NOTE re: Applicable products

This manual supports all configurations of GlobalFix™ PRO/ RLB-37
beacons. In addition to the part numbers listed on the cover page, other
configurations of these products are available, thus you may have
purchased a product configuration with a somewhat different part number.
As long as the first four digits are the same as one of the two part numbers
on the cover, this manual is applicable.

STEP ONE - REGISTERING YOUR BEACON

Your unique ID code
programmed inside each EPIRB is
transmitted to Search and Rescue
(SAR). SAR forces use this code to pull
up your registration to find out valuable
information about who needs help.

YOUR RESCUE WILL
BE DELAYED IF YOUR
BEACON ISN’T PROPERLY
REGISTERED!

1. 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.

note that all 406 MHz beacons are required to have their registration updated
every two years by the owner.

Please

HOW REGISTRATION WORKS:
All 406 MHz beacons transmit a Unique Identifier Number (UIN) when

activated. This UIN is programmed into the beacon based on the country in
which the beacon is registered, thus authorities are able to determine which
country’s database will have your registration information. SAR forces will
have information as to who you are as the owner of the beacon, the name
and type of vessel that you have, your homeport, and who to contact that
might know of your current situation - but only if your beacon has been
properly registered. Valuable search and rescue resources are wasted every
year responding to false alarms, and registering your beacon helps to resolve
false alarms quickly.

Y1-03-0242 Rev. F 3

2. What country should I register in?

Register your beacon with the EPIRB national authority of the country for
which the beacon was programmed, typically the country where purchased,
regardless of where you do your boating.

The beacon must be reprogrammed if you, as the owner, move or the vessel
sails under the flag of a different country than the one for which the beacon
was previously programmed. To verify the country for which a beacon is
programmed, see the label with the UIN (Unique Identification Number) on
the back of the unit. Units that do not have a country specified on the UIN
label are programmed for the United States.

3. How do I register?

Registration in the United States
The national authority that accepts registrations in the United States is the
National Oceanic and Atmospheric Administration (NOAA).

Here are three ways to register:

1. The fastest and easiest way to register is online at

www.beaconregistration.noaa.gov/.

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

the pre-addressed, postage paid envelope to:

SARSAT Beacon Registration NOAA
NSOF, E/SPO53
4231 Suitland Road
Suitland, MD 20746

All registration forms will be entered in the 406 MHz beacon registration
database within 48 hours of receipt. The information you provide on the
registration form is used for rescue purposes only.

A confirmation letter, a copy of the actual registration and a proof-of­registration decal will be mailed to you within two weeks. When you receive
these documents, please check the information carefully with the
existing label on the unit, and then affix the decal to your beacon in the

area marked “BEACON DECAL HERE.” If you do not receive confirmation

back from NOAA in the expected timeframe, call toll free [phone] for
assistance.

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. Alternatively, many countries allow online
registration in the International 406 MHz Beacon Registration Database
(IBRD) at www.406registration.com.

To verify that the unit is properly programmed for your country, view the UIN
label on the back of the unit. In the event that the beacon is not programmed
for your country, the sales agent (if properly equipped) can reprogram the unit
for the correct country.

4. Do I need a radio license?

In the United States, you may or may not need to obtain or update a radio
station license. Check the FCC’s website at

http://wireless.fcc.gov/services/index.htm?job=licensing&id=ship_stations or

call toll-free [phone] (CALLFCC) for the latest information.
Outside of the United States, contact your local authority for the

requirements.

STEP TWO - HOW THE BEACON WORKS

1. 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.

The 406 MHz frequency is a worldwide dedicated emergency frequency that
is detected by a special system of satellites called the Cospas-Sarsat system.
This satellite system was established by, and continues to be supported by,
its primary benefactors - the USA, Russia, Canada and France. The Cospas­Sarsat system has saved over 24,800 lives - and counting - since its
inception. See Appendix G or the Cospas-Sarsat website for more
information about the system at www.cospas-sarsat.org.

When a 406 MHz beacon is activated, the digital distress message is sent to
Cospas-Sarsat satellites and, in turn, the distress message is relayed to SAR.
The distress message contains important information about the beacon and
its owner. Additional information about the beacon is accessed by SAR from
the beacon registration database. At the same time the 406 MHz signal is
activated, a 121.5 MHz signal is turned on. The 121.5 MHz signal is used by
SAR to home in on the beacon as they approach it.

The 406 MHz signal is detected by multiple satellites and from that
information the location of the beacon can be calculated. This data alone is
sufficient for SAR to find persons or ships in distress in a reasonable
timeframe. However, as a further enhancement, some beacons have a GPS
engine onboard. This feature allows the beacon to acquire current location
coordinates from an internal GPS receiver. The coordinates are added to the
ID of the unit, which is transmitted with the 406 signal. This enables the SAR
authorities to locate the beacon to an accuracy of 110 yards (100 m).
