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.

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

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.

Y1-03-0250 Rev. B 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:

NOAA SARSAT Beacon Registration
NSOF, E/SP3
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.

Y1-03-0250 Rev. B 4

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.

Y1-03-0250 Rev. B 5

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 Cospas-Sarsat system has saved over 23,500 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 or download coordinates from an
external 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).

2. Anatomy of your beacon

NOTE: When unpacking your beacon, it is recommended that you save the

original packaging for re-use when shipping the beacon for battery
replacement in the future.

// Activation switch with Witness Tab

The activation switch embodies a special, patented method of activating a
beacon. Refer to a subsequent section of this manual for how to activate the
beacon.

// Optional External GPS interface

3. 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.

Category II beacons are designed to be manually deployed from the
bracket.

Two conditions must be met for a Category II beacon to automatically
activate:

// It must be out of its bracket
// It must be wet

NOTE:

Category I and II beacons can always be manually activated in or out of
their bracket.

The beacon and bracket are designed to allow the user to perform periodic
testing while the beacon is in its bracket.

Either condition by itself will not automatically activate the beacon.

Y1-03-0250 Rev. B 10

Category I beacons-Automatic deployment and activation

HRU releases the rod
separating the front and
back cover of bracket at a
depth between 4-13 feet.

Ejector Spring launches EPIRB
from the bracket allowing it to
float freely to the water surface.

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.

NOTE: Transmission of the 121.5 MHz and 406 MHz signals will not occur
until 100 seconds after activation.

Y1-03-0250 Rev. B 11

Category I and II Beacons-Manual deployment and activation

Push the main switch up
90 degrees, slide toward
antenna and all the way
down to activate.

Witness tab will break

once placed in the “ON”

position.

Both Category I and II beacons can be manually deployed by removing the
beacon from the bracket.

Once removed, the beacon can be activated by placing it in water OR by
lifting the Activation Switch to a vertical position, sliding it toward the
antenna and pushing down to the opposite side of the beacon. Activating
the beacon in this manner breaks off the Activation Witness Tab and allows
the switch to properly seat, showing the “ ▌ “ symbol (ON).

A Category I or II beacon MANUALLY activates with the following sequence:

1.) Remove the beacon from its bracket

2.) Activation method one: Place beacon in water

3.) Activation method two:
// Lift the switch to a vertical position
// Slide the switch toward the antenna
// Push the switch down to the opposite side of the beacon (see

illustration below)

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.”

Y1-03-0250 Rev. B 12

TIPS FOR OPTIMUM DEPLOYMENT OF AN ACTIVATED BEACON:
When activating and deploying your beacon in an emergency, DO

NOT:

// Hold or clutch the beacon or antenna
// Operate the beacon while hand held, if at all possible
// Turn the beacon off for any reason, including to save power
// Activate the beacon if you have any other means of self rescue
// Operate the beacon inside a life raft or under any other canopy or

cover

// Tether the beacon to the bracket or vessel

When activating and deploying your beacon in an emergency, DO:

// Follow the steps to activate the beacon as described on the beacon or

in this manual
// Give clear view to the sky for best performance
// Take the EPIRB with you if abandoning ship, provided there is time to

get it
// Tether beacon, using the lanyard, to the life raft and let the beacon

float (if in a life raft)
// Keep EPIRB upright for best signal transmission, either by floating it,

resting it or holding it in this position
// Manually activate the beacon if it has not been automatically activated

4. Turning off the beacon

If your beacon was manually activated and you wish to deactivate, return
the thumb switch to the “OFF” position. If automatically activated and you
wish to deactivate, remove the beacon from the water and dry the unit or
place the beacon back into the release bracket. 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.

To prevent false alarms, it is important to be aware of how your beacon can
be activated. An ACR 406 MHz EPIRB can be activated by two different
methods. Whether you have a Category I or Category II, these methods are
the same.

When the beacon is out of its bracket and wet, the unit will start

//

transmitting
When the switch is moved to the “ON” position, in or out of the

//

bracket, the unit will start transmitting

Precautions to prevent false alarms

Do not mount or transport the beacon within 4.6 ft/1.4 m of a

//

magnetic source.
Do not store the beacon outside of its bracket if it can get wet.

//

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.

This unit will need to be replaced in

August 2012. Scratch off “AUG 8” and
“2012” on the HRU date calendar

1. Marking battery and Hydrostatic Release Unit expiration dates

: It is the beacon owner’s responsibility to record the expiration dates

NOTE

for both the beacon battery and the HydroFix™ hydrostatic release unit.
This information must appear on the product itself.

The left side of the battery housing indicates the battery expiry date. Space
is provided for the beacon owner to mark the date the beacon was placed
into service. The beacon should be serviced 5 years from the installation
date but no later than the battery expiry date.

from the date

, whichever comes

2. Mounting location

The selection of a mounting location will vary from vessel to vessel.
Beacons should be protected from outside influences while being readily
accessible at all times in the event of an emergency.

The location selected must be sufficiently rigid to support the weight of the
total installation.

Hazards to avoid when selecting a mounting location:

// Vibration
// Exposure to the elements
// Possibility of impact from hatches, gear, or personnel
// Harmful vapors
// Exhaust
// Harsh chemicals
// Locations that can be obscured by foreign articles on a temporary or

permanent basis.

Y1-03-0250 Rev. B 15

CAUTION: Keep this beacon a safe distance away from all
magnetic sources. Magnet safe distance is 4.6 ft or 1.4 m, including
the distance from stereo speakers.

CAUTION: Category I brackets must be mounted free from
obstruction to allow the beacon to automatically float free from the vessel
in case of sinking. The SeaShelter3™ can be mounted on a vertical
surface with the beacon antenna pointing skyward or a horizontal surface
with the beacon face up. Avoid mounting locations that subject the
bracket to breaking waves. Avoid structures like dodgers or cabin tops
that could trap the beacon upon deployment.

CAUTION: Category II brackets must be mounted in a protected
location that is easily accessible should it be necessary to abandon ship.

The QuickDraw™ can be mounted on a vertical surface with the beacon

antenna pointing skyward or a horizontal surface with the beacon face
up. Avoid mounting locations that subject the bracket to breaking waves.
Avoid mounting locations that do not provide protection from harmful UV
rays of the sun. The bracket must be mounted facing inboard to avoid
being lost overboard due to impacts of breaking waves, personnel or
loose gear.

Visually inspect the area surrounding the mounting bracket installation site
for hidden hazards or obstacles that may have been overlooked during the
location selection. If there is any doubt as to the ready accessibility to the
beacon at all times or if any condition may appear to be questionable,
conduct a complete and thorough investigation before final approval of the
installation.

: When selecting the beacon bracket location, be sure to consider the

NOTE

requirement for four screw holes to secure the bracket.

Y1-03-0250 Rev. B 16

3. Category I bracket

The SeaShelter3™ Category I bracket has five pre-drilled screw holes to use
for securing the bracket to a flat surface. Remove the SeaShelter

™ lid by

3

turning the spring loaded knob on the lid 1/4 turn counterclockwise and pull.
The lid will lift away from the top of the base and disengage at the bottom of
the base. The lid is tethered to the base to help prevent loss. Pull the
beacon with steady pressure from the bracket. It is not necessary to remove
the HydroFix™ Hydrostatic Release Unit (HRU) to mount the bracket using
four of the holes. For extreme conditions a fifth hole is available when the
HydroFix is removed and the ejector spring is deployed. The bracket can be
held in place to mark the placement of the screw holes or you can use the
mounting template provided. The use of #10 pan head stainless steel
fasteners (minimum of ½” long) and ½” washers (not included) is
recommended. Make sure that fasteners will not contact any wires or
plumbing before drilling pilot holes.

Y1-03-0250 Rev. B 17

4. Category II bracket

Push to Release

Top in First

Bottom in Second

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. This location must be easily accessible in order to manually
deploy the beacon or to perform the required maintenance and functionality
tests. Typical locations include near the helm station or just inside the
companionway door.

The QuickDraw™ Category II bracket has three pre-drilled screw holes to
use for securing the bracket to a flat surface. Remove the beacon from the

bracket. To do this while holding the assembly, press the “PUSH” lever to

release the beacon from the bracket. Pull the beacon forward and down to
remove. The bracket can be held in place to mark the holes. The use of #8
pan head stainless steel fasteners and washers (not included) is
recommended. Be sure to confirm that fasteners will not contact any wires
or plumbing before drilling pilot holes.

To reinstall the beacon inside the bracket, place
the antenna behind the top notch in the bracket.
The yellow lanyard roll faces the bracket and rests
in the concave part of the bracket. Snap the
beacon into place by pushing firmly at the bottom
of the beacon (on the ACR logo) until the snaps
engage the bottom of the beacon.

Y1-03-0250 Rev. B 18

5. Installing the Optional optical GPS interface cable

The beacon is fitted with an
optical interface to connect with
an external Global Positioning
System (GPS) receiver that will
determine the latitude and
longitude of its position.

The black lead wire with white
stripes should be connected to
the output of the external GPS
receiver positive transmitter pin.
The black wire should be
connected to the negative pin.

If you have a Category I beacon and bracket, the connector is at the end of
the black lead wire plugs into the beacon via the bezel on the top of the

beacon. See the location of the GPS interface in previous figures (“Anatomy
of your beacon”, page 7 and “Top View”, page 8). It is important to seat the

connector completely in the bezel for an operational connection.
If you have a Category II beacon and bracket, your connector has two

extensions on it that must be aligned with the two notches on the Category II
beacon bezel. The connector is then gently inserted downward into place
and turned 90° to lock the connector into the bezel.

If the external GPS receiver is operational and the connection has been
correctly made to the optical interface, the green LED in the optical interface
will start flashing at activation.

NOTE:

4800 bps. If you are not sure if your receiver is NMEA 0183 compliant,
check the interface settings listed in your GPS manual. To optimize your
GPS interface feature, be sure that your GPS receiver is equipped with a
NMEA 0183 Version 1.5 or higher with GPGGA sentence enabled.

Consult your GPS receiver manual for the maximum cable length
acceptable for an external GPS connection to the beacon. Also see
Appendix A for information regarding the use and testing of your GPS
system in conjunction with the beacon.

Using the optical interface is not necessary for the beacon to function
properly; it will, however, enhance the beacon’s performance.

The baud rate output for your GPS receiver NMEA 0183 should be

Y1-03-0250 Rev. B 19

STEP FOUR - MAINTAINING THE BEACON

1. Safety DOs and DON’Ts

On a routine basis aboard ship, DO NOT:

// Hold or carry the beacon by its antenna
// Mount the beacon in its bracket close to large structures or magnetic

areas

// Tie the lanyard to the EPIRB bracket or any other structure
// Obscure the beacon by placing objects in front of it

On a routine basis aboard ship, DO:

// Mount the beacon in its bracket in an obvious location, so that all can

see it

// Mount the beacon in its bracket with the rolled lanyard facing inward

(facing the bracket)

// Follow the recommended maintenance schedule
// Perform a beacon Self-Test monthly
// Follow up with beacon service if Self-Test fails

2. Routine beacon maintenance

At least every ninety days, the float free mounting bracket and beacon
should be inspected for deterioration and/or residue buildup that may affect
the function of the beacon or automatic release. Part of the visual check
includes checking the antenna for tightness. Clean the beacon and the
mounting bracket to remove any residue buildups. It is recommended that
the beacon and mounting bracket be wiped with a damp cloth.

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.

3. 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. During each
inspection, check the time remaining until battery replacement is required.
The battery must also be replaced if the beacon has been activated for any
use other than the Self-Test.

Y1-03-0250 Rev. B 20

Always refer battery replacement and any other beacon service to a factory
authorized Service Center. Find a Center near you at

http://www.acrelectronics.com/brc.htm. Battery replacement includes

servicing the beacon by replacing all o-rings, testing the water seal and the
electrical properties and doing a full functional test on the unit.

NOTE:

the beacon except to disable (in case of faulty or accidental activation).
Otherwise, always have the beacon serviced.

To avoid possible fire, explosion, leakage or burn hazard, do not open,
recharge, disassemble or heat beacon above +70º C (+158º F) or
incinerate.

These products contain lithium in the battery. Various beacons may or may
not require special shipping instructions due to the lithium batteries and
changes in shipping regulations. Shipping of hazardous materials requires
special handling and documentation. MSDS sheets, along with
shipping information, can be found on our website at

http://www.acrelectronics.com/hazmat/default.htm.

In the case of the RLB-38, the product contains small batteries that are non­hazardous. However, regulations can change. Be advised that it is best to
verify the shipping requirements at the time you are preparing to ship the
unit.

There are no user serviceable items inside the beacon. Do not open

WARNING: Battery contains lithium

4. Shore based maintenance for SOLAS vessels, (SBM) IMO
MSC/Circ. 1039

The Maritime Safety Committee has approved guidelines for shore-based
maintenance of satellite beacons, for the purpose of establishing
standardized procedures and minimum levels of service for the testing and
maintenance of satellite beacons. 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.acrelectronics.com for organizations that perform shore
based maintenance.

5. Annual testing for SOLAS vessels, IMO MSC/Circ. 1040

SOLAS regulation IV/15.9 dictates annual testing of 406 MHz satellite
EPIRBs. Testing should be carried out using suitable test equipment
capable of performing the relevant measurements. All checks of electrical
parameters should be performed in the self-test mode, if possible. These
tests can be performed by certified ACR Battery Replacement Centers
(BRCs). Visit ACR’s website at www.acrelectronics.com for authorized ACR
BRCs.

Y1-03-0250 Rev. B 21

6. Changing ownership or contact information

As the owner of the beacon, it is your responsibility to advise the national
authority of any change in the information on the registration form. If you are
transferring the beacon to a new owner, you are required to inform the
national authority. You can do this by using their online database or by
letter, fax or telephone and informing the authority of the name and address
of the new owner.

The new owner of the beacon is required to provide the national authority
with all of the information requested on the registration form. This obligation
transfers to all subsequent owners. Registration forms for the United States
are available from NOAA by calling [phone] (212-SAVE) or by
visiting the ACR website at www.acrelectronics.com. Outside of the United
States, the new owner may contact his local authority for the necessary
form(s).

7. Lost or stolen EPIRBs
If your EPIRB is lost or stolen, do the following immediately:

// Report to your local authorities that the EPIRB has been lost or stolen
// Contact NOAA at [phone] (212-SAVE), or your national

authority, with the following information:

o Police department name
o Police department phone number
o Police case number

If your EPIRB were to be activated, the information you provided will be
forwarded to the appropriate search and rescue authorities who will ensure
that your EPIRB gets back to you. If someone attempts to register an EPIRB
reported as stolen, NOAA or your national authority will notify the
appropriate police department. Visit www.cospas-sarsat.org for more
information.

8. Servicing the SeaShelter3™ and the HydroFix™ HRU

The SeaShelter3™ Category I bracket has two main
pieces, the lid and the base. To open the bracket, turn the
spring loaded knob counterclockwise 1/4 of a turn and
pull. The lid will lift away from the top of the base and
disengage from the detent at the bottom of the base. The
lid is tethered to the base to help prevent loss.

Brackets are a key part of the overall beacon system.
They hold a beacon ready for deployment while preventing
false alarms. Category I brackets also require replacement
of the Hydrostatic Release Unit every two years.

Y1-03-0250 Rev. B 22

NOTE:

Whenever a beacon is returned for service, it

must be accompanied by the bracket.

To remove the expired HRU

When opening the SeaShelter

™ lid, note that the beacon is installed with

Reinstall the beacon with lanyard face in. Beacon should fit snugly in the
bracket with the antenna captured by the bracket. Reinstall the lid by seating
the bottom of the lid to the detent on the base. Close the upper portion of
the lid so the HRU rod lines up with the spring loaded knob. With gentle
pressure, hold the lid while you turn the lock counterclockwise until it stops,
then clockwise until it stops. This should capture the HRU and snap the lid
into a locked position. Confirm that the lid is attached to the bottom of the
bracket and the HRU.

Summary

Green LED

Do not force the lid closed. If the lid does not close easily,

check to see that the beacon is properly installed in the bracket and the
HydroFix™ is properly seated.

9. Servicing the QuickDraw™

To remove a beacon from the Category II bracket, press the “PUSH” lever to
release the beacon from the bracket. The beacon will now be able to
forward and down out of the bracket.

It is not anticipated that the QuickDraw™ will require servicing other than
cleaning or, rarely, replacement.

NOTE: Whenever a beacon is returned for service, it must be accompanied
by the bracket.

10. Self-Testing the beacon

The Satellite3 406™ 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. Do not exceed sixty (60) Self-Test cycles limit in the five-year life
of the battery, to conserve the battery for emergency use.

The functional Self-Test is initiated by momentarily
lifting the Activation Switch to a vertical position and
holding it in this position for at least one second and at
most four seconds. A beep indicates the initiation of
the Self-Test sequence. Self-Test will check battery
capacity and perform four functional test sequences as
described below.

TEST SUCCESS FAIL

The last green LED indicates a successful test. If any of the individual tests
fail during Self-Test, there will be two beeps and a red LED flash at the end
of the Self-Test. Self-Test will discontinue at that point.

NOTE:

The “beeps” are a very high-pitched tone that some people may not

be able to hear. You may count the green LED flashes.

APPENDIX A - USING AND TESTING THE GPS SYSTEMS

1. How the external GPS interface works

The beacon is fitted with an optical interface to connect with an external
Global Positioning System (GPS) receiver that will determine the latitude
and longitude of its position. This data is transmitted to the emergency
system. When the beacon is coupled to a working external GPS receiver, it
immediately begins downloading data. Once valid position data has been
obtained, the beacon will attempt to update the positional data every 20
minutes. The Satellite3 406™ will store the last valid positional data for up to
4 hours, if it becomes unable to obtain new updated data. It will update this
data if and only if it receives new good positional data from the external
GPS receiver.

2. Using the external GPS interface

Once a compatible, operating GPS receiver is connected to the Satellite3
406™, the beacon will store coordinate data for incorporation into the
emergency message. The coordinates are transmitted to the satellite when
the beacon is activated in an emergency. Coordinate data provides a more
accurate location to the Search and Rescue Authority and may lead to a
faster rescue. Since the last valid GPS position data may stay in the
memory for up to 4 hours, the user should take care to make sure that the
GPS position data stored is accurate. This can be accomplished by two
methods:

// By always leaving a properly functioning external GPS receiver
connected to the beacon before activation, or…
// By connecting a properly functioning external GPS receiver with a
valid position fix, and allowing sufficient time to acquire valid GPS position
data.

3. Testing the external GPS interface

Connect the optical interface plug to the beacon bezel and allow sufficient
time for the GPS receiver to acquire valid GPS position data (usually less
than 1 minute; but it can take up to 20 minutes). Lift the thumb switch to the
vertical (Self-Test) position and release. Your beacon will confirm that it has
acquired valid GPS data by flashing an extra green LED at the end of a Self­Test.

4. Updating the external GPS position data

When the beacon is properly connected to a functioning and compatible
GPS receiver, GPS position data is automatically updated about every 20
minutes while valid GPS position data is present. The operator can force the
acquisition of new GPS position data by initiating a Self-Test with the
beacon connected to an external GPS receiver with a valid position fix. This

Y1-03-0250 Rev. B 25

bypasses the normal, programmed, waiting time of 20 minutes for the
automatic update of GPS position data.

If no valid GPS position data is available, the beacon will keep the
previously stored GPS position data for up to 4 hours. In this case, call ACR
Customer Service at [phone] for instructions on how to reset the
beacon with the default message.

A new beacon is programmed with the GPS position data set to a default. If
the beacon should be activated, this default GPS position data indicates to
the satellite system that the beacon has no valid GPS position stored in
memory. Once a functioning and compatible external GPS receiver is
properly connected to the beacon, the default data will be replaced by valid
GPS position data, as described in the previous sections.

5. LED indication of GPS fix

When the beacon is activated and valid coordinates are acquired, the data
is included in the digital message of the next 406 MHz transmission. The
LED blinks green when GPS coordinates are sent.

If a time period of 4 hours passes without the internal GPS receiver being
able to update the last good set of navigational coordinates, the message
transmitted by the beacon will revert back to default data. At this point the
green LED will stop blinking and the red LED will flash. The internal GPS will
continue to seek coordinates and when successful the green LED will flash.
This new data will be transmitted in the next message burst and the green
LED will continue to flash.

6. Compatible GPS receivers

External GPS interface requirements: In order to be compatible with the
Satellite3 406™, an external GPS receiver must provide location information
according to the following requirements:

// NMEA 0183, Version 1.5 or higher
// Baud rate: 4800
// Talker device identifier: GP (GPS Receiver)
// Sentence format: GGA (GPS Fix Data)

APPENDIX B - THE COSPAS-SARSAT SYSTEM

1. 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.

Cospas-Sarsat satellites receive distress signals
from EPIRBs transmitting on the frequency of
406 MHz. The Cospas-Sarsat 406 MHz beacon
signal consists of a transmission of non­modulated carriers followed by a digital message
format that provides identification data. The 406
MHz system uses satellite-borne equipment to
measure and store the Doppler-shifted frequency
along with the beacon’s digital data message and
time of measurement. This information is
transmitted in real time to an earth station called
the Local User Terminal (LUT), which may be
within the view of the satellite, as well as being stored for later transmission to other
LUTs.

The LUT processes the Doppler-shifted signal from the LEOSAR and determines the
location of the beacon, then the LUT relays the position of the distress to a Mission
Control Center (MCC) where the distress alert and location information is immediately
forwarded to an appropriate Rescue Coordination Center (RCC). The RCC dispatches
Search and Rescue (SAR) forces.

The addition of the GEOSAR satellite system greatly improves the reaction time for a
SAR event. This satellite system has no Doppler capabilities at 406 MHz, but will relay the
distress alert to any of the LUT stations. When there is GPS data included in the distress
message, SAR authorities instantly know your location to within 110 yards (100 m). This
speeds up the reaction time by not having to wait for one of the LEOSAR satellite to pass
overhead. Because most of the search and rescue forces presently are not equipped to
home in on the 406 MHz Satellite beacons signal, homing must be accomplished at 121.5
MHz.

Once the 406 MHz signal is relayed through the LEOSAR and/or GEOSAR network, SAR
forces determine who is closest, and then proceed to the beacon using the 121.5 MHz
homing frequency.

2. Global Positioning System (GPS)

The GPS system is a satellite group that enables a GPS receiver to
determine its exact position to within 30 m (100 ft.) anywhere on
earth. With a minimum of 24 GPS satellites orbiting the earth at an
altitude of approximately 11,000 miles they provide users with
accurate information on position, velocity, and time anywhere in the

world and in all weather conditions. The GlobalFix™ iPRO stores

adds this data to its distress transmission, allowing search and
rescue forces to narrow the search to a very small area, thus
minimizing the resources required, and dramatically increasing
the effectiveness of the overall operation.
