STEP ONE - REGISTERING YOUR BEACON Why is registration important? As the owner of this 406 MHz beacon, it is mandatory that you register it with the EPIRB national authority of your country: It is the law. Please note that all 406 MHz beacons are required to have their registration updated every two years by the owner.

2. Faxing a registration is also acceptable. Fax the registration form to the fax number on the top of the registration form. NOTE: Do not confuse the registration form with the ACR Electronics warranty card. 3. If online or fax registration is not available, mail the registration form with...

Registration outside of the United States In countries other than the United States, 406 MHz beacons are registered with that country’s national authority at the time of purchase. The sales agent should have assisted you in filling out the forms and sending them to the country’s national authority.
STEP TWO - HOW THE BEACON WORKS How your beacon brings help 406 MHz beacons are a type of portable emergency equipment that transmits a distress signal to search and rescue (SAR) organizations. The purpose of these beacons is to aid SAR teams in tracking and locating ships or individuals in jeopardy as rapidly as possible.

Activating your beacon WARNING: This transmitter is authorized for use only during situations of grave and imminent danger. Deliberate misuse may incur a severe penalty. Overview Category I beacons are designed to be automatically deployed and activated in the event of a sinking vessel. The beacon may also be hand held on the deck of vessels, or floated in water and attached to a raft or life vest with the lanyard provided.
Page 12
Category I beacons-Automatic deployment and activation If the vessel sinks, the HydroFix™ HRU frees the beacon from the bracket, allowing it to float to the surface. Built-in sensors detect that the beacon is no longer in its bracket and when continuity is created by water between two of the top cap screws, an activation circuit is completed.
Page 13
Category I and II Beacons-Manual Activation Without Deployment The beacon can be manually activated while still in its bracket by placing the Activation Switch in the ON position. Activation by this method overrides all sensors and turns the beacon “ON.” Witness tab will break once Push the main switch up placed in the “ON”...

The beacon normally takes up to 12 seconds to deactivate. If deactivation should fail, remove the four screws holding the unit together and unplug the battery to disable the unit. Return the beacon to ACR Electronics for service. False alarms To prevent false alarms, it is important to be aware of how your beacon can be activated.
Page 15
Precautions to prevent false alarms Do not mount or transport the beacon within 4.6ft/1.4m of a magnetic source. Do not store the beacon outside of its bracket. Do not mount the EPIRB backwards in its bracket (lanyard roll must face in). Do not clean the beacon with a water hose and brush while out of its bracket.
The beacon should be serviced 5 years from the installation date but no later than the battery expiry date. The ACR HydroFix™ HRU has an expiration date of 2 years from the date of installation or 4 years from the date manufactured, whichever comes first.

CAUTION: Keep this beacon a safe distance away from all magnetic sources. Magnet safe distance is 4.6ft or 1.4m, including the distance from stereo speakers. Category I bracket ™ Category I bracket has five pre-drilled screw holes to use The SeaShelter ™...
Page 19
Category II bracket Category II brackets are designed to hold the beacon securely in place. The beacon must be manually deployed. The bracket can be mounted on a vertical flat surface with beacon antenna up or on a horizontal flat surface facing skyward.
Carefully inspect the beacon case for any visible cracks. Cracks may admit moisture, which could falsely activate the beacon or otherwise cause a malfunction. Any cracks observed should immediately be referred to ACR Service for evaluation. Call ACR Electronics Technical Service +1 (954) 981- 3333. Battery replacement Battery replacement is due 5 years from date after the beacon placed into service, or by expiry date on the beacon whichever is first.

The first shore based maintenance on all ACR EPIRBs is due at the date of the first battery replacement. Visit ACR’s website at www.acrartex.com for organizations that perform shore based maintenance.

Registration forms for the United States are available from NOAA by calling (888) 212-7283 (212-SAVE) or by visiting the ACR website at www.acrartex.com. Outside of the United States, the new owner may contact his local authority for the necessary form(s).

WARNING: Discard the expired HRU. Failure to replace the entire assembly may cause the bracket to malfunction. WARNING: Be sure to use only ACR’s HydroFix™ HRU (ACR P/N 9490) ™. Use of unauthorized replacement parts will void your in the SeaShelter warranty and may cause the bracket to malfunction.

The RLB-37 beacon may be self-tested as is warranted, up to a maximum of sixty times in the five-year life of the battery, or once per month for the life of the battery. Self-Tests can be performed randomly. However, ACR recommends that you perform the Self-Test on a once per month schedule.
Page 25
Extended GPS test The beacon may be tested for GPS functionality, however, this may only be done once in the five-year lifetime of the battery due to the significant drain on the battery. This test is not necessary at any time in the life of the beacon, but is made available in the event that the beacon owner wishes to verify internal GPS engine viability.
APPENDIX A - USING AND TESTING THE GPS SYSTEMS Internal GPS position system The GlobalFix™ PRO is fitted with an internal GPS receiver that will determine the coordinates (latitude and longitude) of the beacon’s position on the globe, to be transmitted to the Cospas-Sarsat emergency system. When the beacon is turned on, the internal GPS is immediately turned on and it attempts to acquire positional coordinates.
APPENDIX B - THE COSPAS-SARSAT SYSTEM General overview EPIRBs transmit to the satellite portion of the Cospas-Sarsat system. Cospas-Sarast satellites are an international system that utilizes Russian Federation and United States’ low altitude, near-polar orbiting satellites (LEOSAR). These satellites assist in detecting and locating activated 406 MHz satellite beacons.
1 (one) year* from date of purchase or receipt as a gift. During the warranty period ACR Electronics, Inc. will repair or, at its option, replace the unit at no cost to you for labor, materials and return transportation from ACR.
