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 rst 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 efciency 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 be exceeded.
In all cases any possible risk depends on the transmitter being activated for
long periods (actual recommendation limits are specied 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
10 % in normal PTT congurations. 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 touched in these
circumstances, the rear case enclosure must be fitted and permanently
attached to the radio using the xing screws provided whenever the unit is
installed in a position where it is possible during normal usage to touch the
rear of the radio.

5 GETTING STARTED
5.1 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 es-
sentially “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 xed mount 25W 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, 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 berglass whip is primarily used on power boats that re-
quire the additional gain.
3dB
6dB
9dB

GX1700EPage 8
5.2.1 Coaxial Cable
VHF antennas are connected to the transceiver by means of a coaxial cable
– a shielded transmission line. Coaxial cable is specied 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-213/U should be used. For installa-
tion of the connector onto the coaxial cable refer to the gure below.
To get your coax cable through a tting 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.
5.3 EMERGENCY (CHANNEL 16 USE)
Channel 16 is known as the Hail and Distress Channel. An emergency may
be dened 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 proce-
dure:
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 mag-
netic bearing (state which) to a well-known landmark such as a naviga-
tion aid or geographic feature such as an island or harbor entry.
4. Explain the nature of your distress (sinking, collision, aground, re, 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.

Page 9GX1700E
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 GX1700E 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”.
5.4 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 trafc, congestion on channel
16 resulting from its use as a hailing channel can be reduced signicantly
in U.S. 0waters by using channel 9 as the initial contact (hailing) channel
for non-emergency 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 trafc, 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” fol-
lowed 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

GX1700EPage 10
the PTT button on the mic. 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.
5.5 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 meet-
ing and passing in restricted waters.
Channel 67 is used for navigational trafc between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your ra-
dio 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 25 ( 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
reading 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.
• choose a mounting location that the signal from the GPS satellite can
receive sufciently.
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.
6.2 MOUNTING THE RADIO
6.2.1 Supplied Mounting Bracket
The supplied mounting bracket allows overhead or desktop mounting.
See illustration on next page, use a 5.2 mm bit to drill the holes to a surface

Page 13GX1700E
6.2.2 Optional MMB-97 Flush Mount Bracket
A GPS receiver and antenna is located in the front panel of the GX1700E.
In many cases the radio may be flush mounted, however before cutting
holes to ush mount the radio it is recommended to temporarily connect the
radio to power and turn on in the location where it will be ush mounted to
conrm it is able to receive a GPS location on it’s display. If the radio is not
able to receive a location, a GPS Chart plotter with NMEA 0183 output or the
optional Standard Horizon external GPS antenna may be needed to receive
GPS satellite signals.
To use the optional Standard Horizon external GPS antenna (Q7000619A),
the GX1700E internal GPS Unit Power must be turned OFF (refer to section
“15.1 UNIT POWER”) and the GPS Selection changed to External GPS (refer
to section “15.9 GPS SELECTION”). To mount the GX1700E to a bulkhead
or underside of a shelf, with the bracket on the top of the radio, please follow
these instructions:
1. Remove the heat shield cover from the radio by undoing the screws hold-
ing the cover in place. Store the screws for use later.
2. Identify the hole associated with the Aerial connector at the bottom Right.
3. Using a round 1 cm le remove a 2 mm arc from adjacent to the letter “T”
of the molded word “ANT”.
4. Using the same round 1 cm le remove 2 mm arc from the centre of the
square cutout at the top right hand corner of the heat sink cover.
5.
Rotate the heat sink cover 180 degrees so that the Aerial connector hole
is now top left and offer up to the radio. Ensure that the cables for the DC
power supply, extension loudspeaker and NMEA data cable pass through
the square hole. Secure in place with the two screws from Step 1 above.
6. Verify that the U mounting Bracket can now be positioned to go over the top
of the radio and ts correctly, and can be xed using the two knurled knobs.

Ferrite Core Installation
To suppress RF interference that can cause abnormal operation of
the transceiver, attach the supplied ferrite core to the DC Input Cable,
Accessory Connection Cable, and External Speaker Cable together,
then snap its two halves together, per the illustration below.
Attach the ferrite core as close as possible to the transceiver body, as
shown.
Finally, wind some plastic tape around the ferrite core, to prevent
vibration from causing the two halves to split apart.
Fuse Replacement (125V 6A)
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
