1 GENERAL INFORMATION
The STANDARD HORIZON MATRIX Series GX2000E and GX2100E Marine
VHF/FM Marine transceiver are designed to be used in International, Cana-
dian, and USA Marine bands. The GX2000E and GX2100E can be operated
from 11 to 16 VDC and has a switchable RF output power of 1 watt or 25 watts.
MATRIX AIS GX2100
Integrates a dual channel AIS (Automatic Identification System) receiver to
display AIS vessel information (MMSI, Call Sign, Ship Name, BRG, DST, SOG
and COG) directly on the VHF radio, so you will know what is out there in any
conditions. The GX2100E is also capable of entering and saving up to 100
waypoints, which may be selected and navigated to by using a unique naviga-
tion compass display. The MATRIX AIS allows you to contact an AIS Ship
directly using DSC, show your vessels position in relation to AIS targets and
alert you when an AIS ship may be approaching too close to your location via
the Closest Point of Approach (CPA) Alarm. To receive AIS targets from ships
with AIS class A or B transponders, simply connect the normal VHF antenna
(only one antenna needed!)
MATRIX - GX2000E
For the mariner who already has AIS on-board and desires a VHF with the
features of the MATRIX AIS, the MATRIX GX2000E has a connection for an
AIS receiver or transponder.
The MATRIX Series VHF’s are capable of DSC (Digital Selective Calling) Class
D operation. Class D operation allows continuous receiving of Digital Selective
Calling functions on channel 70 even if the radio is receiving a call. The MA-
TRIX Series VHF’s operate on all currently-allocated marine channels which
are switchable for use with International, Canadian, or USA regulations. Emer-
gency channel 16 can be immediately selected from any channel by pressing
the red [16/9]key.
Other features of the MATRIX Series VHF’s include: Speaker Microphone,
30W PA/Fog, optional RAM3 second station remote-control microphone with
display, intercom between radio and optional RAM3, scanning, priority scan-
ning, submersible speaker mic, high and low voltage warning, and GPS re-
peatability.
The MATRIX series also support ATIS modoe, which is used in the inland
waterways of Europe. Please contact your local PTT adminstratioon or Marine
Authority to obtain your ATIs number.
ATIS operation is explained in Chapter 15 of this user manual.

4 SAFETY / WARNING INFORMATION
IMPORTANT SAFETY INFORMATION
Please read this manual carefully to become familiar with the features
of this transceiver before using it for the first time.
The installation of this equipment should be made in such a manner as to
respect the EC recommended electromagnetic field exposure limits (1999/519/
EC).
The maximum RF power available from this device is 25 W. The antenna should
be mounted as high as possible for maximum efficiency and that this installa-
tion height should be at least 5 meters above ground (or accessible) level. In
the case that an antenna can not be installed at a reasonable height, then the
transmitter should neither be continuously operated for long periods if any
person is within 5 metres of the antenna, nor operated at all if any person is
touching the antenna. non compliance with these recommendations and trans-
mitting for more than 50% of the total radio use time (50 % duty cycle) may
cause RF complaince exposure requirements to be be exceeded.
In all cases any possible risk depends on the transmitter being activated for
long periods (actual recommendation limits are specified as an average of 6
minutes). Normally the transmitter is not active for long periods of time. Some
radio licenses will require that a timer circuit automatically cuts the transmitter
after 1 - 2 minutes.
Do not transmit without an antenna connected to the radio. When transmitting
speak into the microphone holding it between 1.5 cm and 5 cm from your
mouth.
The radio must be used with a maximum operating duty cycle not exceeding
50 % in normal PTT configurations. Do not transmit for more than 50 % of the
total radio use time (50 % duty cycle)

Page 11GX2000E/GX2100E
5 GETTING STARTED
5.1 ABOUT VHF RADIO
The radio frequencies used in the VHF marine band lie between 156 and 162
MHz. The marine VHF band provides communications over distances that are
essentially “line of sight” (VHF signals do not travel well through objects such
as buildings, hills or trees). Actual transmission range depends much more on
antenna type, gain and height than on the power output of the transmitter. On
a fixed mount 25 W radio transmission expected distances can be greater
than 25 km, for a portable 5W radio transmission the expected distance can
be greater than 8 km in “line of sight”.
5.2 SELECTING AN ANTENNA
Marine antennas are made to radiate signals equally in all horizontal direc-
tions, but not straight up. The objective of a marine antenna is to enhance the
signal toward the horizon. The degree to which this is accomplished is called
the antenna’s gain. It is measured in decibels (dB) and is one of the major
factors in choosing an antenna. In terms of effective radiated power (ERP),
antennas are rated on the basis of how much gain they have over a theoretical
antenna with zero gain. A 1 m, 3 dB gain antenna represents twice as much
gain over the imaginary antenna.
Typically a 1 m 3 dB gain stainless steel whip is used on a sailboat mast. The
longer 2.5 m 6 dB fiberglass whip is primarily used on power boats that require
the additional gain.

GX2000E/GX2100EPage 12
5.3 COAXIAL CABLE
VHF antennas are connected to the transceiver by means of a coaxial cable –
a shielded transmission line. Coaxial cable is specified by it’s diameter and
construction.
For runs less than 6 m, RG-58/U, about 1/4 inch in diameter is a good choice.
For runs over 6 m but less than 15 m, the larger RG-8X or RG-213/U should be
used for cable runs over 15 m RG-8X should be used. For installation of the
connector onto the coaxial cable refer to the figure below.
To get your coax cable through a fitting and into your boat’s interior, you
may have to cut off the end plug and reattach it later. You can do this if
you follow the directions that come with the connector. Be sure to make
good soldered connections.

5.4 EMERGENCY (CHANNEL 16 USE)
Channel 16 is known as the Hail and Distress Channel. An emergency may be
defined as a threat to life or property. In such instances, be sure the transceiver
is on and set to CHANNEL 16. Then use the following procedure:
1. Press the microphone push-to-talk switch and say “Mayday, Mayday, May-
day. This is , , ” (your vessel’s name).
2. Then repeat once: “Mayday, ” (your vessel’s name).
3. Now report your position in latitude/longitude, or by giving a true or mag-
netic bearing (state which) to a well-known landmark such as a navigation
aid or geographic feature such as an island or harbor entry.
4. Explain the nature of your distress (sinking, collision, aground, fire, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance your desire (pumps, medical aid, etc.).
6. Report the number of persons aboard and condition of any injured.
7. Estimate the present seaworthiness and condition of your vessel.
8. Give your vessel’s description: length, design (power or sail), color and
other distinguishing marks. The total transmission should not exceed 1
minute.
9. End the message by saying “OVER”. Release the microphone button and
listen.
10. If there is no answer, repeat the above procedure. If there is still no re-
sponse, try another channel.
NOTE
The GX2000E and GX2100E have DSC Distress calling, that can trans-
mit a distress call digitally to all ships with compatible DSC radios. Refer
to section “9 DIGITAL SELECTIVE CALLING”.

GX2000E/GX2100EPage 14
5.5 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)
Channel 16 should be used as the calling channel for initial contact with an-
other vessel, however its primary purpose is for emergency communications
and should be monitored at all times when not using other channels.
It is monitored by Coast Guard stations in all countries and other vessels.
The use of Channel 16 should be limited to making initial contact only. Calling
should not exceed 30 seconds, but may be repeated at 2 minute intervals.
Prior to making contact with another vessel, refer to the channel charts in this
manual and select an appropriate channel (working channel) for use after ini-
tial contact. Monitor the proposed channel to ensure you will not be interruptng
other traffic and then go back to Channel 16 to make your initial call.
When the calling chqannel 16 is clear, state the name of the vessel you wish to
call and then “this is” followed by the name of your vessel and your vessel
callsign. When the other vessel returns your call, immediately request another
channel by saying “go to”, the number of the other channel, and “over”. Then
switch to the new channel. When the new channel is not busy, call the other
vessel.
After a transmission, say “over”, and release the PTT (Push-To-Talk) switch.
When all communication with the other vessel is completed, end the last trans-
mission by stating your Call Sign and the word “out”. Note that it is not neces-
sary to state your Call Sign with each transmission, only at the beginning and
end of the contact.
Remember to return to Channel 16 when not using another channel. Some
radios automatically monitor Channel 16 even when set to other channels or
when scanning.
5.6 MAKING TELEPHONE CALLS
To make a radiotelephone call, use a channel designated for this purpose, The
fastest way to learn which channels are used for radiotelephone traffic is to
ask at a local marina. Channels available for such traffic are designated Pub-
lic Correspondence channels on the channel charts in this manual. Some
examples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87.
Call the marine operator and identify yourself by your vessel’s name, The marine
operator will then ask you how you will pay for the call (telephone credit card,
collect, etc.) and then link your radio transmission to the telephone lines.
The marine telephone company managing the VHF channel you are using
may charge a link-up fee in addition to the cost of the call.

5.7 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks and bridges and by vessels maneuvering in port.
Messages on this channel must concern navigation only, such as meeting and
passing in restricted waters.
Channel 67 is used for navigational traffic between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your
radio is programmed to automatically reduce power to this limit on these chan-
nels. However, in certain situations it may be necessary to temporarily use a
higher power. See page 30 ([H/L]key) for means to temporarily override the
low-power limit on these two channels.

6 INSTALLATION
6.1 LOCATION
The radio can be mounted at any angle. Choose a mounting location that:
• is far enough from any compass to avoid any deviation in compass read-
ing due to the speaker magnet
• provides accessibility to the front panel controls
• allows connection to a power source and an antenna
• has nearby space for installation of a microphone hanger
• choose a mounting location that is at least 1 m away from the radio’s
antenna.
Note: To insure the radio does not affect the compass or radios performance is
not affected by the antenna location, temporarily connect the radio in the de-
sired location and:
a. Examine the compass to see if the radio causes any deviation
b. Connect the antenna and key the radio. Check to ensure the radio is
operating correctly by requesting a radio check.
6.2 MOUNTING THE RADIO
6.2.1 Supplied Mounting Bracket
The supplied mounting bracket allows overhead or desktop mounting.
Use a 5 mm bit to drill the holes to a surface which is more 10 mm thick and
can support more than 1.5 kg and secure the bracket with the supplied screws,
spring washers, flat washers, and nuts.
DESKTOP MOUNTING OVERHEAD MOUNTING

Page 17GX2000E/GX2100E
6.2.2 Optional MMB-84 Flush Mount Bracket
1. Make a rectangular template for the flush mount measuring 65 x 161 mm.
2. Use the template to mark the location where the rectangular hole is to be
cut. Confirm the space behind the dash or panel is deep enough to accom-
modate the transceiver (at least 17 cm deep).
There should be at least 1.5 cm between the transceiver’s heatsink and
any wiring, cables or structures.
3. Cut out the rectangular hole and insert the transceiver.
4. Fasten the brackets to the sides of the transceiver with the lock washer
screw combination; so that the mounting screw base faces the mounting
surface (see illustration below).
5. Turn the adjusting screw to adjust the tension so that the transceiver is
tight against the mounting surface.

6.3 ELECTRICAL CONNECTIONS
CAUTION
Reverse polarity battery connections will damage the radio!
Connect the power cord and antenna to the radio. Antenna and Power Supply
connections are as follows:
1. Mount the antenna at least 1 m away from the radio. At the rear of the
radio, connect the antenna cable. The antenna cable must have a PL259
connector attached. RG-8/U coaxial cable must be used if the antenna is
7.6 m or more from the radio. RG58 cable can be used for distances less
than 7.6 m.
2. Connect the red power wire to a 13.8 VDC ±20% power source. Connect
the black power wire to a negative ground.
3. If an optional remote extension speaker is to be used, refer to section 6.4
for connections.
4. It is advisable to have a Certified Marine Technician check the power out-
put and the standing wave ratio of the antenna after installation.
Fuse Replacement
To take out the Fuse from the Fuse Holder, hold
both ends of the Fuse Holder and pull the Fuse
Holder apart without bending the fuse Holder.
When you replace the Fuse, please confirm that
the Fuse is tightly fixed on the metal contact lo-
cated inside the Fuse Holder. If the metal contact
holding the fuse is loose, the Fuse holder may
heat up.

When making connections between the radio, chartplotter, GPS or AIS re-
ceiver or AIS transponder, ensure that the connections are robust and pro-
tected from shorting toether or to ground. Whether flush mounting the radio or
not, it is recommended that a waterproof 8 position screw terminal connector
block is fixed to the bulkhead adjacent to the rear of the radio and the connec-
tions to and from the radio are made via this connector block.
Note: In some areas powerful AM broadcast stations may be heard when in
listen-back mode. In this case change the speaker wire to 2-conductor shielded
audio cable. See the illustration below for connections.
