PLB3 USER MANUAL
1. ABOUT YOUR PLB3
1.1 Cospas-Sarsat System
The basic Cospas-Sarsat concept is illustrated in the
adjacent figure. The System is composed of:
• distress radio beacons (ELTs for aviation use, EPIRBs
for maritime use, and PLBs for personal use) which
transmit signals during distress situations
• instruments on board satellites in geostationary and
low-altitude Earth orbits which detect the signals
transmitted by distress radio beacons
• ground receiving stations, referred to as Local User Terminals (LUTs), which receive and
process the satellite downlink signal to generate distress alerts
• Mission Control Centers (MCCs) which receive alerts produced by LUTs and forward them to
Rescue Coordination Centers (RCCs), Search and Rescue Points Of Contacts (SPOCs) or other
MCCs
The Cospas-Sarsat System includes two types of satellites:
• satellites in low-altitude Earth orbit (LEO) which form the LEOSAR System
• satellites in geostationary Earth orbit (GEO) which form the GEOSAR System
The new MEOSAR system, which is not yet fully operational (2022), already brings significant advan-
tages to many users in terms of better satellite coverage, faster alerts and improved detectability and
is also the basis for the Return Link Service (RLS) on Galileo satellites.
1.2 Return Link Service
The Galileo Return Link Service (RLS) is a free-of-charge global service available to Cospas-Sarsat
RLS compatible beacons. The RLS feature is an indication on the PLB3 that confirms to the User that
the distress signal from the PLB3 has been localised by the Cospas-Sarsat system and is being sent
to the SAR authorities. It does NOT mean that a search and rescue mission has been launched, but
only confirms that the distress alert has been received by the Cospas-Sarsat system and is being
routed to the appropriate SAR agencies. The RLS aims to send an acknowledgment to the beacon
within 30 minutes following activation (the response may not be received by the beacon for signif-
icantly longer). RLS is an optional function and may not be permitted in all countries. The full RLS
specification can be found here:
https://gsc-europa.eu/sites/default/files/sites/all/files/Galileo-SAR-SDD.pdf
1.3 AIS System
AIS systems operate on VHF radio bands and transceivers are fitted to all commercial shipping and an
ever growing number of recreational vessels globally. Shortly after activation an AIS Location device
will activate an alarm on all AIS equipped vessels within the
VHF range alerting them to the fact that a person is in the
water needing assistance. Often it is a vessel in the close
vicinity of an incident that is able to react and effect a rescue
quicker than the emergency services.
Emergency service craft are fitted with AIS receivers allowing
them to pinpoint a casualty in the water more precisely than
any other system.

PLB3 USER MANUAL

1.4 Introduction
The rescueME range of products provides the user with the latest technology specifically designed
for compact size and ease of operation. Primarily designed for use when permanently attached
to a Personal Floatation Device, in the event that you fall overboard, the PLB3 is intended to alert
your vessel and plot your location on a suitable AIS equipped chart plotter on other vessels within
VHF radio range. At the same time the PLB3 will alert the 406MHz Cospas-Sarsat satellite global
emergency system. Equipped with the latest RLS technology, in the event of activation, the PLB3 will
indicate that the emergency signal has been received via the satellite system and passed to land
based Mission Control Centres to initiate appropriate rescue services. When used on land the AIS is
restricted use in conjunction with the 406MHz distress transmission.
The Galileo Return Link Service allows people in distress to receive automatic
acknowledgement that their signal has been received.
1.5 Exposure to RF Energy
This product has been evaluated for compliance with the FCC RF exposure limits given in CFR 47 part
1.307(b) at a distance of greater than 5cm and complies with EN62479 (EU) and RSS-102 (Canada).
1.6 Warnings
!Take great care to keep well clear of eyes and face as the antenna will be released very
quickly. Keep at least 30cm (12”) clear to avoid possible injury.
!Contains Lithium batteries:
- store between -30°C (-22ºF) to+70°C (+158ºF)
- DO NOT ATTEMPT TO REPLACE THE BATTERIES YOURSELF
unauthorised opening and battery replacement may put
your life at risk.
- do not short circuit, incinerate or recharge.
!The battery in your PLB3 should be replaced immediately if it has been activated, or if
the test indicator shows the battery as “used”, or if the expiry date marked on the unit
has been exceeded.
!Battery replacement must be carried out at an Ocean Signal authorised battery replace-
ment centre using manufacturer supplied battery components.
!THE PLB3 WILL NOT FLOAT without the floatation jacket and should be attached securely
to the life jacket when fitted. The PLB3 is not designed to be operated floating in water.
Hold clear of water when activated.
!This equipment is intended for emergency use only and it should not be used for routine
tracking of persons or property, including routine tracking of divers.
!Operate the PLB3 in open space rather than operating inside a life raft or under any
similar cover or canopy.
!If self-test is performed more frequently than once a month, then battery life may be
reduced.
!It is a legal requirement to register your PLB3 with your National Authority.

1.9 NFC and Mobile App.
The PLB3 is capable of connection to devices using Near Field Communication (NFC). NFC technology
allows communication between two electronic devices over a distance of 4cm (1.5”) or less. The
benefit of using NFC in the PLB3 is that the power used for communication comes from the mobile
device and not the beacon.
The Ocean Signal mobile App. allows a user to access the PLB3 and see the programmed details and
the latest test results giving a clear indication of the beacon’s condition.
Download the App. here: Android iOS
To use the App. simply touch your mobile device to the front of the PLB3 where you see “NFC”.

2.5 AIS message reception
The method in which an AIS message is displayed will depend on the reception equipment being
used. AIS enabled plotters will display a target either as a ship or SART target with the PLB3’s
preprogrammed MMSI number that identifies it as an AIS Location device.
2.6 Rewinding the antenna
!If the PLB3 is activated during this process, turn it off by
pressing the TEST/OFF Key until the red LED flashes twice.
!Rotating the antenna rewind tool in the clockwise direction
will damage the antenna
• Use the Antenna Rewind tool supplied in the box.
• Place the moulded cap of the antenna into the space
• Pass the tool through the round hole in the top of the PLB3
and place over the antenna just behind the cap.
• Rotate the tool anti-clockwise until the antenna is fully
wound.
• Hold the tool keeping the antenna coiled
Do not remove the tool until the slider is in place
• Push the Activation Slider into place
• Release and remove the rewind tool to allow the antenna to
rest behind the Activation Slider
NOTE: Refer to section 5 when installing in a life jacket regarding attachment of the Acti-
vation Tape to the Slider.
2.7 False Alerts
If the PLB3 is accidentally activated, it should be immediately turned off. If the unit was active for
more than 30 seconds the nearest Coast Guard Centre or Rescue Coordination Centre should be
contacted to explain that the PLB3 has been activated in error and there are no follow up rescue
actions required. See inside the back cover for information required in the event of a false activation.
If appropriate make a call on the VHF radio to announce the same information.
The information that should be reported includes:
• the PLB3 15-Hex ID;
• date, time, duration and cause of activation; and
• location at time of deactivation.
Note: In the event of a false activation in the USA call toll free: 1-800 851 3051
3. TESTING
Routine testing of your PLB3 once a month is recommended to ensure it is in good working order.
Follow the notes below on the frequency that tests are carried out. Remember that each test will
reduce the battery capacity slightly and reduce the operation time of your PLB3 during an emergency.
Should a test fail it is advised to repeat the test to confirm failure before returning the PLB3 to Ocean
Signal or an approved service agent.
!When carrying out any test the antenna should be extended.
If the PLB3 activates during the removal of the antenna retainer, press and hold the
Test/Off button until the LED flashes red twice to deactivate.

please only carry out this test in the first 5 minutes of each hour.
!The battery must be replaced either prior to the expiry date shown on the rear label or
after the PLB3 has been activated.
!If, during a self test, the LED flashes magenta or amber the PLB3 may not have
sufficient energy to operate for the specified 24-hour period. Battery replacement is
recommended.
NOTE: The flash sequence will be repeated after a short pause and then the PLB3 will
automatically power off.
NOTE: A single AIS transmission will occur during a Functional Test indicating “MOB
TEST” on AIS receivers within range.

PLB3 USER MANUAL
14 912S-03718 v01.00 14/11/2022
3.2 GNSS Test
!This test should only be performed where the PLB3 has a clear and unobstructed view
of the sky. This is required to allow the GNSS receiver to acquire a signal from sufficient
satellites to allow it to determine a position. Ensure the area marked “GNSS Antenna” is
not obstructed.
It is recommended that a GNSS test is carried out at least once every six months to ensure correct
operation of the PLB3.
Press and hold the TEST key. The LED will illuminate red to indicate the key has been pressed,
then start flashing. Shortly after, the LED will cease flashing and become a steady red light.
Release the TEST Key now.
During the GNSS test the LED will repeat a short green flash until either a position fix is obtained
or the GNSS test fails.
A successful test will be indicated by long red followed by a number of green LED flashes and
an unsuccessful test will be indicated by a number of red LED flashes. The number of flashes
indicates the number of GNSS tests remaining (e.g. 7 flashes = 7 tests remaining).
The test result flashes will be repeated after 2 seconds.
If there are 10 or more tests remaining then the LED will flash 10 times only (repeated).
The PLB3 has the capacity to carry out 60 GNSS tests within the lifetime of the battery.
If there are no tests remaining immediately after the current test, the LED will flash green or red
rapidly for three seconds (not repeated) depending on whether the GNSS test was successful or
not, respectively.
When there are no tests remaining, the LED will flash red rapidly for three seconds (not repeated).
The test can be ended at any time by holding the TEST key for three seconds.

5. LIFE JACKET INSTALLATION
If your rescueME PLB3 is not already installed into a life jacket, please follow the instructions below
carefully.
!The following guide is a generic guide to installation of the PLB3 to a life jacket.
Although the PLB3 is designed to fit most life jackets, always check with your Life Jacket
manufacturer to ensure there are no special fixing instructions for that model.
!When fitted to a life jacket, to prevent accidental activation, please ensure the clear
cover is fitted over the grey slider with enough free length of the activation tape so it will
not pull on the slider during normal activity of the life jacket. When carrying the PLB3
please ensure the Arming Slider is in the up position.
!For installation to life jackets where the bladder is permanently attached to the cover,
please see the separate instruction sheet, available from the Ocean Signal website.
!Once completed the installation should be tested to ensure correct activation takes
place. Refer to the life jacket manufacturer for the manual inflation process.
The PLB3 is activated when the activation slider is pulled from the front of the device by the tension
in the tape created by the inflation of a life jacket. Unless the life jacket inflates the PLB3 will not
activate.
To activate the PLB3 the activation tape must be wrapped around a substantial part of the life jacket
bladder. Many modern life jackets taper towards the neck for comfort and support in the water and
correct installation of the PLB3 must ensure that the tape is around the larger part of the bladder
rather than a tapered section where expansion may not be sufficient.
Fitting the Oral Tube bracket as low down the Oral Tube as possible usually assists in ensuring the
tape is passed around the main section of bladder.

14/11/2022 912S-03718 v01.00 17
PLB3 USER MANUAL
The diagrams above assume that the life jacket inflation tube is on the left hand side of the jacket
(as viewed from the front).
If the oral tube is on the right hand side then the PLB3 should be fitted on the other side of the tube.
5.1 Remove the Activation Slider
!The PLB3 will turn on during this process, make sure it is turned off by pressing and
holding the TEST/OFF Key until the LED flashes red twice and release.
