This manual is applicable to both the E5 Smartfind and the G5
Smartfind Plus EPIRBs. The Smartfind Plus contains a GPS receiver for
improved positional accuracy; some parts of this manual are applicable
only to the Smartfind Plus, and are marked accordingly.
APPLICATION
This EPIRB (Emergency Position Indicating Radio Beacon) is
designed for use in maritime emergencies, and is approved for
these contingencies.
It is not designed or recommended for use on land or in the air.
Use the EPIRB only in situations of grave and imminent danger.
Intentional false alerts may result in penalties.
REGISTRATION
This EPIRB must be registered with the appropriate national
authority.
The function of the EPIRB is to send an alert to the COSPAS-
SARSAT satellites, as described in the Appendix. How soon an
alert is received depends on the positions of the satellites at the
time, and can be influenced by overhead obstructions aboard
the vessel. Rescue time following an alert depends on the
overall performance of the Search and Rescue organisations,
which is outside the control of McMurdo Ltd.

2 MANDATORY REGISTRATION
You must register your EPIRB with the appropriate authorities.
Failure to register may slow the rescue and lead to loss of life.
In the USA failure to register may result in a fine.
In the UK you are legally required to register your EPIRB.
2.1 Overview
Every EPIRB is pre-programmed with a unique identity before it reaches the
customer. This is done by the manufacturer or, in some cases, the distributor. The
identity includes a 3 digit country code. This is the country that takes responsibility for
storing that particular EPIRB’s registration details. In most cases this is the country to
which the vessel is flagged. The country programmed into your EPIRB can be found
from its rear identity label. You must register with this country.

FLAG 232 G BRITAIN
SERIALISED 000012
CATEGORY 1 – AUTO
Class 2 –20/+55 C (-4/+131 F)
When you activate your EPIRB in an emergency, the nearest maritime search and
rescue coordination centre (MRCC) will receive the message and decode the country
code (e.g. 232). They will then access the registration database for that country and
expect to find details of your vessel, its radio equipment and who to contact. If they fail
to find this information, this may slow down any rescue.
2.2 How to register
Three registration forms are provided, two are for future use and one must be
completed immediately. These forms are pre-printed with your EPIRB’s identity; all
you have to do is complete details of your vessel and provide contact numbers.
Wherever possible the forms are also pre-printed with the correct mailing address and
a faxback number. If your form does not have a mailing address, contact your
supplier. When you have completed the form, you can choose to fax it or mail it.
It is usual to receive confirmation when you register. In the UK and USA you will also
receive a “Decal” sticker which you must fit to the EPIRB itself. The Decal is proof of
registration. Not having a Decal is an offence.

2.3 Warranty form
Please complete the warranty form supplied and fax or mail it to McMurdo Ltd. Failure
to do this may delay any future warranty claim.
2.4 Radio licence
An EPIRB is a radio transmitter and must therefore be added to your radio licence. If
you have been allocated a radio call sign, then you already have a radio licence for
your VHF or MF radio set. You should update your licence to include your EPIRB. For
further details see your licence or use these contact numbers:

2.5 Sale or transfer
EPIRBs registered in the USA, Canada, UK and Australia do not need to be re-
programmed when transferred to a new vessel. Simply complete another registration
form to inform the authorities of the transfer. Use one of the spare forms provided or
contact McMurdo Ltd for a blank form. (See warranty section at rear for address).
For most other countries, the EPIRB must be re-programmed with either the new
vessel’s Maritime Mobile Station Identity (MMSI) or its radio call sign, whichever is
required by the country controlling the new vessel.
Since the EPIRB identity contains a country code, it follows that changing the flag
state of the vessel also means the EPIRB must be re-programmed. Programming can
be carried out at McMurdo Ltd or any of our designated agents. For details of your

nearest agent, either contact McMurdo Ltd using the details in the warranty section, or
visit the McMurdo Ltd web site at www.mcmurdo.co.uk.
2.5.1 Mandatory information for Oceania
(The term Oceania is normally used to designate all the islands of the Central
and the South Pacific including Australia and New Zealand.)
Advice to owners of Emergency Position Indicating Radio Beacons:
Registration of 406 MHz satellite Emergency Position Indicating Radio Beacons
(EPIRB) with the EPIRB Registration Section of the appropriate Maritime Safety
Authority (MSA – see below) is mandatory because of the global alerting nature of the
system.
The information provided in the registration card is used only for rescue purposes.
Fill in the owner registration card immediately on completion of the sales transaction.
Mail the registration card immediately.
If the beacon is to enter service immediately, complete the registration card and fax
the information to the MSA. The original card must still be mailed to the MSA 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 MSA by letter, fax or telephone of the name and address of the
new owner.
The subsequent owner of the beacon is required to provide the MSA with the
information shown on the owner registration card. This obligation transfers to all
subsequent owners.
*The MSA is the Australian Maritime Safety Authority or the Maritime Safety Authority
of New Zealand, as appropriate, whose respective fax numbers are 06 257 2036
(Australia) and 04 382 6482 (NZ).

3 DESCRIPTION
The EPIRB is a powerful self-contained distress transmitter. It is powered by a Lithium
battery that has a replacement interval of 5 years. An EPIRB is intended to be a one-
shot device; once activated it will operate for at least 48 hours. It operates best while
floating in water, but it can also be operated while on board a vessel or in a life raft.
The key components of your EPIRB are:
Antenna This is a flexible whip. It must be near vertical when operating.
If the antenna gets bent, gently straighten it out.
Strobe light These are the bright white LEDs visible through the clear lens
dome. When the EPIRB is activated they will flash every few
seconds.
Red LED Visible through the clear lens dome at the rear of the EPIRB.
This stays on or flashes to show which mode the EPIRB is in.
Green LED Where fitted (beside the red LED), this flashes when the GPS
acquires a position fix.
Sea switch The two studs on the sides of the EPIRB are sea switch contacts.
Submerge these in water to activate the EPIRB automatically.
Keep these contacts clean – see section 10.2
Activation switch Pull the tear-off tab upwards to release the switch, then push the
switch in and move it fully left.
Test button This button enables the user to run test sequences to verify the
readiness of the EPIRB.
Lanyard Pull the lanyard spool down to free it. Use the cord to tether the
EPIRB to a survival craft.

3.1 Bulkhead bracket
If you purchased the manually activated EPIRB version, this is normally supplied with
a bulkhead mounting bracket (see section 8). The EPIRB is released by pulling out a
R-clip.
The bulkhead bracket should be sited in plain view near an emergency exit.
To avoid accidental activation if the EPIRB is removed from its mounting, the bracket
is in two sections. The removable collar section contains the deactivating magnet for
the EPIRB, so the demounted EPIRB with its attached CARRYSAFE collar cannot be
activated by moisture. This allows it to be removed easily and transported in, for
example, a wet grab bag.
WARNING
The EPIRB will NOT be activated by moisture while it is in the bracket or
in the CARRYSAFE collar (but it may activate if placed in close
proximity to a magnet). The EPIRB must be removed from all parts of
the bracket; it will then activate if immersed or if switched on manually.

3.2 Float-free enclosure
If you purchased the automatically activated version (‘a’ suffix), also known as the
“float-free” version, then your EPIRB is supplied in a plastic enclosure (see section 9).
This is much more than just a protective housing; it contains a spring-loaded lever
which automatically pushes the enclosure lid off and releases the EPIRB if your vessel
sinks. This automatic ejection is controlled by a device called a Hydrostatic Release
Unit (HRU). If the enclosure is sinking then before it reaches 4 metres (13 feet) depth
the HRU cuts a plastic rod that retains the lever; this ejects the lid and releases the
EPIRB which floats to the surface and switches on automatically, as shown below:
1. As the vessel sinks, the enclosure fills with water. The HRU contains a
blade which is released due to water pressure acting on a diaphragm.
Before it reaches a depth of 4 metres, the HRU will operate and cut the
plastic rod, releasing the coil spring.
2. The spring pushes the EPIRB and the enclosure lid outwards. As the lid
pivots off it disengages from the moulding lip that helped hold it in place.
The lid is weighted so it rolls over and falls away.
3. As the EPIRB floats away, it moves out of range of the magnet. Once
away from the magnet its sea switch becomes armed.
4. The sea switch activates. The EPIRB then floats on the water surface
with its strobe light flashing. After 50 seconds it makes its first distress
transmission.
If you need to activate your EPIRB manually, it can be freed from the enclosure after
pulling out the R-shaped retaining pin and removing the lid.
Page 10
4 CONTROLS
4.1 Activation switch
This slide switch is protected against accidental activation by a red tear-off seal which
indicates if the EPIRB has been activated previously.
The EPIRB can be activated manually by tearing the seal upwards, depressing the
locking button on the switch and sliding the switch to the left.
When the EPIRB is activated the strobe will start to flash immediately, but the EPIRB
will not make any distress transmissions for 50 seconds. This gives you a chance to
turn off if you activated it accidentally. During this time the red LED illuminates
continuously. When the red LED starts to flash, the 50 seconds delay has passed and
distress transmissions have started.
4.2 TEST button
This control allows various test sequences to be run on the EPIRB. Details of these
tests are given in Section 10.1.
4.3 Sea switch
It is important to realise that the only time the EPIRB is completely off is when it is
fitted in its mounting bracket or enclosure. As soon as you take it out, a magnetic
switch activates and puts the EPIRB into its “ready” state. It will not drain the battery in
this state, but it will turn on automatically if the sea switch contacts are immersed in
water. The sea contacts are the two studs, one on each side of the EPIRB.
Although you can control the EPIRB manually with the activation switch, the sea
switch overrides any manual settings. For the manual switch to operate properly the
EPIRB must first be dry so that the sea switch is de-activated.
To ensure the sea switch operates properly in rough seas, it has a built-in time delay.
It has to be wet for at least 2 seconds before it will activate and it has to be dry for at
least 8 seconds before it will de-activate.
4.4 LEDs
4.4.1 Strobe (white)
The strobe is the visual means of locating the EPIRB. When activated, the strobe
flashes (approximately) 21 times per minute, with a pause during the time when the
EPIRB is transmitting on 406 MHz.
Page 11
4.4.2 Red LED
The red LED is used to indicate transmissions by the EPIRB. When activated, it
flashes alternately with the strobe to indicate a good transmission on 121.5 MHz.
Every 50 seconds it illuminates for 2 seconds to indicate a good transmission on 406
MHz; immediately before the transmission the LED flashes rapidly as a warning to the
user.
When the EPIRB is first activated the red LED is illuminated continuously until the
EPIRB begins to transmit, when it begins to flash.
4.4.3 Green LED (fitted to Smartfind Plus only)
The green LED flashes alternately with the strobe to indicate that a valid position has
been obtained by the GPS receiver. Every 50 seconds it illuminates for 2 seconds to
indicate that the position is being transmitted on 406 MHz.
Every 20 minutes the GPS receiver updates its position information. If a fix is not
obtained, the green LED stops flashing, and illuminates only every 50 seconds (when
the previous position information is transmitted).
All LEDs also indicate the results of self-test – refer to section 10.1
4.4.4 Interpreting the LEDs:
There are three principal indications to the user:
• If the red LED is ON continuously, the EPIRB is active but has not yet made
a transmission. There is time to turn it off without causing an alert.
• If the red and green LEDs flash together and alternate with the strobe flash,
the EPIRB has a valid GPS position which it is transmitting regularly. This is
the normal operating condition which requires no user action.
• If the red and green LEDs flash at different rates, the EPIRB is attempting to
obtain a GPS fix. If this indication persists, it is advisable to move the EPIRB
to a different location; something may be affecting its ability to see the GPS
satellites.
The LEDs can give many other indications; these are principally for diagnostic
purposes.
4.5 Buzzer
The EPIRB contains a buzzer to give audible feedback.
When the EPIRB is activated the buzzer pulses rapidly (whilst the red LED is ON
continuously) as a warning that the EPIRB is about to transmit. Once the first
transmission is complete, the buzzer sounds synchronously with the strobe.
The buzzer is also used to indicate the results of self-test.
Page 12
5 OPERATING PROCEDURE
An EPIRB is a piece of life saving equipment. Its sole purpose is to call for help.
It must only be used in situations of grave and imminent danger.
Misuse can involve a severe penalty.
5.1 Sinking
If you have a category 1 “float-free” enclosure (see marking on enclosure label), then
if your vessel sinks, the EPIRB will automatically release itself from its enclosure
before it reaches a depth of 4 metres. The EPIRB will float to the surface and start to
operate because its sea switch
is activated.
If possible, the EPIRB should
be recovered and tied (using its
lanyard) to the survival craft. An
EPIRB is meant to mark
survivors, not the accident
scene.
For best operation leave the EPIRB floating in the sea near the survival craft, as this is
the condition for which it was designed and tested.
NOTE: Satellite coverage at the time an alert is transmitted and, if activated onboard a
ship or raft, overhead obstruction on the ship or raft, may affect whether and how soon
an alert is received by the satellite system.
5.2 Abandon ship
If the vessel is sinking and there is time to fetch the EPIRB then this should always be
done. Release the EPIRB from its mounting bracket as described in section 5.4 or 5.5
and carry it to one of the life rafts. Once the life raft is in the water, uncoil the lanyard
and tie it to the life raft, then throw the EPIRB overboard so that it floats next to the life
raft. The EPIRB will operate because its sea switch will activate.
5.3 GPS Operation (Smartfind Plus only)
The GPS receiver needs a clear view of as much sky as possible in order to acquire
signals from sufficient satellites to determine its position. Should it fail to do this, the
beacon will still transmit the 406 MHz distress signal, and its position will be
determined by the COSPAS-SARSAT satellites using Doppler techniques.
Page 13
Getting the best from your EPIRB
Your EPIRB is designed and optimised to be used floating in the sea. However, if you
have to use it in other situations, this section provides guidance on how to get the best
from your EPIRB.
Aboard ship:
DO:
• Place the EPIRB in the open,
clear of overhangs
• Keep the EPIRB upright (hold it
if necessary)
• Switch on the EPIRB
DON’T:
• Place the EPIRB close to large
structures
• Lay the EPIRB on its side
• Place the EPIRB under cover
• Secure the EPIRB lanyard to the
vessel
OK
NO NO
Page 14
In a life raft:
DO:
• Make sure you switch on the EPIRB
• Hold the EPIRB up as high as possible.
Note: the high intensity flashing strobe light may cause discomfort if viewed for
prolonged periods.
We recommend that the EPIRB is used floating in the sea
OK

Page 15
5.4 Releasing EPIRB from a bulkhead bracket
If you have an EPIRB fitted into a bulkhead bracket, pull the R-clip out of the bracket
to release the retaining strap. Hold the antenna to prevent it springing loose and lift
the EPIRB out of the mounting points.
Page 16
5.5 Releasing EPIRB from an enclosure
If your EPIRB is fitted inside a full enclosure, first remove the R-clip from the retaining
rod, then pull off the enclosure cover and remove the EPIRB.
5.6 Manual activation
If the vessel is not sinking but there is imminent danger, remove the EPIRB from its
bracket and activate it manually as shown below. Note that once activated it will flash
immediately, but it will not transmit a distress call for 50 seconds. This gives you a
chance to turn it off if you activated it in error.
Once activated the EPIRB must have its antenna as upright as possible and it must
have a clear view of the sky for proper operation. Laying it on its side or placing it next
to a metal bulkhead will impair its range and may fail to alert the rescue services.
Avoid handling the antenna, as this will also impair performance.
Page 17
5.7 Deactivation
If your EPIRB has been activated for a cumulative period in excess of 6 hours then its
battery should be replaced. This is necessary to ensure that in an emergency it will
operate for the full 48 hours required by international regulations. See section 10.4 for
battery replacement instructions.
If the EPIRB was activated by mistake or if the emergency ends then the EPIRB can
be reset back to its “ready” state as follows:
If EPIRB is still flashing then it has a fault. Refer to section 6 on False Alerts.
5.8 Re-fitting EPIRB
5.8.1 Refitting into bulkhead bracket
The EPIRB is now in its “ready” state, but its sea switch is still armed and will activate
if it gets wet. To de-activate the EPIRB fully it must be replaced in its mounting
bracket, where a magnet in the bracket will make the EPIRB safe.
Hold the bracket collar open and drop the EPIRB into the bracket. The slots in the
EPIRB fit over the locating lugs in the bracket.
Hold the collar shut and fit the R-clip to secure the EPIRB. Fold over the antenna and
locate the end moulding in the retaining slot.

5.8.2 Re-fitting into enclosure
• Referring to the illustration, place the EPIRB
on its side in the enclosure. As illustrated, the
TEST button is furthest from the back of the
enclosure.
• Engage base of EPIRB into the recess in the
lever arm.
• Push the EPIRB into the enclosure to engage
the retaining clip.
• Bend the antenna as shown and retain it in the
recess.
• Refit cover squarely, engaging the guides at
the top end and the rod through hole in cover.
• Locate cover onto back plate, then snap down
over locating lug. Check that the cover is
correctly located (see following page).
• Refit R-clip into groove at end of release rod.
(Do not fit through hole)

6 FALSE ALERTS
False alerts are a serious problem for the rescue services. About 90% of
EPIRB-initiated distress alerts turn out to be false alerts. If your EPIRB should cause a
false alert, follow the instructions below.
6.1 Stand down rescue services
It is most important that you contact the nearest search and rescue authorities and tell
them it was a false alert, so that they can stand down any rescue services. Use any
means at your disposal to make contact. Often this can be by VHF radio to the local
coastguard or mobile phone if you are within coastal range, but MF/HF DSC and
Inmarsat A, B, C, M may also be used.

6.2 Turn off the EPIRB
If the EPIRB was activated by mistake, then turn it off:
• Remove the EPIRB from any water and dry its sea switch contacts.
• Wait about 8 seconds for the sea switch to de-activate.
• If the EPIRB is still flashing then it must have been turned on manually
• Slide the activation switch fully to the right.
• The EPIRB should now stop flashing.
• Refit the EPIRB correctly into its mounting bracket or enclosure.
Modern EPIRBs have sea switches and it is not uncommon for the sea switch to
activate in rough seas or heavy rain simply because the EPIRB has been badly fitted
in its mounting bracket. The EPIRB bracket contains a magnet to hold the EPIRB in
an off state. If the EPIRB is wrongly fitted the magnet has no effect, so heavy seas
may activate the sea switch. The cure is to ensure the EPIRB is correctly fitted as
shown in section 5.8.
Page 22
6.3 Dealing with a transmitting EPIRB
In the unlikely event that your EPIRB develops a fault and will not turn off, then
prevent its radio signal from reaching the satellite using one of the following methods:
• Cut off or fold down the antenna. Wrap the EPIRB in metal foil and take
it below decks.
or
• Cut off or fold down the antenna and place the EPIRB in a metal
container or locker.
Take care when dealing with the antenna. Handle the antenna as little as
possible. Refer to Section 1 for warnings.
Leave the EPIRB in this condition for 3 days until its battery is dead, then refer to
section 10.5 for instructions on returning the EPIRB for servicing. See also section 7.
Page 23
7 FULLY DISABLING AN EPIRB
In the unlikely event that your EPIRB refuses to turn off then it may have a fault.
Procedures for dealing with a faulty EPIRB are covered in section 6 on false alerts; in
simple terms you should do the following:
• De-activate the EPIRB as described in section 6.2
• Suppress its signal by removing the antenna and wrapping the EPIRB in
metal foil, as described in section 6.3
• Leave for 3 days until the battery is used up.
WE DO NOT RECOMMEND ANY OTHER COURSE OF ACTION.
However, if it is absolutely necessary to fully disable an EPIRB (by unplugging its
battery), proceed as follows:
• Take the EPIRB below decks into a dry area.
• Locate a cross-headed screwdriver.
• Unscrew and retain the 3 sealing screws.
• Lift the lens dome off. This will lift the circuit board.
• Avoid touching the circuit board if possible
• Using fingers, unplug the three white battery connectors.
• The flashing will now cease.
• Collect all the parts and return them to your nearest service agent.
Page 24
8 BULKHEAD BRACKET INSTALLATION
8.1 Siting
The bulkhead bracket should ideally be sited in plain view near an emergency exit.
When choosing a suitable mounting position you should also consider:
• Ease of access in an emergency.
• Mount at least 1 metre (3’) from any compass equipment.
• If there is any likelihood of the EPIRB being replaced in its bracket after
activation then ensure that the antenna has as clear a view of the sky as
possible.
8.2 Mounting procedure
The bulkhead bracket is supplied with four stainless steel screws 25mm (1”) in length.
The bracket mounts against a flat surface using 4 fixing points. Offer the bracket into
the chosen position and mark through the mounting slots and drill 3mm (1/8”) holes.
Page 25
8.2.1 Mounting instruction plate
The EPIRB is supplied with a self-adhesive instruction plate, which has basic visual
instructions showing how to operate the EPIRB in an emergency.
Mount the instruction plate next to the EPIRB so that it is easily visible in an
emergency.
During vessel maintenance, ensure the plate does not get painted over or cleaned
down with strong degreasing solvents.
Page 26
9 ENCLOSURE INSTALLATION
9.1 Siting
The enclosure should be mounted upright against a vertical bulkhead. Alternately, it
may be mounted horizontally on a flat surface, such as a cabin roof. No other
orientations are recommended.
If you have a float-free EPIRB it is critical that you choose a position where the
released EPIRB will not get trapped by overhangs, rigging, antennas etc, should
the vessel ever sink. An expanse of flat surface is required to allow the enclosure lid
to eject. Use the list below to choose a suitable mounting position:
• Mount on the outside of the vessel’s structure, as high as possible.
• Mount close to the vessel’s navigation position.
• Consider ease of access in an emergency.
AVOID:
• Positions with insufficient space for lid ejection and maintenance.
• Positions within 1m (3') of any compass equipment.
• Mounting within 2m (6') of any Radar antenna.
• Direct impact from waves
• Siting where damage is likely.
• Exhaust fumes, chemical and oil sources.
9.2 Mounting procedure
The enclosure mounts against a flat surface using 4 fixing points. See illustration for
mounting dimensions, or use the backplate of the enclosure as a marking guide. To
do this, pull out the R-shaped clip and remove the enclosure lid. Note how the EPIRB
fits then remove it to somewhere dry (its sea switch is now armed).
Offer the back plate into the chosen position and mark through the mounting holes.
The enclosure is supplied with a set of 25mm (1”) stainless steel fixings. If you are
using the nuts and bolts, drill 6mm (1/4”) holes where you have marked. You will need
a 4mm Allen key to tighten the bolts. If the rear of the mounting surface is
inaccessible, use the self-tapping screws supplied. Always fit washers under heads of
the screws to avoid damaging the plastic.
Page 27
9.3 Mounting instruction plate
The EPIRB is supplied with a rigid plate giving visual instructions on how to operate
the EPIRB in an emergency. Mount this next to your EPIRB as explained in section
8.2.1.
9.4 Marking Hydrostatic Release Unit (HRU) expiry
If you are installing a float-free EPIRB you must now mark the HRU expiry date. The
HRU has a 2 year in-service life which starts as soon as it gets exposure to a marine
environment. Hence the 2 years starts at installation and it is left to the customer to
mark this date during installation. A date 2 years into the future should be marked on
the HRU body and copied onto the label on the side of the enclosure. The HRU is
marked by cutting out the corresponding dates on its label, as shown on the separate
leaflet.
The enclosure should be marked using the alpha-numeric stickers provided, then
covering them with the clear adhesive label provided (but see 9.5 first). The preferred
date format is month and year, for example: JUN 2006.
Page 28
9.5 Marking vessel name
In many countries it is usual to have your EPIRB programmed by your supplier (see
registration section). Your supplier will then mark all the EPIRB labels accordingly.
However, if your EPIRB was purchased in the USA, Canada or UK then your EPIRB
will have all the necessary markings except for vessel name. In these countries it is
usually left to the customer to mark the vessel name during installation.
It is strongly recommended (and is mandatory in some countries) that the vessel
name is marked on the rear of the EPIRB itself and also on the enclosure, if you have
one. Use the alpha-numeric stickers provided to mark the vessel name (or its
abbreviation) on the top line of the EPIRB’s rear label and again on the enclosure
label. Protect the markings with a section of the clear adhesive label provided.
1. Pick off required letter (a small
knife blade works well)
2. Apply letter to label
Repeat until name is complete
3. Cover letters with clear label
Page 29
10 MAINTENANCE
10.1 Self Test & inspection
As an important item of safety equipment, your EPIRB should be checked regularly.
The EPIRB has a built-in test capability that can be used as a confidence check. This
self-test confirms that the battery is healthy, that the GPS receiver and both distress
transmitters are functional and that the strobe light is operational. The self-test should
be performed monthly, but not more frequently. It should be performed during the first
5 minutes of the hour, to minimise disturbance on the emergency channel.
10.1.1 Standard Self Test
1. Press the TEST button until the red LED lights, then release the button.
2. The EPIRB will test its internal components and then make test
transmissions at 121.5 and 406 MHz whilst monitoring the transmitter output.
3. If all tests are successful, the buzzer will sound and the red and white strobe
LEDs will flash together a number of times.
4. If any test is unsuccessful, nothing will flash and the red LED will go out.
Operation of this test for the Smartfind Plus is identical, except that the green
LED will flash (or not) in step with the red LED.
5. The number of times the LEDs flash is an indication of the accumulated time
the battery has been in use
Accumulated Battery Use (hours) Number of flashes/beeps
0 to 4 3
5 to 6 2
More than 6 1
REGARDLESS OF THE BATTERY STATE, THE EPIRB SHOULD ALWAYS BE
ACTIVATED IN AN EMERGENCY – IT MAY STILL GENERATE AN ALERT.
If the EPIRB fails Self Test, it must be serviced.
10.1.2 Power consumption warning
If the TEST button is held down after any test has completed, a warning is given: after
20 seconds, the red LED flashes rapidly and the buzzer sounds. This indicates that
battery capacity is being reduced for no reason.
If this warning persists after the TEST button is released, the EPIRB is faulty and must
be serviced.
Page 30
10.1.3 GPS operation test (Smartfind Plus only)
To comply with COSPAS-SARSAT regulations, the Smartfind Plus EPIRB is also
capable of checking the correct operation of the GPS receiver. This test consumes
significant reserve capacity of the EPIRB battery, consequently it can only be
performed a fixed number of times. It is recommended that this test is performed only
if the performance of the GPS receiver is suspect.
This test must be performed only in a location where the beacon may be expected to
acquire a GPS position – refer to page 12 for advice.
1. Press the TEST button until the red LED lights, then release the button. Wait
while the Self Test routine runs, then immediately the strobe flashes press
the TEST button and hold it down for about 15 seconds until the red LED
lights again. (If the strobe does not flash, the Self Test failed. In such a case,
this test cannot be performed.)
2. Provided that the Self Test was successful, the Smartfind Plus will start the
“Long GPS Self Test” mode. The buzzer will sound twice, the red LED will
stay lit and the green LED will begin to flash. The TEST button may be
released at this point.
3. This test takes 15 minutes to complete. During this time, do not shield the
EPIRB and do not stand over it.
4. If the GPS receiver acquires a position, the green LED will light continuously
and the buzzer will sound 10 times. If the receiver fails to acquire a position,
the red LED will light continuously and the buzzer will sound 10 times.
5. Whether the test passes or fails, the white strobe LEDs flash to indicate how
many Long GPS Self Test routines remain available.
If the EPIRB passes Self Test but fails the Long test, it is advisable to have it serviced.
It will still generate an alert in an emergency, but it may not provide GPS-precise
position information; this may delay a rescue, as the possible search area is much
larger.
NOTE: New beacons have 10 test cycles available. When the Smartfind Plus battery
is changed, it is the responsibility of the service agent to ensure that the Long Test
cycle counter is reset, as otherwise this test may not be available.
WARNING: While the EPIRB is running this test it cannot generate a distress alert.
(Once the test is complete the EPIRB returns to normal operation without any operator
intervention.) It is therefore recommended that this test is performed only under
conditions where an emergency is unlikely to arise.
If necessary, this test may be terminated (without performing the check) by holding
down the TEST button for approximately 5 seconds until the red LED goes out.
Page 31
10.2 Mechanical inspection
During these monthly checks you should take the opportunity to inspect the EPIRB
and its mountings visually for deterioration or damage.
Note that the EPIRB is designed to allow water to circulate around the outer edge of
the dome (inside the outer clear plastic edge but outside the waterproof seal),
consequently a volume of water in this area is of no consequence.
On the EPIRB itself check the following:
• Inspect the EPIRB for any obvious damage
• Check that the lanyard is not tied to the vessel structure
• Check the battery is within its expiry date
• Check that the sea switches are clean and free from paint or grease
• Check that the antenna has not been creased, so that it erects to a near-
vertical position when released.
If during these checks it is discovered that the frangible seal has been broken, then
the EPIRB may have been activated. The battery condition is thus suspect, and the
battery should be replaced at the earliest possible opportunity. It is, however, possible
to verify the condition of the battery to a limited extent by using the indication of the
self-test, as described in section 10.1.1. If the LEDs flash more than once, then there
is a good chance that the battery will provide the specified performance. IT IS
RECOMMENDED THAT THE BATTERY IS REPLACED REGARDLESS OF SUCH
VERIFICATION.
If you have a bulkhead bracket:
• Check the EPIRB is correctly fitted and secure in its bracket
• Check that the two halves of the bracket are securely connected
If you have an enclosure:
• Check the HRU is within its expiry date
• Confirm the cover can be easily removed
• Ensure the EPIRB base is correctly fitted into the D-shaped recess and
that the antenna is correctly stowed
If the EPIRB or its mounting needs cleaning then this should be done using warm
soapy water and a damp (not wet) cloth. Do not use strong detergents or solvents.
Do not paint the EPIRB or its mounting
Do not clean with detergents or solvents
During vessel cleansing or painting remove the EPIRB and its mounting.
Page 32
10.3 HRU replacement
If you have an EPIRB in an enclosure marked Category 1 then it contains a
Hydrostatic Release Unit (HRU). This has a 2 year replacement interval. WARNING:
Failure to replace the HRU at 2-yearly intervals may result in it not actuating
correctly and releasing the EPIRB in an emergency. The expiry date, which is
marked on the HRU and on the enclosure side label should be checked regularly.
When the HRU expires you can obtain a replacement at a local marine store; ask for a
McMurdo Ltd BreaktHRU HRU Replacement Kit (Part No. 82-962-001A). The kit is
complete with breakable plastic rod, date labels and instruction sheet. The HRU
replacement procedure is as follows:
• On the enclosure, remove the R-clip and pull the cover slowly off.
• Remove the EPIRB and stow it in a dry place. It will activate if wet.
• Hold down the lever arm to take up the force of the spring.
• Push the HRU back then upwards out of the slot in the lever arm.
• When the rear clip disengages slowly release the lever arm.
• The HRU with its breakable rod can now be lifted free and replaced.
• Using pliers, remove the rear E-clip and slide off the old HRU.
• Fit the new HRU over the new rod, with its label facing outward.
• Refit the washer and the rear E-clip. Ensure rod moves freely.
• Mark the HRU with an expiry date 2 years into the future.
• Slide the HRU into the slot in the lever arm and push lever arm down.
• Engage rear washer into backplate by pushing back and sliding down.
• Look under the spring and check that the washer is fully engaged.
• Fit the EPIRB as shown in 5.8.2.
• Refit cover by engaging hole over rod and then snapping into place.
Check that the cover is correctly fitted.
• Refit R-clip through top of rod.
• On side of cover, remove old HRU expiry date and mark new date.

10.4 Battery replacement
The EPIRB uses three 9V Lithium battery packs, McMurdo Ltd type 82-939. Typically
these will have to be replaced every 5 years. The exact battery expiry date is marked
on the rear of the EPIRB lens dome; if you have a full enclosure, it is also marked on
the outside of the enclosure. The battery expiry date should be checked regularly. You
will need to replace the battery when:
• The expiry date has been reached or
• The EPIRB has been used in an emergency situation or
• A false activation exceeds 6 hours of use.
REGARDLESS OF THE BATTERY STATE, THE EPIRB SHOULD ALWAYS BE
ACTIVATED IN AN EMERGENCY – IT MAY STILL GENERATE AN ALERT.
A battery is a one shot device. It is not rechargeable or user replaceable. Battery
replacement must be carried out by a McMurdo Ltd approved service agent. The
entire set of batteries should be replaced together.
NOTE: When the battery is changed, it is the responsibility of the service agent to
reset the Long GPS Self Test counter in the Smartfind Plus. For a description of this
counter, refer to Section 10.1
Lithium batteries have special disposal requirements. Never incinerate a Lithium
battery. Never dispose of one at sea. Your service agent will deal with battery
disposal.
10.5 Servicing
All servicing must be carried out by a McMurdo Ltd approved service agent. Always
call your nearest agent and talk to their service department before returning
equipment. You can find your nearest service agent from:
• The McMurdo Ltd web site: www.mcmurdo.co.uk
• Contacting McMurdo Ltd direct (see warranty page).
• Contacting a McMurdo Ltd distributor
If the EPIRB has to be returned, the original packaging should be used if possible.
10.6 Transportation
The battery packs used in these EPIRBs are classified non-hazardous.
For shipping, the battery pack meets exemption A45 of the IATA hazardous transport
regulation for categories UN3090 (Lithium batteries), UN3091 (Lithium batteries
contained in equipment) and UN3091 (Lithium batteries packed with equipment).
For further information refer to the McMurdo Ltd website www.mcmurdo.co.uk
Page 34
10.7 GMDSS inspections
If your vessel is subject to GMDSS regulations then you can expect to get regular
visits from ship surveyors enforcing national legislation. They will check the expiry
dates and activate the EPIRB to prove that it really works and they will read the
identity message stored inside the EPIRB to check that you have registered it
properly. Leisure vessels are not subject to these inspections. However, in some
countries passenger and fishing vessels are covered by the legislation.
Page 35
11 HOW DOES IT WORK?
Your EPIRB contains two radio transmitters: one operating at 406 MHz which
transmits an alert which can be received by satellites and one operating at 121.5 MHz
which transmits a signal which can be received by overflying aircraft and Search &
Rescue (SAR) homing receivers. When you activate the EPIRB, both transmitters
start broadcasting signals. Providing the EPIRB’s batteries are in good condition, the
transmission will continue for a minimum of 48 hours.
The 406 MHz alert signal can be detected by SAR satellites. American, European and
Indian authorities operate a series of satellites in low-earth and geostationary orbits to
detect and locate aviators, mariners and land-based users in distress. The satellites,
together with a world-wide network of ground stations and Mission Control Centres
(MCC) form the International COSPAS-SARSAT Program whose mission is to relay
distress signals to the international search and rescue community.
Ground stations track these satellites and process the distress signals to obtain a
location (by using Doppler location techniques*) of the distress. The processed
information is then forwarded to an MCC where it is combined with other location and
registration information and passed to a Rescue Coordination Centre (RCC) which
alerts the appropriate SAR authorities. Successive satellite passes refine and confirm
this information. Alternatively, beacons such as Smartfind Plus can use the GPS
system to obtain a very accurate position. This position is then transmitted as part of
the distress signal.
* For an explanation, visit the webpage:
http://www.cospas-sarsat.org/DescriptionOverview/doppler.htm
The network of orbiting satellites can detect signals over the entire surface of the
earth; in addition, there are four geostationary satellites that appear fixed in position
and which detect signals over enormous areas (approximately one-third of the surface
of the earth, but excluding Polar Regions). However, the geostationary satellites,
because they are fixed with respect to the earth, cannot determine the position of the
EPIRB using Doppler.
The Smartfind Plus EPIRB contains a GPS receiver which can determine its own
position. This position is then transmitted as part of the distress signal. GPS reception
can be affected by several factors, and GPS systems do require a clear view of the
sky in order to work effectively, because the receiver needs signals from several
satellites to calculate its position. If the GPS cannot determine its position, it “fails
safe”; it does not transmit an inaccurate position, but instead sends information to
indicate that no position is available. Position information is then dependent on the
orbiting satellite system.
Once it has been activated for a distress situation, an EPIRB should not be switched
off until the SAR agency directs this.

13 APPENDIX – SATELLITE SYSTEMS
COSPAS-SARSAT satellite system
The COSPAS-SARSAT system provides distress alert and location information to
search and rescue authorities anywhere in the world for maritime, aviation and
terrestrial users in distress.
There are two satellite arrays carrying the COSPAS-SARSAT system. The principal
array is LEOSAR (Low Earth Orbit Search and Rescue) which has seven satellites in
polar and near-polar orbits. The orbits of these satellites are arranged to scan the
entire surface of the Earth; on average, a satellite comes into view every 45 minutes.
Distress transmissions from EPIRBs are picked up by the satellites and retransmitted
to ground receiving stations, which then pass the message to the appropriate rescue
organisation. On average, the total delay from activation of an EPIRB to the message
being received by the rescue services is 90 minutes.
COSPAS-SARSAT is in an advanced stage of commissioning the second satellite
array, GEOSAR (Geostationary Search and Rescue). This array uses geostationary
satellites which are always in view (over their area of coverage), so that reception of
the EPIRB signal is virtually instantaneous
GEOSAR coverage
Page 39
Global Positioning System (GPS)
The GPS system is a satellite array which enables a receiver located anywhere on
Earth to determine its position with high accuracy.
The array uses 24 satellites (plus spares) orbiting the Earth in six orbital planes, four
satellites per plane, as shown below. These are arranged so that at least five satellites
are within range of any receiver (which can be anywhere) at all times.
Each satellite transmits information which enables its position and distance from the
receiver to be calculated. By combining these data for multiple satellites, the position
of the receiver can be calculated.

16 END OF LIFE STATEMENT
At the end of the EPIRB’s useful life, it is vital that the battery be disconnected from
the main unit to prevent false alarms. False alarms cause expensive disruption to
Search and Rescue services and may endanger lives as a consequence. It is also
necessary that the EPIRB and its battery pack be disposed of in a manner that does
not present a threat of environmental damage.
Battery Removal
To disconnect the battery, turn the EPIRB over and remove the three retaining screws
using a cross headed screwdriver. Separate the clear dome from the main body of the
EPIRB. The circuit board will lift away with the clear dome; if possible avoid touching
the PCB. Using fingers; unplug the three white battery connectors and cover the
individual white battery connectors with sticky tape to prevent inadvertent short-
circuiting. Using a cross headed screwdriver remove the two retaining screws that
hold the battery assembly in place. The battery assembly can now be removed from
the main body of the EPIRB.
Disposal
The Waste Electrical and Electronic Equipment (WEEE) Directive aims to minimise
any adverse impact of electronic equipment on the environment, both during the
product lifetime and when it becomes waste. Within the European Union this
legislation is mandated by Directive 2002/96/EC, and there is similar legislation in
most other continents. The directive applies to all electronic products such as IT,
household appliances, portable electronics etc., and imposes requirements to collect,
treat, recover and recycle each product at its end of life. Electronic end-user products
must also carry a WEEE label (as below) and recovery and recycling information has
to be provided to the recycler.
This EPIRB product contains traces of lithium in the battery pack. In addition it may
contain lead and brominated flame retardants (BFRs), both in the housing material
and circuit boards.
In keeping with the directive, McMurdo Ltd strongly recommends that this EPIRB
product and its battery pack be disposed of in a sensible and considerate manner. For
example, do not simply discard the product in the domestic waste. Instead take it to a
civil recycling facility, or contact McMurdo Ltd for advice.
