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!

Y1-03-0242 Rev. D 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.

Y1-03-0242 Rev. D 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.

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 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).

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: 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.

Y1-03-0242 Rev. D 11
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.

Y1-03-0242 Rev. D 12
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.”
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 above)
NOTE: Category I and Category II beacons can be activated regardless of
whether they are removed from the bracket
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.

Y1-03-0242 Rev. D 13
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
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.
5. 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

Y1-03-0242 Rev. D 14
Precautions to prevent false alarms
// Do not mount or transport the beacon within 4.6ft/1.4m of a magnetic
source.
// Do not store the beacon outside of its bracket.
// Do not mount the EPIRB backwards in its bracket (lanyard roll must
face in).
// Do not clean the beacon with a water hose and brush while out of its
bracket.
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.

Y1-03-0242 Rev. D 15
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

Y1-03-0242 Rev. D 16
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.

Y1-03-0242 Rev. D 17
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.

Y1-03-0242 Rev. D 18
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.

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.
