Section 5 - Sending and Receiving DSC Calls  
These DSC facilities are available only on the VHF 710US and VHF 710EU models, and a valid user  
MMSID must have been entered to access the DSC functions.  
5-1 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

Appendix B - Troubleshooting  
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 (2 spare fuses are supplied).  
c) Check the battery voltage. This must be greater than 10.5 V.  
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. No position information is displayed.  
The GPS cable may faulty or the GPS setting may be incorrect.  
a) Check that the GPS cable is physically connected.  
b) Check the polarity of the GPS cable.  
c) Check the baud rate setting of the GPS if applicable. The baud rate setting should be 4800 and parity  
should be set to NONE.

SPECIAL NOTES ON INTERNATIONAL CHANNEL USEAGE  
Notes referring to the Table  
General notes  
The International mode is not legal for use in US or Canada Waters  
a. Administrations may designate frequencies in the inter-ship, port operations and ship movement services  
for use by light aircraft and helicopters to communicate with ships or participating coast stations in pre-  
dominantly maritime support operations under the conditions specified in Nos. 51.69, 51.73, 51.74, 51.75,  
51.76, 51.77 and 51.78. However, the use of the channels which are shared with public correspondence  
shall be subject to prior agreement between interested and affected administrations.  
b. The channels of the present Annex, with the exception of channels 06, 13, 15, 16, 17, 70, 75 and 76, may  
also be used for high-speed data and facsimile transmissions, subject to special arrangement between  
interested and affected administrations.  
c. The channels of the present Annex, but preferably channel 28 and with the exception of channels 06,  
13, 15, 16, 17, 70, 75 and 76, may be used for direct-printing telegraphy and data transmission, subject  
to special arrangement between interested and affected administrations.  
38

Download from Www.Somanuals.com. All Manuals Search And Download.  
d. The frequencies in thisTable may also be used for radiocommunications on inland waterways in accord-  
ance with the conditions specified in No. 5.226. – 56 – 62238 IEC:2003(E)  
e. Administrations having an urgent need to reduce local congestion may apply 12,5 kHz channel interleav-  
ing on a non-interference basis to 25 kHz channels, provided:  
– Recommendation ITU-R M.1084-2 shall be taken into account when changing to 12,5 kHz channels;  
– it shall not affect the 25 kHz channels of the present Annex maritime mobile distress and safety fre-  
quencies, especially the channels 06, 13, 15, 16, 17, and 70, nor the technical characteristics mentioned  
in Recommendation ITU-R M.489-2 for those channels;  
– implementation of 12,5 kHz channel interleaving and consequential national requirements shall be  
subject to prior agreement between the implementing administrations and administrations whose ship  
stations or services may be affected.  
Specific notes  
f.  
The frequency 156,300 MHz (channel 06) (see No. 51.79 and Appendices 13 and 15) may also be used for  
communication between ship stations and aircraft stations engaged in coordinated search and rescue  
operations. Ship stations shall 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.  
g. Channels 15 and 17 may also be used for on-board communications provided the effective radiated  
power does not exceed 1 W, and subject to the national regulations of the administration concerned  
when these channels are used in its territorial waters.  
h. Within the European Maritime Area and in Canada, these frequencies (channels 10, 67, 73) may also  
be used, if so required, 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, under the conditions specified in Nos. 51.69, 51.73, 51.74, 51.75,  
51.76, 51.77 and 51.78.  
i.  
The preferred first three frequencies for the purpose indicated in Note a) are 156,450 MHz (channel  
09),156,625 MHz (channel 72) and 156,675 MHz (channel 73).  
j.  
Channel 70 is to be used exclusively for digital selective calling for distress, safety and calling.  
k. Channel 13 is designated for use on a worldwide basis as a navigation safety communication channel,  
primarily for intership navigation safety communications. It may also be used for the ship movement  
and port operations service subject to the national regulations of the administrations concerned.  
l.  
These channels (AIS 1 and AIS 2) will be used for an automatic ship identification and surveillance system  
capable of providing worldwide operation on high seas, unless other frequencies are designated on a  
regional basis for this purpose.  
m. These channels may be operated as single frequency channels, subject to special arrangement between  
interested or affected administrations. (WRC-2000)  
n. The use of these channels (75 and 76) should be restricted to navigation-related communications only  
and all precautions should be taken to avoid harmful interference to channel 16, e.g. by limiting the  
output power to 1 W or by means of geographical separation.  
o. These channels may be used to provide bands for initial testing and the possible future introduction  
of new technologies, subject to special arrangement between interested or affected administrations.  
Stations using these channels or bands for the testing and the possible future introduction of new  
technologies shall not cause harmful interference to, and shall not claim protection from, other stations  
operating in accordance with Article 5. (WRC-2000)

Installation Options  
There are two ways to install the radio. You can choose:  
a deck or overhead mounted gimbal installation. The reversible mounting gimbal is fixed to to a suitable  
site and the radio is placed into it. The radio can be removed for storage and the viewing angle can be  
adjusted.  
a recessed installation. The radio is recessed into a cavity cut into a bulkhead. The radio fixture is perma-  
nent and the viewing angle cannot be adjusted.  
Location Requirements - Please check these before doing any cutting or drilling.  
Whichever installation method you choose, ensure that the chosen location:  
is at least one metre (3') from the antenna  
allows easy connection to (at least) a 10 Amp fused 13.6V DC electrical source and the antenna  
is at least 45cms (1.5') from the compass to avoid creating magnetic deviation of the compass during  
radio operation  
has a suitable space close by for installing the microphone bulkhead mount  
provides easy access to the front panel controls  
provides reasonable access to the wiring at the back of the radio  
provides enough room to fix the DSC warning label (710US and 720US).  
52

Download from Www.Somanuals.com. All Manuals Search And Download.  
Gimbal Installation  
1. Hold the mounting gimbal at the chosen location and use a soft pencil to mark the screw hole positions  
onto the mounting surface.  
2. If you cannot reach behind the mounting surface to attach the nuts, use the 5mm self-tapping screws  
instead of the flat screws shown in the picture. If you are drilling into fiberglass, use a drill bit smaller  
than 5mm to drill the pilot holes.  
Otherwise, drill the four screw holes where marked, using a 5mm (3/16”) drill bit. Drill completely through  
the mounting surface.  
3. Use a Philips screwdriver and the set of four flat screws, spring washers, plain washers, and nuts to attach  
the mounting gimbal to the location site.  
4. Slide the radio into the mounting gimbal.  
5. Insert the two mounting knobs through the holes and tighten them sufficiently to hold the radio at the  
desired viewing angle.

Changing the Viewing Angle  
The viewing angle has a 20º tilt range. To change the current viewing angle on a gimbal mount:  
1. Support the radio then loosen the mounting knobs until the radio can be moved.  
2. Re-position the radio then tighten the mounting knobs again.  
Recessed Installation (picture below)  
1. Tape the installation template onto the chosen location site.  
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. Remove the installation template and slide the radio into the cavity.  
4. Working from the rear of the bulkhead, align the racheted outstand on each side of the radio with the  
central hole in each mounting bracket.  
5. Use the two short M5x10 screws to screw the mounting brackets to the sides of the radio.  
6. Slide each M5x32 screw through the screw hole in the mounting bracket, then attach the lock nut and  
the stopper. If your bulkhead exceeds 13mm, the stopper nut can be discarded if necessary.  
7. Tighten the M5x32 screws until the radio is held against the rear of the bulkhead.  
8. Tighten up the lock nuts to secure the installation.  
Connecting the Radio  
There are three sockets at the rear of the radio, as shown. The combined power & speaker socket and the  
GPS socket have short connectors already in place but further electrical wiring is required at the rear of the  
radio.
