Display This menu allows the user to partially customize the screen information displayed, and adjust the screen for best visibility to suit the user and operating conditions. Time display Select to switch the display of Time to ON or OFF. If turned ON, the display of COG/SOG is turned off, due to screen space constraints. LOC (Local Time) is displayed below the time if a UTC (Coordinated Universal Time) offset has been entered; otherwise UTC is shown in it’s place if no offset has been applied.
Radio setup The Radio setup menu covers settings that are typically configured at installation, and seldom need changing. Local/Dist Use LOCAL/DIST to improve the sensitivity of the receiver either locally (LOCAL) or over distances (DIST). LOCAL is not recommended for use in open sea conditions. It is designed for use in areas of high radio noise; for example, close to a busy port or city. UIC Select between USA, International or Canadian channel banks.
Select COURSE to toggle between displaying in MAGNETIC or TRUE. A true north heading is corrected for magnetic declination. A magnetic north heading source must also output magnetic variation data if the heading is to be displayed as a true north value. Int speaker Select to switch the radio’s internal speaker ON or OFF. Incoming voice calls and audible DSC alerts are prevented, but key beeps and alarms will still be audible. Ext speaker Select to switch the radio’s external speaker ON or OFF.
GPS SIM Select to toggle ON or OFF. Whenever the GPS Simulator is turned ON, simulated Speed Over Ground (SOG), Course Over Ground (COG), and LL position appear on the screen. This is for the purpose of demonstration only. The SIM icon is displayed to warn the user it is in this mode. ¼¼ Note: It is not possible to send a DSC transmission when in Simulator mode. ¼¼ Note: The GPS Simulator is set to OFF whenever the radio has the power cycled, or real GPS data is available through the COM port.
User MMSI Enter an MMSI number to access the radio’s DSC functionality. This unique identifier must be supplied a local radio spectrum authority. DO NOT enter a random ‘made up’ number. ¼¼ Note: Contact a Simrad dealer if you need to change your MMSI after initial input. ATIS function (EU ATIS radios only) ATIS must be enabled when navigating inland waterways in signatory countries of the RAINWAT agreement. It should NOT be used outside these regions.
Position request acknowledge (“POS ACK”) The radio can be configured to automatically acknowledge an incoming position request, require manual intervention to acknowledge, or simply ignore them: AUTO Sends current position automatically to calling radio. MANUAL Operator must manually choose to send position information. OFF All incoming position requests are ignored. Auto channel switch (“AUTO SWITCH”) This setting only relates to All Ships and Group DSC calls.
DSC timeout An inactivity timeout can be set up to return the radio to normal operational mode when no activity is seen from the radio operator while radio is engaged in a DSC call. Distress calls have a discrete timer from that used for all other DSC calls: Distress Select between NONE, 5 MINS, 10 MINS and 15 MINS. (default is NO TIMEOUT). Non Distress Select between NONE, 5 MINS, 10 MINS and 15 MINS. (default is 15 MINS).
Alert volume Select between HIGH, LOW, and OFF. Screen flash Select between ON and OFF. DSC Alarm The alert volume and screen flash for some incoming call types can be altered. SAFETY, ROUTINE and URGENCY calls can individually be set to have: Alert volume HIGH, LOW or OFF. Screen flash ON or OFF.
3 DSC call menu DSC (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.
The Distress Call is automatically re-sent every 3.5 to 4.5 minutes until a distress acknowledgement is received.
All ships Used to place a call to ALL DSC equiped vessels in range, much like a distress call. The nature of the call must be selected, and can be either SAFETY or URGENCY. When the SEND TO page is displayed, turn the channel knob to select the channel to use for voice communication. Call logs Shows a record of SENT, RECEIVED, and DISTRESS calls. POS request Used to send a postion request to another vessel.
Select buddy Shows any existing ‘buddies’ already selected, and the option to add more. Selecting a ‘buddy’ already in the buddy list will remove them. Choose ADD/UPDATE BUDDY to view the full contacts list, and choose who to add for tracking. Start tracking / Stop tracking Selecting START TRACKING option initiates tracking of buddies in the Track buddy list that have been set to tracking ON. The radio will show a screen indicating which buddy is being called.
View/Add Contact Use this to store the names and associated MMSI’s of up to 50 vessels to be called regularly using DSC. Contacts are stored by name, in alphabetical order. Select ADD NEW to create a new contact. Selecting an existing name in the Contacts list gives the options to place a DSC call, make a position request, edit the contact, or delete the contact. View/Add Group Use this to create, edit, or delete up to 20 vessel groups, which are stored in alphanumeric order.
4 My channels The MY CHANNELS page is accessed by a long press of the channel knob. This page provides a shortcut to frequently accessed channels. The first time this page is opened, the entire channel list is shown so that the desired shortcut channels can be selected. Subsequent opening of this page will show a list of only the selected channels. Choosing one of the channel options immediately exits the page and sets the radio to that channel.
5 Shortcuts The Shortcuts page is accessed by a long press of the VOL/SQL knob. This page is provided as a shortcut to frequently accessed settings. The shortcut options available on this page are subject to selections made in ADD/EDIT SHORTCUTS. Add/Edit shortcuts Choose from the list of options which menu options should be added as shourtcuts; ¼¼ Note: The MY VHF page is only available to the operator when enabled as a shortcut - it can’t be accessed via another menu.
6 Installation This Simrad DSC VHF radio is designed to generate a digital maritime distress call to facilitate search and rescue. To be effective as a safety device, this radio must be used only within the geographic range of a shore-based VHF marine Channel 70 distress and safety watch system. The geographic range may vary but under normal conditions is approximately 20 nautical miles. Checklist The following items should be supplied in the box.
Installation options • • There are two mounting options for the radio: Bracket mount: Using the supplied gimballing bracket the radio can be mounted to either sit on top of, or hang underneath any flat horizontal surface. The radio can be removed for storage and the viewing angle can be adjusted. Flush mount: The radio is recessed into a cavity, showing only the face of the radio. The radio fixture is permanent and the viewing angle cannot be adjusted.
Bracket installation The gimbal bracket provides an adjustable viewing angle with a 20º tilt range, so ensure the selected mounting location will provide the desired viewing and operating conditions: 1. Hold the bracket at the chosen location and use a soft pencil to mark the screw hole positions onto the mounting surface. 2. Use a 3mm (1/8” ) drill bit to drill the 4 pilot holes. 3. Using a Philips screwdriver, secure the bracket using the supplied 4x25mm self-tapping screws to the mounting location. 4.
Flush installation 1. Tape the installation template onto the chosen mounting location. 2. Cut out the area marked by the solid dark line (the dashed line indicates the total area that will be covered by the radio fascia after installation). 3. Use a 2.5mm (3/32” ) drill bit to drill the 4 pilot holes. 4. Remove the installation template. 5. Fit the gasket to the radio. 6. Slide the radio into the cavity. 7. Using a Philips screwdriver, secure the radio using the supplied 3.
Connect the radio wiring All wiring on the radio should be done with the vessel power supply turned off. While radio power is polarity protected, the fuse will blow if connection is made wrong way round. Ensure any unused bare wires are isolated from each other, to prevent the potential of a short circuit. If using the NMEA 2000 connection, ensure network topology rules are followed closely. ! Warning: never operate the radio without the antenna connected. This may damage the transmitter.
antenna 6. NMEA 0183 TX_A (white): connect to RX_A of chart plotter 7. NMEA 0183 TX_B (brown): connect to RX_B of chart plotter 8. GND: optional ground connection. May help with induced noise issues. 9. Antenna: connect to a marine VHF antenna using 50 ohm cable fitted with a PL-259 connector 10. Battery + (red): connect to vessel’s 12 V DC, via a switch panel or breaker (comes with inline 8 amp fuse ready fitted) 11.
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. Set the time offset for your region. Choose whether to display time in 12 or 24 hour. MMSI and ATIS ID • • • • • • 38 | The 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.
• If you need to have the MMSI in the radio changed, the radio must be taken back to your Simrad dealer. ATIS Automatic 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.
