NMEA® and NMEA 2000® are registered trademarks of the National Marine Electronics Association.Navico recommends that you check the radio operating licensing requirements of your country before using this VHF radio. The operator is solely responsible for observing proper radio installation and usage practices.Notes on MMSI and DSCThe user MMSI (Marine Mobile Service Identity) is a unique nine digit number. It is used on marine transceivers that are capable of using DSC (Digital Selective Calling). Digital Selective Calling offers significant safety and convenience advantages over older VHF radios without this functionality. ¼Note: many countries do not have radio repeaters that support DSC message relaying. However DSC can still be useful for direct ship-to-ship communication, where the other vessel is also equiped with a DSC capable radio. You must obtain a user MMSI and enter it into your radio in order to use the DSC functions. Contact the appropriate authorities in your country to obtain an MMSI number - charges may apply. If you are unsure who to contact, consult your Lowrance dealer.
6 | | Link-6 operator manual ¼Note: DSC distress calls generated by this radio are limited to the same range restrictions that apply to regular VHF transmissions. The vessel sending a distress can only rely upon DSC if within range of a GMDSS Coast Radio Station. Typical VHF range may be about 20NM, though this varies greatly depending upon installation, antenna type, meteorological conditions, etc.About this manualThis manual is a reference guide for installing and operating a Link-6 VHF radio.

| 25DSC call menu | Link-6 operator manualDSC call menuDSC (Digital Selective Calling) is a semi-automated method of establishing VHF, MF, and HF radio calls. One big advantage that DSC enabled radios offer is that they can receive calls from another DSC radio without being on the same channel as the calling radio. The calling radio will provide details on what channel to switch to so that voice communication can be established. There are various types of DSC calls - the type of call made determines information sent with the call, and how other radios respond to the incoming call. The following options are available when the DSC button is pressed;DSC callsThere are four call types, as well as related options, that can be accessed from this menu; IndividualUsed to place a call to a single other vessel. The call can be initiated by selected an existing vessel in the CONTACTS; by entering in a new vessel’s MMSI (MANUAL); or by selecting a vessel in the RECENT list. When the SEND TO page is displayed, turn the channel knob to select the channel to use for voice communication.DistressThe distress menu can be accessed via the DSC Calls menu, or directly by a short press of the Distress key on the front of the radio.The nature of the distress call must be selected from the list of options - this will be displayed on other radios receiving the call.After the Distress Call is sent, the radio waits for an acknowledgment.3
26 | DSC call menu | Link-6 operator manualThe Distress Call is automatically re-sent every 3.5 to 4.5 minutes until a distress acknowledgement is received.Alternatively the operator can select:RESEND (under OPTION - access by pressing the Menu/DSC button) used to immediately resend the Distress CallPAUSE (under OPTION - access by pressing the Menu/DSC button) used to pause the automatic Distress Call resend timerCANCEL (press ‘X’ button) to cancel the Distress CallIf a distress cancel is sent, the display shows PTT --> REASON, prompting the operator to state the reason for the cancellation. After a DISTRESS ACK is received, the alert should be silenced, and the reason for distress should be clearly stated, pressing the ‘PTT’ on the MIC and talking.The following information (if available) is contained in the Distress Call:• Nature Of Distress (if selected)• Position information (the latest GPS or manual input position is held for 23.5 hours, or until the power is turned OFF).GroupUsed to place a call to a known group of vessel, all using the same ‘Group Call ID’ (GCID) number. The call can be initiated by selecting an existing group from the group list, by entering a new GCID, or by selecting a group from the RECENT list.When the SEND TO page is displayed, turn the channel knob to select the channel to use for voice communication.

| 37Installation | Link-6 operator manualFirst startup conguration The first time the radio is powered up, the user is prompted to make a series of setting selections in order to allow the radio to perform to its full potential. Some steps must be completed; some are optional and can be completed later. The steps are outlined below for reference: Select the region and country the radio will be operated in. Enter MMSI number if known, or skip to next step. Re-enter number to confirm correct entry. ¼Note: MMSI entry can only be done once. Changing the MMSI requires radio be returned to a Lowrance dealer. For some EU region radios only: Enter the ATIS ID number. Re-enter number to confirm correct entry. Enter vessel call sign if known, or skip to next step.
38 | Installation | Link-6 operator manual Set the time offset for your region. Choose whether to display time in 12 or 24 hour.MMSI and ATIS IDThe MMSI is a unique 9 digit number and the ATIS ID is a 10 digit number. They are used on marine transceivers that have DSC (Digital Select Calling) functionality. • An MMSI remains with a vessel, even if the vessel is sold on.• An MMSI has 9 numeric digits (xxxxxxxxx). Your MMSI must not commence with a ‘0’.• A Group MMSI begins with ‘0’ followed by 8 numeric digits (0xxxxxxxx).• A Coast Station MMSI begins with 00 followed by 7 numeric digits (00xxxxxxx).• By law, you are not able to change your MMSI once it is entered into the radio. This is why there is the confirmation screen when entering the MMSI.• An ATIS ID is only required in certain EU countries when navigating some inland waterways. It is usually a different number to your MMSI.• If you need to have the MMSI in the radio changed, the radio must be taken back to your Lowrance dealer.ATISAutomatic Transmitter Identification System (ATIS) is required for vessels making VHF transmissions whilst on the inland waterways of the Regional Arrangement Concerning the Radiotelephone Service on Inland Waterways (RAINWAT) signatory countries. RAINWAT is an agreement to implement common principles and rules for the safe carriage of people and goods on Inland Waterways. The signatory countries are: Austria, Belgium, Bulgaria, Croatia, the Czech Republic, France, Germany, Hungary, Luxembourg, Moldova, Montenegro, the Netherlands, Poland, Romania, Serbia, the Slovak Republic and Switzerland.
| 39Installation | Link-6 operator manualWhere a VHF is required on the inland waterways of the signatory countries, this must be capable of ATIS transmissions, and have the feature activated. An ATIS number is required which is issued by Ofcom when you add one or more pieces of ATIS equipment to your Ship Radio Licence. If you don’t have a user MMSI or ATIS ID, contact the appropriate licensing authority in your country. If you’re unsure who to contact, consult your Lowrance dealer.
