Beacon (406 MHz) Registration

Y1-03-0362 Rev. A Company Confidential 4

Registering Your Beacon

As the owner of this 406 MHz beacon, and due to the
global alerting nature of the Cospas-Sarsat satellite
system, it is a requirement that you register the
beacon with the National Authority of your country
(e.g. National Oceanic Atmospheric Administration in
the U.S., Australian Maritime Safety Authority in
Australia - online registration preferred in Australia ­and the Rescue Coordination Centre in New Zealand).
Please note that in many countries all 406 MHz
beacons are required to have their registration
updated every two years by the owner. Please check
the requirements for your country of registration.

How Registration Works

All 406 MHz beacons transmit a Unique Identifier
Number (UIN) when activated. The UIN is identified as
the 15 digit Hex ID on the beacon (see enlarged label image below for location of Hex ID on
your beacon). This Hex ID/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. Information provided during registration is used only for
rescue purposes and provides Search and Rescue forces with information as to who you are as
the owner of the beacon, the name and type of vessel that you have (if applicable), your
address, and who to contact that might know of your situation, but only if your beacon has
been properly registered.

Valuable search and rescue resources are wasted every year responding to false alerts. Please
register your beacon immediately to help resolve this issue of wasted resources.

User Tip

Beacon (406 MHz) Registration

What country should I register in? The

beacon must be registered in the country of

the owner’s residence. If the beacon is not
programmed to that country’s code and

protocol, and the residence is out of the USA,
the beacon needs to be reprogrammed.

Additionally, the beacon must be
reprogrammed if you, as the owner, move
out of the country where the beacon is
registered. To verify the country for which a
beacon is programmed, see the label with the
Unique Identification Number on the side of the
unit.

For a complete list of all countries with
registration information visit www.406registration.com

Please check to make sure that your PLB is registered correctly.

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). A NOAA registration form is included with
U.S. coded ACR PLBs (Australian coded ACR PLBs include a registration card and New Zealand coded ACR
PLBs include a registration form).

If not registering online, hard copies of 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 registration, and a registration decal (see sample image on the left in
the “User Tip” window below) will be mailed to you within two weeks by NOAA. When you receive these
documents, please check the information carefully, and then affix the decal to your beacon in the area
marked “Place Beacon Decal Here.”

It is very important that the UIN on the registration decal matches the UIN on the beacon label (see
sample beacon label on the right and sample registration decal on the left in the “User Tip” window
below). If you do not receive your registration decal back from NOAA within two weeks, call this toll free
number [phone] for assistance.

Anatomy of a Rescue

How the Beacon Works

How your beacon summons 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
network 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 tens of thousands of lives, and counting, since its
inception.

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 forces via a Rescue Coordination
Centre (RCC). The distress message contains the beacon UIN and on some models, the GPS
location of the beacon. Additional information about the beacon is accessed by SAR forces 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 forces 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 on board (all ACR PLB’s currently manufactured include a GPS engine on board)
which allows for an even more precise location of the beacon to be sent to SAR.

International customers should visit

www.406registration.com

and view the Beacon Registration Contacts List

to find the proper location to register your

beacon.

satellite system: www.cospas-sarsat.org

Y1-03-0362 Rev. A Company Confidential 8

Return Link Service (RLS)

Additionally, beacons with Return Link Service (RLS) functionality (eg. PLB-410 & PLB-435)
provide confirmation to the user that their beacon’s emergency message has been received and
that their location has been detected. RLS works by sending a signal back through the Cospas
Sarsat network to confirm to the beacon user that the distress alert from a beacon has been
received, and their location detected, by flashing a blue light (PLB-410) or flashing a blue light
and displaying a message on a digital display (PLB-435).

Important Information Regarding RLS Beacons

The PLB-410 and PLB-435 beacons have the Return Link Service (RLS) feature. The RLS feature
is an indication on the beacon (see the section of this manual on “Activating your Beacon”) that
confirms to the beacon user that the distress signal from an activated beacon has been
localized by the Cospas-Sarsat system and is being sent to the responsible search-and-rescue
(SAR) authorities. It does NOT mean that a search and rescue has yet been
organized/launched, only the fact that the distress alert has been received and is being routed
to the appropriate SAR agencies.

The RLS is designed to send an acknowledgment to the beacon. Alerting of the distress to SAR
authorities is independent of (and likely will occur before) the RLS acknowledgment indication
on the beacon. This specification is described in the Galileo SAR Service Definition Document
(https://www.gsc-europa.eu/sites/default/files/sites/all/files/Galileo-SAR-SDD.pdf).

You may visit the web page on Countries Allowing RLS Beacons (https://cospas-

sarsat.int/en/beacon-ownership/rls-enabled-beacon-purchase) to learn the most recent

information about regional/global support for RLS.

Cospas-Sarsat strongly recommends that you register your beacon. It only is possible to register
a beacon in the registry operated by the country matching the “country code” (generally
matching the country of point of sale) electronically programmed into the beacon (or the
International Beacon Registration Database (IBRD) (https://www.406registration.com/)) if the
country uses it for their registrations). For example, it only is possible to register a beacon with

a French country code in France’s national registry. However, owners of Belgian-coded beacons
must register in the IBRD. The country code is encoded in the beacon’s unique identification

number (UIN, also called Hex ID), which is used to register the beacon. Visit Where to Register
My Beacon (https://www.406registration.com/countriessupported.aspx) to see where you can

register your beacon.

Activating Your Beacon

Overview

Personal Locator Beacons are designed to be manually activated. They are only to be activated
when all other means of self-rescue have been exhausted. When properly registered as
required, the activation of the beacon tells Search and Rescue who you are, where you are, and
that you are facing a life-threatening situation. Note: Beacon should be activated in open space
with clear view of the sky (eg. Not under any sort of cover or canopy)

How to Activate Your Beacon

To activate your beacon in a distress situation, follow these steps:

1. Unclip the antenna latch from the case and rotate antenna 90

degrees into the upright position. (ON/OFF button will be exposed on
face of beacon once antenna is in upright position)

2. Depress the ON/OFF button for 2 seconds.

When activated:

The strobe light will flash twice and the red LED will
flash once to let you know the beacon has been
activated. The strobe light and Infrared (IR) strobe light
will both then continue to flash once approximately
every 10 seconds for the entire time the beacon is
activated (Note: The IR strobe is not visible to the
naked eye). The red LED will flash approximately once
every 5 seconds prior to the beacon acquiring your GPS
coordinates.

Once the beacon acquires your GPS coordinates, the
flashing red light will be replaced by a flashing green
light which will flash approximately once every 5
seconds. The flashing green light indicates the beacon
is transmitting your GPS coordinates along with your
406 MHz distress signal.

Fifty seconds after activation, a single blue light will flash
between flashes of the red or green light, indicating that the
RLS (Return Link Service) emergency message has been sent
to SAR (Search and Rescue) authorities. Once the single blue
flash changes to a double blue flash, this confirms that your
emergency RLS message has been received by SAR authorities.

Y1-03-0362 Rev. A Company Confidential 12

Activating Your Beacon (continued)

Activation with GPS

When your unit is activated, the GPS receiver will turn on,
search to find your Latitude (LAT) / Longitude (LON), and
incorporate it into your 406 MHz signal.

For the first 6 hours after beacon activation, the internal
GPS will search once every 30 minutes to find your
LAT/LON and incorporate it into your next 406 MHz signal.
If for any reason the internal GPS cannot update your
LAT/LON, your last position will be used for the next four
hours - at that time, the green LED will stop blinking and
the red LED will flash once every 5 seconds until new GPS
data is obtained. Between 6 hours and the end of
operating life (minimum of 24 hours), a GPS location
update is attempted every 60 minutes.

GPS receiver orientation

When activated, it is critical that you do not cover the beacon with any body part, water,
clothing, etc. The GPS receiver is located under the bottom portion of the case where it is
outlined with the text “GPS, Give Clear View to Sky”.

To ensure optimum performance of the GPS receiver, the beacon needs to have an
unobstructed view of the sky. PLB will not work submerged in water. Water will shield and
inhibit the GPS receiver and may cause difficulties obtaining your GPS coordinates. Avoid
leaning over the beacon to view blinking LEDs (or blinking LEDs and/or the screen on the PLB­435 model) as you may shield GPS reception.

Proper Positioning and Handling during Activation

Intended Operational Environments:

Make sure the antenna is pointing towards the sky, out of the water. PLB will not
work submerged in water. While the unit is waterproof, it must be above the water’s
surface to function properly.

Intended operational environments include on ground, above ground, and held in
hand. In all cases, the beacon must be facing skyward with the antenna
perpendicular.

Do not cover the GPS receiver with your

hand and make sure you have a clear view

of the sky to ensure GPS is acquired.

The following table describes the visual feedback on the digital display that the PLB-435
provides during activation.

Digital Display Feedback During Activation

The ACR logo appears indicating the beacon has been activated.

The system reports that it is in the process of acquiring GPS. While
acquiring GPS connection, the system reminds you that for optimum
GPS performance, position the beacon so that it has a clear view of
the sky. It will also recommend other useful operating advise such as,
“Do Not Hold Antenna”.

The system will notify you when it is about to transmit your 406 MHz
emergency distress signal. It will countdown from 3 prior to sending.

You will receive a confirmation message once a 406 MHz Emergency
Signal has been transmitted.

The system reports that the 121.5 MHz homing signal is on. Search
and Rescue (SAR) personnel use this frequency to triangulate your
location when arriving close to the scene.

The system reports recently acquired GPS coordinates.

The beacon provides confirmation when the emergency RLS message
has been sent.

The beacon provides confirmation once the emergency RLS message
has been received by SAR.

The beacon will continue to send your distress message for the life of the battery (minimum 24
hours). While valid GPS coordinates are available, the on-screen sequence will reflect the table
above when each distress message is sent. If valid GPS coordinates are not obtained after initial
activation, your distress message will continue to be sent without GPS coordinates until valid
GPS coordinates are obtained. The on-screen sequence when valid GPS coordinates are not
available will reflect the table above, except for the screen showing the GPS coordinates. The
last two screens reflected in the table above offer confirmation of RLS functionality.

Turning Your Beacon Off

Turning off the beacon

To deactivate your beacon, depress the ON/OFF button for 2 seconds. You will see 2
fast green LED flashes and all blinking LED lights will stop (and the screen will turn off
on the PLB-435 model), signifying that the beacon is no longer sending your distress
message.

NOTE: Leave beacon on until
rescued. Turning the beacon off
will prolong or prevent rescue.
Repeated activations could be
viewed as a hoax.

Hopefully you are never put in the
situation where you have to activate
your beacon to be rescued, however,
should you activate your beacon in an
emergency that requires Search and
Rescue (SAR) assistance, please
contact ACR Electronics, Inc. in the
days that follow.

It is important for us to learn the
nature of your emergency and how
the beacon performed so that we can

continue to build the world’s best

lifesaving equipment.

Real life activations and how people
use our beacons in these situations
plays a major role in designing and
manufacturing our products. We also
like to share these rescues with
others in an effort to promote proper
use of Personal Locator Beacons.

Testing Your Beacon

Your beacon has the ability to perform 2 different tests to ensure that the beacon is working
perfectly. The first is a basic self-test which checks the beacon’s design performance and sends
a self-test message transmitted with default location data. The second is a GPS/GNSS self-test
that turns the GPS receiver on, acquires your position and then transmits this data in a 406 MHz
self-test satellite burst (GPS and GNSS are used interchangeably to describe the GPS/GNSS
Test).

NOTE: Self-test should only be performed in the first 5 minutes of any hour.

Basic Self-Test (No GPS Data)

During a self-test, your beacon will send a 406 MHz signal coded as a self-test to the satellite
system and will also momentarily activate the 121.5 MHz homing signal.

The beacon has enough excess battery life to perform 60 self-tests over the 5 year life of the
battery.

To perform a basic self-test:

1. Unclip the antenna latch from the case and rotate antenna 90 degrees into the upright

position. (ON/OFF button will be exposed on face of beacon once antenna is in upright
position)

2. Depress the Test button between 2 to 5 seconds.

3. A quick flash of the blue LED is an indicator that Self-Test was initiated. This will always

be the first LED flash in the self-test sequence.

The self-test light sequence is as follows: A blue LED will flash to show the start of the Self­Test. For a successfully “passed” self-test, the blue LED flash will be followed by 3 green LED
flashes and a strobe flash. The PLB-435 will show this light sequence and will also flash a
message on the screen saying “Self-Test Pass” at the end of the self-test.

Any red LED flash observed in the above sequence indicates that the beacon has failed self-test.
Repeat the self-test. If the failure persists, contact ACR Electronics, Inc. or an authorized
Battery Replacement Center (BRC) for servicing of your beacon. The PLB-435 will flash a
message saying “Self-Test Fail” at the end of a failed self-test.

ACR strongly recommends performing the self-test once per month, or at least two weeks
prior to a trip, allowing enough time for service should your beacon require it. Do not exceed
the self-test limit to ensure confidence in the operation of the PLB for at least 24 hours.

Low Battery Indicator during Self-Test

If the total ON time of the beacon exceeds 2 hours, the beacon will flash the red
LED twice at the completion of the self-test. In addition to the LED indicators, the
display on the PLB-435 will indicate a “Self-Test Fail” and will show a low battery
warning. While the beacon may still operate normally in a distress situation, ACR
strongly recommends you have your battery replaced to ensure that you will have
at least 24 hours of battery power in an emergency.

Testing Your Beacon

GPS Self-Test (GNSS Self-Test)

The GPS receiver is located under the bottom front portion of the case (indicated by “GPS Give
Clear View to Sky”). It is imperative that the receiver is not obstructed during the GPS self-test

or during activation to ensure that the GPS receiver is acquiring your latitude (LAT) and
longitude (LON) position. This test must be performed outside with a clear view of the sky.

This beacon has enough excess battery life to perform 20 GPS self-tests over the 5 year life of
the battery. Once this GPS testing feature reaches 20 tests, the feature will be disabled by
internal software.

To perform a GPS self-test:

1. Unclip the antenna latch from the case and rotate antenna 90 degrees into the upright

position. (ON/OFF button will be exposed on face of beacon once antenna is in upright
position).

2. Depress the “Test” button between 5 and 10 seconds.

The GPS self-test light sequence is as follows: A blue LED will flash followed by 3 quick blue LED
flashes indicating that the GPS self-test has begun. Subsequent red LED flashes will occur
approximately every 5 seconds until GPS has been acquired by the beacon. Once valid GPS data
has been obtained, a long green LED flash and a strobe flash will occur, indicating a successful
GPS self-test. As long as the beacon is unable to acquire GPS coordinates, the beacon will
continue flashing the red LED for no longer than 110 seconds and then terminate GPS self-test,
indicating a failed GPS self-test. In case of a failed GPS self-test, repeat GPS self-test and if
failure persists, return the beacon to ACR Electronics, Inc. for service. The PLB-410 and PLB-435
will both display the same LED sequences but the PLB-435 will also display the following 3 things

on the screen to show a passed GPS Test: GPS Coordinates, “GNSS Test Pass,” and the total

number of GPS tests remaining that the beacon is able to run. In the event of a failed GPS Test,
the PLB-435 will display the following on the screen: “GNSS Test Fail” followed by the total
number of GPS tests remaining that the beacon is able to run.

The maximum number of GPS tests allowed is 20. If the user tries to perform another GPS test
after the maximum of 20 has been reached, there will be a green LED flash, followed by 3 quick

green LED flashes, followed by 3 red LED flashes and the beacon will then turn off (in addition to

the 3 red LED flashes, the PLB-435 will display a message on the screen indicating that the GPS
Test Limit has been reached). Additionally, if the total ON time of the beacon exceeds 2 hours,
the beacon will not allow any more GPS tests to run.

False Alarms

Preventing False Alerts

A false alert is any activation of the beacon, intentional or otherwise, that does not result from
a situation of grave and imminent danger. Be sure to do the following to help minimize false
alerts:

Register your Beacon

This does not reduce false alerts; however, when the beacon is properly registered, the
situation can usually be resolved with a phone call.

Keep Track of your Beacon

When not in your possession, be careful with whom you leave your beacon. Make sure they
know how to use it, and that they understand the ramifications of causing a false alert. A lot of
false alerts are generated by curious individuals. If you notice the beacon is flashing the red or
green LED and strobing periodically on its own, this likely means it has accidentally been
activated and needs to be shut off and reported.

NOTE: If you report a false alert and the authorities have not received the signal, do not
be concerned. This may mean that you were able to deactivate the beacon before the
signal was transmitted.

False Alert

A 406 MHz false alert MUST be reported to the search and rescue authorities.

To report a 406 MHz false alert in the United States, contact:

United States Air force Rescue Coordination Center (AFRCC)

Telephone: [phone]

To report a false alert outside of the United States, contact the national authority

where your beacon is registered. False alerts in Canada, notify the Canadian Mission Control

Center by calling 1-800-211-8107. False alerts in Australia, inform the Australian Maritime

Safety Authority, Joint Rescue Coordination Centre (JRCC Australia) and false alerts in New

Zealand, inform the Rescue Coordination Centre New Zealand (RCCNZ).

Reporting

Should there be a false alert for any reason, it must be reported to the nearest search and rescue

authorities. The information that should be reported includes:

• The PLB’s 15-digit Unique Identifier Number (UIN). Also identified as the 15-digit Hex ID

• Time and date

• Duration and cause of activation

• Location of beacon at the time of activation

Beacon Maintenance

Routine Maintenance

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
be immediately referred to ACR for evaluation by calling [phone]. ACR Technical
Support can also be reached by sending an email to: [e-mail].

After checking the beacon for cracks, it may be wiped down with a clean, damp cloth. Do not
use any type of cleaner on your beacon.

Y1-03-0362 Rev. A Company Confidential 23

Battery Replacement

Replace the battery no later than the battery expiration date specified on the beacon, or after
emergency use. At each inspection, check the time remaining until replacement is required. The
battery should be replaced if the beacon has been activated for any use other than the self­test/GPS test. Always refer battery replacements and other beacon service to a factory
authorized Battery Replacement Center.

NOTE: There are no user serviceable items inside the beacon. DO NOT OPEN THE BEACON.
Opening the beacon will void the warranty.

For the nearest location of a Battery Replacement Center, visit our website and utilize the
Dealer Locator feature located in the Support section of the site.

Beacon Transport

This beacon contains 1 lithium metal battery pack that is less than 0.8 grams. The beacon is not
classified as HAZMAT for transportation. Prior to shipping the beacon for service, alert your
carriers about the batteries contained in this equipment to make sure they properly label your

Changing ownership or contact information

As the owner of the beacon, it is your responsibility to advise the national authority of any
change in your registration information. 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.

Appendix A – Accessories

Custom ACR Skins

Custom ACR skins are available for both the PLB-410 and PLB-435 models. The PLB-435
comes with two skins (Camouflage and Aqua Marine as shown in the image below)
included when purchased. Additional skins will be available for both the PLB-410 and
PLB-435 at www.acrartex.com. Use of these exclusive ACR skins allow PLB-410 and
PLB-435 beacon owners to create a customized beacon tailored to their specific lifestyle
and preferred activities.

Application of the skins to the beacon’s face is simple. Simply remove the skin from its

liner and apply to the face of your PLB-410 or PLB-435 using the LED cutouts in the
skin as a guide for correct placement. Once the skin has been applied to the face of the
beacon, the matching antenna arm skin can be applied to the section of the antenna
arm which covers the Power (on/off) button on the face of the PLB.

Users can keep the skins on the face of their beacon and on the antenna arm Power
button cover for as long as they like. If at any time the user wishes to remove the
skins, simply peel the skins off of the PLB (the adhesive used to adhere the skins to the
PLB does not leave any residue so users can choose to not apply another skin and
simply use the beacon in the form it was when purchased, or they can choose to apply
a different skin design to the beacon). Please note that the skin applied to the face of
the PLB should be removed by peeling the skin from either the bottom right or left
corner of the skin. As can be noted, the skin for the face of the beacon is slightly
smaller than the face of the PLB and intentionally creates an area at either the bottom
right or left of the face of the PLB where the skin can be peeled off without interfering
with the main face label of the PLB (as can be seen below, there are instructions on the
skin liner indicating the corners which should be used when peeling the skin off of the
PLB).

Multifunction Accessory Clips

Indented areas on each side of the back case of the PLB shown below provide different
attachment options. Users can utilize either the Belt Clip or the Oral Inflation Clip (both
come included with the beacon) to provide different wearability options.

Y1-03-0362 Rev. A Company Confidential 30

The Belt Clip and Oral Inflation Clip are attached to the beacon as shown below. Please
note that the Oral Inflation Clip (for use when attaching the beacon to the Oral Inflation
Tube on a lifejacket) is designed to be used in conjunction with the black mounting
strap as shown. The purpose of the mounting strap is to prevent the Oral Inflation Clip
from detaching from the Oral Inflation Tube of the lifejacket. Additionally, the belt clip
can be used in conjunction with the provided velcro strap (more detail provided later in
this section).

Attachment to Lifejacket Oral Inflation Tube Using Oral Inflation Clip

After attaching the Oral Inflation Clip (with mounting strap attached to the clip) as
shown above, steps 1-4 below show how the clip is attached to the lifejacket’s Oral
Inflation Tube.

Step 1 Step 2

Step 3 Step 4

Y1-03-0362 Rev. A Company Confidential 32

Note: Step 4 above requires use of the lanyard (included with your beacon) to attach
the clip to the beacon as shown. One side of the lanyard should be threaded through
the small hole on the side of the clip and then tied to the clip using a secure knot. The
other side of the lanyard should be tied to the beacon using a secure knot (see step 4
on prior page for location where lanyard should be tied to the beacon). This offers a
failsafe to ensure the beacon is not separated from the clip. The lanyard should be
utilized in this same manner when using the Belt Clip.

Belt Clip

In addition to enabling the user to attach the PLB to a belt, the Belt Clip can also be
used in conjunction with the provided velcro strap for a variety of different usage
applications (eg. attachment to backpack straps etc.). In order to utilize the velcro
strap, thread it through the holes in the Belt Clip (as shown below) and then attach the
Belt Clip to the PLB as shown in the images at the beginning of this section. After
attaching the Belt Clip to the PLB, the lanyard should be attached to the Belt Clip in the
same fashion as shown in the image for Step 4 of attaching the Oral Inflation Clip to
the Oral Inflation Tube.
