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 operated 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).
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 distance of 0.6 m (2 feet). Failure to observe these restrictions will result in exceeding the FCC RF exposure limits. Antenna Installation: The antenna must be located at least 0.
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.
6 FCC NOTICE NOTICE Unauthorized changes or modifications to this equipment may void compliance 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.

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 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.
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 installation of the connector onto the coaxial cable refer to the figure below.
8 INSTALLATION 8.1 LOCATION The radio can be mounted at any angle.
2. Connect the red power wire to a 13.8 VDC ±20% power source. Connect the black power wire to a negative ground. 3.
