Advice to owners of Personal Satellite EPIRBs

Registration of 406 MHz satellite P-EPIRB with the Registration Section of the national authority* is mandatory

because of the global alerting nature of the system.

The information provided in the Registration Card is used only for rescue purposes and will greatly assist in any

beacon alarm incident.

Fill in the owner registration card immediately upon completion of the sales transaction. Immediately Mail the

Registration Card.

If the beacon is to enter service immediately, complete the Registration Card and fax the information to the national

authority. The original card must still be mailed to the national authority* for hard-copy reference and filing.

If the current owner is transferring the beacon to a new owner, the current owner is required to inform the national

authority* by letter, facsimile or telephone, of the name and address of the new owner.

The subsequent owner of the beacon is required to provide the national authority* with the information as shown on

the owner Registration Card.

Additional Registration Cards may be obtained by contacting ACR or the appropriate national authority.

THIS OBLIGATION TRANSFERS TO ALL SUBSEQUENT OWNERS.

*National Authority

The term “national authority” appears throughout this manual. Wherever these words appear, reference is made to

the government body responsible for registration for the country in which the unit is registered. The addresses for

various national authorities can be found on the Registration Card.

SECTION 1 - THE SYSTEM

1.1 GENERAL 1.1

1.1.1 This manual provides operation and maintenance instructions for the P-EPIRB™ 406,

Personal Satellite EPIRB, model RLB-36 hereinafter referred to as the beacon or unit.

This section describes the characteristics and details of the P-EPIRB™ 406 system.

1.2 PURPOSE 1.2

1.2.1 The beacon provides distress alerting via radio transmission on 406 MHz to satellites of

the COSPAS-SARSAT network. The unit can also transmit a distress alert to the

GEOSAR network that includes GPS latitude and longitude coordinates that are inputted

through an I/R Interface that connects to the data output of a GPS Receiver.

1.2.2 The message transmitted by the beacon is unique for each unit, which provides

identification of the transmitter through computer access of registration files maintained

by the National Authority. It is the user's responsibility to fill out and mail the

enclosed registration form to the appropriate agency of the country under which the

beacon is registered. The beacon is programmed by ACR during manufacture and can be

reprogrammed by an ACR authorized programming facility for the registered country.

Remember, if your beacon is not registered, SAR Authorities do not know who you

are, where you live or where to contact anyone who might know anything about your

situation.

1.2.3 Once Search and Rescue (SAR) forces are alerted by the units signal (406 MHz), relayed

through the COSPAS-SARSAT and/or GEOSAR network, they can converge on the

position estimated by the satellite. With GPS data in the message SAR authorities can

know your precise location and speed up reaction time. Intermediate and short range

location is aided by the unit with its on board radio beacon homing signal transmitter

(121.5 MHz).

1.2.4 Power is provided by a self-contained long life battery pack that has a recommended 5-

year replacement cycle. See Factory Authorized Service Center for replacement (Section

4.0 – Maintenance).

1.2.5 Self-test (Section 2.5) is initiated by momentarily lifting the switch to the test position

(vertical stance) then releasing back to original position. During self-test, an actual

satellite message is transmitted and certain key performance parameters are measured and

recorded. The self-test message is modified such that the satellite will not forward an alert

message during self-test. The LED will flash 3 times amber before turning green. During

this time the unit will also beep 3 times to indicate correct operational status.

Approximately 2 seconds after self-test the unit will beep and the amber LED will flash to

indicate if the unit has GPS data.

Y1-03-0155 Rev. A

1.3 SATELLITE DETECTION

1.3.1 The beacon transmits an encoded phase modulated radio signal to the SAR satellite

portion of the COSPAS-SARSAT System. The system was developed and implemented

by the COSPAS-SARSAT Partners (Russian Federation, Canada, France and the United

States).

1.3.2 COSPAS-SARSAT is an international system that uses Russian Federation and United

States low altitude, near polar orbiting satellites that assist in detecting and locating

activated 121.5/243 MHz and 406 MHz Satellite beacons. The Russian Federation

provides aboard COSMOS navigational spacecraft COSPAS payloads that are inter-

operable with the SARSAT System. In addition to weather and environmental sensors,

SARSAT payloads, provided by Canada and France, are carried aboard the United States

National Oceanic and Atmospheric Administration’s (NOAA) Advanced TIROS

environmental satellites.

1.3.3 COSPAS and SARSAT satellites receive distress signals from the beacon transmitting on

the frequency of 406 MHz. The COSPAS-SARSAT 406 MHz satellite signal consists of

a transmission of non-modulated carrier followed by a digital message format that

provides identification data for SAR authorities. The 406 MHz system uses spacecraft-

borne equipment to measure and store the Doppler-shifted frequency data along with the

satellite digital data message including GPS data, and time of measurement to identify

your position. 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. In the real-time mode, the signal

detection is limited to a mutual satellite-LUT circular visibility area of about 2500 km

radius that moves with the satellite along its track. However, because of the stored-mode

capability at 406 MHz, the need for this mutual satellite-LUT visibility is not essential,

and the system is fully functional in just the global mode.

1.3.4 The LUT processes the Doppler-shifted signal and determines the location of the distress

signal; then the LUT relays the position of the distress signal to a Mission Control Center

(MCC) where the distress alert and GPS location information is immediately forwarded

to an appropriate Rescue Coordination Center (RCC). The RCC dispatches Search and

Rescue (SAR) forces.

1.3.5 The COSPAS-SARSAT System includes 36 LEOSAR LUT Stations, 6 GEOSAR LUT

stations and 19 Mission Control Centers that provide real-time as well as global-mode

coverage for the Northern Hemisphere, while the Southern Hemisphere is presently

served primarily by the global-mode. Additional LUTs and MCCs are planned for

installation in the near future both in the northern and southern hemispheres.

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 but will relay the

distress alert to any of the LUT stations. When there is GPS data included in the distress

Y1-03-0155 Rev. A

message this will instantly tell SAR authorities where you are located. Hence speeding

up the reaction time by not having to wait for one of the LEOSAR satellite's to come

around.

1.3.6 Because most of the search and rescue forces presently are not equipped to home on the

406 MHz Satellite signal, homing must be accomplished at 121.5 MHz.

1.3.7 The P-EPIRB™ 406 is a Class 1, P-EPIRB.

Y1-03-0155 Rev. A

SECTION 2 – OPERATION

2.1 GENERAL

2.1.1 The beacon is designed to be manually deployed and activated.

2.1.2 The beacon can accept NMEA 0183 GPS Data (Version 1.5 and above, the GGA

sentence string must be enabled) through its I/R interface. Data is updated every

30 minutes once an initial position is acquired.

2.1.3 The beacon is also designed to allow the user to perform periodic testing and

confirmation of GPS connection and downloaded coordinates.

2.1.4 The beacon checks for a valid GPS data approximately every 2 seconds if no

current valid data exists.

2.1.5 The beacon will update its GPS data by initiating the self-test function if data is

present.

2.1.6 The beacon will hold the last GPS coordinates in memory until the unit is

activated. After deactivating the unit, GPS data is returned to default.

2.2 OPERATING INSTRUCTIONS

2.2.1 Activation

Unfold Antenna from around unit and move Antenna to a Vertical position (See

Figure 6) Lift Switch to the "ON" Position by lifting up and sliding over then

down to "ON" to activate the unit. "ON" position is indicated by "y" on the face of

the switch. Your beacon comes with a Breakaway tab on the switch to keep from

accidental turn-on. PUSH SWITCH down to break TAB in case of an emergency.

Once activated the unit will; Beep and the RED LED will begin to flash one red

flash approximately every 20 seconds. Unit will send Rescue message approx.

every 50 seconds and will beep after each message that has been sent. Keep

beacon with you at all times.

2.2.2 Deactivation

Turning the switch to the “Off” position will deactivate the beacon.

If the beacon continues to operate after it has been deactivated, remove the two

screws at the bottom of the unit, and unplug the battery to disable the unit.

Return it to a service center for repair.

Y1-03-0155 Rev. A

2.2.3 Self Test

The beacon self-test is initiated by lifting the switch at the top of the unit to a

Vertical Position momentarily and releasing it back to the "Off" position. Switch

is spring loaded to return to the "Off" position.

Note: "Off" Position indicated by a "O" on switch face "ON" by "y", on the face

of the switch.

Upon lifting the switch, a very short yellow flash will indicate self-test has been

initiated then the following:

Sequence of Tests

1. Check Data I/O .........................................Beep & flash yellow LED if pass

...................................................................Stop if failed

2. Check 406 MHz Synthesizer.....................Beep & flash yellow LED if passed

...................................................................Stop if failed

3. Check RF Power/Battery...........................Beep & flash yellow LED if passed

...................................................................Stop if failed

4. Unit turns on green LED to indicate Successful Test.

5. Approximately 2 seconds after the LED flashes green it will flash amber and

beep if valid external GPS data has been received.

A successful test result is indicated by: a short beep then three beeps with three

yellowish flashes concurrently then the LED turns green for pass.

NOTE: The 121.5 MHz homing beacon is inhibited during self-test.

It is strongly recommended to test the beacon on a quarterly basis.

FIGURE 6

SECTION 3 -EXTERNAL GPS I/R ADAPTER

3.1 GENERAL

Your unit comes with a GPS cable Plug Adapter that can be interfaced to your

GPS receiver to input actual GPS data into your beacon. This extra data can help

improve reaction time to your position in the event of an emergency. This data is

particularly helpful when the GEOSAR Satellite system picks up the Distress

Alert.

3.2 GPS ADAPTER

3.2.1 Connecting:

Your External GPS I/R cable attaches to your UNIT and the GPS receiver,

forming a Link for data to transfer. (Like a printer) The cable Plug’s into the

socket labeled GPS located at the top of the unit. The other end has two wires that

need to be connected to the GPS Receiver’s Data/Power Cable. Consult your GPS

Manual for wire identification.

Y1-03-0155 Rev. A

The Data/Power cable for your GPS receiver typically has connections for an

external power source and data output. Ensure proper connection.

The External GPS adapter that is supplied with your UNIT has two wires that are

polarized. The wire with the white stripe on it is the + data lead and should be

connected to the + Data lead of your GPS Data/Power connector. The other lead

with no stripe is the - Data lead and should be connected to the - Data lead of your

GPS Data/Power Cable. Use an Epoxy type Heat shrink for weatherproofing

connection.

GPS ADAPTER ILLUSTRATION

FIGURE 7

3.2.2 Setup:

The Data protocol your beacon will be accepting is the NMEA 0183 Version 1.5

and above. Set baud rate to 4800 and the GGA sentence string needs to be

enabled. Some GPS receivers have options on what strings are enabled. Ensure

the GGA string is enabled. Consult your GPS manual for further information. This

is a very common standard for GPS receivers.

Check your cable to ensure that the polarity is correct for the + data and – data

leads. It will not work if polarity is wrong.

Your GPS receiver needs to be set to this data protocol for data transfer into the

beacon. If the beacon is not showing conformation of GPS data check, protocol,

baud-rate, ensure GGA string is enabled and cable is wired correctly.

See Figure 4 for known compatible GPS receivers. Consult your GPS manual for

proper data protocol settings.

3.2.3 Testing:

Plug the Adapter into the top of the UNIT into the socket labeled GPS.

Y1-03-0155 Rev. A

Ensure your GPS has acquired a valid position. Momentarily lift the "ON/OFF"

switch to the self-test position and stand-by. The beacon will go through it’s self

test routine and approx. 2 seconds after the LED turns green the unit will beep

once and the Yellow LED will flash to indicate that valid GPS data has been

transferred into your UNIT. Repeat step 3.2.2 if no conformation.

The beacon will automatically up load new GPS position every 30 minutes if you

leave it connected to your GPS receiver.

When you activate self-test the beacon will start to look for new GPS data and

update accordingly, if no new data is present or cable is disconnected the original

data will still stay in memory.

Once data has been loaded into your UNIT it will remain there until the unit is

activated to the "ON" mode.

EXTERNAL GPS I/R CABLE

FIGURE 8

3.2.4 Default data:

Default data is when there is no GPS data in the unit. The beacon reverts to

default data once the unit has been activated and then shutoff. The unit will

function normally without GPS data.

4.0 MAINTENANCE

Y1-03-0155 Rev. A

4.1 Carefully inspect the unit’s case for any visible cracks. Cracks may admit

moisture, which could falsely activate the beacon or otherwise cause a

malfunction. Any cracking observed should be immediately referred to ACR or

nearest distributor for evaluation, (1-800-432-0227 Ext. 112) toll free in the USA.

4.2 The battery must be replaced by the date indicated on the beacon. At each

inspection, check the time remaining until replacement is required.

NOTE: There are no user serviceable items inside the unit. DO NOT OPEN THE

beacon UNLESS TO DISABLE IN CASE OF FAULTY ACTIVATION. Refer all

long life battery replacement and other internal unit service to a factory authorized

service center. For the nearest location of a factory authorized service center, call

1-800-432-0227 Ext. 112 (toll free in the USA) or +1 (954) 981-3333, Ext. 112.

It is strongly recommended to test the beacon on a quarterly basis.

5.0 REGISTRATION

5.1 It is imperative that this unit is registered with NOAA (National Oceanic

Atmospheric Administration) if used in the USA or with your own national

authority accordingly. The beacon has been programmed with a unique

identification number or code which is broadcast on 406 MHz. Registration with

the appropriate national authority provides the Search and Rescue people with

important information which will speed up the rescue operation and minimize

false alarms.

5.2 To register this unit with NOAA, simply fill out and mail the provided form in the

enclosed pre-addressed envelope to NOAA or FAX the completed form to (301)

457-5406.
