STEP ONE - REGISTERING YOUR BEACON
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.
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!

Y1-03-0233 Rev. F 4
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/SP053
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-of-
registration 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.

Y1-03-0233 Rev. F 5
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.

Y1-03-0233 Rev. F 6
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.
// External GPS interface
The external GPS interface serves as the connection to the ship’s GPS
system.
// Internal GPS engine
The internal GPS engine is located where it can most readily get a clear
view of the sky.

3. Digital Display
The digital display in the beacon is used as a secondary visual aid,
supporting the green/red LED and the audio tone, which indicate the
status of the beacon during testing and during emergency operation.
The messages on the digital display typically appear as one or two words
at a time, until the entire message has been displayed.
When the beacon is activated, the display will show the message EPIRB
ON. The beacon will begin to send 406 MHz emergency signal bursts, at
which time the display provides other messages including 406 SENT,
121.5 ON and GPS coordinates, provided the data was acquired. If GPS
data has not been successfully downloaded into the beacon, the digital
display will give you tips like “GIVE CLEAR VIEW TO SKY.”
In Self-Test, the display illustrates the test result of each step with “√”
indicating a pass and “X” indicating a failure. There are a total of five
tests, plus a battery check. If all tests pass, SELF-TEST PASS will be
displayed at the end of the Self-Test mode. This will be followed by the
GPS coordinates horizontally scrolling through the display, provided the
beacon has successfully downloaded an external GPS location. See
Appendixes B through E for details about display messages.
Language translations of the digital display messages are available from
your local Battery Replacement Center (BRC). The messages can be
converted to French, Spanish, German and Italian. See Appendix F for a
list of messages by language.

4. 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: Either condition by itself will not automatically activate the
beacon.
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.

Y1-03-0233 Rev. F 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.
NOTE: Transmission of the 121.5 MHz and 406 MHz signals will not
occur until 100 seconds after activation.

Y1-03-0233 Rev. F 13
Category I and II Beacons-Manual deployment and activation
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.”
Witness tab will break
once placed in the “ON”
position
Push the main switch up
90 degrees, slide toward
antenna and all the way
down to activate.

Y1-03-0233 Rev. F 14
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 GPS 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
5. 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.
6. False alarms
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

Y1-03-0233 Rev. F 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 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.
Reporting
Should there be, for any reason, an inadvertent activation or false alarm,
it must be reported to the nearest search and rescue authorities. The
information that should be reported includes:
// The EPIRB 15-digit Unique Identifier Number (UIN)
// Time and date
// Duration and cause of activation
// Location of beacon at the time of activation
To report false alarms in the United States, contact any of the
following:
US Region
Telephone Number
Atlantic Ocean / Gulf of Mexico
USCG Atlantic Area Command
Center
[phone]
Pacific Ocean Area /
USCG Area Command Center
[phone]
USCG HQ Command Center
[phone]
To report false alarms outside of the USA, contact the national
authority where your beacon is registered.

Y1-03-0233 Rev. F 16
STEP THREE - INSTALLING THE BEACON
1. Marking battery and Hydrostatic Release Unit expiration dates
NOTE: It is the beacon owner’s responsibility to record the expiration
dates 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.
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. Upon installing your beacon or new HRU, permanently
scratch the new expiration date on the HRU date calendar as seen
below.
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.
Date of Installation Example:
Date of installation of New HRU or First
Installation of EPIRB including new
HRU: August 1, 2009.
This unit will need to be replaced in
August of 2011. Scratch off “AUG 8”
and “2011” on the HRU date calendar
Date of Manufacture Example:
On the bottom of the HRU a date of
manufacture is pin stamped: 0808.
This unit will need to be replaced in
August 2012. Scratch off “AUG 8” and
“2012” on the HRU date calendar

Y1-03-0233 Rev. F 17
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 LowPro3™ 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.
NOTE: When selecting the beacon bracket location, be sure to
consider the requirement for four screw holes to secure the bracket,
plus one hole for the NMEA cable for connection between an external
GPS and the beacon, if connecting the beacon to an external GPS
receiver.

Y1-03-0233 Rev. F 18
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.
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 SeaShelter3™
lid by 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.

Y1-03-0233 Rev. F 19
4. 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. 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 LowPro3™ Category II bracket has four 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, lift the latch to release
bracket pressure from the beacon. The beacon will slide up and out of
the bracket. On either side of the bracket are release tabs.
Simultaneously depress each tab to separate the bracket from the
mounting block. The mounting block can be held in place to mark the
placement of the screw holes or you can use the mounting template
provided. 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.
