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 ma-
rine 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 15 miles.
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 3 foot, 3dB gain antenna represents twice as much gain over
the imaginary antenna.
Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. The
longer 8 foot 6dB fiberglass whip is primarily used on power boats that require
the additional gain.

Page 9GX3500S
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 20 feet, RG-58/U, about 1/4 inch in diameter is a good choice.
For runs over 20 feet but less than 50 feet, the larger RG-8X or RG-213/U
should be used for cable runs over 50 feet RG-8X should be used. For installa-
tion 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.

8 INSTALLATION
8.1 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
• the antenna must be mounted at least 3 feet 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 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.
8.2 ELECTRICAL CONNECTIONS
CAUTION
Reverse polarity connections will damage the radio!
Connect the power cord and antenna to the radio. Antenna and Power Supply
connections are as follows (see Figure 1):
1. Mount the antenna at least 3 feet away from the radio. At the rear of the
radio, connect the antenna cable. It must have a PL259 connector. RG-8/U
coaxial cable must be used if the antenna is 25 feet or more from the radio.
RG58 cable can be used for distances less than 25 feet.

ceiving on one of the NOAA weather channels.
10.6.2 NOAA Weather Alert Testing
NOAA tests the alert system ever Wednesday between 11AM and 1PM. To test
the QUANTUM’s NOAA Weather feature, on Wednesday between 11AM and
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 de-
fined 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.
Vertex Standard Co., Ltd.
FCC ID: K6630063X30 / IC ID: 511B-30063X30
Page 27GX3500S
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.
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 messages. This channel
must be monitored at all times except when actually using another channel.
It is monitored by the 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 inter-
vals. 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 communi-
cations. 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 con-
tact. For example, 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, immedi-
ately request another channel by saying “go to,” the number of the other chan-
nel, 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 begin-
ning 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.

GX3500SPage 28
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 ex-
amples 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 18 ([H/L] key) for means to temporarily override the low-power
limit on these two channels.
10.11 DUAL WATCH (TO PRIORITY CHANNEL)
Dual watch allows the radio to monitor one channel and the assigned Priority
channel. By default the priority channel is set to 16, however the priority chan-
nel may be changed by referring to section 12.5 Priority Channel set.
1. Adjust the SQL knob until the background noise disappears.
2. Select the channel you wish to dual watch to “Priority channel.”
3. Press the [F] key followed by the [4(DW)] key.
The display will scan between Priority channel and
the channel that was selected in step 2.
If a transmission is received on the channel selected
in step 2, the GX3500S will dual watch between the
working channel and the Priority channel.
4. To stop Dual Watch, press the [CLR] key or press the [F] key followed by
the [4(DW)] key again.

11 DIGITAL SELECTIVE CALLING
11.1 GENERAL
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 approxi-
mately 20 nautical miles.
NOTE
A DSC Warning sticker is included
with the GX3500S. To comply with
FCC regulations this sticker must be
mounted in a location that can be eas-
ily viewed from the location of the
GX3500S. Make sure the chosen lo-
cation is clean and dry before apply-
ing the sticker.
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 Sys-
tem (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 new system allows mariners to instantly send a distress call with GPS posi-
tion (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.

11.7 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 GX3500S.
Standard Horizon has taken this feature one step further, if any Standard Hori-
zon GPS is connected to the GX3500S, 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 buddy that is catching fish, or
finding the location of a person you are cruising with.
NOTE

14 MAINTENANCE
The inherent quality of the solid-state components used in this transceiver will
provide many years of continuous use. Taking the following precautions will pre-
vent 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 con-
nected 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.

SYMPTOM
Transceiver fails to
power up.
Transceiver blows fuse
when connected to
power supply.
Popping or whining
noise from the speaker
while engine runs.
Sound is not emitted
from the internal or ex-
ternal speaker.
Receiving station re-
port low transmit
power, even with trans-
ceiver set to HI power.
“HI BATTERY” or “LO
BATTERY” message is
appeared when the
power is turned on.
“PA ERROR” or “FOG
ERROR” message is
shown when the PA/
FOG mode is acti-
vated.
Your position is not dis-
played.
PROBABLE CAUSE
No DC voltage to the
transceiver, or blown
fuse.
Reversed power
wires.
Engine noise.
Accessory cable.
Antenna.
The power supply
voltage is too high or
too low.
Accessory cable.
Accessory cable.
Setting of the GPS
navigation receiver.
REMEDY
a. Check the 12VDC battery connections and
the fuse.
b. The PWR key needs to be pressed and held
to turn the radio on.
Check the power cable for DC voltage, or re-
place the fuse (6A 250V).
Make sure the red wire is connected to the posi-
tive (+) battery post, and the black wire is con-
nected to the negative (-) battery post. If the
fuse still blows, contact your Dealer.
Reroute the DC power cables away from the
engine. Add noise suppressor on power cable.
Change to resistive spark plug wires and/or add
an alternator whine filter.
Check the connections of the accessory cable
(Possible short circuit on the External speaker
cable WHITE/SHIELD).
Have the antenna checked or test the trans-
ceiver with another antenna. If the problem per-
sists, contact your Dealer for servicing.
Confirm that the connected power supply volt-
age is not 17 volts or lower than 10 volts. Con-
firm that the generator has not malfunctioned.
Check the accessory cable connection (Pos-
sible short circuit on the PA speaker cable RED/
SHIELD).
Check the accessory cable connection.
Some GPS use the battery ground line for
NMEA connection.
Check the output signal format of the GPS navi-
gation receiver. This radio requires NMEA0183
format with GLL, RMB, GGA, or GNS sentence
as an output signal. If the GPS has a baud rate
setting make sure to select 4800 and parity to
NONE.
14.3 TROUBLESHOOTING CHART

Page 77GX3500S
15. 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 Cana-
dian 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 communicat-
ing with the bridge operators. Note that a limit of 1 Watt is specified for
these channels. See page 27 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 transmis-
sion. 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. 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 geo-
graphic regions.
