FCC Radio License and MMSI Number Information
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.
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.
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 instructions.
iii
FCC Digital Device Compliance
This device complies with Part 15 of the U.S. Federal Communications Commission (FCC) Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment.
Note:
This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
•Consult the factory customer service department for help.

FCC Radio Frequency
Compliance Requirements and Warnings
When operating your marine radio transceiver, you should know that
the antenna radiates radio frequency (RF) energy. This radio was designed to meet the FCC’s rules and regulations for the maximum permissible exposure to radio frequency energy. This design was tested
and found to be compliant with the strict requirements established by
the FCC.
DO NOT operate the radio without a proper antenna attached, because
this may damage the radio and may also cause you to exceed FCC RF
exposure limits. Antenna types suited for this radio are described in
the installation section.
DO NOT transmit for more than 50% of the total radio use time.
Transmitting more than 50% of the time can cause FCC RF exposure
compliance requirements to be exceeded. The radio is transmitting
when the “TX indicator” is displayed on the screen. You can cause the
radio to transmit by pressing the "PTT" (Push To Talk) switch.
IMPORTANT: The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 91 cm (37 inches)
from all persons (including passengers). The antenna(s) must not exceed an antenna gain of 3 decibels (dB) and must not be co-located or
operating in conjunction with any other antenna or transmitter.
Section 1: Installation
Introduction
Thank you for purchasing the M-Tech MT-300 DSC VHF Radio. We
know you’re anxious to try it out, but first, let us explain how this manual can help you get the most out of your new radio.
We have designed this book so you don’t have to read the whole thing
from front to back to find the information you want. At the start of each
segment, we’ll tell you what content is coming up next. If it’s a concept
you're already familiar with, we’ll show you where to find the next important topic.
We lead off the manual with proper Distress Call procedures on page 4.
We put it at the front of the book to make it easy to find in case of an
emergency.
The first section covers MT-300 installation and specifications.
The second section, Basic Radio Operation, goes over some basic functions of the radio and includes instructions on how to set up your MMSI
(Maritime Mobile Service Identity) number. You can't make a call
without it! To jump to MMSI setup, flip to page 8. To acquire a free
MMSI number, see the web address on the bottom of page ii.
The third section, Advanced Radio Operation, offers more detailed information about the radio's features. The section will touch on all aspects of the radio's functionality, providing clear and complete explanations via a convenient alphabetical layout.
Let’s get started!
Powering Your Radio
(Power Supply cable – red and black wires)
The unit works from a 12-volt electrical system. You may attach the
radio to a 12-volt battery or to an auxiliary power panel.
If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
noise. The power cable has two wires, red and black. Red is the positive
lead, black is negative or ground. Make sure to attach the in-line fuse
holder to the red lead as close to the power source as possible.
Auxiliary Wires
The white and black auxiliary wires on the back of the unit connect
your radio to an external speaker. Connect the white (+) wire to the
speaker's positive lead, and connect the black (–) wire to the speaker's
negative lead.
The remaining auxiliary wires are used for DSC (Digital Selective Calling) service, where the radio can exchange latitude and longitude position information with a GPS (Global Positioning System) receiver in
NMEA 0183 format.

Caution
All of the auxiliary wires have bare ends for easier installation.
The bare ends on any unused wires could cause an electrical
short if left exposed. To prevent this, you should cover the individual wire ends – either by capping them with wire nuts or
wrapping them with electrical tape.
Bracket Installation
Mount the unit in any convenient location, provided there is clearance
behind the unit when it's tilted for the best viewing angle. You should
also make sure there is enough room behind the unit to attach the
power, antenna and auxiliary cables. Pick a location far enough from
any compass to avoid compass deviation caused by the speaker magnet.
The radio must be installed at least three feet from the antenna. Make
sure there is space nearby to hang the mic clip.
Holes in the gimbal bracket's base allow wood screw or through-bolt
mounting. You may need to place a piece of plywood on the back side of
thin fiberglass panels to reinforce the panel and secure the mounting
hardware. We suggest that you use stainless steel screws for installation.
Screw

hole
Front
Install the gimbal bracket, which looks similar to the one pictured here. Place
the bracket so the arms slope toward the radio's front.
Once a location is determined, use the bracket as a template and mark
the mounting holes. Screw the bracket to the mounting surface. Be sure
to leave enough slack in the cables to allow tilting the unit.
Attach the unit to the gimbal bracket using the supplied gimbal knobs
and washers. Attach the cables and the unit is ready to use.
Antenna
A good antenna installation will optimize the performance of your marine radio. There is no height requirement for antenna installation, but
the higher it is mounted, the better the reception. That's because marine VHF radio signals travel only on a "line of sight" basis. An ideal
installation will give the antenna a clear view of the horizon in all directions.
The antenna may be mounted on a gunwale, rail or on flat surfaces like
a deck, roof or bulkhead. In the case of some sailboats and powerboats,
it may be attached to a mast or mast-like structure.
When installing your VHF marine antenna, be sure to keep it at least
three feet away from any other antenna or metal object. The antenna
also must be installed three feet away from the radio, and at least three
feet from any passengers or crew. Refer to the antenna manufacturer's
instructions for further installation information. You must also make
sure your antenna and its installation complies with all local and federal regulations. Never operate your radio unless it is connected to the
antenna.
The antenna must not exceed an antenna gain of 3 decibels (dB). The
antenna cable requires a PL259 connector, and the cable connects at
the back of the radio. For installations less than 25 feet, use RG58 coaxial cable. For installations greater than 25 feet, use RG-8/U coaxial
cable.
WARNINGS:
Using an antenna with gain greater then 3 dB can damage the
radio and exceed the safe exposure limits for radio frequency
(RF) energy.
Also, the energy from any VHF radio antenna can be harmful,
even one properly rated at 3 dB of gain! Do not come in contact
with the antenna while a transmission is being sent. Be sure
the antenna is installed where it is separated from people by
at least 3 feet of space.
How to Make a Distress Call
Speak slowly, clearly and calmly.
1. Select VHF Channel 16.
2. Press microphone button: "MAYDAY — MAYDAY— MAYDAY."
3. "THIS IS [your ship ID]."
4. "MAYDAY [your ship name]."
5. Tell where you are — what navigational aids or landmarks are near.
6. State the nature of your distress.
7. Give number of persons aboard and condition of any injured.
8. Estimate present seaworthiness of your ship.
9. Briefly describe your ship — meters, type, color, hull.
10. "I WILL BE LISTENING ON CHANNEL 16."
11. End message by saying "THIS IS [ship name/call sign] OVER."
12. Release the PTT key and listen. Someone should answer. If not, repeat call, beginning at Item 3 above.
WARNING
The following types of communication are prohibited by the
FCC: false distress calls; calls to any boat — excluding emergencies and radio tests; calls to or from a vessel on land and
obscene or profane language. Using obscene or profane language could result in a fine of up to $10,000.
Section 2: Basic Radio Operation
This section addresses the radio’s basic operations, which includes
MMSI (Maritime Mobile Service Identity) number setup. If you already
have your MMSI number programmed into the radio and have a strong
understanding of the radio's basic functions, move on to Section 3: Advanced Radio Operation.
The M-Tech MT-300 VHF Marine Radio.
We're going to kick off the operation section with a brief description of
the radio's basic functions. That will be followed by some important
information on Digital Selective Calling and basic instructions on how
to make and receive calls.
Using the Keypad
The keypad has six keys: H/L (Hi/Lo), WX (Weather), 16/9 (Priority
Channels), SCN (Scan), MEM (Memory), CALL (Call). When you press
any of the keys a tone will sound. If you push a key and a 3-beep tone
sounds, there is an error or the function is not supported by the radio.
You’ll notice several functions require you to hold down a key for a few
seconds. In those cases, a single beep sounds, then, after a few moments, a second beep will be heard to let you know you have successfully changed the mode.
Power/Volume
The volume knob at the top right of the radio’s face is used to power up
the MT-300. Turn the knob clockwise to turn on the radio. The unit will
start on Ch. 2, then switch to Ch. 16, its default priority channel.
Squelch
Squelch, the bottom knob on the radio’s face, helps the unit screen out
radio traffic resulting from signals that are too weak to transmit anything but noise. To adjust the squelch, turn it to the left until noise can
be heard. Turn it back to the right until the noise is eliminated.

H/L (High/Low)
The H/L key gives you control over the radio's wattage. The high-end is
25 Watts. The low-end is 1 Watt. If the LO ANNUNCIATOR is off, the radio
will transmit at 25 Watts.
WX (Weather)
Dark clouds on the horizon? Press the WX key to enter the WX (WEATHER)
MODE and get the latest weather information. Use the Selector to
change the WX channel.
16/9 (Priority Channel)
The 16/9 key is used to switch between priority channels. It also allows
you to exit various operation modes, ignore incoming calls and cancel
outgoing calls.
NOTE
Ch. 16 and Ch. 9 may only be used to make initial contact with a
vessel and nothing more. When there is an emergency, all Distress
calls will be broadcast on Ch. 16.
SCN (Scan)
The SCN (scan) key allows you to monitor numerous channels at the
same time. Scanning options include: PRIORITY SCAN, MEMORY SCAN AND
ALLSCAN.
MEM (Memory)
The MEM key may be used to initiate a Memory Scan and gives you the
option of adding or deleting channels from the radio's scan list memory.
CALL
By pressing the CALL key you can make a new call, return the last incoming call, place a call to all ships or to one of up to 10 stored MMSI
numbers from a saved directory.
DISTRESS
By lifting up the red cover and holding down the DISTRESS button for
three seconds, you will send a distress call to the Coast Guard and any
other ship within range of you.
Selector
Use the Selector to scroll through the channels and various menu options.
PTT (Press to Talk)
The PTT key is the talk button on the microphone. Press and hold it
down to talk when making or receiving a call.
DSC Calling vs. non-DSC Calling
The MT-300 supports two types of calls, Digital Selective Calls (DSC)
and non-Digital Selective Calls. A non-DSC call is the traditional
method where an individual hails another vessel on Ch. 16, then asks
the other party to switch to a working channel set aside for the desired
communication type. Once they have left Ch. 16 and the selected working channel is clear, the individual hails the vessel again to initiate
communication.
What is a DSC call?
A relatively new technology, digital selective calling (DSC) gives you
the capability to dial another boat directly via the vessel's MMSI (Maritime Mobile Service Identity) number, which functions much like a
phone number. Digital Selective Calling simplifies the calling process,
because you don't have to hail the vessel on Ch. 16 nor do you have to
verbally direct them to the working channel you want them to switch to
for communication. When their DSC radio receives your call, it automatically will switch to the channel you selected for communication.
The primary reason DSC was created was to enhance boater safety. It
does this in several ways. When working in tandem with a GPS unit, it
helps the Coast Guard respond more quickly to a Distress Call, since
the location of the vessel in distress will be automatically transmitted
when the signal is sent out. It will automatically repeat a distress signal every four minutes. That would come in handy if, as in the case of a
fire, you could not man the radio and fight the fire at the same time.
DSC calling also helps cut back the transmission traffic on Ch. 16, the
emergency priority channel.
How DSC works
A digital selective call uses a digital signal to transmit a pack of information that can include, the caller’s MMSI number, the MMSI of the
ship or ships being called, call priority and a frequency or mode request.
Location and time of location may be entered manually or if an active
GPS unit is attached, transmitted automatically. DSC calls allow you
to contact a specific ship, a group of ships, a specific group of DSC
receivers, ships in a particular geographic area or all ships within
range of you. A DSC call may even be patched into a regular phone line
through a commercial coastal station. One of the key elements of a DSC
call is the ability to place an individual call directly to another vessel.
Simplex or Duplex
References to simplex and duplex channels are scattered throughout
this manual. Simplex channels transmit and receive messages on the
same frequency. Like a CB radio, only one message can be transmitted
at a time. A duplex channel transmits and receives messages on different frequencies. Like a telephone, it gives users the capability to
transmit and receive messages at the same time. You must choose a
simplex channel when making a DSC call!
MMSI (Maritime Mobile Service Identity)
Your Maritime Mobile Service Identity number (MMSI) is like a home
phone number. Other DSC (Digital Selective Calling) radios must enter
your number before they can contact you. But first, you must program
your number into your radio. If your MMSI number is not set up, the ID
ANNUNCIATOR will blink on the display.
CAUTION
You only have one chance to program your MMSI into your radio. Study this section carefully to ensure the MMSI is entered
correctly.
The figure above illustrates the MMSI number entry of 992344513.
If a valid MMSI is already stored in the radio's memory, you will not be
able to enter a MMSI number. If a 9-digit MMSI number has not been
programmed into the radio, you will not be able to make or receive DSC
calls. To enter your assigned MMSI number, follow the steps listed in
the MMSI Setup below.
Warning
Again, there is only one chance to do this procedure correctly,
so go over this section carefully.
MMSI Setup
1. Hold down the CALL key for 5 seconds. The ID ANNUNCIATOR will blink
and a large "0" will be displayed alongside a small “16.” The big number “0” is the MMSI digit you are entering and the small digit “16” is
the first MMSI character field position. For example, a small digit "2"
represents the 2nd number from the left in your assigned MMSI. If the
number was "4" it would mean the big digit you were entering was the
4th number from the left and so on.
This example gives us a closer look at a number sequence from a MMSI entry.
The big numbers are the MMSI digits. The small numbers in the lower right
hand corner represent the digits' character field position. The big digit 4 is the
sixth number from left in the MMSI. The big digit 5 is seventh from left and
the big digit 1 is eighth from left.
NOTE
You need only to modify the big (MMSI) digits. The small digits
(character field position of the MMSI digit) will be generated automatically.
2. Use the Selector to enter the first digit of your MMSI number, then
press the MEM key to advance to the second digit. The small digit now
displays the 2nd character position with a big-digit "0" and small-digit
"2”. Press the Selector to set the second MMSI digit and touch the MEM
key to store. Repeat the operation until all 9 digits have been entered.
After inputting your MMSI, press the MEM key to double-check each
digit.
NOTE
If there is an error in the entry procedure, press the 16/9 key to exit.
You can also turn off the radio to ensure the MMSI won't be stored.
After you are satisfied with the MMSI number you have entered, hold
down the CALL key for 5 seconds to store the number. The ID ANNUCIATOR
will stop blinking and the radio reverts to the main screen. Now you
are ready to make a DSC call.
Choosing a Channel
Before making a call to another vessel, check the VHF chart in the back
of this manual. You'll have to choose a simplex communication channel
authorized for the type of communication you desire.
Making a Call
The MT-300 supports five DSC call types: ALLSHIPS CALL, DIRECTORY CALL,
LAST CALL, NEW CALL and DISTRESS CALL. The example below details a NEW
CALL. For information on the other call types, see page 13.
To place a DSC call
New Call
1. Select a simplex channel and press the CALL key once. LAST blinks.
2. Use the Selector to select NEW CALL.
3. Press the CALL key again. You can now enter the MMSI data of the
vessel you want to contact.
4. Use the Selector to enter the MMSI numbers, pressing MEM after
each digit. After completing MMSI entry, press the MEM key to verify
each number of the MMSI.
5. Press the CALL key and the radio will transmit the request. If there
is no ACK after 4 seconds, the radio transmits the call again. The radio
will stay in standby mode until an ACK is received, indicated by the
flashing ID Annunciator. If an ACK is not received, you can press the
call key again and the call is placed again. You can exit the call func10
tion at any time by pressing the 16/9 key twice.
CAUTION
Before transmitting, monitor the selected simplex channel to make
sure it is clear. This is a FCC requirement.

For more in depth information on placing calls see page 13.
To place a non-DSC call:
When making a non-DSC call, you'll have to switch to a communication
channel after making initial contact, so be sure to select a channel authorized for the type of communication you desire.
1. Select an appropriate communication channel.
2. Tune your radio to Ch. 16 or Ch. 9. Speak slowly and clearly, stating
the name of the vessel you are trying to contact followed by "this is
(your ship name and call sign)."
3. When the other vessel responds, say "go to (the desired channel
number) over."
4. Switch to the other working channel. After you are sure it is clear,
call out to the other vessel, stating the vessel's name, followed by "this
is (your ship name and call sign)."
Receiving a Call
Reception of an individual call automatically establishes communication on the working channel requested by the caller. Your radio transmits an ACK (Acknowledgement) message back to the calling radio. If
the calling vessel’s MMSI matches a number stored in your directory,
11
the number's directory location is shown. If no match is made, the ID
ANNUNCIATOR blinks. If you want to respond to the calling vessel, just
press the PTT button on the microphone. Press the 16/9 key to ignore
the call. See page 18 to get more detailed information on call reception.
12
Section 3: Advanced Operation
This section will give a more detailed explanation of what your radio
can do. We'll start off with a breakdown of the types of DSC calls the
MT-300 can transmit and receive. That will be followed by a brief description of how to place a non-DSC call. If you are comfortable with
your knowledge regarding transmission and reception of calls, skip
ahead to page 20 to see how to set up a MMSI Directory. On page 27,
there is information on the radio's weather function.
Calls
Transmission
The five DSC calling modes are:
1. AllShips Call: places a call to any ship in range of you.
2. Directory Call: dials number from MMSI directory.
3. Distress Call: executes an emergency call to Coast Guard and other
ships in range of you.
3. Last Call: dials last incoming call.
4. New Call: places call to caller not in the MMSI directory.
Press CALL then use the Selector to scroll through the four choices (DISTRESS CALL is a separate function, so it is not included in the calls menu).
The LAST CALL option always appears first.

Distress Call
In an emergency situation, lift the red cover on the front panel to make
a Distress call to the Coast Guard. Press and hold the DISTRESS key for
14
three seconds. The radio switches to Ch. 16 and a three-second on
screen timer begins to count down in the bottom right corner of the
screen. When it reaches zero, the call is sent out. To stop the call, let go
of the DISTRESS key. No message will be sent unless the timer counts
down to zero. Press the 16/9 key to cancel.
NOTE
If an inadvertent Distress call is sent out, make sure you're on Ch.
16 and quickly transmit a message to all vessels, canceling the Distress call.
3-second

message again every 4 minutes. A DISTRESS WAIT message will be displayed on the screen.
NOTE
The Coast Guard is the only agency allowed to acknowledge a Distress call. An individual vessel's DSC radio will not automatically
respond with an acknowledgement.
15
When an ACK is received, the distress mode is automatically canceled and communication will be on Ch. 16.
Last Call
You can send a last call by following this sequence:
1. Use the to select a simplex-working channel. The radio will default
to Ch. 16 if a duplex channel is selected. (If you press the call key during WX CHANNEL MODE, the last used channel is displayed.)
2. Press the CALL key.
3. LAST blinks.

Channels
To tune into one of the 84 channels on the MT-300 radio, use the Selector to scroll through the channels. Refer to the enclosed channel chart
in the back of this book for proper usage and understanding. In the US
and Canada, WX (Weather) channels are available. WX channels are not
available for international use.
An A ANNUNCIATOR will be displayed when an alternate channel is used.
That is telling you the radio is tuned to a simplex channel and normal
ship-to-ship communication is appropriate. If the A ANNUNCIATOR is off,
the radio is operating in duplex mode.
Channel Bank
The Channel Bank has three settings, one each for US, Canada and
International use. Press and hold the H/L and WX keys at the same time
to switch channel banks. The annunciator will display USA, INT or CAN
based on your selection. Refer to the channel chart appendix for proper
usage.

number will increase each time you add a MMSI digit. Use the Selector
to set the second MMSI digit and touch the MEM key to store. Repeat
the operation until all 9 digits have been entered and verified. After
entering the MMSI, review each digit by pressing the MEM key. If there
is a mistake, press the 16/9 key to exit or just turn off the radio. The
MMSI will not be stored. After you are satisfied with your MMSI entry,
hold down the CALL key for 5 seconds to store the number.
6. Press the 16/9 key to revert to the main screen.
20
The example shows the MMSI Data 987776510 being entered.
To change or edit MMSI data, select a FL location and press the MEM
key to change the data. After inputting the 9-digit MMSI, hold down
the CALL key for 5 seconds to store the new MMSI.
DSC Monitor
To be sure the DSC Monitor mode is on, hold down the CALL key for 5
seconds to toggle the DSC Monitor mode off and on. It must be on for
your radio to receive a DSC call. The DSC MON ANNUNCIATOR will be displayed onscreen, if Ch. 70 is being accessed. Since there is no independent Ch. 70 receiver, the radio normally monitors Ch. 70 and checks
other channels on a regular basis to detect a squelch break. This
method ensures the radio will acquire the most DSC calls possible.
21
DSC Monitor must be
on for radio to receive
calls
NOTE
DSC calls will NOT be received when the radio is receiving or sending out a transmission. During scanning, Ch. 70 is monitored on an
allocated time-slot basis and DSC calls will be received.
GPS Operation
Your radio is NMEA 0183 compatible, which means it can work with a
GPS unit. To be certain your location is autom+atically transmitted
during a distress call, make sure your GPS unit is on and operational
at all times. The GPS data is sent through Ch. 70 to the coast guard
and is the primary starting point of any search and rescue mission. If
THE GPS ANNUNCIATOR is blinking, the GPS data is not valid.
GPS
Annunciator
H/L
The H/L key gives you control over the radio's wattage. The high-end is
25 Watts. The low-end is 1 Watt. If the LO ANNUNCIATOR is off, the radio
will transmit at 25 Watts. Some channels do not accept transmissions
or are restricted to a 1-Watt level. If you come across one of those channels and you try to switch to 25W, you will hear a 3-tone error beep,
meaning you either can not transmit on that channel or it only accepts
transmissions at the 1W (Lo) level.
Memory Operation
Normally, the MEM ANNUNCIATOR appears on the display to alert the user
the channel is stored in the memory channel list. The following figure
shows Ch. 8 is stored in memory.
22
You can easily add or delete channels from the memory channel list.
For your safety, DO NOT delete priority Ch. 16.
To add a new channel, use the Selector to select the desired channel
(shown above in big digits). If the channel is currently stored as a
memory channel, the MEM ANNUNCIATOR will be displayed.
To add a new channel to the list, hold down the MEM key until the MEM
ANNUNCIATOR appears. The new channel is now added to the list. To delete a channel from the list, use the Selector to choose a channel saved
in the memory list. You will know a channel from the memory list has
been chosen when the MEM Annunciator appears on the screen. Hold
down the MEM key for three seconds to delete the channel. The MEM
ANNUNCIATOR no longer will be displayed when the channel is tuned in.
NOTE
To clear and reset all the memory channels, hold down the MEM key
while turning on the radio. This clears all memory channels with
the exception of the Priority Channel.
Position Send/Request
Transmission
Your radio can send and receive information on location if it is connected to a GPS unit. This will allow you to locate a vessel without
transmitting messages back and forth.
To send your position (P1):
1. Press the CALL key, then use the Selector to select DIR from the
main screen and press Call.
2. To edit or enter the P1 memory location, use the Selector to select
position P1 from the directory. P1 will be displayed in the bottom right
corner of the display. If the P1 location has CL in the window, you must
enter the MMSI of the vessel to which you're trying to send your position. Press MEM and use the Selector to enter the MMSI numbers,
pressing MEM after each digit has been entered. When finished, press
and hold the CALL key for five seconds. The screen will show FL P1, letting you know the MMSI is now stored in the P1 location. The MMSI
number will be stored in the P1 location until you edit or replace the
MMSI information.
23
3. Press the Call key and the big digit will blink and the channel will
switch to Ch. 16. Press the CALL key again and the position data will be
sent through Ch. 70. After the transmission on Ch. 70, the ID Annunciator will flash, indicating it is waiting for an ACK. If an ACK is not
received, another call can be made to send your position to the same
MMSI by pressing the CALL key. When the position send is acknowledged, an alarm will be heard. Press the 16/9 key to cancel the alarm.
4. Press 16/9 key to return to the main screen.
To request a position (P2):
1. Press CALL, then use the to select DIR from the main screen.
2. To edit or enter the P2 location, use the Selector to select position P2
from the directory. P2 will be displayed in the bottom right corner of
the display. If the P2 location has CL in the window, you must enter the
MMSI of the vessel from which you're trying to request a position.
Press MEM and use the Selector to enter the MMSI numbers, pressing
MEM after each digit has been entered. When finished, press and hold
the CALL key for five seconds. The screen will show FL P2, letting you
know the MMSI is now stored in the P2 location. The MMSI number
will be stored in the P2 location until you edit or replace the MMSI
information.
3. Press the CALL key and the big digit will blink and the channel will
be switched to Ch. 16. Press the CALL key again and the position data
will be requested through Ch. 70. After the transmission on Ch. 70, the
ID Annunciator will flash, indicating it is waiting for an ACK. If an ACK
is not received, another call can be made to request the position of the
same MMSI by pressing the CALL key. When the position request is
acknowledged, an alarm will be heard. Press the 16/9 key to cancel the
alarm.
4. Press 16/9 key to return to the main screen. The vessel's location will
be displayed on the GPS map.

3. To ignore the position request, press the 16/9 key to silence the alarm,
then press it again to return to the main screen.
Priority Channel (16/9)
The 16/9 key is used to switch priority channels. When you first turn on
the radio, its default priority channel is Ch. 16. To switch priority
channels, hold down the 16/9 key for a few seconds until the priority
channel switches to the other channel. This is particularly useful when
you want to make a non-DSC call and Ch. 16 is receiving a lot of
transmission traffic. The 16/9 key also allows you to exit various operation modes, ignore incoming calls and cancel outgoing calls.
With a quick press of the 16/9 key the priority channel immediately is
selected with high (25W) transmission power. Press the 16/9 key again
and it selects the last used channel.
PTT (Push To Talk)
This key is on the microphone. Press and hold it down to send a transmission. There is a 5-minute maximum transmission timer, per FCC
regulations.
Scan
There are three primary scanning modes, ALLSCAN, MEMORY SCAN, and
PRIORITY SCAN.
25
NOTE
Remember, you cancel any scan mode at anytime by pressing the
16/9 or SCN key.
To start an All Scan
To scan through all available channels, press and hold the SCN key for
three seconds. ALL SCN will appear on the display. The radio now will
scroll through every available channel as it scans.
A noisy channel that interrupts the scanning can be temporarily eliminated from the scan list by holding down the MEM key. The channel
receiving the signal will be skipped, allowing the scanning to continue
uninhibited. Turning the radio off and on again will restore all the
channels back to the ALLSCAN memory list.
To start a Memory Scan
To scan through channels in the memory scan list, press the MEM key,
then push the SCN key. If you are in a different scanning mode, you
must stop the scan before switching to a MEMORY SCAN. In that case,
press SCN|MEM|SCN.
To add channels to the memory scan list, use the Selector to tune in
each of the channels you want to monitor. As you tune in each channel,
depress MEM for three seconds to add it to the memory list. The MEM
Annunciator will appear, letting you know the channel has been added
to memory..
While in the MEM scan mode, touch the WX key to toggle the WX ALERT
function off and on. The scan will stop when a channel picks up a signal.
The scan will not continue until the input signal stops. To stop scanning, press the SCN key or the 16/9 key. Press in the PTT button exits
the scan mode at the last channel display.
To start a Priority Scan
Pressing the SCN key activates the PRIORITY SCAN mode. P SCAN will ap-
26
pear on the display. The priority channel is scanned every 2 seconds,
even if another channel has a squelch break.
When a signal is received on the priority channel, the scan stops and
the radio receives the priority transmission. WX ALERT can be toggled off
and on by pressing the WX key.
Screen
When the unit is turned on the LCD light display is on and stays on.
There is no contrast control.
Weather (Wx)
Dark clouds on the horizon? Press the WX key to enter the WX (WEATHER)
MODE and get the latest weather information. The last used Wx channel
always appears first. Use the Selector to change the WX channel. In
PRIORITY SCAN or MEMORY SCAN MODES, pressing the WX key allows the WX
ALERT function to be toggled off and on. Select the WX channel before
starting a PRIORITY SCAN or MEMORY SCAN.
If a WX ALERT – a 1050Hz-tone burst transmitted from the NOAA
Weather service – is issued, a special circuit in the radio detects the
tone and during scanning modes (except All Scan), a loud 2-tone warning will sound. The warning tone is canceled by pressing any key. The
radio will stop scanning and switch to the WX channel to broadcast the
warning. You know the radio is scanning the WX channel, if you see the
WX ANNUNCIATOR flash as it scans through the weather channels.
