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 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 be
exceeded.
In all cases any possible risk depends on the transmitter being activated for
long periods (actual recommendation limits are specied 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 congurations. 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 tted 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 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 xed 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 berglass whip is primarily used on power boats that
require the additional gain.
Page 8
3dB
6dB
9dB
GX1200E
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 specied 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 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 are supplied with the connector.
Be sure to make good soldered connections.
Page 9
GX1200E
5.3 EMERGENCY (CHANNEL 16 USE
Channel 16 is known as the Hail and Distress Channel. An emergency is
dened 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 harbour entry.
4. Explain the nature of your distress (sinking, collision, aground, re, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance you 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
response, try another channel.
)
NOTE
The GX1200E 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 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
signicantly in U.S. waters by using channel 9 as the initial contact (hailing)
channel for non-emergency communications. Here, also, calling time should
Page 10
)
GX1200E
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 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 trafc, 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.
5.5 OPERATING ON CHANNELS 13 AND 67
(USA Channel Group Only)
Channel 13 is used at docks, bridges and by vessels manoeuvring in port.
Messages on this channel must concern navigation only, such as meeting
and passing in restricted waters.
Channel 67 is used for navigational trafc 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.

GX1200E
6 INSTALLATION
6.1 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
• 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 that the 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.

Normally, the GND connection to the heat sink is not needed. However,
when the DC power cable connection to the radio has a long run, the
transmitter may become unstable and the receiving audio may be noisy.
In such a case, connect a large diameter, short cable between this terminal on the heat sink and battery ground.
Install only the supplied screw or similar size (M3x6, Stainless
Steel) screw.

1. After the GX1200E has been installed, ensure that the power supply and
antenna are properly connected.
2. Turn the VOL/PWR knob clockwise to turn the transceiver on.
3. Turn the SQL knob fully counterclockwise. This state is known as “squelch
off”.
4. Turn up the VOL knob until noise or audio from the speaker is at a
comfortable level.
5. Turn the SQL knob clockwise until the random noise disappears. This
state is known as the “squelch threshold.”
6. Press the
channel chart on page 98 for available channels.
7. When a message is received, adjust the volume to the desired listening
level. The “ ” indicator on the LCD is displayed indicating that the
channel is being used.
8.2 TRANSMISSION

NOTE
This is a noise cancelling microphone. The oval slot on the microphone should be positioned within 1.3 cm from the mouth for
optimum performance.
5. When the transmission is nished, release the PTT switch.
8.3 TRANSMIT TIME-OUT TIMER (TOT
When the PTT switch on the microphone is held down, transmit time is limited to 5 minutes. This limits unintentional transmissions due to a stuck microphone. About 10 seconds before automatic transmitter shutdown, a warning
beep will be heard from the speaker(s). The transceiver will automatically
go to receive mode, even if the PTT switch is continually held down. Before
transmitting again, the PTT switch must rst be released and then pressed
again.
