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 installation 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 transmitting for more than 50% of the total radio use time (50 % duty cycle) may
cause RF complaince exposure requirements to 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.
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
10 % in normal PTT configurations. Do not transmit for more than 10 % of the
total radio use time (1:9 duty cycle).
The rear case of the radio can become hot when the radio is used on transmit
for long periods that exceed the Duty Cycle as stated above. In order to protect
the user from the risk of burning if the rear case is touched in these circumstances, the rear case enclosure must be fitted and permanently attached to
the radio using the fixing screws provided whenever the unit is installed in a
position where it is possible during normal usage to touch the rear of the radio.
GX1600EPage 6

5 GETTING STARTED
5.1 ABOUT VHF RADIO
The radio frequencies used in the VHF marine band are 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 5 W 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 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, 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.

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 6 mm 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 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.
GX1600EPage 8
Page 9
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
response, try another channel.
NOTE
The GX1600E have DSC Distress calling, that can transmit a distress
call digitally to all ships with compatible DSC radios. Refer to section “9
DIGITAL SELECTIVE CALLING”.
5.5 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 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-emer-
gency communications. Also hailing on channel 9, the 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, Channels 68 and 69 of the U.S. VHF Charts 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, press the PTT button on the mic
and 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) then
release the PTT button on the mic. When the other vessel returns your call,
immediately request another channel by pressing the PTT button on the mic
and saying “go to,” the number of the other channel, say “over” and release
the PTT button on the mic. Then switch to the new channel. When the new
channel is not busy, call the other vessel.
)
Page 9GX1600E
Page 10
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.
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
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.
5.7 OPERATING ON CHANNELS 13 AND 67
(
USA Channel Group Only
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 23 ( key) for means to temporarily override
the low-power limit on these two channels.

9 DIGITAL SELECTIVE CALLING
9.1 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 shorebased 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).
Digital Selective Calling allows mariners to instantly send a distress call with
GPS position (when connected to the transceiver) to the US 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 Report, Automatic Position Polling and Group calls to or from another
vessel equipped with a DSC transceiver.

9.7 GROUP CALL
This feature allows the user to contact a group of specific vessels (example
members of a yacht club) using DSC radios with Group call function to automatically switch to a desired channel for voice communications. This function
is very useful for yacht clubs and vessels traveling together that want to collectively make announcements on a predetermined channel. Up to 32 Group
MMSI may be programmed.
9.7.1 Group Call Setup
For this function to operate, the same Group MMSI must be programmed into
all the DSC VHF radios within the group of vessels that will be using this
feature. To understand Group MMSI programming, first a Ship MMSI has to be
understood.
Ship MMSI: The first three digits called a MID (Mobile Identity Group) of a Ship
MMSI denote the country the ship registered for a MMSI. The last 6 digits are
specific to the Ships ID.
Ship MMSI Example: If your MMSI is “366123456”, “366” is MID which denote
the country and “123456” is your ships MMSI.
Group MMSI:
FCC or other organizations licensed to assign ship MMSI numbers. Euro-
pean users should check with the local marine regulatory authority in their
country for assistance in assigning a group MMSI number. If permitted to
assign group numbers the following steps should be followed.
The first digit of a Group MMSI is always set to “0” by International rules.
All Standard Horizon radios are preset so when programming a Group
MMSI the first digit is set to “0”.
The USCG recommends programming the MID of a ships MMSI into the
Second, Third and Fourth digits of the Group MMSI as it denotes the area
the ship is located in.
The last 5 digits are decided upon by persons in the Group. This is an
important step as all radios in the Group must contain the same Group
MMSI so they can be contacted by each other. There is a chance that
another group of vessels may program in the same Group MMSI. If this
happens, simply change one or more of the last 5 digits of the Group MMSI.

vessel and show the position of that vessel on the display of the GX1600E.
Standard Horizon has taken this feature one step further, if any compatible
GPS chart plotter is connected to the GX1600E, 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
The other vessel must have an operating GPS receiver connected to its
DSC radio and must not have its radio set not to deny position requests.
(Refer the section “9.5 INDIVIDUAL CALL” to enter information into the
individual directory).

15 RAM3 (CMP30) REMOTE MIC OPERATION
When an optional RAM3 Remote mic is connected to the GX1600E, all VHF,
DSC, setup menus, AIS, Waypoint, and Compass functions can be remotely
operated. The RAM3’s operation is same as GX1600E except the receiver
audio volume setting and squelch level setting. The reason for the same
operation is to make the operation of the radio and RAM3 mic easy. For
specific operation of the RAM3 mic review sections in the radio manual. The
RAM3 is supplied with 7 m of routing cable and can be extended up to 21 m
using three 7 m extension cables model CT-100. The Intercom feature can be
used between the RAM3 and the GX1600E. In addition, speaker wires are
supplied at the panel mount of the routing cable for external speakers to be
connected in noisy environments.
