4. Getting Started
4.1 Registration
Before using your ResQLink View RLS, it is mandatory to register the beacon with the appropriate national authority (e.g., NOAA in the United States). Registration ensures that search and rescue personnel have access to your emergency contact information, vessel details, and medical history, which is crucial for an effective rescue operation. Failure to register may delay or prevent rescue.
- Visit the official registration website for your country (e.g., www.beaconregistration.noaa.gov for U.S. users).
- Follow the instructions to complete the registration form, providing all requested details about yourself and the beacon.
- Keep your registration information updated, especially if your contact details or travel plans change.
4.2 Battery Information
The ResQLink View RLS comes with two Lithium Metal batteries included and installed. These batteries provide a 5-year operational life. Do not attempt to replace the batteries yourself, as this must be done by an authorized service center to maintain the unit's waterproof integrity and warranty.
4.3 Initial Setup and Attachment
Attach the beacon securely to your person or gear using the provided clips or strap. Ensure it is easily accessible in an emergency. Common attachment points include life vests, belts, or backpack straps.

5. Operating Instructions
5.1 Activating the Beacon (Emergency Use Only)
The ResQLink View RLS is for use in situations of grave and imminent danger only. False alarms can divert critical resources. To activate:
- Deploy the antenna by pulling it upwards.
- Slide the protective cover away from the activation button.
- Press and hold the red ON button for approximately 1 second until the beacon activates. The digital display will show activation status.
- Position the beacon with a clear view of the sky to optimize GPS signal acquisition and transmission.
5.2 Return Link Service (RLS)
The RLS feature provides peace of mind by confirming that your distress message has been received. Once activated, the beacon will attempt to receive a return link message from the Cospas-Sarsat system. A specific message on the digital display will indicate successful RLS confirmation.

5.3 Self-Test Function
Perform a self-test periodically to ensure your beacon is functioning correctly without sending a false distress signal. Refer to the device's specific instructions for initiating a self-test, typically involving pressing a designated test button (marked 'T') for a short duration (e.g., 2 seconds).

5.4 GPS Functionality
The integrated GPS, Galileo GNSS, and MEOSAR systems provide precise location data to search and rescue. For optimal performance, ensure the beacon has an unobstructed view of the sky when activated.

6. Maintenance
6.1 Battery Life and Replacement
The internal battery has a 5-year life. It is recommended to replace the unit or have the battery serviced by an authorized ACR dealer before the expiration date printed on the unit. Do not attempt to open the unit or replace the battery yourself.
6.2 Cleaning and Storage
Clean the beacon with a damp cloth and mild soap. Avoid harsh chemicals. Store the beacon in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the activation switch is protected to prevent accidental activation.
6.3 Periodic Testing
Regularly perform the self-test function as described in Section 5.3 to verify the beacon's readiness. Consult the full product manual for recommended testing intervals.
7. Troubleshooting
If you encounter issues with your ResQLink View RLS, consider the following:
- No GPS Signal: Ensure the beacon has a clear, unobstructed view of the sky. Move away from tall buildings, dense foliage, or deep canyons.
- RLS Not Confirmed: RLS confirmation can take some time. Ensure the beacon remains active and has a clear sky view. If confirmation is not received after an extended period, continue to maintain the beacon's clear view.
- Battery Indicator Low: If the battery indicator shows low power, the unit is nearing its end of life or has been activated for an extended period. Arrange for battery replacement or unit replacement.
- Accidental Activation: If the beacon is accidentally activated, immediately turn it off and contact your local search and rescue coordination center (e.g., Coast Guard in coastal areas) to report the false alarm. Provide your beacon's unique identification number.
