RADIO LICENCES
Ship Station License
When your craft is equipped with a VHF FM radio, you must have a current radio station licence before using the radio. It is unlawful to operate a ship station which is not licensed. Inquire through your dealer or the appropriate government agency for a Ship-Radiotelephone license. This license includes the call sign which is your craft’s identification for radio purposes.
Operators License
A restricted Radiotelephone Operator Permit is the license most often held by small vessel radio operators when a radio is not required for safety purposes. The restricted Radiotelephone Operator Permit must be posted near the radio or be kept with the operator.
Only a licensed radio operator may operate a radio. However, non-licensed individuals may talk over a radio if a licensed operator starts, supervises, ends the call and makes the necessary log entries.
A current copy of the applicable government rules and regulations is only required to be on hand for vessels in which a radio telephone is compulsory. However, even if you are not required to have these on hand it is your responsibility to be thoroughly acquainted with all pertinent rules and regulations.

OPERATING RULES
Priorities · Read all rules and regulations pertaining to priorities and
keep an up-to-date copy handy. Safety and distress calls take priority over all others.
· You must monitor Channel 16 when you are not operating on another channel.
· False or fraudulent distress calls are prohibited under law. Privacy · Information overheard but not intended for you cannot
lawfully be used in any way.
· Indecent or profane language is prohibited.

RANGE
The range of VHF transmissions depends on antenna height, transmitter power and the terrain over which the signals pass. For a 5 watt handheld radio like the TX850, ship to ship communications up to 5 nautical miles should be possible. Using an external antenna should allow ship to ship communication of 8 nautical miles or more. Ship to shore ranges will often be greater due to the increased height of the shore antenna.

MARINE MOBILE SERVICE IDENTITY (MMSI)
The MMSI is a 9-digit number used to identify a radio that is capable of using Digital Selective Calling (DSC). The number is used to selectively call other vessels. To setup and use the DSC feature on your radio: Please refer to the DSC’ section of this manual. USER MMSI To use the DSC feature you must be registered with the appropriate licensing authority (AMSA in Australia) who will issue you with your unique user MMSI number. Having a registered user MMSI means you can be identified much quicker in an emergency. Once you have obtained your MMSI number you can then enter this into your GX850 to enable DSC operation. Your GX850 is shipped from the factory without a user MMSI number. It is up to the user to obtain a valid MMSI from the appropriate licensing authority. NOTE: If you don’t register for a User MMSI, you can still receive DSC distress calls from other vessels however you cannot send a DSC call. GROUP MMSI The Group MMSI is used for DSC Group Calls. A Group Call provides a method for contacting a group of vessels with a common interest, for example, alerting all yachts in a race to announce a change in the race conditions. Any number with a leading zero can be used as a Group MMSI, and they do not need to be registered, but the entity deciding on a Group MMSI must use the MID of the host country or country of vessel registration (e.g. 503 in Australia). The Group ID should be based on a key vessel in the Group, and the recommended system is to drop the last digit of the key vessel’s MMSI and place a zero in front. For example, a fleet of vessels that has a lead vessel with a DSC User MMSI of 503080110 could use the Group MMSI of 050308011. This would then be programmed into all fleet vessels as the special event Group MMSI. SeeMy MMSI ID Setup’ on page 13 for details on entering a group MMSI.

When the GX850 is not receiving GPS signals, the screen will display the time and date.

To switch the time and date display on or off, press and hold the SQL key for 3 seconds.

DISPLAYING LOCAL TIME

GPS time is received from the satellites in UTC format. To display the time as local time please refer to the GPS Setup option on page 19.

DIGITAL SELECTIVE CALLING

The Digital Selective Calling (DSC) feature on your GX850 uses preformatted digital data messages instead of voice to transmit urgent or important information to another radio. In times of an emergency, DSC can alert all radios within range

to a distress message even when a listening watch is not being maintained. This increases the chances of your signal being heard. DSC can also be used to make All Ships Calls, Group Calls and Position Requests as well as routine calls to individual radios.
DSC is part of the Global Maritime Distress and Safety System (GMDSS) which is expected to eventually replace listening watches on distress frequencies and will be used to announce all routine and urgent maritime safety information broadcasts.
DSC AND GPS
DSC operation is enhanced by the in-built GPS receiver in your GX850. By using GPS, your distress call can automatically include your current position and time. If a GPS position cannot be obtained, DSC calls can still be sent and received to alert the operator of another vessel for subsequent voice communication.
DSC calls are automatically sent and received on CH70. The GX850 has two receivers, one of which is dedicated to CH70. Therefore, regardless of which channel you are operating on, the GX850 will not miss a DSC call.
USER MMSI (MARINE MOBILE SERVICE IDENTITY)
A User MMSI is a unique 9-digit number used to identify a DSC capable radio. An MMSI is used to selectively call other vessels. Before you can use DSC, you must enter your User MMSI number into the My MMSI ID’ option in the DSC Menu. If you don’t yet have a User MMSI, please register with your local Maritime Authority (AMSA in Australia – go to http://www.amsa.gov.au/mmsi/ for more details and to download an application form) who will then issue a unique MMSI number. Please refer to theMy MMSI ID’ option further below for instructions on entering your User MMSI.
DISTRESS CALLS
To make a Distress Call use the button under the Red DISTRESS cover on the side of the GX850. To make any other DSC call, use the key on the main keypad.

MY MMSI ID SETUP

Before using the DSC function you must set up your user MMSI ID. If you don’t yet have a User MMSI, please register with your local Maritime Authority.

NOTE: The reception of distress calls does not require a user MMSI.

IMPORTANT: It is a requirement of the regulations that the User MMSI can only be entered ONCE. For this reason take special care when entering your user MMSI number to ensure it is entered correctly before saving it. You will be required to enter your MMSI twice as confirmation of the correct number before it is stored by the radio. If you need to change the MMSI (due to an entry error or after purchasing a second hand GX850) please contact GME to arrange for the MMSI code to be reset.

INDIVIDUAL CALL, POSITION REQUEST, GROUP CALL AND TEST CALL
The Individual Call’ option is used to alert a specific vessel that you wish to communicate with them on a specified channel. If the called vessel’s radio is on a different channel, their radio will change to the channel you specify. APosition Request’ (or position polling) is used to obtain the position of another vessel. If the receiving vessel is in range, an acknowledgement will be received from them that will include their position. If there is no acknowledgement, either the receiving boat is not in your communication area or it has chosen to ignore your request.
A `Group Call’ is used to contact a group of vessels that are using the same Group MMSI. All ships in the group who receive the Group call will change to the specified channel. For example, this feature could be used to alert all yachts in a race to announce a change in the race conditions. Any number with a leading zero can be used as a Group MMSI, and they do not need to be registered, but the entity deciding

on a Group MMSI must use the MID of the host country or country of vessel registration (503 in Australia). The Group ID should be based on a key vessel in the Group, and the recommended system is to drop the last digit of the key vessel’s MMSI and place a zero in front. e.g. a fleet of vessels that has a lead vessel with a DSC self-ID of 503080110 could use the Group MMSI of 050308011. This would then be programmed into all fleet vessels as the special event Group MMSI.
The Test Call’ option can be used to make a test call to your local Coast Station. The coast station should provide an automated response to confirm that your radio’s DSC is operating correctly. The operations of the call options described above are very similar. 1\. Briefly press the key to enter the DSC menu. 2\.

ALL SHIPS CALL

An All Ships Call allows your radio to establish contact with all the other ships in your area without needing to enter their MMSI. All Ships calls are classified as ROUTINE, SAFETY or URGENCY. URGENCY calls (similar to a PAN PAN call) may be sent when a vessel is not in immediate distress but has a problem that may lead to a distress situation. SAFETY calls (similar to SECURITY calls) may be sent when safety information needs to be transmitted to other vessels.

To send an All Ships Call;

DSC Setup Position Input Auto Ch Change Position Reply Test Ack

Position Input The Position Input allows you to manually enter a position in Latitude and Longitude and a time in UTC.
Auto Channel Change The Auto Channel Change option will determine whether your radio will change channels automatically when requested by another radio. Generally this should be set to Automatic as the DSC system is designed to guide to you a specific channel after receiving a DSC call. However there may be times when this is not desirable, in which case set this feature to Manual.
Position Reply Position Reply determines whether your radio will respond automatically to a `Position Request’. If set to Automatic, your radio will automatically respond to a Position Request by transmitting your location back to the caller.
If you do not wish to allow other radios to request your position, set this option to Manual.
Test Acknowledge Test Acknowledge determines if your radio will respond automatically to a Test call. Test calls sent to a coast station or to another ship can be used to check if the DSC function on your radio is working correctly. If set to Automatic, a Test call sent to your User MMSI will cause your radio to automatically respond to the caller allowing them to confirm their radio is operating correctly.
To disable the Test Acknowledge feature, set this to Manual.

ATIS OPERATION
ATIS stands for Automatic Transmitter Identification System and is generally used in the inland waterways of Europe. ATIS is used to identify a ship or vessel that has made a radio transmission. The identity of the vessel is sent digitally immediately after the ship’s radio operator ceases talking and releases their radio’s PTT switch. The ATIS system is similar to the DSC system except that DSC transmissions take place exclusively on Channel 70 whereas the ATIS digital signal is transmitted on the same VHF channel as the voice transmission.

Intership channels are for communications between ship stations. Intership communications should be restricted to Channels 6, 8, 72 and 77. If these are not available, the other channels marked for Intership may be used. Channel 70 is used exclusively for Digital Selective Calling (DSC) and is not available for regular voice communications.
NOTES
1. Channel 06 may also be used for communications between ship stations and aircraft engaged in coordinated search and rescue operations. Ship stations should avoid harmful interference to such communications on channel 06 as well as to communications between aircraft stations, ice breakers and assisted ships during ice seasons.
2. Within the European Maritime Area and in Canada, channels 10, 67 and 73 may also be used by the individual administrations

concerned for communication between ship stations, aircraft stations and participating land stations engaged in coordinated search and rescue and anti- pollution operations in local areas. Channels 10 or 73 (depending on location) are also used for the broadcast of Marine Safety Information by the Maritime and Coast Guard Agency in the UK only.
3. Channel 13 is designated for use on a worldwide basis as a navigation safety communication channel, primarily for intership navigation safety communications.
4. Channels 15 and 17 may also be used for on-board communications provided the effective radiated power does not exceed 1 watt.
5. The use of Channels 75 and 76 should be restricted to navigation related communication only and all precautions should be taken to avoid harmful interference to channel 16. Transmit power is limited to 1 watt.

A channels are generally only used in the United States, and use is normally not recognized or allowed outside the U.S. The letter B indicates simplex use of the coast station transmit side of an international duplex channel. The U.S. does not currently use B channels for simplex communications in this band.
Boaters should normally use channels listed as NonCommercial. Channel 16 is used for calling other stations or for distress alerting. Channel 13 should be used to contact a ship when there is danger of collision. All ships of length 20m or greater are required to guard VHF channel 13, in addition to VHF channel 16, when operating within U.S. territorial waters. Users may be fined by the FCC for improper use of these channels.

Channel numbers, e.g. (WX1, WX2) etc. have no special significance but are often designated this way in consumer equipment. Other channel numbering schemes are also prevalent.
The order of channels shown is the order they were established and is slowly becoming less popular over time than a numerical ordering of channels.
See NATIONAL WEATHER SERVICE MARINE PRODUCTS VIA NOAA WEATHER RADIO and the NOAA Weather Radio Homepage for more information.
