1. GENERAL
1.1 Introduction
The rescueME range of products provide the user with the latest technology
specifically designed for compact size and ease of operation. The EPIRB1 is an
Emergency Position Indicating Radio Beacon (EPIRB) for manual release only. It is
intended as a carry off EPIRB, but may also be used as a supplementary alerting
device as specified in SOLAS regulations.
1.2 Exposure to RF Electromagnetic Energy
This product complies with EN62479 (EU) at separation distances of 5 mm and 25
mm and with RSS-102 (Canada).
1.3 Warnings
!It is a legal requirement to register your EPIRB with your National
Authority.
!Only use your EPIRB in a situation of grave and imminent danger.
!Deliberately misusing your EPIRB or setting it off accidentally may
result in prosecution and a fine.
!Your EPIRB contains small lithium batteries.
!Please see section 6.3 for information on safe transportation.
!The battery in your EPIRB 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.
!The EPIRB1 is supplied with a manual mounting bracket for internal
or protected areas only. See the installation guidelines in section 2 for
further information.
!Please read these instructions carefully. Failure to follow the guidance
in this manual may result in loss of warranty.
1.4 Operating Mode
Your EPIRB1 may be operated in a variety of modes.
1.4.1 Floating in water (a) ! Auto activation in water on Class 2 units only.
This is the preferred method of operation. Ensure the EPIRB is firmly tied to the
life raft or person before deployment.
1.4.2 On deck (b)
When deploying the EPIRB on a deck, ensure it is vertical and clear of obstructions
that might impede a clear view of the sky.
1.4.3 In a safety raft (c)
The EPIRB may be deployed in a life-raft, where it should be held in a vertical posi-
tion so that there is a clear view of the sky, preferably outside of the canopy.

1.5 COSPAS/SARSAT System
The COSPAS/SARSAT system utilises two satellite ar-
rays to provide distress alert and location data to
search and rescue authorities. The GEOSAR
system can provide near immediate alerting
within the coverage of the receiving satel-
lite. The LEOSAR system provides coverage
of the polar region beyond the range of the
GEOSAR system. It can calculate the location of
distress events using Doppler processing techniques and is less susceptible to ob-
structions which could block a signal in a given direction. The system is comprised
of instruments on board the satellites which detect the signals from the distress
beacons. Ground receiving stations, referred to as Local Users Terminals (LUTs)
receive and process the satellite downlink signal to generate the distress alerts.
The distress alerts, generated by the LUTs, are then received by Mission Control
Centres (MCCs) which then forward the alert to Rescue Co-ordination Centres
(RCCs), Search and Rescue Points of Contacts (SPOCs) and other MCCs.

2. INSTALLATION
The EPIRB1 should be mounted where it is easily accessible in
an emergency. The bracket should be securely fixed to a flat
bulkhead using the three screws provided. Mounting dimen-
sions are shown in the drawing. If the unit is to be mounted
externally it must be mounted in the optional manual release
housing to provide long term protection and to prevent the
EPIRB being accidentally knocked off in heavy weather.
Do not mount the EPIRB closer than 1 metre to any steering
compass as this may affect the accuracy of the compass.
Keep the EPIRB away from any strong magnetic sources such
as loudspeakers, compass compensation magnets, etc., which
might cause inadvertent activation.

4. OPERATION
!WARNING: USE ONLY IN SITUATIONS OF GRAVE AND
IMMINENT DANGER. MISUSE MAY RESULT IN A SE-
VERE PENALTY
Ensure that your EPIRB1 is always fitted with an unused battery
that is within the marked expiry date. Failure to do so may result
in reduced operating time when used in a real emergency. Please
observe the recommendations on testing in section 5.
4.1 Activation
Only activate your EPIRB in situations requiring emergency as-
sistance from the rescue authorities. Deliberate misuse of your
EPIRB may result in a fine.
• Remove the EPIRB from its bracket by pushing the tab on the
bottom of the cradle down
• To activate your EPIRB in an emergency, pull the red antenna
tab out completely until firm resistance is felt (25.5cm).
• Remove break off tab
• Lift the protective flap and press the ON key for one second
until the green starts LED flashing and then release the key.
• During operation the green LED will flash once every five
seconds while the GPS is turned on and obtaining a fix. Once
a fix is obtained, the green LED will flash quickly three times.
• Each time a 406MHz transmission is made the LED will flash
quickly five times; green for transmission with a GPS position
and red for a transmission without a position.
• The Red LED will flash every 2.5 seconds while the 121.5MHz
homing beacon is active.
• Hold your beacon with the antenna standing vertically. Keep
the area marked ‘GPS Antenna’ free from obstruction, which
would interfere with the GPS reception.

!AUTOMATIC ACTIVATION (class 2 only): When placed in water the
EPIRB1 will automatically activate in the same manner as above after a
short delay.
When operating the EPIRB in water, tether the beacon to your body or
the liferaft.
Note: The first alert is transmitted after 50 seconds to allow time to deactivate the
unit if accidentally turned on. The homing beacon is not activated until after the
first alert is sent.
4.2 Deactivation
To deactivate your EPIRB after use or if it is accidentally activated, press the ON key
for one second until the indicator LED flashes red twice, then release. Rewind the
antenna using the knob on the top of the EPIRB. Do not push the antenna back into
the EPIRB as this may cause it to be damaged.
If the EPIRB was automatically activated due to immersion in water, remove from
the water and dry thoroughly. The EPIRB will automatically switch off after ap-
proximately 30 seconds.
Should your EPIRB fail to deactivate, wind in the antenna and completely wrap the
EPIRB in several layers of aluminium foil, or place in a metal container.
4.3 False Alerts
False alerts cause the rescue authorities unnecessary time and expense.
To avoid false alerts make sure your EPIRB is safely stowed with the protective
flap closed and the antenna fully wound in. Make sure that there is no excessive
pressure applied to the protective cover. Ensure that anybody carrying the EPIRB is
fully aware that this device is for emergencies and should only be used in situations
of grave and imminent danger.
If you accidentally activate your beacon or otherwise set it off when a rescue is not
required, contact your local emergency services as soon as possible and advise
them of your beacon’s 15 digit HEX code (UIN), your current location and the time
the beacon was first activated.

5. TESTING
Routine testing of your EPIRB is recommended to ensure it is in good working
order if needed in an emergency. Monthly testing is recommended, but remember
that each test will reduce the battery capacity slightly and reduce the operating
time of your EPIRB during an emergency.
5.1 Beacon Test
!Pull the antenna out completely until firm resistance is felt (25.5cm)
before commencing the test. Retract the antenna after the test.
To test your EPIRB1 is functioning correctly, press and hold the TEST key for at
least one second. The red LED will come on to indicate the switch is depressed, fol-
lowed by the red LED flashing rapidly, indicating test mode is activated. The switch
may now be released. The strobe light will flash once (indicating that the 406 and
121.5MHz signal has been transmitted).
After a short pause, the
indicator LED will produce a
flash sequence of either:
• 1 green flash; OR
• 1 to 6 amber flashes; OR
• 2 to 5 red flashes.
!This flash sequence is
repeated a second time
after a short delay and
then the EPIRB1 will
automatically turn off.
The number of green/amber flashes in each group indicates the number of hours
the battery has been used for as shown in the table

!Because the test transmits a short burst on the aircraft distress frequency
of 121.5MHz, please only carry out this test in the first five minutes of each
hour.
!It is recommended to test your EPIRB once a month.
!The amber test result indicates the battery has been used for over one
hour or the allowed number of tests has been exceeded. The EPIRB will
still operate normally in distress, but the battery should be replaced to
ensure the full operating life when your EPIRB is needed.
5.2 GPS Test
!As testing the GPS receiver expends significant amounts of battery
energy, do not test the GPS operation more than once a year. Testing the
GPS receiver is limited to 12 tests over the lifetime of the battery, after
this the GPS test will fail to activate.
!This test must only be performed where the EPIRB has a clear and
unobstructed view of the sky. This is required to allow the GPS receiver
to acquire a signal from sufficient satellites to allow it to determine a
position. Make sure the area marked ‘GPS Antenna’ is not obstructed.
Press and hold the TEST key. The LED will illuminate red to indicate the key has
been pressed, then start flashing. After approximately ten seconds the LED will
cease flashing and become a steady red light. The TEST key can now be released.
Note: If the TEST key is released before ten seconds, the EPIRB will enter the self
test mode.
During the GPS test the LED will repeat a long red flash followed by a short green
flash until either a position fix is obtained or the GPS test fails.
A successful test will be indicated by the strobe flashing and the green LED flash-
ing. The number of green flashes indicates one more than the number of GPS tests
remaining (eg 8 flashes = 7 tests remaining). The unit automatically turns off after
the test indication.
If after five minutes the GPS receiver has not received a position, a failure will be
indicated by the red LED flashing after which the unit will turn off.
The test can be ended at any time by holding the ON key for one second or by hold-
ing the TEST key for five seconds.

6. APPENDIX
6.1 Maintenance and Troubleshooting
Your EPIRB will require little maintenance except periodic cleaning, if required.
Always use a damp cloth to clean the case and dry thoroughly. Do not use solvents
or other cleaning fluids as this may cause the plastics to deteriorate. Ensure the
antenna is free to unwind.
6.2 Batteries
The EPIRB1 contains Lithium batteries for long operating life. Your battery must
be replaced either after the expiry date or after the EPIRB has been activated, even
if only for a short period of time. Battery replacement must be done at an Ocean
Signal authorised battery replacement centre.
All Lithium batteries self discharge slowly over time at a rate that is related to tem-
perature. Maximum performance of the battery is achieved with long term storage
at an average temperature of no greater than 20°C.
6.3 Transport
When shipping your EPIRB the following guidance and regulations should be fol-
lowed, but you are advised to contact your nearest battery replacement centre or
Ocean Signal prior to shipping as regulations may have changed.
