Strobe Lights: Ensures clear target identification during nighttime or low-visibility conditions, aiding rescue efforts.
- Waterproof and Buoyant Design: Engineered for marine environments, featuring a durable, waterproof, and buoyant casing.
- Extended Battery Life: Equipped with a 10-year battery and providing 48 hours of operational battery life in emergencies.



3. Setup and Registration
3.1. Registration
Before use, your GLOBALFIX™ V5 EPIRB must be registered with the appropriate national authority (e.g., NOAA in the United States). Registration is a critical step that links your EPIRB to your vessel and emergency contact information, ensuring that rescue services have the necessary details in case of activation. Follow the instructions provided with your EPIRB for online registration.
3.2. Mobile App Connection (NFC)
The GLOBALFIX™ V5 features Near Field Communication (NFC) technology, allowing you to connect your EPIRB to a smartphone app for diagnostics and status checks. This feature provides convenient access to vital information without activating the beacon.
- Download the official ACR product app from your smartphone's app store.
- Simply place your smartphone adjacent to the GLOBALFIX™ V5 EPIRB. The app should automatically open and display beacon status information.
- The app provides details such as current battery life, the number of beacon tests completed, and the total time the EPIRB has been activated. GNSS tests within the app can show a map view pinpointing where the test was performed and additional data.

4. Operation
4.1. Activation
The GLOBALFIX™ V5 EPIRB is designed for manual activation (Category 2). In an emergency, follow the clear instructions on the device to manually activate it. Once activated, the EPIRB will transmit a 406 MHz distress message, including GPS coordinates, to a worldwide satellite network. It will also send an AIS alert locally, and the RLS will confirm that your distress message has been received.
4.2. How it Works
The EPIRB utilizes a multi-constellation GNSS receiver, combining Galileo GNSS and GPS satellite networks for faster location acquisition and improved accuracy. This ensures that your beacon can be located within 100 meters, 95% of the time, within 3 minutes of the distress signal.

5. Maintenance
5.1. Battery Life
The GLOBALFIX™ V5 EPIRB is equipped with a 10-year battery. It provides 48 hours of operational life once activated. Regularly check the battery status using the mobile app via NFC to ensure it is within operational parameters.
5.2. Inspection
Periodically inspect the EPIRB for any signs of damage, corrosion, or wear. Ensure the antenna is intact and the manual release bracket (if applicable) is functioning correctly. Keep the device clean and free from obstructions.

6. Troubleshooting
For most diagnostic checks and minor issues, refer to the ACR product mobile app. The app provides detailed information on battery status, self-test results, and GNSS performance. If the app indicates a fault or if you encounter any operational issues not covered by the app's diagnostics, contact ACR customer support.
- False Activation: In the event of a false activation in the USA, immediately call the toll-free number 855-406-USCG (8724) to report it and prevent unnecessary search and rescue operations.
- App Connectivity Issues: Ensure NFC is enabled on your smartphone and that the phone is placed correctly against the EPIRB for connection.
