iiIntroductionMcMurdoMcMurdo has supplied the maritime market for many years with communicationproducts of high quality and excellent design, and considers it of utmost importancethat all products are safe and easy to operate.The productThe McMurdo F1 DSC VHF Radiotelephone (radio transceiver) is designed to meet thehigh quality standard required for a product that plays an important role in the safety ofthe ship and its crew. The F1 DSC Radiotelephone is easy to operate and gives theuser high quality effective radio communication to other ships as well as to shore basedstations. Installation and maintenance is made very simple and can be carried out byuntrained personnel.Training certificateThe F1 DSC Radiotelephone is very simple to use; the menu-structured operation isuser-friendly, self-explanatory and simple to navigate. However the use of VHF marineradios including DSC is legislated; it is therefore necessary for the user to have acertificate from the legislating authority in the country where the radio is to be used.When the radio is registered the legislating authority will issue the MMSI numbernecessary for the operation of the DSC function.A CD-ROM simulating the operation of the F1 DSC Radiotelephone can be obtainedfrom McMurdo on application. This, when installed on a PC-compatible computer,simulates the operation of the F1 DSC Radiotelephone together with a simulation of asecond station for exchange of DSC messages.ServiceMcMurdo has established a worldwide service network ready to support anyrequirement concerning the F1 DSC Radiotelephone. The service network ensures thatspare parts and installation advice can be obtained in all major ports of the world. TheCertified Services Centre concept ensures that the performance of the Service Centresis constantly monitored and that the skills of the personnel are up to date.Details of the McMurdo worldwide service network can be found on the website:www.mcmurdo.co.uk
iiiMaintenanceThe F1 DSC Radiotelephone is an essential part of the ship’s emergency system. Asthe radio is a vital component for the safety of the ship and its crew it is very importantto maintain the radio and its installation to a very high standard. The design of the radioensures that maintenance can be kept to a minimum, however it is good practice toperform a functional check at least once every month. This functional check isdescribed in this manual and takes only a few minutes to carry out. It is essential toperform a functional check following installation. It is also important to inspect all cablesand connections at regular intervals, such as twice yearly.DisclaimerInformation contained in this manual is supplied in good faith, but is liable to changewithout notice.

ivInstalling and Using the Transceiver SafelyInstallation WARNING: Do not connect the transceiver to a mains (line) AC electrical supply, as anelectric shock or fire hazard could result. CAUTION: Do not connect the transceiver to a DC supply exceeding 16V or reverse thesupply polarity. Damage to the transceiver can result. CAUTION: Do not bypass the power cable inline fuse (such as cutting the cable shorter). CAUTION: The transceiver is designed for operation in the temperature range –15°C to+55°C. Do not install (or use) the transceiver in areas which exceed this range. CAUTION: The F1 DSC radio is water resistant to international standards. However, if eitherthe transceiver or microphone casing is damaged (e.g. due to heavy impact) then the sealingcannot be guaranteed. WARNING: Do not install the receiver in a position where;a) the controls of your vessel may be obstructed.b) it may obstruct your normal movement around your vessel.c) it may cause bodily injury.d) it cannot be easily accessed in an emergency.Use WARNING: Certain parts of the chassis can become hot during extended periods of operation,notably the rear panel (connectors and radiator fins). Avoid touching these areas when the radio isoperating. WARNING: Do not touch the rear connections, notably the antenna connector, when thetransceiver is operating and do not touch the antenna whip (mast) or connecting cable whenoperating the transceiver, for RF exposure and electrical safety reasons. Refer to RadioFrequency Exposure Warning. WARNING: Opening the transceiver cover will invalidate the warranty. Do not open the coverwhen the transceiver is operating, or connected to a power supply.Maintenance CAUTION: Avoid using chemical solvents to clean the transceiver as some solvents candamage the case material.NOTE: The transceiver contains no user serviceable parts. Return to your Service Agent forrepair.
vRadio Frequency Exposure WarningTo meet the current requirements for Radio Frequency Exposure it is necessary toinstall the antenna mast correctly and operate the equipment according to theinstructions.The assumptions used in this assessment are: full transmit power is used, a goodantenna is used (assumed to be a 9dBi gain omnidirectional type).Where no suitable structure exists to achieve a 3 metre vertical separation then theantenna base must be mounted at least 1 metre above the head of any person withinrange and all persons must stay outside the 3 metre safety radius.Failure to adhere to these limits could expose persons within the 3 metre radius to RFradiation in excess of the MPE / SAR limits.Rules of OperationLicensingPlease refer to the F1 DSC Radiotelephone Operation Manual for full radio operatingprocedures.IMPORTANT: In most countries the operator of the transceiver must possess acurrent radio telephone licence, and the equipment must be registered (Call Signand MMSI number). Please contact the relevant authority in your country formore information.IMPORTANT: Normal users of the transceiver should be trained, licensedoperators, but this rule is waived in an emergency and any person can transmit aDistress Call. WARNING: The antenna mast must be mounted at a minimum distance(vertical separation) of 3 metres from the head of any person standing on deckto meet international safety directives on Maximum Permissible Exposure(MPE) / Specific Absorption Rate (SAR). WARNING: Do not transmit when persons are closer than 3 metres to theantenna. If any person (e.g. the operator) must be closer, then a grounded RFshield should be interposed between that person and the antenna.

Page 1Installing the MMSI numberTo ensure full performance of the F1 DSC Radiotelephone it is essential that the MMSInumber is installed in the radio.Applying for a MMSI numberIt is necessary to apply for a radio licence and a MMSI number to the national authority,which in most cases has a standard form to be completed. In Britain the nationalauthority is the Radiocommunication Agency (RA); the standard form can be found onthe webpage www.radio.gov.uk, then follow the menu items: M – Maritime radio –Application forms – RA145. The supplier of the radio will be able to advise concerningthe procedure and form used to apply for a radio licence including the MMSI number.How to install the MMSI number The MMSI number is a 9-digit number which is programmed into the radio. Whenprogrammed once it is not possible for the operator to alter the number withoutreturning the radio to the supplier or to McMurdo Ltd.To program the MMSI follow these illustrations:1. Turn on the Radio2. When the radio shows the standby displayPress the Menu action key3. Use the scroll key to display the menu“Profiles” and press the Select action key4. Use the scroll key to display the menu“MMSI number” and press Select action key5. The first option displayed is“Ship MMSI”. Press the Select action key6. The cursor will be placed behind the last 0Use the Clear action key to delete all 0’sthen key in the MMSI number7. The MMSI number is saved by pressing the Save action key49° 45` W at: 11:23123°32` E UTCMenu 16 PosProfilesSelect ExitProfilesMMSI numberSelect BackMMSI numberShip MMSISelect BackShip MMSI numberMMSI:000000000Save Clear WARNING: If no MMSI number is installed the radio will be unable to transmita DSC call including the transmission of a DSC distress alert.
Page 2IMPORTANT: If the wrong MMSI number has been entered, it is possible to re-enter(correct) the MMSI number once more only. However, after one hour from the time ofentering the first MMSI number the radio will inhibit changing the MMSI number.If this happens, the radio must be returned to McMurdo (via the supplier) forreprogramming to allow entering another MMSI number.
Page 3Mounting optionsIntroductionTo ensure high performance of the F1 DSC Radiotelephone it is very important that theinstallation guidelines described in this book are followed.When installed make sure the radio is fixed to a solid surface. The mounting surface towhich the radio is fixed must be as solid and as free of vibrations from the ship's engineor other vibration generating sources as possible. Extensive vibrations can damage thecommunication quality and in the worst case make communication impossible.Cables specified in this installation manual are recommendations only, but to achievethe full performance of your radio it is advisable to follow these recommendations. Thecables specified are not shielded, but it is recommended to use shielded cables whenother electronic instruments are mounted close to the radio. Special attention has to bepaid to cables from another instrument running parallel to the cables for the F1 DSCRadiotelephone and to cables carrying high alternating current. Such cables can causeradio interference, which can disturb communication on one or more of the VHFchannels.The F1 DSC Radiotelephone uses components containing magnets. To ensure correctoperation of your compass, it is necessary to mount the radio transceiver no closer than0.5 metres to any compass installed in the vessel.The VHF communication range is limited to line of sight. It is therefore very importantthat the antenna is installed as high and as free of obstacles as possible. It is alsoimportant to ensure that the connection from the antenna to the radio uses a 50Ω lowloss cable, and that the connectors used are of the recommended type and fit the cableused. The recommended coax cables RG58 and RG214 or equivalent must be installedwith caution; it is a good principle not to bend the cables to a smaller radius than 10times the cable diameter. In sailboats the antenna is often installed at the top of themast, requiring a long cable between the radio and the antenna. To obtain themaximum performance of your radio it is recommended to use a low loss coax cable;the RG214 is a low loss cable.The F1 DSC Radiotelephone is watertight; if installed following the instructions in thismanual, the complete installation will be watertight also. When installing in a bulkhead itis recommended to use the McMurdo bulkhead installation kit, which is available in twoversions: a bulkhead mounting kit and a flush mounting kit. Both kits will when installedwith care create a watertight seal. WARNING: Observe the Radio Frequency Exposure Warning in the frontsection of this manual regarding installation of the antenna.
Page 4Tabletop or ceiling installationThe F1 DSC Radiotelephone can be mounted on top of a table or on the ceiling. Thesupplied bracket is used to mount the radio in these positions. The mounting bracket issupplied with 6 installation screws; it is recommended to use all 6 screws.(See ‘Drilling guides; on page 9.)Before the bracket is fixed to the table or the ceiling make sure that there will beenough room for the radio and the cables. The main dimensions are shown in thefigures below.When the tabletop bracket is mounted, install the radio and find the angle that will bemost suitable for operating the radio, then tighten the lock knob. When the radio is inposition in the bracket connect the necessary cables, but make sure that enough cablelength is available for future readjustment of the radio.

Page 6Bulkhead or panel mountingFor bulkhead or panel mounting of the F1 DSC Radiotelephone two mounting kits areavailable: a flush mounting kit and a simple bulkhead/panel mounting kit.Flush mount kit (kit number 84-412)The flush mounting kit when installed properly provides a watertight installation of theradio in a bulkhead or instrument panel. Before the hole is cut in the bulkhead or theinstrument panel, make sure that the space behind the bulkhead or instrument panel issufficient to accommodate the radio and connecting cables. In the illustration thedimensions of the required space are shown. The illustration also shows an explodedview of the assembly process.A cutout template is provided in the flush mounting kit; take particular care to beaccurate when cutting the hole. If the hole is too large the installation may not bewatertight or the installation may appear untidy.When using the flush mount kit the connection point for the fist mike must be changedbecause the flush mount covers the usual connection of the fist mike at the bottom ofthe fascia. As shown below the fist mike connection becomes part of the flush mountkit. A wire loom is provided to connect the fist mike to the rear of the radio.

Page 8Bulkhead and instrument panel mounting kit (kit number 84-413)Use of the bulkhead and instrument panel mounting kit is a simple way to build in theF1 DSC Radiotelephone. Screws are provided with this mounting kit. Before the hole iscut in the bulkhead or the instrument panel, make sure that the space behind thebulkhead or instrument panel is sufficient to accommodate the radio and connectingcables. The dimensions of the required space are shown in the illustrations below. Notethat unlike the Flush Mount Kit (see page 6) the panel thickness is limited to 12mm dueto the slightly different construction of the Simple Bulkhead/Panel Kit.A cutout template is provided in the mounting kit; take particular care to be accuratewhen cutting the hole. If the hole is too large the installation may not be watertight orthe installation may appear untidy.

Page 11Electrical connectionsIt is recommended that this guideline for electrical connection of the F1 DSCRadiotelephone is followed as carefully as possible. A careless installation is likely todegrade performance of the radio and cause difficulties for the operator. Most radioinstallations will be undisturbed for many years so it is therefore important that thematerials chosen are suitable for use onboard ship where they will be in contact withthe harsh environment onboard.The radio will operate when it is connected to the power supply and to the antenna.These are the only two connections which are necessary for full functionality of theradio. However, if the radio is connected to a GPS source, position information storedin the radio will be automatically updated at regular intervals and it will not benecessary to update this position manually. Connection to a GPS will ensure that theposition transmitted in a DSC distress call is as accurate as possible.In an environment with considerable electrical noise the earth screw at the rear of theradio should be connected to a common earth point. This is particularly important whenthe radio is installed together with MF/HF radios. It is also advisable to route power,data and antenna cables away from sources of electrical noise such as an engine.An external loudspeaker can be connected to the two central pins in the power plug(see page 13). The external loudspeaker can be switched on/off via the SpeakerSettings (in Profiles).An additional fist mike can be connected via the 15 pole D-sub connector at the rear ofthe radio. This additional connection is in parallel with the fist mike attached to the front.Connection of power supplyThe power supply is connected as shown. If it is necessary to extend the wires from theconnector, the wire dimensions should be as specified.The nominal power supply voltage is 12V. The radio will operate over the supply rangeof 10.8 VDC to 15.6 VDC. If it is necessary to connect the radio to a 24V battery, a 24Vto 12V voltage converter must be used.The F1 DSC Radiotelephone is protected against reverse voltage polarity by an internaldiode and fuse. If reverse polarity is applied to the radio the internal fuse will open (fail)and must then be replaced by a service agent. WARNING: You must fit an external inline fuse with a 8A fast blow rating in thepositive (plus) supply cable (see page 12). CAUTION: The battery negative or positive terminal must not be connected tothe earth screw under any circumstances, as this may cause electrolytic corrosion. WARNING: The F1 DSC Radiotelephone will in most cases be connected to theship's battery. During installation special care must be taken not to short the batteryterminals as this can cause severe burns, or in the worst case can cause a fire.

Page 14Connection of GPS for position informationThe position information used in the DSC distress message can be entered manuallyfrom the keyboard, but to ensure that the position information is valid at all times a GPScan be connected to the radio. The information transmitted from a GPS uses astandard interface, designated NMEA 0183. The F1 DSC Radiotelephone can beconnected to this GPS interface directly via the two wires to the 15 pin D-subconnector.The NMEA protocol transmits the position information via named sentences. Thenamed sentences that can be used are: GGA, GLL, GNS, RMC and ZDA.Table 3 Recommended wire size for connection of GPSIf it is necessary to use longer wires than those provided with the radio, wiredimensions as specified should be used. As the GPS connection is sensitive toelectrical noise use of shielded twisted cable is recommended.GPS From To Wire mm2Maximum lengthNMEA 0183c F1 DSC GPS 0.25 5.0mNMEA 0183c F1 DSC GPS 0.50 10.0m
Page 15Connection of fist mike to the rear D-sub connector (socket)When the flush mounting kit is used for bulkhead or instrument panel installation of theF1 DSC Radiotelephone it is necessary to connect the fist mike to the D-sub connectorat the rear of the radio. A wire loom is provided to connect the fist mike to the rear ofthe radio. The illustration below shows how this loom is connected.
Page 16Connection of fist mike to the D-sub plugIf for a particular installation the attachment of the fist mike to the front of the radio isinconvenient, the mike can be connected to the D-sub connector at the rear of theradio, as shown.Table 6 Connection of fist mike to D-sub connectorFISTMIC REAR CONN.

Page 17Connection of antennaThe antenna and the antenna cable are a very important part of the radio installationand it is therefore very important to use good quality materials. The antenna must bemarked as a VHF antenna covering at least the frequency band from 153MHz to163MHz. VHF antennas for use on leisure ships typically have 0dB or 3dB gain(although specialised antennas may have gains as high as 9dB). Depending on theenvironment, the 3 dB gain antennas can give better coverage and together with a lowloss antenna cable will ensure greater radiated signal power and better receiversensitivity.When securing the antenna plug to the coax cable make sure that the cable isprepared to the dimensions shown in the illustration below. A frequent cause of poorcommunication is that the antenna connection is faulty, therefore make sure that thisconnection is properly made and that it is inspected at regular intervals.
Page 18Table 4 Coax cable signal lossesTypical cable losses for two common types of coaxial cable.Cable type Cable loss per meter for VHF channelsRG 58 2.0 dB/10 meter cableRG 214 0.8 dB/10 meter cableLine of sightAs a general rule the VHF communication range is the same as the line of sightdistance, which means that the receiver antenna must be able to see the transmitterantenna. Line of sight depends on eye height above water level of the transmitter andof the receiver. As the “eye” of the radio is the antenna, the communication rangedepends on the height above water level of the antennas.The illustration shows the line of sight (the curvature of the Earth is exaggerated forclarity).Table 5 Line of sight distancesh2 (m)0.5 1 3 5 10 300.5 3.1 3.8 5.4 6.6 8.6 13.813.8 4.5 6.1 7.2 9.3 14.435.4 6.1 7.7 8.8 10.9 16.156.6 7.2 8.8 10.0 12.0 17.210 8.6 9.2 10.9 12.0 14.1 19.3h1(m)30 13.8 14.4 16.1 17.2 19.3 24.4h1 and h2 are the heights above sea level of the transmit and receive antennas.Distances are in nautical miles.
Page 19Performance checkTo make sure that the radio performance is satisfactory, it is advisable to carry out aperformance check of the radio installation at regular intervals.• Installation, cables, connectors and antenna should be visually inspected atleast once a year.• A performance check as detailed below should be carried out at least everymonth.• A performance check as given below should be carried out after installation orrepair.Performance check1. Turn the radio on.2. If a GPS is connected to the radio wait until position update is found.3. If no GPS is connected to the radio, key in a valid position and time.4. Adjust the squelch and make sure that the squelch can silence the radio.5. Make a telephony call to a coast station:• Ask for radio check6. Make sure that the coast station operator can read you clearly and that youcan read the coast station clearly.7. If the called coast station is capable of receiving DSC messages, ask for aDSC test call to be made; make sure that the coast station MMSI is at hand.8. Make an individual DSC call to the coast station.9. Wait for acknowledgement.10. When acknowledgement is received, call the coast station on the suggestedworking channel to confirm that the test has been carried out successfully.For instructions on how to use the F1 DSC Radiotelephone and set up a DSC call seethe Operation Manual.
