2. BASIC RADIO COMMUNICATION PROCEDURES
Distress or emergency calls may be made either manually or automatically. Sending
distress calls automatically uses the Digital Selective Calling (DSC) functions of your
transceiver and requires as operating and properly connected navigationreceiver. The
following procedures are for sending voice distress messages manually. Sending an
automatic distress callis described in the DSCsection of this manual.
2.1 Using Channel 16
Channel 16 is the Calling and Distress channel. An emergency may be defined as a
situation that threatens human life or property. In such situations, make sure your
transceiver is turned On and set the channel selector to Channel 16. Then use the
following procedure to make a distress call. The total transmission should not exceed 1
minute.
1. Press the microphone Push To Talk button. Speak slowly and clearly into the
microphone: “Mayday, Mayday, Mayday, this is [your vessel’s name], [your
vessel’s name], [your vessel’s name]”.
2. Then repeat once: “Mayday,[your vessel’s name]”.
3. Continue by reporting your position in latitude and longitude or by reporting
your bearing (true or magnetic, specify which) and distance from a prominent or
well known landmark, geographic feature oraid to navigation.
4. Explain the nature of your emergency (fire, sinking, collision, grounding, health
condition, injury, etc.).
5. Report the kind of assistance yourequire (fire, medical aid,pumps, etc.).
6. State the number of people aboard and the conditionof any injured.
7. Estimate the seaworthiness and condition of your vessel.
8. Describe yourvessel: length, type, color and any distinguishing feature.
9. End the message by saying “Over”. Release the Push To Talk button and listen for
areply.
10. If there is no reply, repeat the above message procedure. If there is still no
response, try another channel.

DSC-900 7
2.2 Calling Another Vessel
Channel 16 may be used to establish initial contact with another vessel. However, its
most important use is for voice emergency messages. Channel 16 must be monitored
at all times except when engaged in actual communication on another channel.
Channel 16 is monitored by international search and rescue (SAR) authorities,
National Coast Guards and by other vessels. Use of Channel 16 for calling or hailing
must be limited to initial contact only. Calling should not exceed 30 seconds and may
berepeated 3 timesat 2minute intervals.
Prior to making contact with another vessel, determine which channel will be used for
continued communication after the initial contact. Monitor the desired channel for
traffic and, when clear, switch to Channel16 to make initial contact.
Listen for traffic on the Calling Channel (16). If clear, press the Push To Talk (PTT)
button on the microphone. Speak the name of the vessel you are calling followed by
“this is” and the name of your vessel and your call sign. Release the PTT and listen for
a reply. When the other vessel returns your call, acknowledge the call with “go to”, the
number of the new channel and “over”. Switch to the new channel and listenfor traffic.
If necessary, wait for traffic to clear, and then call the other vessel. As communication
proceeds, end each transmission with “over”. When communication with the other
vessel is completed, end the last transmission with your call sign and the word “out”.
It is not necessary to end each transmission with your call sign, just give your call sign
at the beginning andend of each contact.
Remember to switch to Channel 16 when not actively communicating on another
channel.
2.3 Prohibited Communication
The following communications are prohibited by regulations and violators are subject
to penalties.
•False distress or emergency messages(including false DSC distress).
•Messages to “any vessel” exceptin emergencies and radio tests.
•Messagesto or froma vessel on land.
•Transmissionwhile on land.
•Obscene,indecent, or profanelanguage.

3.INSTALLATION
3.1 Transceiver
Your DSC-900 transceiver is designed to withstand the rigors of the marine
environment. However, selecting a mounting location affording some protection from
the elements will prolong the life of connectors, controls and the liquid crystal display
(LCD).
Select a location within easy reach and view of the operator and away from your
vessel’s compass. Locate the microphone to avoid entanglement with steering or
engine controls, both when in use and whenstowed. Also, consider routing of antenna,
power and NMEA interfacecables. Mount the transceiver securely to asolid surface.
3.2 Antenna
Proper installation of a quality VHF antenna is very important to reliable radio
communication. A good quality unity gain antenna is recommended for maximum
range performance. In general, antennas should be located as high as practical and
separated as much as possible from other antennas and structures. The minimum
distance to other objects is 1 meter. Route the antenna cable away from other electronic
equipment and do not bundle the antenna or power cable with other wiring,
especially transducer cables for depth sounders and fish finders. For cables longer than
10 meters, RG-8/U coaxial cable must be used. Mount the antenna and install the
connector(s) in accordance with manufactures instructions. Connect the antenna cable
to the RF output connector on the rear panel of the transceiver.
3.3 Power Connection
CAUTION
Reverse polarity connections can damage your transceiver
The power cable for your transceiver must be connected to the ship’s main powerbuss.
Connect the Red wire to the positive (+) terminal and the Black wire to the negative (-)
terminal. Connect the barrel terminals on the power cable to the matching color wires
and terminals extending from the rear panel of the transceiver.

DSC-900 9
3.4 Rear Panel Cables
The white and black cables on the rear panel are provided for connecting an external
speaker. Use an 8 Ohm speaker rated for at least 3 Watts and suitable for the
environment at the chosen location.
Other cables are provided for connecting an operating GPS navigation receiver, in
order for the position reporting/transferring features of your transceiver to function.
Refer to your GPS navigation receiver manual for information about its NMEA
output/inputsettings andconnections.
