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.
VM-3500EPage 6
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.
1/16''
3/4''
1 1/ 8''
Adapter
3/4''
1/8''
5/8''3/8''
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.
Page 7VM-3500E
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.
6.2 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):

Figure 1. General Installation
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.
VM-3500EPage 8
2. Connect the red power wire to a 13.8 VDC ±20% power source. Connect
the black power wire to a negative ground.
3. If an optional remote extension speaker is to be used, refer to next section
for connections.
4. It is advisable to have a Certified Marine Technician check the power output
and the standing wave ratio of the antenna after installation.
