SECTION 1 - REGISTRATION OF 406 MHz PLBS
1.1 Registration Importance
It is mandatory that the owner of this 406 MHz PLB registers it with the National Authorities*. All
406 MHz PLBs transmit a Unique Identifier Number (UIN) when activated. This UIN is programmed
in the PLB based on the country in which the PLB was purchased. Registration provides the Search
and Rescue (SAR) forces with emergency contact information, and will speed the launch of a rescue
operation. The National Authorities use the information to verify if an actual emergency exists.
Valuable Search and Rescue resources are wasted every year responding to false alarms. For PLBs
that are not registered, SAR authorities will not know who you are, or who to contact regarding
additional information of your current situation. This could delay the launch of a rescue operation.
*A National Authority is the governmental body that is responsible for PLB Registration Database
administration for the country for which the PLB is programmed.
1.2 Where to register
The owner of a 406 MHz PLB should register it with the National Authority of which the PLB was
programmed, (typically the country where purchased), regardless of where you use your PLB. Each
PLB is programmed with a UIN for the country where the unit is shipped, and will only be accepted
for registration in that country. To verify the country, for which a PLB is programmed, see the label
with the UIN on the back of the unit. Units that do not have a country specified on the UIN label are
programmed for the United States. For a list of the national authorities in your area, please view
them at http://www.cospas-sarsat.com/Management/listOfParticipants.htm
1.3 Registration in the United States
It is the Owner’s responsibility and required by law to Register 406 MHz PLBs that are programmed
for and purchased in the United States. The National Authority that accepts registrations in the United
States is the National Oceanic and Atmospheric Administration (NOAA). The owner should
complete the enclosed registration form (Do not confuse this with the ACR Electronics Warranty
Card) and mail it with the pre-addressed; postage paid envelope to:
SARSAT Beacon Registration,
E/SP3, RM 3320, FB-4
NOAA/NESDIS
5200 Auth Rd.
Suitland, MD 20746-4304
PLB registration is also available online at: www.beaconregistration.noaa.gov
The information provided on the Registration Form is used only for rescue purposes. The
Registration Form should be filled out and mailed immediately. Registration can be expedited by
faxing the registration form or by completing the form online in the event the PLB is to be placed in
immediate use.
Typically, registration forms will be entered in the 406 MHz PLB Registration Database within 48
hours of receipt. 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

Y1-03-0174 Rev. D3
information carefully and affix the decal to your PLB in the area marked “Beacon Decal here”. If you
do not receive confirmation, contact NOAA for additional information at: [phone].
1.3.1 Registration in Canada
The National Authority in Canada is the NSS (National Search & Rescue Secretariat). Canadian
residents can register online at http:beacons.nss.gc.ca. For more information please contact the NSS
at [phone] or [phone].
National Search and Rescue Secretariat
400-275 Slater Street
Ottawa, Ontario K1A 0K2
1.4 Registration Outside of the United States
In countries other than the United States, 406 MHz PLBs are registered with that country’s National
Authority at the time of Purchase. The Sales agent should assist in filling out the forms and sending
to that country’s National Authority. To verify that the unit is properly programmed for that country,
view the UIN label on the side of the unit. In the event that the PLB is not programmed for the
country in which it has been purchased, the sales agent, (if properly equipped) can reprogram the unit
for that country.
1.5 Change of ownership or contact information
It is the owner’s responsibility to advise the National Authority of any change in the information on
the registration form. If the current owner of the PLB is transferring the PLB to a new owner, the
current owner is required to inform the National Authority by Letter, Fax or telephone, of the name
and address of the new owner. The new owner of the PLB 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 are available from NOAA, call [phone] or visit
our website at www.acrelectronics.com.
1.6 Lost PLB’s
Inform NOAA immediately at 1-888-212-SAVE (7283), or your national authority, that your PLB
has been lost. They will update your PLB registration information with the appropriate information.
1.7 Stolen PLB’s
Things That You Need To Do:
• Report to your local police department that the PLB has been stolen.
• Contact NOAA at 1-888-212-SAVE (7283), or your national authority, with the following
information so your PLB registration information can be updated with the appropriate remarks:
- Police Department Name
- Police Phone Number
- Police Case Number
If your PLB was to activate, the information you provide will be forwarded to the appropriate Search
and Rescue Authorities who will ensure that your PLB gets back to you. And, if someone attempts to
register a PLB reported as stolen, NOAA or your national authority will notify the appropriate Police
Department.
Visit the COSPAS-SARSAT website for more detailed information: www.cospas-sarsat.org

Y1-03-0174 Rev. D4
SECTION 2 – RESPONSIBLE USE
2.1 The TerraFix™ 406 GPS PLB should only be used in situations of grave and imminent danger!
What exactly does this mean? Technically speaking you should only activate your PLB when all
other means of self rescue have been exhausted. This means you have tried to use your
cellular/satellite phone, signaling mirrors, strobe lights, or any other safety device you may have.
When all else fails and you feel your situation has truly become extreme, ask yourself the following
questions:
Am I in danger of losing life, limb, eye sight, or valuable property if I am not rescued soon?
Am I in danger of not surviving the night or upcoming hours if not rescued soon?
If you answer yes with confidence to these questions, it is time to activate your PLB.
SECTION 3 - FALSE ALARMS
3.1 Preventing False Alarms
•Ensure that your PLB is registered with NOAA or your national authority. This does nothing to
reduce false alarm rates, but does have a dramatic effect on the impact of a false alarm. If the PLB
is properly registered, the situation will be resolved with a phone call most of the time. It will also
help speed rescue in an actual distress.
•Test your PLB in accordance with the recommendations enclosed in this manual.
•Use care when leaving your PLB and with whom you leave it with. Ensure that they are aware of
the device and know the ramifications of causing a false alarm. A lot of false alarms are
generated by curious individuals.
•Maintain your PLB. Ensure that the batteries are within their expiration date and that all
manufacturer recommendations are followed.
•Finally, realize that the COSPAS-SARSAT satellites are very good at what they do, detecting
emergency PLBs. An activation of a 406 MHz PLB for just a few seconds will usually be
detected. After a few minutes, it will usually be detected and located. This is good if you're in
distress, but if you're not, you just generated a false alarm.
3.2 Should there be 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 PLB Unique Identifier
Number (UIN), Date, Time, duration and cause of activation, as well as location of PLB at the time
of activation. Outside the United States contact your National Authority.
3.3 To report false alarms in the United States contact any of the following:
Atlantic Ocean / Gulf of Mexico
USCG Atlantic Area Command Center Tel: [phone]
Pacific Ocean Area
USCG Atlantic Area Command Center Tel: [phone]
USCG HQ Command Center (From any location) Tel: [phone]

SECTION 4 - OPERATION
4.1 General
The TerraFix™ 406 GPS PLB models are designed to be manually deployed and activated. It is
only to be activated when all other means of self-rescue have been exhausted. Activation of the PLB
tells Search and Rescue who you are, where you are, and that you are facing a life threatening
situation.
4.2 TerraFix™ 406 GPS PLB Emergency Activation
4.2.1 Activation
To activate your PLB in an emergency situation, unfasten the antenna from the case or holster and
move it into the upright position (See figure 2). Lift the holster cover revealing the PLB keypad (see
figure 3). Depress the “self-test” and “GPS I” or “GPS I/O” buttons simultaneously for at least 1/2
second and less than 5 seconds (see figure 4). Your PLB is now activated. While transmitting your
emergency signal, the red LED will flash once every 2 seconds alerting you that your PLB is
activated. If GPS data is present in the PLB via the GPS I or GPS O the red LED will turn off and
the green LED will take over flashing once every 2 seconds.
4.2.2 Activation with GPS I (P/N 2798.2 and P/N 2798.4)
The TerraFix™ 406 GPS I and GPS I/O are equipped with a GPS Interface. Prior to activating
your PLB you can download your GPS LAT/LON into the PLB using an external GPS receiver and
the GPS Interface cable provided with the PLB. Once your external GPS has acquired good global
positioning data, press the GPS test button for at least ½ second and no longer than 5 seconds and
your GPS data will download into the PLB (for full instructions see Section 4.7.2). Once you
activate your PLB, your GPS coordinates are included in the distress signal. The green LED will
immediately start flashing every 2 seconds to alert you that your PLB is activated and transmitting
your GPS coordinates with the 406 MHz signal.

4.2.3 Activation with GPS I/O (P/N 2798.4 Only)
The TerraFix™ 406 GPS I/O is also equipped with an Onboard GPS receiver. Once activated the
TerraFix™ 406 GPS Onboard GPS engine will start up and search to find your LAT/LON and
incorporate it into your 406 MHz signal. In the case when external and internal GPS are present, the
internal GPS data will have priority at activation.
When the TerraFix™ 406 GPS I/O is turned ON, the GPS Onboard receiver is also immediately
turned ON and will immediately begin acquiring data. As soon as the GPS receiver acquires good
positioning data the red LED will stop blinking and the green LED will begin flashing once every 2
seconds. Once good global positioning data has been obtained, the GPS receiver waits for 20
minutes before looking for new positioning data again. If for any reason a time period of 4 hours
passes without the GPS receiver being able to update the last good set of GPS coordinates, the
message transmitted by the TerraFix™ 406 GPS I/O will revert to default data. At this point the
green LED will stop blinking and the red LED will flash once every 2 seconds. If at any time after
this, good GPS data is obtained, this data will be transmitted, the red LED will stop blinking and the
green LED will begin flashing again.

4.2.4 GPS Antenna Orientation (2798.4 ONLY)
When activated it is critical that you do not cover the front bottom portion of the PLB with any body
part, water, clothing, etc. The GPS Antenna is located under the front bottom portion of the case
behind the embossed ACR logo. To ensure proper operation it needs to be unobstructed with a clear
view to the sky. Avoid submerging this portion of the PLB in water if possible, as water will shield
and inhibit the GPS receiver and may cause difficulties obtaining LAT/LON coordinates.
4.3 406/121.5 Antenna Position
For maximum performance you must deploy the PLB antenna into the proper position (see figure 2).
The antenna will snap into place and be slightly slanted to the side. Be sure the antenna is positioned
facing the sky and avoid submerging in water. If afloat employ all means to keep the PLB out of the
water and the antenna dry. For best results it is important to keep the antenna dry and away from the
water. Water acts as a detractor from the performance and reduces the PLB’s effectiveness.
4.4 Deactivation
To deactivate your PLB, depress the “OFF” button for 1 second (see figure 5).
Once off, all blinking LED’s will stop signifying that the PLB is no longer sending your rescue
message.
4.5 Self Test
PLEASE READ ALL INSTRUCTIONS BEFORE PERFORMING ANY OF THE TESTS.
BE PREPARED TO RECORD DATA FROM THE TEST
Self test is initiated by holding the self test button (see figure 1) for at least ½ second and less than
five seconds. Your PLB will sound an initial beep and green LED (Light Emitting Diode) flash to
signify the test has begun. The green LED will flash a second time to indicate that the self test was
successful.
TerraFix™ 406 GPS I (P/N 2798.2) Self tested components: Data Integrity and Memory;
406 MHz Synthesizer; RF Power/Battery
TerraFix™ 406 GPS I/O (P/N 2798.4) Self tested components: Data Integrity and Memory;
406 MHz Synthesizer; RF Power/Battery; GPS header
If your PLB flashes two green LED’s, the test has been successfully completed. If you encounter
only the initial green LED flash alone, your PLB has failed the self test, please contact
ACR Electronics or an authorized Battery Replacement Center for servicing of your PLB.
NOTE: During a self test your PLB will send a 406 MHz signal coded as self-test to the satellite
system. The homing signal at 121.5 MHz is inhibited during self test; this allows you to test your
PLB any time during the day without causing any false alarms.
4.6 Battery Witness Seal Life
ACR strongly recommends performing the self test on the TerraFix™ 406 GPS on a monthly basis.
If your PLB flashes an initial Red LED at the beginning of the Self Test, this indicates that your
electronic witness has been broken and you have used more than 1 hour of battery life. While the
PLB will still operate normally in an emergency, ACR strongly recommends you have your battery
replaced and the electronic witness reset to ensure that you will have 24 hours of battery power
should you ever need to activate your unit in an emergency

Y1-03-0174 Rev. D8
4.7 GPS Testing
4.7.1 GPS O (Onboard) Test (P/N 2798.4 only)
This test is NOT necessary as 100% of all Onboard GPS receivers that leave ACR have been tested
to ensure they perform perfectly. However, if you would like to ensure your Onboard GPS is working
properly, please follow these instructions very closely.
Warning: To conserve battery power the following test should not be performed more than
once during the five-year life of the battery pack!
Note: The GPS Antenna is located under the bottom front portion of the case behind the embossed
ACR logo. It is imperative that this location not be obstructed during self test or activation to ensure
that the GPS antenna is acquiring your latitude and longitude position. This test must be performed
outside with a clear view of the sky.
The TerraFix™ 406 GPS PLB is fitted with an internal Global Positioning System (GPS) receiver
that will determine the latitude and longitude of its position. To test the internal GPS you must be
outdoors and have a clear view of the sky. The PLB must remain under observation in order to
witness the results of the test. In order to best view the results, avoid bright sunlight and noisy
locations. Depress and hold the GPS I/O button until one Red LED flash, beep and one Green LED
flash, beep are observed. (about 5 seconds apart) Then release the GPS I/O button. The live test of
the internal GPS has begun. The GPS will remain ON until LAT/LON position coordinates have
been obtained or until 10 minutes has elapsed. If valid navigation data has been obtained, the GPS
will be turned OFF and the green LED will light for at least 3 seconds. This LAT/LON data is not
saved for use when the PLB is turned ON. The green LED is proof that the GPS is functioning
properly and that the PLB is in a location or environment where it can receive the necessary signals
from satellites. If the GPS does not acquire good navigation data, the GPS will turn OFF after 10
minutes and there will be no successful green LED indication. This test should not be performed
more than once during the five-year life of the battery pack to prevent excessive battery drain.
4.7.2 Preload external GPS I (Interface)
The TerraFix™ 406 GPS PLB (P/N 2798.2 and 2798.4) can interface with a handheld GPS receiver
to provide your LAT/LON to SAR forces and narrow your search area to 110 yards (100 meters).
The PLB can accept NMEA 0183 version 1.5 and above GPS Data (format GPGGA sentence)
through its infra-red interface. The PLB can be forced to update its GPS data by pressing the GPS I
or GPS I/O button for at least 1/2 second and not longer than 5 seconds only when the beacon is off.
The TerraFix PLB will hold the last GPS coordinates in memory for 4 hours before returning to the
default. Upon activation, your GPS data will be transmitted to the GEOSAR satellite on the very first
burst. TerraFix 406 PLB will interface with most GPS receivers, if you are not sure if your receiver
is NMEA 0183 compliant please check the interface settings listed in your GPS manual.
Maximum 500 preloads during the life of the battery.
To optimize your GPS Interface feature be sure that your portable GPS receiver is equipped with the
following:
NMEA 0183 Version 1.5 or higher
GPGGA sentence is enabled

Y1-03-0174 Rev. D9
4.7.3 GPS I (Interface) connection
The TerraFix™ 406 GPS PLB (P/N 2798.2 and 2798.4) comes standard with a GPS interface cable
with serial port adapter. Connect the serial port adapter to your external GPS connection data cable.
If the holster is on the PLB, align the two tabs on the bottom of the interface with the holes in on the
holster directly above the interface port (see figure 6). Push down and turn to secure the interface
cable to the holster. If the holster in not on the PLB simply hold the interface head on top of the
interface port with your finger (see figure 7).
SECTION 5 – PLB Holster
5.1 The TerraFix™ comes standard with a protective holster that will help protect your PLB from
damage. To install the holster, deploy the external antenna and slide antenna through the open hole
located on the left side of the holster. Slide the holster to the base of the PLB so that the open
antenna hole is flush with the side of the PLB. Close the back of the holster around the back of the
PLB and clip into the front of the holster. Once secured, wrap the external antenna around the base
of the holster and clip into antenna slot on the top right side of the holster (See figure 8).
Note: Use extreme caution; do not apply the holster over the external antenna. In an emergency it is
critical that you deploy the antenna. If the holster is covering the antenna you will not be able to
deploy properly.
5.2 The TerraFix™ holster has been designed to accommodate your extreme adventures. You can secure
your PLB directly to backpack webbing straps or belts to ensure the PLB is close at hand. Ensure the
PLB is secured firmly and is protected before heading out to avoid damage or loss. ACR recommends
that you secure your PLB someplace that is easily accessible in case of an emergency for rapid
activation.
Note: Use care when attaching items to your PLB. Clipping attachments, carabineers, rope,
webbing, etc. will all add weigh and can affect the buoyancy of the PLB. Your PLB may not float if
items have been attached to it.
