LICENSE INFORMATION
FCC Radio License
In U.S. waters, vessels which are not required to carry radio equipment are not
required to have an FCC (Federal Communications Commission) ship station license
for a VHF marine radio.
However, any vessel required to carry a marine radio on an international voyage,
carrying a HF single side band radio telephone or marine satellite terminal must have
an FCC license.
License application forms for ship and land stations can be downloaded free from the
FCC web site at this address: www.fcc.gov/formpage.html. You may also order
copies of these forms by calling the FCC Forms Distribution Center at 1-800-418-3676.
Radio Call Sign
At this time, the FCC does not require recreational boaters to have a ship radio station
call sign. The U.S. Coast Guard recommends using the boat's registration number and
state.
MMSI Number Information
The BoatU.S. MMSI Program has been certified by both the Federal Communications
Commission (FCC) and the U.S. Coast Guard to assign MMSI numbers to vessels with
DSC capable radios. To obtain and register your free MMSI number, the Coast Guard
recommends logging onto http://www.boatus.com/mmsi/ and following the

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 navigation receiver. The
following procedures are for sending voice distress messages manually. Sending an
automatic distress call is described in the DSC section 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 or aid to navigation.
4. Explain the nature of your emergency (fire, sinking, collision, grounding, health
condition, injury, etc.).
5. Report the kind of assistance you require (fire, medical aid, pumps, etc.).
6. State the number of people aboard and the condition of any injured.
7. Estimate the seaworthiness and condition of your vessel.
8. Describe your vessel: length, type, color and any distinguishing feature.
9. End the message by saying “Over”. Release the Push To Talk button and listen for
a reply.
10. If there is no reply, repeat the above message procedure. If there is still no
response, try another channel.
6 DSC-900
2.2 Calling Another Vessel
Channel 16 may be used to establish initial contact with another vessel. Ho wever, 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
be repeated 3 times at 2 minute 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 Channel 16 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 listen for 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 and end 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” except in emergencies and radio tests.
• Messages to or from a vessel on land.
• Transmission while on land.
• Obscene, indecent, or profane language.

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 when stowed. Also, consider routing of antenna,
power and NMEA interface cables. Mount the transceiver securely to a solid surface.
3.2 Antenna
Proper installation of a quality VHF antenna is very important to reliable radio
communication. A good quality unity gain a ntenna 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 power buss.
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.
8 DSC-900
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/input settings and connectio ns.

To turn the transceiver Off:
• Rotate the VOL knob CCW until it clicks over the detent to the OFF position.
4.2 Volume and Squelch
The VOLume and SQuelch controls have each knob. They are independent controls
but work together to control audio output from th e speaker. The volume control set
the loudness of sound from the speaker and the squelch control is used to mute
background noise when no received signals are present.
To properly set the VOL and SQ controls:
• Rotate the SQ knob fully CCW.
• Rotate the VOL knob CW until background noise is plainly heard.
DSC-900 11
• Slowly rotate the SQ knob CW until the noise is muted (squelched). Then adjust
the control slightly more CW (approximately 1/8 turn). Use ca re not set to the
SQ control more CW than necessary or weak signals may be heard.
Some channels exhibit more background noise than others, so it may be necessary to
readjust the squelch setting when changing channels or when scanning.
4.3 Keypad
A tone is emitted when any of the 6 k eys are pr esse d. A 3-b eep err or to ne is emitt ed if
the key press is not allowed. Some functions require a holding down of a key. A single
beep is emitted, then after the hold down timeout, a second beep will be heard and the
mode entered. The basic purpose for each key is as follows:
Used for selecting channel and menu.
H/L Use to toggle transmitter power between 25 watts and 1 watt output.
Certain channels are restricted to 1 watt maximum power and will cause the
error beep if the HI/LO key is pressed.
WX Switches to the Wx channel mode. Also toggle Off/On the Wx Alert
function by pressing in Priority or Memory Scan modes.
16/9 Selects the Primary Calling 16/09 or the last channel used. Also cancels DSC

5. DSC OPERATION
The Digital Selective Calling (DSC) functions of your DSC-900 transceiver add
convenience and safety to your VHF communication capability. DSC allows you to
contact other DSC equipped vessels and shore stations by selecting their MMSI from
your directory, choosing a call type, and pressing a key. In an emergency, pressing one
button will send your MMSI and current position to search and rescue (SAR)
authorities and other DSC equipped vessels. Distress calls are covered first. Then,
normal calling procedures are described.
5.1 DSC Monitor
Be sure that the DSC Monitor mode is On (Default setting is On). Since there is no
independent channel 70 receiver, the radio normally monitors channel 70 and checks
other channels on a regular basis to detect a Squelch Break. This control method
assures the radio will acquire the DSC calls possible.
To toggle the DSC Monitor mode On/Off:
• Press and hold the CALL key for about 4 seconds. The DSC MON annunciator
will be On in the display, if channel 70 is being accessed.

To transmit your location automatically during a Distress Call, connection to an
operating GPS navigation receiver is required. Make sure your GPS navigation
receiver is On and operational at all times. GPS data is sent over channel 70 to the
Coast Guard and is the primary starting point of any search and rescue mission. Be
sure the GPS annunciator is On steady and not blinking. If blinking, the GPS data is
not valid.

5.5 Normal DSC Calls
In addition to Distress Call, your DSC-900 can transmit the following types of DSC
calls;
1. All Ship’s Call – sends a Routine DSC Call to any vessel in range of you.
2. Directory Call – sends a Routine Individual Call to any of 10 stored MMSI.
3. New Call – sends a Routine Individual Call by manually entering MMSI of a new
vessel not in the directory.
4. Last Call – sends back a Routine Individual Call to the last incoming DSC call.
Also DSC-900 can transmit the calls of advanced Routine Individual Call; Position
Send, and Position Request. LL position from another vessel can be tra nsferred to th e
DSC equipped chart plotter, if it is connected.
A normal DSC call may be originated from your vessel to another DSC equipped
vessel, or you may reply to a DSC call sent by another vessel. Outgoing calls are made
either by selecting a vessel MMSI from your Directory or by manually entering
(Position Send and Position Request are made from your Directory only).
To access to the above DSC calls:
• Press the CALL key.
• Use the SELECTOR or UP/DOWN keys on MIC to scroll through the four
choices. The LAST always appears first.
