3-6 GPS data and time (GPS/DATA)  
If the boat has an operational GPS navigation receiver and is connected by NMEA port, the  
VHF radio automatically detects and updates the vessel position and the local time.  
However, if the GPS navigation receiver is disconnected or absent, you can specify the vessel  
position and the local time manually, using the GPS/DATA option.  
This information is important because it will be used if a DSC distress call is transmitted.  
If GPS data is NOT available for some reason, the NO GPS alert will sound for 5 seconds (or  
until you press any key) and the radio requests you to enter the position data manually.  
This request is repeated every 4 hours if you do not enter the position data manually.  
After you have entered the position data manually, you must update it within 23.5 hours  
otherwise the NO GPS alert sequence repeats.  
The NO GPS warning will be shown whenever GPS data is not available from an operational  
GPS navigation receiver.

4-8 Weather alerts (WX ALERT)  
US model only.  
Use WX ALERT to set your preferences for weather alert information.  
The NOAA provides several weather forecast channels on USA and Canadian channel banks.  
If severe weather such as storms or hurricanes are forecast, the NOAA broadcasts a weather  
alert on 1050 Hz.  
The NOAA All Hazards Weather Radio Service (NWR) works in conjunction with the  
Emergency Alert System (EAS) to issue weather alerts for specific geographic areas or specific  
weather conditions. It uses a digital encoding system known as SAME (Specific Area Message  
Encoding) to broadcast these alerts.  
Each transmitter in the NOAA All Hazards Weather Radio Service (NWR) network is identified  
with a unique 6-digit SAME code. Each transmitter operates on one of 7 frequencies.  
Note: To activate a SAME alert, a SAME CODE (county ID) must be selected and turned ON  
(see section 4-8-2).  
4-8-1 TONE ALERT  
If TONE ALERT is ON and an alert tone of 1050 Hz is broadcast from the NOAA weather  
station, the weather alert is picked up automatically and the alarm sounds. Press any key to

Section 7 - Sending and receiving DSC Calls  
WARNING  
A valid USER MMSI must be entered into this radio before these DSC functions can be  
used. See section 5-1.  
7-1 What is DSC?  
DSC (Digital Selective Calling) is a semi-automated method of establishing VHF, MF, and HF  
radio calls. It has been designated as an international standard by the IMO (International  
Maritime Organization) and is part of the GMDSS (Global Maritime Distress and Safety  
System).  
Currently, you are required to monitor Distress Channel 16, but DSC will eventually replace  
listening watches on distress frequencies and will be used to broadcast routine and urgent  
maritime safety information.  
DSC enables you to send and receive calls from any vessel or coast station that is equipped  
with DSC functionality and within geographic range. Calls can be categorized as distress,  
urgency, safety, or routine, and DSC selects a working channel automatically.  
7-2 Sending DSC Calls  
You can call any other person that has another DSC equipped radio.  
Quick press the CALL / MENU key to access the following DSC CALL menu options – select  
LAST CALL to quickly call back the person who called you.  
Note that only four DSC CALL menu options can be shown on the LCD at any one time.  
Press + or – on the microphone or turn the Channel Select knob on the base station to  
scroll up or down through the menu until the cursor is positioned at the desired option.  
Press ENT (the center of the Channel Select knob) to display that option.

Section 9 - AIS functionality  
WARNING  
A valid USER MMSI must be entered into this radio before these AIS functions can be  
used. See section 5-1.  
9-1 About AIS  
The marine Automatic Identification System (AIS) is a location and vessel information  
reporting system. It allows vessels equipped with AIS to automatically and dynamically share  
and regularly update their position, speed, course and other information such as vessel  
identity with similarly equipped vessels. Position is derived from the Global Positioning  
System (GPS) and communication between vessels is by Very High Frequency (VHF) digital  
transmissions.  
There are a number of types of AIS device as follows:  
Class A transceivers. These are similar to class B transceivers, but they are designed to be  
fitted on large vessels such as cargo ships and large passenger vessels. Class A transceivers  
transmit at a higher VHF signal power than class B transceivers and therefore can be  
received by more distant vessels, and also transmit more frequently. Class A transceivers  
are mandatory on all vessels over 300 gross tonnes on international voyages and certain  
types of passenger vessels under the SOLAS regulations.  
Class B transceivers. Similar to class A transceivers in many ways, but are normally lower  
cost due to the less stringent performance requirements. Class B transceivers transmit at  
a lower power and at a lower reporting rate than class A transceivers.  
AIS base stations. AIS base stations are used byVesselTraffic Systems to monitor and control  
the transmissions of AIS transceivers.  
Aids to Navigation (AtoN) transceivers. AtoNs are transceivers mounted on buoys or other  
hazards to shipping which transmit details of their location to the surrounding vessels.  
AIS receivers. AIS receivers will generally receive transmissions from class A transceivers,  
class B transceivers, AtoNs and AIS base stations but do not transmit any information about  
the vessel on which they are installed.  
This radio contains an AIS receiver only function.  
9-2 AIS - Static and dynamic information  
Defined transmit rates for Class A vessels shown below are provided for reference purposes  
only. The frequency of messages received will vary due to a number of factors including but  
not limited to such factors as antenna height, gain and signal interference.  
Static information is either broadcast every 6 minutes, when data has been amended, or  
upon request.

9-3 Using the AIS receiver  
Providing that other vessels with AIS transceivers installed are within radio range of your  
vessel, you should see their details appear on the AIS plotter screen. These details are also  
repeated on the NMEA ports for display on a compatible chartplotter / MFD.  
Specific details of how to configure your chartplotter to make use of the AIS receiver features  
will be given in your chartplotter manual. If you are using charting software running on a PC,  
please refer to the instructions provided with your chartplotting software for details of how to  
configure it to display AIS information.

1. The transceiver will not power up.  
A fuse may have blown or there is no voltage getting to the transceiver.  
a) Check the power cable for cuts, breaks, or squashed sections.  
b) After checking the wiring, replace the 7 Amp fuse.  
c) Check the battery voltage. This must be greater than 10.5V.  
2. The transceiver blows the fuse when the power is switched on.  
The power wires may have been reversed.  
a) Check that the red wire is connected to the positive battery terminal, and the black wire  
is connected to the negative battery terminal.  
3. The speaker makes popping or whining noises when the engine is running.  
Electrical noise may be interfering with the transceiver.  
a) Re-route the power cables away from the engine.  
b) Add a noise suppressor to the power cable.  
c) Use resistive spark plug wires and/or use an alternator whine filter.  
4. No sound from the external speaker.  
a) Check that the external speaker cable is physically connected.  
b) Check the soldering of the external speaker cable.  
5. Transmissions are always on low power, even when high (Hi) power is selected.  
The antenna may be faulty.  
a) Test the transceiver with a different antenna.  
b) Have the antenna checked out.  
6. Battery symbol is displayed.  
The power supply is too low.  
a) Check the battery voltage. This should be at least 10.5 V 0.5 V DC.  
b) Check the alternator on the vessel.  
7. GPS alarm sounds and LCD shows: Please check GPS link! The NO GPS symbol is  
shown.  
GPS data has been lost. This sequence will repeat every 4 hours until GPS data from an opera-  
tional GPS receiver is available. The GPS cable may faulty or the GPS setting may be incorrect:  
a) Manually enter your position and UTC time data (see Section 3.6.1)  
b) Check that the GPS cable is physically connected.  
c) Check the polarity of the GPS cable.  
d) Check the baud rate setting of the GPS if applicable. The baud rate setting should be  
4800. Parity should be set to NONE.

Appendix E - MMSI and license information  
You must obtain a user MMSI (Marine Mobile Service Identity) and enter it into your Link-8 in  
order to use the DSC functions. Contact the appropriate authorities in your country. If you are  
unsure who to contact, consult your Lowrance dealer.  
The user MMSI is a unique nine digit number, similar to a personal telephone number. It is  
used on marine transceivers that are capable of using DSC (Digital Select Calling).  
Depending upon your location, you may need a radio station license for the Link-8 . You may  
also need an individual operator’s license.
