7 GETTING STARTED
7.1 ABOUT VHF RADIO
The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with
some shore stations available between 161 and 163 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 25W radio transmission expected distances can be greater than 25 km.
7.2 SELECTING AN ANTENNA
Marine antennas are made to radiate signals equally in all horizontal directions, 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, 3dB gain antenna represents twice as much gain
over the imaginary antenna.
Typically a 1 m 3dB gain stainless steel whip is used on a sailboat mast. The longer 2.5 m
6dB fiberglass whip is primarily used on power boats that require the additional gain.
7.3 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 6 mm in diameter is a good choice. For runs over 6
m but less than 15 m, the larger RG-8X should be used for cable runs over 15 m RG213
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 are
supplied with the connector. Be sure to make good soldered connections.
8 INSTALLATION
8.1 LOCATION
The radio can be mounted at any angle. Choose a mounting location that:
• keeps the radio and microphone at least 1 m away from your vessel’s magnetic
navigation compass
Vertex Standard Co., Ltd. 8

IC ID: 511B-30283X3S
GX5000S / GX5500S Operating Manual
• 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
• the antenna must be mounted at least 1 m from radio
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 desired 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.
8.2 MOUNTING THE RADIO
8.2.1 Supplied Universal Mounting Bracket
The supplied universal mounting bracket allows overhead or desktop mounting.
Use a 5.2-mm (17/64”) bit to drill the holes to a surface which is more 10 mm thick and can
support more than 5 kg and secure the bracket with the supplied screws, spring washers,
flat washers, and nuts.
8.2.2 Optional MMB-84 Flush Mount Bracket
1. To assist in flush mounting, a template has been included. Use this template to
assess the mounting location.
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 accommodate the transceiver
(at least 15 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 nut
combination; so that the mounting screw base faces the mounting surface (see

1PM, setup as in previous section and confirm the alert is heard.
10.7 EMERGENCY (CHANNEL 16 USE)
Channel 16 is known as the Hail and Distress Channel. An emergency is 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, Mayday. 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 magnetic 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), colour 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 response, try
another channel.
10.8 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)
Channel 16 may be used for initial contact (hailing) with another vessel.
However, its most important use is for emergency and distress messages. This channel
must be monitored at all times except when actually using another channel.
It is monitored by the European, U.S. and Canadian Coast Guards and by other vessels.
Use of channel 16 for hailing must be limited to initial contact only. Calling should not
exceed 30 seconds, but may be repeated 3 times at 2-minute intervals. In areas of heavy
radio traffic, congestion on channel 16 resulting from its use as a hailing channel can be
reduced significantly in U.S. waters by using channel 9 as the initial contact (hailing)
channel for non-emergency communications. Here, also, calling time should not exceed 30
seconds but may be repeated 3 times at 2-minute intervals.
Prior to making contact with another vessel, refer to the channel charts in this manual, and
select an appropriate channel for communications after initial contact. For example,
Vertex Standard Co., Ltd. 23
FCC ID: K6630283X3S
IC ID: 511B-30283X3S
GX5000S / GX5500S Operating Manual
Channels 68 and 69 are some of the channels available to non-commercial (recreational)
boaters. Monitor your desired channel in advance to make sure you will not be interrupting
other traffic, and then go back to either channel 16 or 9 for your initial contact.
When the hailing channel (16 or 9) is clear, state the name of the other vessel you wish to
call and then “this is” followed by the name of your vessel and your Station License (Call
Sign). 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 microphone’s push-to-talk (PTT) switch.
When all communication with the other vessel is completed, end the last transmission by
stating your Call Sign and the word “out.” Note that it is not necessary 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.
10.9 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 Public 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.
10.10 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 channels. However, in
certain situations it may be necessary to temporarily use a higher power. See page 20
([H/L(NAV)] key) for means to temporarily override the low-power limit on these two
channels.

WARNING
This radio is designed to generate a digital maritime distress and safety call to facilitate
search and rescue. To be effective as a safety device, this equipment must be used only
within communication range of a shore-based VHF marine channel 70 distress and safety
watch system. The range of signal may vary but under normal conditions should be
approximately 20 nautical miles.
Digital Selective Calling is a semi-automated method of establishing a radio call, it has
been designated by the International Maritime Organization (IMO) as an international
standard for establishing VHF, MF, and HF radio calls. It has also been designated as part
of the Global Maritime Distress and Safety System (GMDSS). It is planned that DSC will
eventually replace aural watches on distress frequencies and will be used to announce
routine and urgent maritime safety information broadcasts.
This system allows mariners to instantly send a distress call with GPS position (when
connected to the transceiver) to the Coast Guard and other vessels within range of the
transmission. DSC will also allow mariners to initiate or receive Distress, Urgency, Safety,
Routine, POSITION REQUEST, POSITION SEND, and Group calls to or from another
vessel equipped with a DSC transceiver.

11.8 POSITION REQUEST
Advancements in DSC have made it possible to poll the location of another vessel and
show the position of that vessel on the display of the GX5000S/GX5500S. Standard
Horizon has taken this feature one step further, if any Standard Horizon GPS is connected
to the GX5000S/GX5500S, the polled position of the vessel is shown on the display of the
GPS chart plotter making it easy to navigate to the location of the polled vessel. This is a
great feature for anyone wanting to know the position of another vessel. For example your
friend that is catching fish, or finding the location of a person you are cruising with.
NOTE
The other vessel must have an operating GPS receiver connected to its DSC transceiver
and must not have its transceiver set to deny position requests. (Refer the section “11.5.1
Setting up the Individual / Position Call Directory” to enter information into the individual
directory).
11.8.1 Setting up Position Reply
The GX5000S/GX5500S can be set up to automatically or manually send your position to
another vessel. This selection is important if you are concerned about someone polling the
position of your vessel that you may not want to. In the manual mode you will see the MMSI
or persons name shown on the display allowing you to choose to send your position to the
requesting vessel.

many years of continuous use. Taking the following precautions however, will prevent
damage to the transceiver.
• Keep the microphone connected or the jack covered at all times to prevent corrosion
of electrical contacts;
• Never key the microphone unless an antenna or suitable dummy load is connected to
the transceiver.
• Ensure that the supply voltage to the transceiver does not exceed 16 VDC or fall
below 11 VDC.
• Use only STANDARD HORIZON-approved accessories and replacement parts.
In the unlikely event of serious problems, please contact your Dealer or our repair
facility.

15.3 TROUBLESHOOTING CHART
16 CHANNEL ASSIGNMENTS
Tables on the following columns list the VHF Marine Channel assignments for U.S.A. and
International use. Below are listed some data about the charts.
1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s Vessel
Traffic System.
2. Alpha channel numbers, that is, channel numbers followed by the letter A (such as
Channel 07A) are simplex channels on the U.S.A. or Canadian channel assignments
whose counterparts in the International assignments are duplex channels.
International channels do not use “alpha” numbers. If you call the Coast Guard on
Channel 16, they will sometimes ask you to “go to channel 22 Alpha.” This is a
channel assigned to U.S.A, and Canadian Coast Guards for handling distress and
other calls. If your radio is set for International operation you will go to Channel 22
instead of 22A, and will not be able to communicate with the Coast Guard. To use
Channel 22A, your radio must be set for USA or Canada operation, usually by a U/I/C
(USA/International/Canada) control or combination of controls. Channel 22 (without
an “A”) is an International duplex channel for port operations. Some radios indicate
an “A” adjacent to the alpha channels on the display; on others “alpha” is not
indicated but the proper channel is selected based on the U/I/C setting.
3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge operators
on intercoastal waterways and rivers. It is also used by marine vessels in the vicinity
of these bridges for navigation and for communicating with the bridge operators. Note
that a limit of 1 Watt is specified for these channels. See page 28 for additional
information.
4. The S/D column on the chart indicates either S (simplex) or D (duplex). Simplex
means transmitting and receiving on the same frequency. Only one party at a time
can talk, unlike a telephone. Be sure to say “over” and release your microphone
push-to-talk switch at the end of each transmission. Duplex operation involves the
use of one frequency for transmitting and a separate frequency for receiving. On
channels specified as duplex on the charts, correct mode of operation is established
automatically by your radio when you select a channel; you cannot change the mode.

IC ID: 511B-30283X3S
GX5000S / GX5500S Operating Manual
And you still must release the push-to-talk switch after each transmission in order to
listen to the radio.
5. Channels normally used by recreational boaters are those that include the term
“non-commercial” in the Channel Use column of the chart. Some of these are shared
with other users and some are used only in certain geographic regions.
6. Marine vessels equipped with VHF radios are required to monitor Channel 16.
