4 INSTALLATION NOTE
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 watts. The antenna
should be installed 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 where 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 meters of the antenna, nor operated at all if any person is
touching the antenna.
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. Some
radio licenses will require that a timer circuit automatically cuts the transmitter
after 1 - 2 minutes etc.

Attention in Case of Use
This transceiver works on frequencies which are not generally permitted.
For frequency allocation, apply for a licence at
your local spectrum management authority.
For actual usage contact your dealer or sales
shop in order to get your transceiver adjusted
to the allocated frequency range.

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 fixed mount
25W radio transmission expected distances can be greater than 15 miles, for a
portable 5W radio transmission the expected distance can be greater than 5
miles 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 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 6

VM-3500E

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 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 installation of the connector onto the coaxial cable refer to the figure below.
Adapter
1/16''

3/4''
3/4''
1 1/8''
1/8''

3/8'' 5/8''

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.

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
• 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 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.

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), color and

10. If there is no answer, repeat the above procedure. If there is still no response, try another channel.

8.9 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-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, 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
Page 24

VM-3500E

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.

8.10 DUAL WATCH (TO PRIORITY CHANNEL)

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 new 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.

fuse still blows, contact your Dealer.

Popping or whining
noise from the speaker
while engine runs.

Engine noise.

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.

Sound is not emitted
from the internal or external speaker.

Accessory cable.

Check the connections of the accessory cable
(Possible short circuit on the External speaker
cable WHITE/SHIELD).

Receiving station report low transmit
power, even with transceiver set to HI power.

Antenna.

Have the antenna checked or test the transceiver with another antenna. If the problem persists, contact your Dealer for servicing.

“HI BATTERY” or “LO
BATTERY” message is
appeared when the
power is turned on.

The power supply
voltage is too high or
too low.

Confirm that the connected power supply voltage is not 17 volts or lower than 10 volts. Confirm that the generator has not malfunctioned.

“PA ERROR” or “FOG
ERROR” message is
shown when the PA/
FOG mode is activated.

Accessory cable.

Check the accessory cable connection (Possible short circuit on the PA speaker cable RED/
SHIELD).
