1  GENERAL INFORMATION
The Vertex Standard GX3500S is a VHF/FM transceiver designed for use in
the frequency range of 156.025 to 163.275 MHz. The GX3500S can be oper-
ated from 11 to 16 VDC and has a switchable RF output power of 1 watt or 25
watts.
The GX3500S is capable of DSC (Digital Selective Calling) Class D operation
and an Enhanced second station RAM+ mic (CMP25 remote-control speaker/
microphone with display). Class D operation allows continous receiving of Digi-
tal Selective Calling functions on channel 70 even if the radio is receiving a call.
Other features of the GX3500S include: Direct keypad entry of a channel using
the keypad, 30W PA/Fog, multi-station intercom, scanning, priority scanning,
submersible speaker mic, high and low voltage warning, and GPS repeatability.

4  SAFETY / WARNING INFORMATION
This radio is restricted to occupational use, work related operations only where
the radio operator must have the knowledge to control the exposure conditions
of its passengers and bystanders by maintaining the minimum separation dis-
tance of 0.6 m (2 feet).
Failure to observe these restrictions will result in exceeding the FCC RF expo-
sure limits.
Antenna Installation:
The antenna must be located at least 0.6 m (2 feet) away from passengers in
order to comply with the FCC RF exposure requirements.

5  FCC RADIO LICENSE INFORMATION
Vertex Standard radios comply with the Federal Communication Commission
(FCC) requirements that regulate the Maritime Radio Service.
STATION LICENSE
An FCC ship station license is no longer required for any vessel traveling in
U.S. waters (except Hawaii) which is under 20 meters in length. However, any
vessel required to carry a marine radio on an international voyage, carrying a
HF single side band radiotelephone or marine satellite terminal is required to
have a ship station license. FCC license forms, including applications for ship
(506) and land station licenses can be downloaded via the Internet at
www.fcc.gov/forms. To obtain a form from the FCC, call (888) 225-5322.
RADIO CALL SIGN
Currently the FCC does not require recreational boaters to have a Ship Radio
Station License. The USCG recommends the boats registration number and
the state to be used.
CANADIAN SHIP STATION LICENSING
You may need a license when traveling in Canada. If you do need a license
contact their nearest field office or regional office or write:

6  FCC NOTICE
NOTICE
Unauthorized changes or modifications to this equipment may void com-
pliance with FCC Rules. Any change or modification must be approved
in writing by Marine Division of Vertex Standard.
NOTICE
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful in-
terference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to ra-
dio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be deter-
mined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.

7  GETTING STARTED
7.1  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 ma-
rine 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.
7.2  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.

7.3  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 installa-
tion 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.

8  INSTALLATION
8.1  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 read-
ing 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 de-
sired 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.
8.2  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):
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.
