32 INTRODUCTION2.1 COSPAS-SARSAT satellite systemThe COSPAS-SARSAT system provides distress alert and location information tosearch and rescue authorities anywhere in the world for maritime, aviation andterrestrial users in distress.There are two satellite arrays carrying the COSPAS-SARSAT system. The principalarray is LEOSAR (Low Earth Orbit Search and Rescue) which has seven satellites inpolar and near-polar orbits. The orbits of these satellites are arranged to scan theentire 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 retransmittedto ground receiving stations, which then pass the message to the appropriate rescueorganisation. On average, the total delay from activation of an EPIRB to the messagebeing received by the rescue services is 90 minutes.COSPAS-SARSAT is in an advanced stage of commissioning the second satellitearray, GEOSAR (Geostationary Search and Rescue). This array uses geostationarysatellites which are always in view (over their area of coverage), so that reception ofthe EPIRB signal is instantaneous.LEOSAR satellite path and scan footprintGEOSAR coverage
42.2 Global Positioning System (GPS)The GPS system is a satellite array which enables a receiver located anywhere onEarth to determine its exact position, usually to within 100m.The array uses 24 satellites (plus spares) orbiting the Earth in six orbital planes, foursatellites per plane, as shown below. These are arranged so that at least five satellitesare within range of any receiver (which can be anywhere) at all times.Each satellite transmits information which enables its position and distance from thereceiver to be calculated. By combining these data for multiple satellites, the exactposition of the receiver can be determined.GPS satellite orbital planesOperation of GPS receiver(size exaggerated for clarity)
53 PURPOSEAn Emergency Position Indicating Radio Beacon (EPIRB) is used to alert search andrescue services in the event of an emergency. It does this by transmitting a codedmessage on the 406MHz distress frequency. This message is relayed via satellite andearth station to the nearest rescue co-ordination centre.The satellite system is run by COSPAS-SARSAT, and has already been described.With the geostationary satellite section being commissioned, the alerting delay isreduced from typically 90 minutes to a few minutes within the geostationary satellitecoverage.Instant alerting is good news, but they still need to know where you are. Theadvantage of the Precision 406 EPIRB is that it has a built in GPS receiver, so withinminutes of activation it will have determined your latitude / longitude coordinates andwill have transmitted these to the rescue centre. The position fix is accurate to 150m*.To operate properly the Precision 406 needs a clear view of the whole sky. If its view isblocked and it is unable to get a position fix, then the system defaults to using a polarorbiting satellite to determine position. In this case, there is typically a 45 minute delaybefore the position is known and the accuracy is limited to within 5km (3 miles). This isthe original system that standard (non-GPS) EPIRBs use. To get the full advantage ofthe Precision 406 it is important to give it a clear view of the whole sky.The Precision 406 transmits a message that identifies the exact vessel to which it wasregistered. Knowing which vessel is in distress allows the rescue services to eliminatefalse alarms and launch an appropriate rescue.The Precision 406 also has a secondary distress transmitter. This transmits on121.5MHz and is used for “homing” purposes. When the rescue services get close,this allows them to direction find on the signal. To cater for searches at night, thePrecision 406 has a bright flashing light that aids final visual location.SEALREADYTESTPRESS TOAntennaStrobeGreen lampProgram pointSea contactsLanyardON buttonunder hereREADYbuttonBattery expiry dateRed lamp* If the programmed identity is a Radio Call Sign (RCS) then accuracy is limited to 5km
64 DESCRIPTIONThe Precision 406 is a powerful self-contained distress transmitter. It is powered by alight weight Lithium battery that has a replacement interval of 5 years. An EPIRB isintended to be a one-shot device; once activated it can operate for at least 48 hours. Itoperates best while floating in water, but it can also be operated while on board or in aliferaft.Refering to the previous figure, the key components of your Precision 406 are asfollows:Antenna This is a flexible whip. It must be near vertical whenoperating.If the antenna gets bent, gently straighten it out.Strobe light This is the glass U-tube visible through the clear lens dome.When the Precision 406 is activated this will flash every fewseconds.Red lamp Visible through the clear lens dome at the rear of theEPIRB. This stays on or flashes to show you which modeyou are in.Green lamp This flashes when the GPS gets a position fix.Program point A dimple in the clear dome, through which your supplier canoptically input the coded message unique to your Precision406. You must register the coded message with localauthorities.READY button Press this key once to de-activate the EPIRB. Hold it downto run the built-in self-test, which checks basic operation.ON button Press this key to activate the Precision 406 manually. Thekey is protected by a sliding door which is fitted with atamper seal.Sea switch The two screw heads below the keys are sea switchcontacts. Submerge these in water to automatically activatethe Precision 406.Lanyard Pull the lanyard spool down to free it. Use the cord to tetherthe Precision 406 to a survival craft.Never tie the Precision 406 to your vessel.4.1 Wall bracketIf you purchased the manually activated version (406m), this is normally supplied witha wall mounting bracket (see section 8). The bracket is made from white plastic so itwill not rust. Its top section is sprung loaded, so that one simple squeeze will quicklyrelease the Precision 406 allowing it to be carried to a liferaft. The wall bracket shouldbe sited in plain view near an emergency exit. This bracket is more than just a stowagepoint, it contains a magnet which disarms the EPIRB’s sea switch. If you do not stowthe Precision 406 in its bracket, there is a risk of it activating if it gets wet.
74.2 Float-free enclosureIf you purchased the automatically activated version (406a), also known as the “float-free” version, then your Precision 406 is supplied in a plastic enclosure (see section 9).This is much more than just a protective housing, it contains a sprung loaded leverwhich automatically pushes the enclosure lid off and releases the Precision 406 if yourvessel sinks. This automatic ejection is controlled by a device called a HydrostaticRelease Unit (HRU). If the enclosure is submerged then before it reaches 4 metres (13feet) deep the HRU cuts a plastic rod that holds back the spring and the lid is ejected,releasing the EPIRB which floats to the surface and switches on automatically.The diagram below illustrates the automatic release sequence:1. As the vessel sinks, the enclosure fills with water. The HRU contains ablade 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 theplastic rod, releasing the coil spring.2. The spring pushes the Precision 406 and the enclosure lid outwards. Asthe lid pivots off it disengages from the screw head that helped hold it inplace. The lid is weighted so it rolls over and falls away.3. As the Precision 406 floats away from the lid, it moves out of range of themagnet. Once away from the magnet its sea switch becomes armed.4. The sea switch activates. The EPIRB then floats on the surface with itsstrobe light flashing. After 3 minutes it makes its first distresstransmission.If you need to activate your Precision 406 manually, it can be freed from the enclosureafter pulling out the R-shaped retaining pin and removing the lid.HRU1) HRU cuts rod2) Lid ejects4) sea switch activates3) EPIRB arms onceaway from magnetMagnet
84.3 Manual Precision 406 in enclosureCustomers who need to mount their Precision 406 in an exposed position can selectthe protective enclosure without an HRU fitted (406c). This means that the Precision406 EPIRB will not float free if your vessel sinks. This is known as a category 2EPIRB. You can tell which enclosure you have by reading the category from the frontof the enclosure:406a Category 1 HRU fitted Automatic float-free406c Category 2 No HRU fitted Will not float free
95 CONTROLS5.1 ON buttonThis is hidden behind a sliding door, which protects it from accidental activation. Thesliding door has a tamper seal to show if the Precision 406 has been activated.The Precision 406 can be activated manually by sliding the door to the left (breakingthe seal) and then momentarily pressing the ON button.When activated the Precision 406 will start to flash immediately. It will not make anydistress transmissions for 3 minutes. This gives you a chance to turn it off if youactivated it accidentally. During this 3 minutes the red lamp illuminates continuously.When the red lamp starts to flash, the 3 minutes delay has passed and distresstransmissions have started. Normally the green GPS lamp will start flashing within thefirst 5 minutes.5.2 READY buttonThis button de-activates the Precision 406 and also tests the EPIRB.Ready Pressing and releasing this button quickly will de-activate thePrecision 406 and return it to its “ready” state. When the button isreleased the strobe and the red & green lamps will stop flashing.Self-test Pressing and holding the ready button (for about 10 seconds) willallow the built-in self-test to run. When the button is held down thered lamp will come on for 4 seconds, then go off. During this timeboth the 121.5MHz homer and the 406MHz satellite transmitter make“safe” transmissions. If both of these test transmissions arrive at theantenna with sufficient power then the strobe light will flash 3 timesto tell you that all is well. If the red lamp does not come on, or thestrobe light does not flash within 10 seconds, then there is a fault;the Precision 406 should be taken to a service agent.5.3 Sea switchIt is important to realise that the only time the Precision 406 is completely off is when itis fitted in its mounting bracket or enclosure. As soon as you take it out, a magneticswitch activates and puts the Precision 406 into its “ready” state. It will not drain thebattery in this state, but it will turn on automatically if the sea switch contacts arebridged by water. The sea contacts are the two exposed screw heads beside the rearswitches.Although you can control the Precision 406 manually with the READY and ONswitches, the sea switch overrides any manual settings. For the manual switches tooperate properly the Precision 406 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. Ithas to be wet for at least 2 seconds before it will activate and it has to be dry for atleast 8 seconds before it will de-activate.READYHOLD TOTEST
105.4 Lamps5.4.1 StrobeThe strobe is the visual means of locating the EPIRB. When activated, the strobeflashes 23 times per minute, with a pause during the time when the EPIRB istransmitting.The strobe is also used to indicate the result of a self test (see section 11.1).5.4.2 Red lampThe red lamp is used to indicate transmissions by the EPIRB. When activated, itflashes alternately with the strobe to indicate a good transmission on 121.5MHz. Every50 seconds it illuminates for 2 seconds to indicate a good transmission on 406MHz.When the EPIRB is first activated the red lamp is illuminated continuously until theEPIRB begins to transmit, when it begins to flash.The red lamp is also used to indicate the result of a self test (see section 11.1).5.4.3 Green lampThe green lamp flashes to indicate that a valid position has been obtained by the GPSreceiver. Every 50 seconds it illuminates for 2 seconds to indicate that the position isbeing transmitted on 406MHz.Every 20 minutes the GPS receiver updates its position information. If a fix is notobtained, the green lamp stops flashing, and illuminates only every 50 seconds (whenthe previous position information is transmitted).The green lamp is not used during self test.

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.6.1 SinkingIf you have a category 1 “float-free” enclosure (see marking on enclosure label), then ifyour vessel sinks, the Precision 406 will automatically release itself from its enclosurebefore it reaches a depth of 4 metres. The Precision 406 will float to the surface andstart to operate because its sea switch is activated.If possible, the Precision 406 should berecovered and tied (using its lanyard) toone of the liferafts. An EPIRB is meant tomark survivors, not the accident scene.For best operation leave the Precision 406floating in the sea near the liferaft.6.2 Abandon shipIf the vessel is sinking and there is time to fetch the EPIRB then this should always bedone. Release the Precision 406 from its mounting bracket as described in section 6.3or 6.4 and carry it to one of the liferafts. Once the liferaft is in the water, uncoil thelanyard and tie it to the liferaft, then throw the Precision 406 overboard so that it floatsnext to the liferaft. The Precision 406 will operate because its sea switch will activate.6.3 Releasing Precision 406 from a wall bracketIf you have an Precision 406 fitted into a wall bracket then follow the instructions belowto release it from the bracket:
126.4 Releasing Precision 406 from an enclosureIf your Precision 406 is fitted inside a full enclosure then follow the instructions belowto release it manually from its enclosure:6.5 Manual activationIf the vessel is not sinking, but there is imminent danger, then remove the Precision406 from its bracket and activate it manually as shown below. Note that once activatedit will flash immediately, but it will not transmit a distress call for 3 minutes. This givesyou a chance to turn it off if you activated it in error.Once activated the Precision 406 must have its antenna near upright and it must havea clear view of the sky for proper operation. Lying it on its side or placing it next to ametal wall will impair its range and may fail to alert the rescue services. Avoid handlingthe antenna, as this will also impair performance.21Pull R-clipfrom pinPullcoveroff3Pull EPIRBtowards you123switchesLocateon rearPress ON button4EPIRBwill flashSlide cover to leftBreaking tamper sealDo not let EPIRB fall out

This isnecessary to ensure that the next time it gets used it will operate for the full 48 hoursrequired by government regulations. See section 11.3 for battery replacementinstructions.6.8 Re-fitting Precision 4066.8.1 Refitting into wall bracketThe Precision 406 is now in its “ready” state, but its sea switch is still armed and willactivate if it gets wet. To de-activate the Precision 406 fully it must be returned to itsmounting bracket, where a magnet hidden in the bracket will make the Precision 406safe.
146.8.2 Re-fitting into enclosure• Offer Precision 406 into backplate with switches facing outwards.• Engage base of Precision 406 into D shaped metal prongs.• Antenna rests either to left or right of release pin.• Check Precision 406 is fully engaged in metal prongs and resting onfoam pad.• Refit cover by first locating release pin through hole in cover.• Locate cover onto backplate, then snap down over locating lug.• Refit R-clip through hole in end of release pin.3Fit coverover pin4Snap cover ontolocating lug5Fit R-clipthrough pin12SwitchesfacingoutFit D-shapedfoot into prongsCAUTIONFailure to fit EPIRBcorrectly may impairits ability to float freein an emergency
157 FALSE ALARMSFalse alarms are a serious problem for the rescue services. About 90% of EPIRBinitiated distress alerts turn out to be false alarms. If your EPIRB should cause a falsealarm, follow the instructions below.7.1 Stand down rescue servicesIt is most important that you contact the nearest search and rescue authorities and tellthem it was a false alarm, so that they can stand down any rescue services. Use anymeans at your disposal to make contact. Often this can be by VHF radio to the localcoastguard or mobile phone if you are within coastal range, but MF/HF DSC andInmarsat A, B, C,M may also be used. Useful contacts are:Country Region Telephone What to reportAtlantic / Gulf of Mexico (212) 668 7055Pacific (510) 437 3700USAFrom any location (800) 323 7233UK From any location 01326 317 575EPIRB Unique ID (UIN)Date, time & durationCause of activationLocation when activated7.2 De-activate the EPIRBIf the Precision 406 was activated by mistake, then de-activation is simple:• Remove the Precision 406 from any water and dry its sea switchcontacts.• Wait about 8 seconds for the sea switch to de-activate.If the Precision 406 is still flashing then it must have been turned on manually:• Slide the switch cover fully to the right.• Press and release the READY button.• The Precision 406 should now stop flashing.• Refit the Precision 406 correctly into its mounting bracket or enclosure.Modern EPIRBs have sea switches and it is not uncommon for the sea switch toactivate in rough seas or heavy rain simply because the EPIRB has been badly fitted inits mounting bracket. The Precision 406 bracket has a hidden magnet to hold thePrecision 406 in an off state. If the Precision 406 is wrongly fitted the magnet does notdo its job and heavy seas may activate the sea switch. The simple cure is to ensurethe Precision 406 is correctly fitted as shown in sections 6.8 or 6.8.2.
167.3 Dealing with a transmitting Precision 406In the unlikely event that your Precision 406 develops a fault and will not turn off, thenprevent its radio signal from reaching the satellite using one of the following methods:• Remove the antenna. Wrap the Precision 406 in metal foil and take itbelow decks.or• Remove the antenna and place the Precision 406 in a metal container orlocker.Leave it in this condition for 3 days until its battery is dead. See section 11.4 forinstructions on returning the Precision 406 for servicing. See also section 12.
178 WALL BRACKET INSTALLATION8.1 SitingThe wall bracket should ideally be sited in plain view near an emergency exit. Whenchoosing a suitable mounting position you should also consider:• Ease of access in an emergency.• Mount at least 1 metre (3’) from any compass equipment.• Allow at least 25mm (1”) above the bracket for it to spring open.• Allow 18cm (7”) for the antenna. Heavy bending of the antenna is bad.8.2 Mounting procedureThe wall bracket is supplied with a set of stainless steel fixings 25mm (1”) in length.The bracket mounts against a flat surface using 4 fixing points. Offer the bracket intothe chosen position and mark through the mounting slots. If you are using the nuts andbolts supplied, drill 6mm (1/4”) holes in the centre of each mark. You will need a 4mmAllen key to tighten the bolts. If the rear of the mounting surface is inaccessible thenuse the self-tapping screws supplied and drill 3mm (1/8”) holes. Always fit washersunder the heads of the screws to avoid damage to the plastic.175mm(7")130mm25mm(1")29mm(1.14")59mm(2.32")55mm(2.16")240mm(9.5")115mm(4.5")(5.1")
188.3 Mounting instruction plate The Precision 406 is supplied with an instruction plate. This is a rigid plate with basicvisual instructions for how to operate the Precision 406 in an emergency. The platevaries slightly depending on whether you have a wall bracket or a full enclosure. Thewall bracket version is illustrated below.The instruction plate should be mounted next to the EPIRB so that it is easily visible inan emergency. Use the four self-tapping screws supplied to mount the plate. Mountingdimensions are shown in the diagram above, or you can use the plate itself at a drillingguide for the screws.During vessel maintenance, ensure the plate does not get painted over or cleaneddown with strong degreasing solvents.VRV2134558.4mm (2.3")70mm (2.75")130mm(5.1") 116.3mm(4.58")Mount platenext to EPIRB
199 ENCLOSURE INSTALLATION9.1 SitingThe enclosure should be mounted upright against a vertical bulkhead. Alternately, itmay be mounted horizontally on a flat surface, such as a cabin roof. No otherorientations are recommendedIf you have a float-free Precision 406 it is critical that you choose a position where thereleased EPIRB will not get trapped by overhangs, rigging, antennas etc, shouldthe vessel ever sink. An expanse of flat surface is required to allow the enclosure lid toeject. Use the list below to choose a suitable mounting position:• Mount on the outside of the vessel’s structure.• 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 procedureThe enclosure mounts against a flat surface using 4 fixing points. See illustration formounting dimensions, or use the backplate of the enclosure as a marking guide. To dothis, pull out the R-shaped clip and remove the enclosure lid. Note how the Precision406 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 areusing the nuts and bolts, drill 6mm (1/4”) holes where you have marked. You will need
20a 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 toavoid damaging the plastic.9.3 Mounting instruction plateThe Precision 406 is supplied with a rigid plate giving visual instructions on how tooperate the Precision 406 in an emergency. Mount this next to your EPIRB asexplained in section 8.3.9.4 Marking HRU expiryIf you are installing a float-free Precision 406 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 amarine environment. Hence the 2 years starts at installation and it is left to thecustomer to mark this date during installation. A date 2 years into the future should bemarked on the HRU body and copied onto the label on the side of the enclosure. TheHRU is marked by cutting out the corresponding dates on its label. The enclosureshould be marked using the alpha-numeric stickers provided, then covering them withthe clear sticky label provided (but see 9.5 first). The preferred date format is monthand year, for example : JUN 2001.150mm(5.9")84mm (3.3")44mm(1.73")104mm(4.1")150mm(5.9")440mm(17.3")140mm(5.5")OBSTRUCTION FREE AREA0.8m x 0.5m (32" x 20")
219.5 Marking vessel nameIn most countries it is usual to have your EPIRB programmed by your supplier with thevessel’s existing “callsign” (see registration section below). Your supplier will then markall 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 vesselname. In these countries it is left to the customer to mark the vessel name duringinstallation.The name must be marked on the rear of the Precision 406 itself and also on theenclosure, if you have one. Use the alpha-numeric stickers provided to mark the vesselname (or its abbreviation) on the top line of the Precision 406's rear label and again onthe enclosure label. Protect the markings with a section of the clear sticky labelprovided.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 leads to monetary forefeit.
2210 REGISTRATION10.1 OverviewEvery EPIRB is pre-programmed with a unique identity before it reaches the customer.This is done by the manufacturer or in some cases the distributer. The identity includesa 3 digit country code. This is the country that takes responsibility for storing thatparticular EPIRB’s registration details. In most cases this is the country to which thevessel is flagged. The country programmed into your Precision 406 can be found fromits rear identity label. You must register with this country.MV BELLANAEPIRB 11D1400063F81FE0FLAG 232 G BRITAINSERIALISED 000012CATEGORY 1 – AUTOClass 2 –20/+55 C (-4/+131 F)When you activate your EPIRB in an emergency, the nearest maritime search andrescue coordination centre (MRCC) will receive the message and decode the countrycode (eg 232). They will then access the registration database for that country andexpect to find details of your vessel, its radio equipment and who to contact. If they failto find this information, this may slow down any rescue.10.2 How to registerThree registration forms are provided, two are for future use and one must becompleted now. The forms are all pre-printed with your EPIRB’s identity, all you haveto do is complete details of your vessel and provide some contact numbers. Whereverpossible the forms are also pre-printed with the correct mailing address and a faxbacknumber. If your form does not have a mailing address, contact your supplier. Whenyou have completed the form, you can choose to fax it or mail it.It is usual to receive confirmation when you register. In the USA you will also receive a“Decal” sticker which you must fit to the Precision 406 itself. The Decal is proof ofregistration. Not having a Decal is an offence.

(See warranty section for address).For most other countries, the EPIRB must be re-programmed with either the newvessel’s Maritime Mobile Station Identity (MMSI) or its radio callsign, whichever isrequired by the country controlling the new vessel.Since the EPIRB identity contains a country code, it follows that changing the flag stateof the vessel also means the EPIRB must be re-programmed.Programming can be carried out at Pains Wessex or any of our designated agents. Fordetails of your nearest agent, either contact McMurdo using the details in the warrantysection, or visit the McMurdo web site at www.mcmurdo.co.uk.
2411 MAINTENANCE11.1 Monthly self-test & inspectionAs an important item of safety equipment, your Precision 406 should be checkedregularly. It has a built-in test capability that can be used as a confidence check. Thisself-test confirms that the battery is healthy, that the GPS receiver and both of thedistress transmitters are functional and that the strobe light is operational. The self-testshould be performed monthly. It should be performed during the first 5 minutes of thehour, to minimise disturbance on the emergency channel.If your Precision 406 is in an enclosure it can be tested through the test windowwithout having to remove the Precision 406 from the housing. If you have a bracketmounted Precision 406 it will have to be removed from the bracket as described insection 6.3. The procedure for self-testing is as follows:• On rear of Precision 406 press and hold the READY button.• The red lamp will come on for 4 seconds to confirm test in progress.• When the red lamp goes out, the strobe lamp must flash 3 times (atleast).• If the strobe does not flash, or the red lamp illuminate, repeat the testthen see section 11.4.During these monthly checks you should take the opportunity to visually inspect thePrecision 406 and its mountings for deterioration or damage.On the Precision 406 itself check the following:• Inspect the Precision 406 for any obvious damage.• Check there is no sign of water inside the unit.• Check that the lanyard is not tied to the vessel structure.• Check the battery is within its expiry date.If you have a wall bracket:• Confirm the bracket top clip springs up when squeezed.• Check the Precision 406 is correctly fitted and secure in its bracket.If you have an enclosure:Check the HRU is within its expiry date (category 1 only).Confirm the cover can be manually removed with ease.Ensure the Precision 406 base is correctly fitted into the D-shaped prongs.If the EPIRB or its mounting needs cleaning then this should be done using warmsoapy water and a damp (not wet) cloth. Do not use strong detergents or solvents.Do not paint the Precision 406 or its mountingDo not clean with detergents or solventsDuring vessel cleansing or painting remove the Precision 406 and its mounting.
2511.2 HRU replacementIf you have an Precision 406 in an enclosure marked Category 1 then it contains aHydrostatic Release Unit (HRU). This has a 2 year replacement interval. The expirydate, which is marked on the HRU and on the enclosure side label should be checkedregularly.When the HRU expires you can obtain a replacement at a local chandler, or directfrom McMurdo at the address shown on the warranty page. McMurdo will supply anHRU kit (Part No. 82-210B) complete with breakable plastic rod, date labels andinstruction 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 metal 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.• Slide EPIRB into D-shaped foot on lever arm, switches outermost.• Refit cover by engaging hole over rod and then snapping into place.• Refit R-clip through top of rod.• On side of cover, remove old HRU expiry date and mark new date.12Breakable rodHRULever armSpringEngagewasher hereRear E-clipFitting HRUWasher
